Alberto Lamego 2000, Horto, Campos dos Goytacazes, RJ 28013-602, Brazil. E-mail: olney@uenf.br Pythiosis is caused by Pythium insidiosum and the occurrence of disease in horses was described in the North and Northwest State of Rio de Janeiro, Brazil. The disease was described in cattle, sheep, humans, and horses in different states and regions across the country. This paper describes the development of IgY and IgG polyclonal antibodies, in chicken and rabbits, respectively against proteins extracted from kunkers and hyphae of P. insidiosum from affected horses. The proteins were recognized by chicken, rabbit and horse antibodies by immunodiffusion and Western blot against majority bands of 27 and 43 KDa, and titrated by ELISA. The antibodies IgY developed by the first time against Brazilian strains of P. insidiosum may represent a valuable tool in the detection of antigens of the pathogen and contribute to further studies aimed at immunotherapy and knowledge about this disease in endemic areas in Rio de Janeiro and in Brazil.

E-mail: carregaro@smail.ufsm.br The aim of the study was to verify the influence of the body temperature under physiological values and latency and recovery times on rattlesnakes anesthetized with ketamine. The animals were previously submitted to hypothermia (HYPO) (<22°C) and normothermia (30°C) (NORMO) and then, anesthetized with 80 mg/kg IM of ketamine. Latency and recovery times were evaluated by head tonus, muscular tonus and righting reflex. Heart rate (HR), time of apnea and body temperature were measured before and 5, 10, 15, 30, 60, 90 and 120 minutes after ketamine administration. Blood gases parameters were measured before, 30 and 60 minutes. It was not observed difference on latency time in both groups. The recovery time was higher on HYPO (5,5 hours) compared to NORMO (3,5 hours). HR was higher on NORMO compared to HYPO. Time of apnea was the same pattern on both groups. Compared to basal levels, time of apnea was shorter between 5 to 30 min on both groups. Respiratory acidosis was observed only at 0 min in NORMO. SvO2 was higher after 30 min, the same as with PvO2 in both groups. PvCO2 reduced after 30 min in both groups. It was evident that body temperature exerts intense influence on the recovery time on rattlesnakes anesthetized with ketamine.

E-mail: carregaro@smail.ufsm.br O estudo objetivou verificar a influência da temperatura corporal nos parâmetros fisiológicos e nos períodos de indução e recuperação anestésicos de cascavéis (Crotalus durissus) anestesiadas com cetamina. Os animais foram previamente submetidos à hipotermia (HIPO) (<22°C) e normotermia (30°C) (NORMO) e anestesiados com 80mg/kg IM de cetamina. Foram avaliados os períodos de latência e recuperação da anestesia por meio do tônus de cabeça, tônus muscular e reflexo de endireitamento. Mensurou-se a frequência cardíaca (FC), tempo de apnéia e temperatura corporal em 0 min e 5, 10, 15, 30, 60, 90, 120 min e análise dos gases sanguíneos em 0 min, 30 e 60 min. Não houve diferença em relação ao período de latência entre os grupos. A recuperação dos animais em HIPO foi mais prolongada (5,5 horas) que em NORMO (3,5 horas). Obteve-se FC no grupo NORMO superior que no grupo HIPO. O tempo de apnéia manteve o mesmo padrão em ambos os grupos. Em relação ao basal, tanto em HIPO quanto em NORMO o tempo de apnéia diminuiu acentuadamente entre 5 e 30 min. Observou-se acidose respiratória no grupo NORMO apenas em 0 min. O SvO2 elevou-se significativamente após 30 min, o mesmo ocorrendo com a PvO2. A PvCO2 diminuiu em ambos os grupos após 30 min. Evidenciou-se que a temperatura corporal influencia intrinsecamente o período de recuperação de cascavéis anestesiadas com cetamina.

E-mail: ana6113@hotmail.com A retrospective study was conducted to identify the occurrence and types of ocular disorders in 57 Amazon parrots admitted to the Ophthalmology Service, Veterinary Teaching Hospital, School of Veterinary Medicine, University of São Paulo, Brazil from 1997 to 2006. The most frequent observed disorder was cataracts, present in 24 of the 114 examined eyes (57 parrots). Uveitis, ulcerative keratitis and keratoconjunctivitis were frequently diagnosed as well. The cornea was the most affected ocular structure, with 28 reported disorders. Uveal disorders also were commonly observed. Conjunctiva and eyelid disorders were diagnosed in lower frequency. Results suggest that cataracts are common and that cornea, lens and uvea are the most affected ocular structures in Amazon parrots.

