PESQUISA VETERINÁRIA BRASILEIRA

Abstract in English:

The objective was to analyze Sporophila nigricollis and Sporophila caerulescens in terms of body conditions, parasitological, bacteriological, external biometric measurements, and histological analysis of the gastrointestinal tract. We used 115 individuals apprehended from 2020 to 2021 and sent to the Wild Animal Triage Center, Paraíba, Brazil. Concerning weight, S. nigricollis, females and males presented 9.36±1.36g and 9.70±1.39g, and S. caerulescens with 10.5±0.70g and 11.75±1.28g, being the second heaviest. The body condition in 69.62% of S. nigricollis and 62.50% of S. caerulescens was good. In the fecal microbiological examination, 40.25% of S. nigricollis and 40% of S. caerulescens were positive for Isospora sp. Dispharynx sp. was reported for the first time in S. nigricollis and S. caerulescens. In fecal bacteriology, 95.65% of S. nigricollis were identified with Gram-positive cocci and 73.91% with Gram-positive bacilli. Forty-one animals died and were placed under refrigeration for 48 hours; of these, 31.16% of S. nigricollis and 37.50% of S. caerulescens presented inadequate body conditions. 19.51% had gastrointestinal tract engorgement with hemorrhagic points, and 14.63% had hepatic alteration due to yellowish coloration. The study contributes with subsidies for the taxonomic elucidation of the genus Sporophila, in addition to the knowledge of the conditions in which birds are found in sorting centers, once the destination of most of the seized animals is the release, thus, a potential source of pathogens to the natural environment.

O objetivo foi analisar Sporophila nigricollis e Sporophila caerulescens quanto às condições corporais, parasitológicas, bacteriológicas, medidas biométricas externas e análise histológica do trato gastrointestinal. Foram utilizados 115 indivíduos apreendidos entre 2020 e 2021 e encaminhados ao Centro de Triagem de Animais Silvestres, Paraíba, Brasil. Quanto ao peso, S. nigricollis, fêmeas e machos apresentaram, 9,36±1,36g e 9,70±1,39g, e S. caerulescens com 10,5±0,70g e 11,75±1,28g, sendo o segundo mais pesado. A condição corporal em 69,62% de S. nigricollis e 62,50% de S. caerulescens foi boa. No exame microbiológico fecal, 40,25% de S. nigricollis e 40% de S. caerulescens foram positivos para Isospora sp. Dispharynx sp. foi relatada pela primeira vez em S. nigricollis e S. caerulescens. Na bacteriologia fecal, 95,65% dos S. nigricollis foram identificados com cocos Gram-positivos e 73,91% com bacilos Gram-positivos. Quarenta e um animais morreram e foram colocados sob refrigeração por 48 horas; destes, 31,16% de S. nigricollis e 37,50% de S. caerulescens apresentaram condições corporais inadequadas. 19,51% apresentaram ingurgitamento do trato gastrointestinal com pontos hemorrágicos e 14,63% alteração hepática devido à coloração amarelada. O estudo contribui com subsídios para a elucidação taxonômica do gênero Sporophila, além do conhecimento das condições em que as aves se encontram nos centros de triagem, uma vez que a maior parte dos animais apreendidos tem como destino a soltura, sendo assim, uma potencial fonte de patógenos para o ambiente natural.

Abstract in English:

The health monitoring and management systems of coturniculture can be deemed to be in a developmental phase when compared to the poultry industry. Studies regarding taxonomy and parasitic biology in quails (Coturnix japonica) has not been well conducted in Brazil. Most of the information is available from the autopsy case reports, in many ways the parasitic fauna of quails is still unknown. The aim of this study was to conduct a parasitological research in quails in order to contribute to ameliorate this situation. 31 quails, which were 12 months old, were used for the study. Their carcasses and viscera were sent to the Laboratory of Entomology and Tropical Diseases, INPA, Manaus/AM. The circulatory, nervous, respiratory, digestive and reproductive systems of these were studied separately. No blood parasites were found, however, nine species of endoparasites were registered which were distributed among the classes Cestoda, Nematoda and Protozoa. The helminths were distributed in the duodenum, jejunum, ileum, cecum and oviduct. The cecum was found to be the most parasitized organ and contained a wide range of parasites having three species of protozoa and three species of nematodes. Six morphotypes of Eutrichomastix globosus were recorded, and some morphotypes were hyperparasitized with sporangia Sphaerita sp. in the cytoplasm. A large number of parasites were recorded in this study, as well as the protozoan Blastocystis hominis was first being observed for quail.

Abstract in Portuguese:

A coturnicultura conta com um monitoramento sanitário e sistemas de manejo ainda em desenvolvimento quando comparado à avicultura industrial. Pesquisas de taxonomia e biologia parasitárias em codornas (Coturnix japonica) são pouco realizadas no Brasil, sendo a maioria das informações disponíveis referentes a relatos de caso em achados de necropsia, portanto, em muitos aspectos a fauna parasitária de codornas é ainda desconhecida. Este trabalho teve por objetivo realizar uma pesquisa parasitológica em codornas em fim de postura. Para pesquisa foram disponibilizadas 31 codornas com idades de 12 meses. As carcaças e suas vísceras foram encaminhadas ao Laboratório de Entomologia e Doenças Tropicais INPA, Manaus/AM. Foram estudados separadamente os sistemas circulatórios, nervoso, respiratório, digestivo e reprodutivo. Das 31 codornas examinadas nenhuma apresentou hemoparasitos, contudo, foram registradas nove espécies de endoparasitos distribuídas entre as classes Cestoda, Nematoda e protozoários. Os helmintos distribuíam-se pelo duodeno, jejuno, íleo, cecos e oviduto. O ceco foi o órgão mais parasitado e com maior diversidade de parasitas, sendo três espécies de protozoários e três de nematóides. Foram registrados seis morfotipos de Eutrichomastix globosus, sendo que, alguns morfótipos estavam hiperparasitados com esporângio Sphaerita sp. no citoplasma. Uma grande variedade de parasitos foi registrada nesta pesquisa, bem como, o protozoário Blastocystis hominis pela primeira vez sendo descrito para codornas.

Livestock, pets and wildlife may benefit from products in nanoscale, such as vaccines, target recombinant proteins, or new drug candidates. Thus, we want to give some food for thought to drive scientific programs into nanotechnology, creating a safer environment to animals and humans.

E-mail: headleysa@cesumar.br A retrospective study of cattle slaughtered in northern Paraná during 2000 was performed to determine the prevalence and geographical distribution of bovine eurytrematosis (BE), as identified by the Federal Inspection Service (SIF). The cattle was from different regions of the State of Paraná; all regions had cattle parasitized by Eurytrema spp. BE was identified in 12.1% (12,534/103,411) of the total number of cattle inspected. Prevalence of animals parasitized by Eurytrema spp varied from 8.3% (Region G, São João do Caiuá, 1,069/12,914) to 40.5% (Region R, Ponta Grossa, 225/555). BE was more prevalent during the month of March (1.6) and markedly reduced during May (-2). A possible seasonal predominance of BE was identified: comparatively fewer cases occurred from April to August, while there was a peak from December to March. The study indicates that bovine eurytrematosis is hypoendemic and occurs in almost all geographical regions of the State of Paraná. The prevalence within this State is variable and may be directly related to factors of the biological cycle of the trematode, particularities of each region, and environmental conditions.
