A large number of Brazilian zoos keep many endangered species of deer, however, very few disease surveillance studies have been conducted among captive cervids. Blood samples from 32 Brazilian deer (Blastocerus dichotomus, Mazama nana and Mazama americana) kept in captivity at Bela Vista Biological Sanctuary (Foz do Iguaçu, Brazil) were investigated for 10 ruminant pathogens, with the aims of monitoring deer health status and evaluating any potential zoonotic risk. Deer serum samples were tested for Brucella abortus, Leptospira (23 serovars), Toxoplasma gondii, Neospora caninum, bovine viral diarrhea virus, infectious bovine rhinotracheitis virus, foot-and-mouth disease virus, western equine encephalitis virus, eastern equine encephalitis virus and Venezuelan equine encephalitis virus. Antibodies against T. gondii (15.6%), N. caninum (6.2%) and L. interrogans serogroup Serjoe (3.1%) were detected. The serological results for all other infectious agents were negative. The deer were considered to be clinically healthy and asymptomatic regarding any disease. Compared with studies on free-ranging deer, the prevalences of the same agents tested among the captive deer kept at the Sanctuary were lower, thus indicating good sanitary conditions and high-quality management practices at the zoo.

Among the diseases that affect equines, viral diseases play an important role from a health and economic point of view, especially influenza, viral arteritis, herpes infections and vesicular stomatitis. In the Brazilian literature, there is little or no account of the occurrence of infectious diseases in donkeys. Given the importance of donkeys in different activities and the lack of information on infections that may occur in these animals, the aim of this study was to determine the frequency of anti-equine herpesvirus (EHV), anti-equine arteritis virus (EAV), anti-vesicular stomatitis, and anti-equine influenza (H3N8) antibodies in the serum of 85 donkeys bred in some regions of the state of São Paulo. We found the following antibody frequencies: 50.6% (43/85) antibodies against influenza virus subtype H3N8, 47% (40/85) anti-EHV, and 20% (17/85) anti-EAV. The donkeys were not seropositive for vesicular stomatitis. The results suggested that the agents EHV, EAV, and equine influenza subtype H3N8 circulate among donkeys in some regions of the state of São Paulo, Brazil, reinforcing the importance of establishing a routine diagnosis and epidemiological study of this species.

ResumoDentre as doenças que acometem os equídeos, as enfermidades virais assumem um papel importante do ponto de vista sanitário e econômico, especialmente a influenza, arterite viral, as infecções herpéticas e a estomatite vesicular. Na literatura nacional, existe pouco ou nenhum relato sobre a ocorrência de enfermidades infecciosas nos asininos. Tendo em vista a importância dos asininos para diferentes atividades e a falta de informações sobre as doenças que acometem esses animais, este trabalho teve como objetivo estudar a frequência de anticorpos anti-EHV, antivírus da arterite equina, anti-estomatite vesicular e anti-influenza equina (H3N8) em 85 soros de jumentos criados no estado de São Paulo. Estimou-se que 50,6% apresentavam anticorpos contra o subtipo H3N8 do vírus da influenza; 47% (40/85) apresentavam anticorpos contra o EHV e 20% apresentavam anticorpos contra o vírus da arterite. Os jumentos não foram soro reagentes contra a estomatite vesicular. Os resultados obtidos sugerem que os agentes EHV, vírus da arterite equina e influenza equina subtipo H3N8, circulam entre os jumentos do estado de São Paulo, caracterizando a importância do estabelecimento de uma rotina diagnóstica e estudos epidemiológicos na espécie.

Among the diseases that affect equines, bacterial diseases play an important role from a health and economic point of view, especially leptospirosis and brucellosis. The study aimed to provide information on the occurrence of anti-Leptospira spp. and anti-Brucella abortus antibodies in donkeys of São Paulo state. We found a frequency of 62.4% (53/85) antibodies against Leptospira spp. The donkeys were not seropositive for Brucella spp.

The objective this study was to evaluate the occurrence of small ruminants seropositive for Brucella abortus in Sergipe, Brazil. Samples of sheep (1,200) and goats (675) serum blood was collected from 101 farms of 25 counties of the three mesoregions of the state. The technique of Acidified Buffered Acid stained with Rose Bengal (RB) was used and all samples confirmed a positive result using the 2-Mercaptoethanol technique. Four (0.21%) seropositive animals were diagnosed by technique AAT stained with RB, three sheep’s (0.25%) and a goat (0.15%), were confirmed by the 2ME test. In all the positive properties, the intercropping of small ruminants with cattle was adopted, favoring the contact with the agent. The prevalence of anti-B. abortus antibodies in herds of small ruminants in Sergipe is described for the first time, and is low, however, it is important to identify seropositive animals to be discarded due to their zoonotic potential.
