The objective was to evaluate the electrophoretic profile of proteins and serum concentration of immunoglobulin G (IgG) in Saanen goats with mastitis experimentally induced by Staphylococcus aureus (dl-a-tocopherol acetated). 14 adult goats, (supplemented with vitamin E DL-a-tocopherol) primiparous pregnant, seronegative for caprine arthritis encephalitis (CAEV), clinically healthy, were divided into two groups of seven animals: Not supplemented group (G1) and group supplemented with 2.000 UI of DL-a-tocopherol (G2 Vit E), by intramuscular injection on the day of the parturition and seven days later. At the 9th day after delivery 300 UFCs of the S. aureus ATCC 225923 strain were inoculated into the left half of the mammary gland of each animal. The mastitis was determined through collection of milk samples for evidence of infection by means of bacteriological examination, somatic cell count (SCC) and California Mastitis Test (CMT). Then samples were collected after 12, 24, 48 and 72 hours, antimicrobial intra-mammary gland treatment was initiated, with new evaluation 48 hours after treatment. The electrophoretic profile of serum protein of the goats, showed five fractions, as follows: albumin and globulin (a, b1, b2 e g-globulin). There was an increase in the production of g-globulin and lower production of b2-globulin fraction 12 hours after infection, and faster decrease in the supplemented group, showing the influence of vitamin E in the production of acute phase proteins. There was no influence of vitamin E in the serum concentration of immunoglobulin G (IgG) in supplemented animals. The supplementation with vitamin E increased the concentration of immunoglobulin and decreased the production of acute phase proteins, probably the antioxidant effect minimizing the tissue injury during the inflammatory process in the mammary gland.

O objetivo do trabalho foi avaliar o perfil eletroforético das proteínas e a concentração sérica de imunoglobulina G (IgG) em cabras da raça Saanen com mastite induzida experimentalmente por Staphylococcus aureus e suplementadas com vitamina E (acetato de dl-a-tocoferol). Utilizaram-se 14 cabras adultas, gestantes, primíparas, com sorologia negativa para Artrite Encefalite Caprina (CAEV), clinicamente sadias, divididas em dois grupos experimentais de sete animais. Grupo não suplementado (G1) e grupo suplementado com 2.000 U.I. de acetato de dl-a-tocoferol (G2 Vit E) via intramuscular no dia do parto e sete dias após o parto. Ao nono dia do pós-parto foram inoculados 300 UFCs da cepa de S. aureus ATCC 225923, na metade esquerda da glândula mamária de cada animal. A mastite foi determinada pela colheita das amostras de leite para a comprovação da infecção, por meio de exames bacteriológicos, contagem de células somáticas (CCS) e California Mastitis Test (CMT), a partir deste momento foram efetuadas colheitas às 12, 24, 48 e 72 horas, sendo posteriormente instituído o tratamento intramamário com antimicrobiano e nova avaliação 48 horas após o tratamento. O perfil eletroforético em gel de agarose das proteínas séricas das cabras, apresentaram cinco frações, sendo: albumina e globulinas (a, b1, b2 e g). Houve aumento na produção de g-globulina e menor produção da fração b2-globulina 12 horas após a infecção, com os valores reduzindo mais rapidamente no grupo suplementado, evidenciando a influência da vitamina E na diminuição da produção das proteínas de fase aguda. Não houve influência da vitamina E na concentração sérica de imunoglobulina G (IgG) nos animais suplementados. A suplementação com vitamina E aumentou a concentração de imunoglobulinas e diminuiu a produção de proteínas de fase aguda, provavelmente pelo efeito antioxidante minimizando a lesão tecidual durante o processo inflamatório localizado na glândula mamária.