#354 - Assessment of blood inflammatory response in BCG stimulated rattlesnakes (Crotalus durissus Linnaeus, 1758), 29(12):985-992

Abstract in English:

ABSTRACT.- Silva W.B., Machado C., Goldberg D.W., Moreira S.B., Silva L.C.C.P., Freire I.M.A., Maciel P.O. & Almosny N.R. 2009. [Assessment of blood inflammatory response in BCG stimulated rattlesnakes (Crotalus durissus Linnaeus, 1758).] Avaliação da resposta hematológica em cascavéis (Crotalus durissus Linnaeus, 1758) inoculadas com BCG.

Programa de Pós-Graduação em Clínica e Reprodução Animal, Faculdade de Medicina Veterinária, Universidade Federal Fluminense, Rua Vital Brazil Filho 64, Niterói, RJ 24230-360, Brazil. E-mail: wellban@yahoo.com.br The high demand for anti-venom production in response to the increased number of cases of snakebite envenomation highlights the importance of raising and breeding venomous snakes in captivity. Knowledge of types of venoms and anti-venoms is of great interest to public health. The maintenance of venomous serpents in captivity started in the early twentieth century, but still nowadays it is a challenge to manage and prevent diseases in captive fauna. Hematology is commonly used for general health assessment and illness detection. However, data on serpent blood analysis are still scarce. Alterations in hematological parameters were experimentally induced in rattlesnakes by the inoculation of BCG. Based on this, hemograms can be used as a health auxiliary diagnosis method for bacterial diseases in this species. In this study, blood samples were taken from 10 healthy specimens of rattlesnakes (Crotalus durissus) born and bred in captivity in the Herpetological Division of Vital Brazil Institute. Animals were divided into two groups (group 1 and 2) with similar live weight and sex proportion, and were then inoculated subcutaneously with BCG (Bacillus Calmette-Guérin). Blood samples were taken before and after inoculation at three experimental times (days 3, 5 and 7 for group 1 and days 11, 17 and 21 for group 2). Hematological analysis was performed through semi-direct technique, blood samples were diluted in Natt and Herrick solution and smears were stained by Giemsa. Serpents from group 1 developed discrete anemia due to the inflammatory syndrome, and showed significant decrease of MCH and MCHC. Granulocytes were characterized by the presence of rough granules. The azurophils varied in shape and size and showed large amount of cytoplasmic vacuoles. The thrombocytopenia observed in group 2 suggests that these cells participate in the inflammatory process. A single individual from group 1 showed granulocytosis and a few animals showed a discrete azurophilia. In general, BCG inoculation unleashes hematological inflammatory responses characterized by the presence of thrombocytes, azurophils and granulocytes cells.

E-mail: wellban@yahoo.com.br A criação de serpentes peçonhentas em cativeiro para produção de soros antipeçonhas possui crescente importância para a saúde pública devido ao aumento do número de notificações de acidentes ofídicos a cada ano no Brasil. Iniciado no século XX, ainda hoje essa atividade apresenta alguns desafios como a instalação de doenças no plantel. O hemograma é um exame de triagem clínica que auxilia no diagnóstico de diversas moléstias que acometem diferentes espécies de animais, no entanto ainda pouco estudado em serpentes. A caracterização das alterações hematológicas em cascavéis inoculadas experimentalmente com BCG pode servir de base na utilização deste exame no auxílio ao diagnóstico de infecções bacterianas na espécie. Dessa forma, foram realizados exames hematológicos em 10 serpentes da espécie Crotalus durissus pertencentes ao plantel da Divisão de Herpetologia do Instituto Vital Brazil. Os animais foram divididos em dois grupos (Grupos 1 e 2), homogêneos entre si em relação ao peso e proporção sexual. Os dois grupos foram inoculados com BCG e submetidos à coleta de sangue antes da inoculação e em três momentos pós-inoculação (3º, 5º, e 7º dias para o Grupo 1 e 11º, 17º e 21º dias para o Grupo 2). O hemograma foi realizado por método semidireto pela utilização de líquido de Natt e Herrick e as lâminas foram coradas pelo Giemsa. Observou-se anemia discreta, com redução dos valores de concentração de hemoglobina corpuscular média e da hemoglobina globular média no Grupo 1 que foi relacionada à doença inflamatória. A trombocitopenia observada no Grupo 2 sugeriu a atuação deste tipo celular em processos inflamatórios. Um único animal do Grupo 1 apresentou granulocitose e alguns animais apresentaram discreta azurofilia. Observaram-se alterações morfológicas nos leucócitos. Os granulócitos apresentaram granulações grosseiras e os azurófilos apresentaram aumento de tamanho e grandes vacúolos. De forma geral, a inoculação de BCG em cascavéis desencadeia respostas inflamatórias hematológicas caracterizadas pela participação de trombócitos, granulócitos e azurófilos.

