Descrevem-se os achados clínicos e patológicos atribuídos à infecção maciça por trematódeos pancreáticos do gênero Eurytrema (Loos, 1907) em uma novilha da raça Jersey, procedente do município de Seara, região oeste do estado de Santa Catarina, Brasil. O animal de dois anos de idade apresentava desenvolvimento insuficiente, emagrecimento crônico, caquexia, decúbito prolongado e anemia, sendo submetido à eutanásia in extremis. Na necropsia observou-se aumento de volume do pâncreas, que estava esbranquiçado, crepitante, com a superfície de corte irregular, onde foram visualizados inúmeros trematódeos emergindo ativamente do órgão. Histologicamente havia pancreatite intersticial crônica. O parasito foi identificado como Eurytrema coelomaticum (Giard & Billet, 1882). Trata-se do primeiro registro de euritrematose clínica em bovino no estado de Santa Catarina.
Lagochilascariasis, a parasitic disease little known in Brazil, is caused by an ascarid nematode that has a peculiar life cycle, with a predilection site for the cervical region in the final hosts: humans, cats and dogs. We aimed to record the occurrence of Lagochilascaris minor in domestic cats from rural areas in the Municipality of Pelotas, Rio Grande do Sul State, Brazil, with reports of clinical signs and the treatment applied.
Rattus rattus tiene hábitos sinantrópicos que lo convierten en el roedor importante para la difusión de parasitos zoonóticos. Treinta individuos fueron capturados y someterse a necropsia con el objetivo de conocer la fauna de helmintos de R. rattus. Se encontraron tres espécies, dos nematodos (Aspiculuris tetraptera y Syphacia obvelata) y uno cestodo (Hymenolepis diminuta). El área rural mostró mayor diversidad de helmintos.
The aim of this study was to evaluate the presence of helminthes parasitizing hares (Lepus europaeus) in southern Brazil. The intestinal tracts of seven hares were opened and the contents were sieved. Among the seven animals in the study, Trichostrongylus retortaeformis parasitized six (85.7%). This study will be expanded and more animals captured to evaluate the occurrence of other helminthes and to assess whether the high prevalence of T. retortaeformis is accurate, as well as to assess the abundance and intensity of parasites. To our knowledge, this is the first record of T.retortaeformis parasitizing L. europaeus in southern Brazil.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