The study evaluated and compared the aerobic microbiota from the oral cavity, cloaca and venom of Crotalus durissus terrificus snakes, recently caught from the wild and kept under quarantine (WQ), individual captivity (IC) and collective captivity (CC). Antimicrobial drug effectiveness on isolated agents also was assayed. From group I, II and III were isolated, respectively, 29 (63.04%), 38 (90.48%) and 21 (42.86%) microorganisms from the cloaca; 15 (32.61%), 3 (7.14%) and 25 (51.02%) microorganisms from the oral cavity; and, 2 (4.35%), 1 (2.38%) and 3 (6.12%) microorganisms from venom. The most frequent bacteria were Pseudomonas aeruginosa, Proteus vulgaris and Morganella morganii, with sensitivity to amikacin, gentamicin, norfloxacin, sulfazotrin and tobramycin. Snakes kept in semi-open captivity exhibited the fewest microorganisms in oral cavities, perhaps due to the environment in captivity, with different temperature gradients, running water, absence of daily handling, circulating air, possibility of moving around, daily cleaning, and sunlight access.

Este estudo avaliou e comparou a microflora aeróbica da cavidade oral, cloaca e veneno de serpentes Crotalus durissus terrificus recém-capturadas da natureza e mantidas sob quarentena (WQ), mantidas em cativeiro coletivo (CC) e em cativeiro individual (IC). A eficácia de drogas antimicrobianas de agentes isolados foi também avaliada. Foram isolados microorganismos dos grupos I, II e III respectivamente: 29 (63.04%), 38 (90.48%) e 21 (42.86%) da cloaca; 15 (32.61%), 3 (7.14%) e 25 (51.02%) da cavidade oral, e finalmente 2 (4.35%), 1 (2.38%) e 3 (6.12%) do veneno. As bactérias mais frequentes foram Pseudomonas aeruginosa, Proteus vulgaris e Morganella morganii, com sensibilidade para amikacina, gentamicina, norfloxacina, sulfazotrina e tobramicina. Serpentes mantidas no cativeiro semi-aberto mostraram menor número de agentes infecciosos em cavidade oral, talvez devido ao ambiente de cativeiro com diferentes gradientes de temperatura, água corrente, ausência de manejo diário, ampla circulação de ar, possibilidade de movimentação pelos animais, limpeza diária e acesso ao Sol.

The efficacy of a polyvalent bacterin vaccine against Aeromonas hydrophila, Pseudomonas aeroginosa and Enterococcus durans administered by different routes in Nile tilapia was assessed by analyzing hematological and immunological parameters 7 and 21 days after vaccination. Treatments consisted of: non-vaccinated tilapia; tilapia vaccinated by intraperitoneal injection with 2x108 formalin-inactivated bacteria·mL-1; tilapia vaccinated orally with 2x107 formalin-inactivated bacteria·g-1, feed for 5 days; tilapia vaccinated by immersion bath in 2x107 formalin-inactivated bacteria·mL-1, for 20 minutes. Vaccinated fish groups presented higher hematocrit, number of erythrocytes and leukocytes than the non-vaccinated group. Serum agglutination titer of intraperitoneally vaccinated fish was higher on both evaluation periods for the three bacteria strains. Only on day 21 post-vaccination fish from the oral and immersion vaccination groups presented higher serum agglutination titer than the non-vaccinated fish for A. hidrophyla and E. durans. Serum antimicrobial activity in vaccinated fish was higher for P. aeroginosa and E. coli than in non-vaccinated fish on both evaluation periods. The different vaccine administration routes stimulated hematological and immunological responses in Nile tilapia 21 days post-vaccination, but intraperitoneal vaccination presented higher total number of leukocytes, lymphocytes and serum agglutination titer.