E-mail: rseabra@cevap.org.br 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.

E-mail: aemurakami@uem.br An experiment was carried out to evaluate the effect increasing levels of yeast wall and broiler breeders’ age levels on lymphoid organs weight, cellular immune response and hematological parameters in broilers. A total of 3,360 Cobb broilers were allotted, in a completely randomized design and a 2x5 factorial arrangement, and two controls, compound of two broiler breeders age (34 and 57 weeks of age) and five yeast wall levels (zero, one, two, three and four kg of yeast wall/ton of diet). Broiler breeders’ age affected all studied variables. The inclusion of 3kg of yeast wall/ton of meal increased, at 57 weeks age broiler breeders, more intense inflammatory reaction when compared to control diet; however the circulated heterophils and lymphocytes numbers were not increased. In conclusion, the use of yeast wall, associated or not to sorghum on broilers diet still needs complementary studies, for example, purified components of yeast wall (MOS and ß-glucano).

Foram utilizados 3.360 pintos de corte da linhagem Cobb, distribuídos em delineamento inteiramente casualisado, em esquema fatorial 2x5, mais dois controles, sendo duas idades de matrizes (34 e 57 semanas de idade) e cinco níveis de suplementação de parede de levedura (zero, um, dois, três e quatro kg de parede de levedura/tonelada de ração). A idade das matrizes influenciou a resposta de todas as variáveis. A inclusão de 3kg de parede de levedura/tonelada de ração promoveu, na progênie de reprodutoras de 57 semanas, reação inflamatória mais intensa quando comparada a dieta controle, no entanto não houve aumento significativo no número de heterófilos e linfócitos circulantes. Conclui-se que a utilização da parede de levedura associada ao sorgo ou não em rações de frangos de corte ainda necessita de estudos complementares, que incluam, por exemplo, os componentes purificados da parede de levedura (MOS e ß-glucano).

E-mail: everton_unesp@yahoo.com.br Attempting to avoid difficulties associated to triple pelvic osteotomy (TPO), the sacroiliac wedge method was experimentally developed to increase the acetabular ventroversion. The goal of this study was to apply the techniques of sacroiliac wedge and TPO to canine cadavers and radiographically evaluate the efficacy of acetabular ventroversion. Ten cadavers of adult dogs weighting 15-25 kg were used. To each right hemipelvis the technique of TPO with 20° and 40° plates was applied. In the left hemipelvis, 20° and 40º wedges in the sacroiliac joint were applied. Radiographic evaluations in standard projections were carried out for measurement of the acetabular covering of the head of the femur in the two techniques. There was no significant differences between TPO and the use of sacroiliac wedge using implants of 20° and 40°, however a significant difference (p<0,05) could be observed before and after application of the 20° and 40° implants, as well as between those that received 20° and of 40° implants. The application of sacroiliac wedge produced similar results of those observed in TPO, and it is more feasible.

E-mail: everton_unesp@yahoo.com.br Na tentativa de evitar algumas das dificuldades associadas à osteotomia pélvica tripla (OPT), foi desenvolvido experimentalmente o método de aplicação de cunha na junção sacroilíaca para aumentar a ventroversão acetabular. O objetivo deste estudo foi aplicar as técnicas de cunha sacroilíaca e OPT em cadáveres e avaliar radiograficamente a eficácia da ventroversão acetabular. Para tal, foram utilizados 10 cadáveres de cães, adultos, com 15-25 kg. Em cada hemipelve direita foi realizada OPT com placas de 20° e 40°. Na hemipelve esquerda foram aplicadas cunhas nas articulações sacroilíacas de 20° e 40°. Avaliações radiográficas em projeções ventrodorsais foram realizadas para mensuração da cobertura acetabular à cabeça femoral nas duas técnicas. De acordo com os dados obtidos pode-se observar que não houve diferença entre a técnica de OPT e o uso de cunha sacroilíaca utilizando implantes de 20° e 40°, mas ocorreu diferença significativa (p<0,05) entre os cães antes e após a aplicação dos implantes de 20° e 40°, e também entre os que receberam implantes de 20° e os de 40°. A aplicação de cunha sacroilíaca produziu resultados semelhantes à OPT, e também se mostrou como de mais fácil aplicação.

