ABSTRACT The present research evaluated the seroprevalence of anti-zika virus (anti-ZIKV) antibodies by virus neutralization test (VNT) in 529 bovines from Andradina city, São Paulo state, Brazil. The reading was performed in an inverted optical microscope, considering reagents when the antibodies were capable to neutralize the ZIKV. Of the 529 samples, 53 (10.01%) were reagents. The animals were healthy at the time of collection. The samples were collected in February 2018, a favorable period for the multiplication of the vector and the highest risk of disease transmission. None of the animals showed anti-bovine viral diarrhea virus (anti-BVDV) antibodies, ruling out a possible cross-reaction, reinforcing the possible contact of the bovine with the ZIKV. In the herd, 88 pregnant females were evaluated; of these, 12 cows were reactive, with no history of reproductive problems or fetal malformations. This is the first research on the seroprevalence of ZIKV in cattle in Brazil, and studies should continue to evaluate cattle as a possible host of this arbovirus and its possible consequences for unique health and agribusiness.
ABSTRACT: 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.
RESUMO: Entre as doenças que acometem os equídeos, as enfermidades bacterianas assumem um papel importante do ponto de vista sanitário e econômico, destacando-se a leptospirose e a brucelose. O estudo teve como objetivo fornecer informações sobre a ocorrência de anticorpos anti-Leptospira spp. e anti-Brucella abortus em jumentos no estado de São Paulo. Estimou-se que 62,4% (53/85) dos animais apresentavam anticorpos anti-Leptospira spp. Os jumentos estudados não foram sororreagentes contra a Brucella spp.
Barbary sheep (Ammotragus lervia) have the potential to act as hosts of important infectious diseases, particularly zoonoses. Blood samples from 17 Barbary sheep at the Curitiba zoo were collected to evaluate occurrences of anti-Toxoplasma gondii and anti-Neospora caninum antibodies, tested using the indirect immunofluorescence antibody test (IFAT). Anti-T. gondii and anti-N. caninum antibodies were detected in 4/17 (23.5%) and 4/17 (23.5%) samples, respectively. The present study has shown that Barbary sheep at Curitiba zoo were exposed to T. gondii andN. caninum and therefore may act as intermediate hosts, spreading toxoplasmosis and neosporosis within and between species in shared areas.
Aoudads (Ammotragus lervia) têm o potencial para atuar como hospedeiros de importantes doenças infecciosas, em particular as zoonoses. Amostras de sangue de 17 aoudads do zoológico de Curitiba foram coletadas para avaliar ocorrências de anticorpos anti-Toxoplasma gondii e anti-Neospora caninum, testados pela reação de imunofluorescência indireta (RIFI). Anticorpos anti-T. gondii e anti-N. caninum foram detectados em 4/17 (23,5%) e 4/17 (23,5%) das amostras dos aoudads, respectivamente. O presente estudo revelou que os aoudads no zoológico de Curitiba estão expostos a T. gondii eN. caninum e, portanto, podem atuar como hospedeiros intermediários e fatores de difusão da toxoplasmose e da neosporose intra e interespécies em áreas compartilhadas.