Este estudo avaliou a eficácia da administração de vacina polivalente (bacterina), contra Aeromonas hydrophila, Pseudomonas aeroginosa e Enterococcus durans, por diferentes vias de aplicação em tilápia do Nilo, analisando parâmetros hematológicos e imunológicos no 7º e 21º dia após vacinação. Os tratamentos consistiram de: tilápias não vacinadas; tilápias vacinadas via injeção intraperitoneal (i.p.) contendo 2x108 bactérias inativadas·mL-1; tilápias alimentadas com ração contendo vacina na proporção de 2x107 bactérias inativadas·g-1, durante 5 dias; tilápias vacinadas por banho de imersão em 2x107 bactérias inativadas·mL-1, durante 20 minutos. Os peixes vacinados apresentaram maior porcentagem de hematócrito, número de eritrócitos e leucócitos durante o período do experimento, em relação aos não vacinados. O título de aglutinação do soro dos peixes vacinados intraperitonealmente foi superior nos dois períodos de avaliação para todas as bactérias. Apenas no 21º dia os peixes vacinados oralmente e por imersão apresentaram título de aglutinação superior aos peixes não vacinados para A. hidrophyla e E. durans. O soro dos peixes vacinados apresentou maior atividade antimicrobiana para P. aeroginosa e E. coli, do que os peixes não vacinados, nos dois períodos. As diferentes vias de administração da vacina estimularam a resposta hematológica e imunológica da tilápia do Nilo após 21 dias de vacinadas, sendo que o número total de leucócitos, linfócitos, título aglutinante do soro dos vacinados i.p. foi maior do que os demais.

Stephanofilariasis is a worldwide disease caused by the nematode Stephanofilaria that determines skin lesions. In cattle, the chronic dermatitis is characteristic begining with papules that progress to nodules, alopecia and ulcers with crusts. Despite it’s long time recognition, there are few studies and reports about this disease, specially in Brazil. This work was conducted in order to investigate epidemiological and clinical features of stephanofilariasis in dairy cows and to compare two methods for the diagnosis confirmation. Fifty-eight naturally affected dairy cows from seven herds located in Santana do Itararé, state of Paraná, and Itaberá, state of São Paulo, were studied from January 2006 through August 2008. Two methods for the diagnosis confirmation were compared using biopsied tissues from the border of the skin lesion: the histopathological examination (n=24) and the direct sediment examination of an isotonic saline solution in which the tissue fragment remained soaked (n=20). The prevalence was higher from December to March (57%) and lactating cows were primarily affected (87,9%). The cranial aspect of the fore mammary glands was the main site of the skin lesions (96,7%), chiefly near the ventral midline (55%). The characteristic wound was of circular shape, ulcerated with crusts and serosanguineous exudation. Chronic dermatitis with eosinophilic and mononuclaer cell infiltrates was the histopathologic change pattern present. The parasite was not detected in any histologic section examined. The direct sediment examination otherwise proved to be efficient for the diagnosis confirmation revealing the nematode adult and larval forms in all the specimens.

A estefanofilariose é uma doença mundialmente distribuída e caracteriza-se por lesões na pele causadas por nematódeo do gênero Stephanofilaria. Nos bovinos manifesta-se por uma dermatite crônica associada com erupção papular progredindo para nódulos, alopecia e ulceração crostosa. Apesar de reconhecida há muitos anos, há poucos estudos e relatos sobre a mesma. A literatura é particularmente escassa no Brasil. Esse trabalho teve como objetivos investigar aspectos epidemiológicos e clínicos da estefanofilariose em vacas leiteiras naturalmente acometidas e comparar dois métodos para a confirmação do diagnóstico, o exame histopatológico e o exame direto. Foram investigados aspectos clínicos relacionados à ocorrência natural da estefanofilariose em 58 vacas de leite de sete rebanhos criados nos municípios de Santana do Itararé, PR e de Itaberá, SP durante o período de janeiro de 2006 a agosto de 2008. Dois métodos foram comparados para confirmação do diagnóstico a partir de tecido colhido por biópsia da borda das lesões, o histopatológico (n=24) e o exame direto do sedimento da solução salina isotônica na qual o tecido permaneceu embebido (n=20). A maior prevalência ocorreu de dezembro a março (57%) e a maioria das vacas era lactante (87,9%). As lesões se localizavam nos quartos anteriores do úbere em seu aspecto cranial (96,7%), principalmente próximo à linha média (55%). A lesão típica tinha formato circular era ulcerada com crostas e exibia exsudato sero-sanguinolento. No exame histopatológico evidenciou-se uma dermatite crônica com infiltrado mononuclear e eosinofílico. A presença do parasita não foi detectada em nenhum dos cortes examinados. O exame direto possibilitou a demonstração do agente em todas as amostras examinadas, comprovando-se como um método eficiente para a confirmação do diagnóstico.