Knowledge of the physiology of these animals and serum proteins concentration changes are important for early identification of major diseases which lead to states of hypoproteinemia and hyperproteinemia. The objective was to determine the concentration of total protein and serum protein electrophoresis profile of Crotalus durissus terrificus (rattlesnake) in captivity. Blood samples were taken from the ventral coccygeal vein of 21 adult and healthy snakes divided into groups: Group 1 with 12 males, weighing in average 588.89±193.55g, and Group 2 with nine females, weighing in average 708.33±194.04g. The total serum concentration of protein was determined by the method of refractometry and agarose gel electrophoresis. The total protein values in the serum for females was 4.82±0.72, for males 4.51±0.50 and males and females 4.64±0.61, identified by four fractions (g/dL): albumin, a, b and g-globulin. Additionally the albumin/globulin ratio was calculated. The female snakes showed higher values for the variables, albumin and the albumin/globulin (AG) differed significantly (P<0.05) from the group of male snakes, but there was no clinical significance.

Blood samples were taken from the ventral coccygeal vein of 21 adult and healthy snakes divided into groups: Group 1 with 12 males, weighing in average 588.89±193.55g, and Group 2 with nine females, weighing in average 708.33±194.04g. The total serum concentration of protein was determined by the method of refractometry and agarose gel electrophoresis. The total protein values in the serum for females was 4.82±0.72, for males 4.51±0.50 and males and females 4.64±0.61, identified by four fractions (g/dL): albumin, a, b and g-globulin. Additionally the albumin/globulin ratio was calculated. The female snakes showed higher values for the variables, albumin and the albumin/globulin (AG) differed significantly (P<0.05) from the group of male snakes, but there was no clinical significance.


#359 - Evaluation of left ventricular diastolic echocardiographic parameters in healthy dogs by pulsed-wave Doppler, p.291-294

Abstract in English:

ABSTRACT.- Pereira G.G., Petrus L.C., Santos A.L.F., Yamaki F.L. & Larsson M.H.M.A. 2009. Evaluation of left ventricular diastolic echocardiographic parameters in healthy dogs by pulsed-wave Doppler. Pesquisa Veterinária Brasileira 29(4):291-294. Departamento de Clínica Médica, Faculdade de Medicina Veterinária e Zootecnia, Universidade de São Paulo, Av. Prof. Orlando Marques de Paiva 87, São Paulo, SP 05508-900, Brazil. E-mail: ggpereira2002@yahoo.com.br Left ventricular diastolic dysfunction plays an important role on heart failure progression. In order to obtain additional reference values of left ventricular diastolic parameters and investigate influence of common variables, peak E wave (peak E), peak A wave (peak A), E/A ratio (E/A), E wave deceleration time (EDT) and isovolumic relaxation time (IRVT) were studied in 40 clinically healthy dogs, by pulsed wave Doppler. The following values were obtained: peak E = 0.747 ± 0.117 m/s, peak A = 0.487 ± 0.062 m/s, E/A = 1.533 ± 0.198, EDT = 88.7 ± 9.2 ms and IRVT = 0.080 ± 0.009 s. Some parameters were influenced by heart rate (peak E, peak A and IRVT), by age (peak A and E/A) and by body weight (TRIV). Gender influence was absent. Values obtained can be used as reference for canine specimens but its interpretation should consider on the influence of related variables.

Prof. Dr. Orlando Marques de Paiva 87, São Paulo, SP 05508-900, Brazil. E-mail: danielcgarcia@hotmail.com “Inflow Occlusion” technique can be used in heart surgeries when heart is required to be opened just for few minutes, to allow quick repairs. However, circulatory arrest, event occasioned by this technique, may produce serious metabolic and neurological consequences to the patient. In this study, 12 mongrel dogs were used, divided into two groups, A and B, which were submitted to 7 and 8 minutes of total circulatory arrest, respectively, using “Inflow Occlusion” technique. Normothermia was tried during surgical procedures. Clinical and behavior evaluation were performed after surgery to both groups, and biochemical data were collected to compare pre and post-operatory moments. There were two transoperatory deaths in Group B. Transitory clinical problems were observed in group A until moment M7 (48 hours after surgery), and in Group B these problems were more intense and seen even after M7; and permanent blindness in one animal of Group B was present during all follow up period. Despite all alterations found during the study, it might be safe to use “Inflow Occlusion” technique for periods up to 7 minutes, however, it is contra-indicated for longer periods.
