Cysticercosis represents an important public health problem that can cause significant economic losses to the beef industry. The present study aimed to determine the prevalence rate of cysticercosis in cattle and estimate the economic losses to producers associated with this parasitic disease. Data were collected from the official sanitary inspection service of a slaughterhouse located in the city of Uberlândia, Minas Gerais, southeast Brazil, from 2009 to 2016. A total of 358,383 cattle from 46 cities in Minas Gerais, Brazil, were slaughtered, of which 4,243 were infected with cysticercosis (1.18%). A total of 5,194 cysticerci were detected in these carcasses, of which 4,548 (87.56%) were alive and 646 (12.44%) were calcified. Most of the cysticerci were located in the masseter and pterygoid masticatory muscles (72.41%). As to the classification of cysticercosis according to the degree of infection of organs and/or parts affected, mild infection was the most frequently observed (92.36%). Rural producers had a total of R$ 1,755,204.20 (US$ 537,526.80) of economic losses due to bovine cysticercosis during the time span of eight years covered by this retrospective study. The importance of the sanitary inspection of meat in the control of this major zoonotic diseases is emphasized.

RESUMO Os métodos moleculares de detecção rápida e eficaz de lotes de aves infectados por bactérias como Salmonella sp. Campylobacter sp. e Listeria monocytogenes são importantes para reduzir a frequência da transmissão destes patógenos entre os lotes de aves e aos consumidores de produtos de origem animal. Recentemente, as técnicas de biologia molecular, em especial a reação em cadeia polimerase, que permite a amplificação específica de segmentos de DNA, têm possibilitado novos rumos na identificação de bactérias supracitadas, reduzindo o tempo de cultivo e ampliando a confiabilidade das provas diagnósticas. A utilização da biologia molecular por laboratórios de diagnóstico humano e animal, assim como em programas de controle de qualidade de alimentos e produtos de origem animal, já é realidade e tende a se expandir rapidamente. O objetivo deste artigo é fazer uma breve revisão dos testes diagnósticos convencionais e moleculares para identificar Campylobacter sp., Salmonella sp. e Listeria monocytogenes. Concluindo, o diagnóstico molecular é um campo em avanço científico e tecnológico, no qual novas técnicas moleculares estão em desenvolvimento para o diagnóstico de bactérias em alimentos.

Neste trabalho objetivou-se relatar o uso de permanganato de potássio e azul de metileno (cloreto de metiltionina) no tratamento de lesão cutânea da pirarara exposta para visitação pública. Pirarara, nome comum para espécie Phractocephalus hemioliopterus, é originária da bacia amazônica e bastante valorizada na aqüicultura pelo fácil manejo, adaptação ao cativeiro e pela bela fisionomia e coloração, porém muito susceptível à infestação por ectoparasitas acarretando em mortalidades tanto no aspecto produtivo como no mercado pet. A adesão de anelídeos na pele desta espécie alocada no aquário público da cidade de Uberlândia, Minas Gerais, Brasil, levou à lesão cutânea grave e infecção secundária por fungos e bactérias necessitando de tratamento medicamentoso. O diagnóstico foi feito através de achados macroscópicos e das características fisiológicas e comportamentais do animal e o tratamento durou trinta e quatro dias. Após identificação da lesão, os ectoparasitas foram retirados manualmente e o peixe foi conduzido ao tanque escavado isolando-o de outros animais e sem acesso aos visitantes. Adotou-se, respectivamente, o tratamento tópico de 10 gramas e 2 gramas por metro cúbico de permanganato de potássio e azul de metileno até o desaparecimento total da ferida e cura do animal. Com recuperação clínica, o peixe retornou ao aquário exposto à visitação.

The considerable economic impact caused by the occurrence of uterine diseases in dairy cows intensifies research on the prevalence of uterine secretions and the ideal methods of diagnosis. The objective of this study was to determine the prevalence of endometritis and cervicitis in 453 pieces of the reproductive apparatus of dairy cows destined to slaughter and to verify the concordance between the presence of secretion in the cervical and uterine regions and the confirmation in cytology and histology. In addition, to evaluate the correlation between endometritis and cervicitis. Through the determination of the sensitivity and specificity and the Kappa index, it was verified that the agreement between the presence of secretion (uterine / cervical) and the endometrial and cervical cytobrush technique was low between the two diagnostic methods, it was also verified that Histology consists of a good diagnostic method, but more invasive and higher cost. Regarding the association of cervicitis and endometritis, low concordance was observed. Therefore, it is concluded that the diagnosis of uterine diseases performed only by the presence of secretions is flawed, and a cytological and, if possible, histological examination is necessary, helping to reduce reproductive problems and increase the reproductive performance of dairy cows.