As formas de imobilização em bovinos mais utilizadas levam a uma manipulação excessiva e consequentemente estressante para o animal. A dor é uma experiência emocional de sensação desagradável que vem associada a um prejuízo tecidual. Surge no mercado um método de contenção física para bovinos que propõe a utilização de um aparelho que funciona com ondas eletromagnéticas de baixa intensidade promovendo imobilização sem estresse e ou estímulo doloroso para o animal. O objetivo deste projeto foi avaliar os parâmetros cardiorrespiratórios e hemogasométricos bem como os níveis de cortisol de bovinos submetidos à imobilização eletromagnética, a fim de observar se tal método é eficaz na diminuição do estresse e/ou estímulo doloroso. Foram utilizados 6 bovinos, mestiços, peso médio de 300,3 kg (±85,76). Os animais foram alocados aleatoriamente em dois grupos (controle dele mesmo): grupo controle (GC), introdução da sonda via retal (desligada); grupo Imobilizador (GI) introdução da sonda e permanência desta ligada por 5 minutos. Análise estatística utilizou o Teste T pareado entre os grupos (P<0,05) e a avaliação entre tempos dentro de cada grupo análise de variância de uma única via com repetições múltiplas (ANOVA - RM). Momentos avaliados M0: basal; M1: imediatamente após a retirada da sonda; M2 e M3 (30 e 60 minutos após M1 respectivamente). Houve um aumento significativo nas variáveis: frequências cardíaca e respiratória em (M1), na Pressão arterial média (M1, M2, M3) e níveis de cortisol nos momentos M1 e M2 no grupo imobilizador quando comparado ao grupo controle. Com relação à resposta ao estímulo, o GI teve resposta negativa no momento da estimulação, comparado ao GC (resposta máxima). De acordo com os resultados obtidos, podemos concluir que o imobilizador eletromagnético é um método, exclusivamente, de contenção física, não oferecendo nenhum suporte anestésico, para o conforto ou bem estar ao animal.

The ways of immobilization generally used in cattle provide excessive manipulation and stress for the animal. The pain is an emotional experience and unpleasant sensation in combination with tissue damage. The new method of physical restraint for cattle uses low intensity electromagnetic waves, promising immobilization without stress or painful stimulation for the animals. The aim of this study is to evaluate of cardiorespiratory effects and plasmatic cortisol concentration of cattle submitted to electromagnetic immobilization. Six healthy cows with average weight of 300.3 ± 85.76 kg (mean ± SD) were assigned to two treatments in a randomized design with a 15-day interval between experiments GC (control group) and GI (immobilization group). Data are presented as mean + SD. The statistical analyses used the t-Test between groups, and ANOVA random block design between times into same group. All statistical analyses were performed using P<0.05 as a significant level. Evaluation moments: M1 (basal); M1: after withdrawal probe, M2 and M3 (30 and 60 minutes after M1 respectively). There was a significant increase of FC and f in M1, PAM in the moments (M1, M2, M3) and in the levels of plasmatic cortisol concentration in M1 e M2 in the immobilization group when to compared with the control group. It could be concluded that this electromagnetic immobilization is a method of physic restraint only, offers no anesthetic support and favors comfort and animal welfare.

In the last few years, the use of laparoscopy in veterinary medicine has expanded and consequently so was the need for studies that establish the advantages, disadvantages and possible complications of each procedure. The purpose of the current study was to describe a laparoscopic splenectomy technique and the alterations due to this access, and compare it to the open procedure in dogs. A total of 15 healthy female mongrel dogs were used, with mean weight of 17.4±2.5kg. The animals were distributed into three groups: Group IA of open splenectomy (laparotomy) using double ligation of the vessels of the splenic hilum with poliglicolic acid, Group IB of open splenectomy (laparotomy) with bipolar electrocoagulation of the splenic hilum, and Group II of laparoscopic access with bipolar electrocoagulation of the splenic hilum. Operative time, blood loss, size of incisions, complications during and after surgery were evaluated. Other parameters included pain scores, white blood cell (WBC) counts and postoperative serum concentrations of alanine aminotransferase (ALT), alkaline phosphatase (ALP), creatine kinase (CK), C-reactive protein (CRP), glucose and cortisol. No differences were found in the evaluation of parameters between both open splenectomy techniques employed. Laparoscopic access presented significant differences (p<0,05) when compared with open surgery: Longer operative time, smaller abdominal access, decrease in blood loss, lower concentrations of CRP, higher levels of CK and ALP, and lower scores in the pain scale. Laparoscopic surgery showed fewer complications of the surgical wound. No significant differences were observed between groups in the postoperative temperature, WBC, ALT, cortisol and glucose concentrations. In conclusion, the laparoscopic technique is useful for splenectomy in dogs, being advantageous in terms of blood loss, surgical stress and surgical wounds. However, it expends more operative time and causes transitory increase in hepatic and muscular enzymes.

Nos últimos anos, a utilização da laparoscopia em Medicina Veterinária vem expandindo e, conseqüentemente, a necessidade de pesquisas que determinem as vantagens, desvantagens e possíveis complicações de cada procedimento. Este estudo teve como objetivo descrever uma técnica de esplenectomia laparoscópica, assim como as alterações decorrentes deste acesso, e compará-la ao procedimento convencional em cães. Foram utilizadas 15 cadelas hígidas, sem raça definida, com peso médio de 17,4 ±2,5kg. Os animais foram distribuídos em três grupos: Grupo IA de acesso convencional (por laparotomia) utilizando ligadura com ácido poliglicólico no selamento vascular do hilo esplênico, Grupo IB de acesso convencional (por laparotomia) com eletrocoagulador bipolar do hilo esplênico, e Grupo II de acesso laparoscópico com eletrocoagulador bipolar para selamento vascular dos ramos esplênicos. Estes grupos foram avaliados em relação ao tempo cirúrgico, à perda de sangue, ao tamanho das incisões e às complicações durante e após a cirurgia. Também foram comparadas as avaliações da escala de dor e as alterações no leucograma e nas concentrações séricas da alanina aminotransferase (ALT), da fosfatase alcalina (FA), da creatina quinase (CK), da proteína C-reativa (CRP), da glicose e do cortisol no pós-operatório. Os acessos convencionais não diferiram entre si nos parâmetros avaliados. O acesso laparoscópico apresentou diferenças significativas (p<0,05) quando comparado ao convencional: maior tempo cirúrgico, menor acesso abdominal, diminuição na perda de sangue, menores concentrações de CRP, maiores níveis de CK e FA, além de pontuação menor na escala de dor. A cirurgia laparoscópica apresentou menor número de complicações das feridas cirúrgicas. A ALT, o cortisol, a glicemia, o leucograma e a temperatura retal pós-operatórias não diferiram significativamente entre os acessos convencional e laparoscópico. Conclui-se que a cirurgia laparoscópica é viável para esplenectomia em cães, apresentando vantagem em relação à perda de sangue, ao estresse cirúrgico e às feridas cirúrgicas, embora apresente maior tempo cirúrgico e cause aumento transitório de enzimas hepática e muscular.

Paratuberculosis is a chronic enteric disease of ruminants caused by Mycobacterium avium subsp. paratuberculosis. Culture of bacteria from faeces and tissues samples constitutes one of the most effective methods of confirming the diagnosis of para-tuberculosis and the only method available to obtain strains of mycobacteria. However, this method is less sensitive and requires months of incubation before colony growth occurs. In this study, culture method was used on sheep faeces to diagnose paratuber-culosis in animals with compatible signs of the disease. A comparison of two culture media used to isolation was also investigated. Culture was positive in 2.0% of faecal samples. Isolation was obtained using Löwenstein Jensen® with mycobactin® J, and the Middlebrook® 7H11 with OADC®. The Löwenstein Jensen® with mycobactin® J was that provided highest amount of isolations. The percentages of isolation in each culture media were 2.0% (6/300) to Löwenstein Jensen® with micobactina J, and 1.0% (3/300) to Middlebrook® 7H11/OADC. The three positive samples in Middlebrook® 7H11/OADC were also positive in Löwenstein Jensen® with micobactina J. In the Middlebrook® 7H11/OADC alone there was no sample growth. The results of this study suggest that culture media of Löwenstein-Jensen® with micobactina® J is more effective for the isolation of sheep strains in Portugal.

The percentages of isolation in each culture media were 2.0% (6/300) to Löwenstein Jensen® with micobactina J, and 1.0% (3/300) to Middlebrook® 7H11/OADC. The three positive samples in Middlebrook® 7H11/OADC were also positive in Löwenstein Jensen® with micobactina J. In the Middlebrook® 7H11/OADC alone there was no sample growth. The results of this study suggest that culture media of Löwenstein-Jensen® with micobactina® J is more effective for the isolation of sheep strains in Portugal.

Due to the increasing use of cortical bone allografts in orthopedic surgeries, de knowledge of its biomechanics characteristics during preservation time is needed. The present study consisted in the analyses of the resistance power to the micro-traction of samples of rabbit cortical bones preserved in several means for up to 180 days and fresh. The results showed that the resistance and the preservation time presented an inversely proportional relation, meaning that, the longer the time of preservation, the shorter the physical resistance evaluated in the biomechanical rehearsal of resistance to the micro-traction. The glycerin has presented lower values in relation to the resistance test, showing, after 30 days, only 24.58% of the present power in the fresh bone, and by 180 days, 1.76%. The samples submitted to autoclavation also showed low values by the end of the experiment, while they remained with just 12.31% of the power present in the fresh bone. The bones preserved in homologous plasma, Dakin liquid and the ones cryopreserved showed the best levels of resistance at the end of the experiment, remaining, respectively with 82.47, 70.34 and 66.72% of the maximum power, while compared with the resistance of the fresh bones. The conclusion is that the choice of methodology and time of preservation interfered directly in the biomechanics of the cortical bones, promoting decrease of the resistance capacity to the traction along the period of preservation.

The objective was to genotypically compare 35 samples of Corynebacterium pseudotuberculosis obtained from abscesses of sheep and goats diagnosed with caseous lymphadenitis originated from 5 different municipalities in the semi-arid region of Pernambuco, Brazil. The RFLP-PCR technique with Hpy-Ch4 and Msp I and Pst I Msp I restriction enzimes was used to fingerprint the genes rpoB and pld, respectively. The results demonstrate that there was no difference on the fragments banding pattern among samples, independently of the host species or geographic area studied, defining a homogeneous profile of C. pseudotuberculosis responsible for superficial abscesses for the region.

[Comparison of the application of temporary endodontic dressing in teeth of dogs: histopathological and microbiological aspects.] Comparação entre sessão única e a utilização do “curativo de demora” no tratamento endodôntico em cães: aspectos histopatológicos e microbiológicos.

During a root canal therapy the microbiota is the major concern. Bacteria present in dentinal tubules, apical foramens and apical delta is related to failure of this procedure. Some studies reveal that during endodontic treatment in one session bacteria still remain in dental structures. The aim of the present study was to evaluate the endodontic treatment in one or two sessions, using calcium hydroxide plus camphorated paramonochlorophenol (CMCP) with temporary endodontic medicaments. Four dogs were used, and two animals were submitted the treatment in one session only and the others in two sessions. Premolar teeth were used in this study: second and third upper premolar teeth and second, third and fourth lower premolar teeth were divided into two groups. Opening of the pulp chamber was performed with burns, and the pulp was exposed for 60 days. After this period the group treated in only session was obtured with gutta-percha and zinc oxide and eugenol, and the group treated in two sessions received the CMCP that remained in the canal per 30 days and was afterwards obtured with the material of the other group. Clinical and radiographical control was performed twice a week, and after 60 days a small block containing the teeth, surrounding periapical tissues and the periodontium was removed for histological and microbiological study. Histological analysis revealed intense inflammatory response in both groups. Microbiological analysis showed a more severe microbial reduction in the group treated in one session. However, bacteria were still observed in the two groups, indicating that none of the treatments presented total efficiency.
