Abstract: | The aims of the present study were: to estimate the seroprevalence of Bluetongue vírus (BTV), bovine alphaherpesvirus 1 (BoHV-1), bovine viral diarrhea virus (BVDV), Brucella abortus and Leptospira spp. in cattle from family farms in North of Minas Gerais; to determine the intercurrence and association among these pathogens; and to assess the possible associated factors to seropositive herds and animals. For this, 476 cows from 46 farms were sampled and evaluated serologically. The seroprevalence in herds and cattle was, respectively, for BTV 100% and 52.0%, for BoHV-1 95.7% and 48.6%, for BVDV 78.3% and 46.1%, for Leptospira spp. 76.1% and 29.1%, and for B. abortus was 0% in herd and cattle. More than 65% of the herds was simultaneously seropositive for BTV, BoHV-1, BVDV and Leptospira spp. Seropositivity for BoHV-1, Leptospira spp. serovar Autumnalis and serovar Hardjoprajitno were associated with abortion, whereas seropositivity for BVDV was associated with BoHV-1. Moreover, association among seropositivity for BVDV, BoHV-1 and Leptospira spp. was also observed. In conclusion, BTV, BoHV-1, BVDV and Leptospira spp. are highly seroprevalent and occurred simultaneously in cattle from family farms in Minas Gerais, indicating the need for the implementation of control measures to avoid economic losses related to these diseases. |

Para isso, 476 vacas de 46 fazendas foram amostradas e avaliadas sorologicamente. A soroprevalência de rebanhos e animais foi, respectivamente, para BTV de 100% e 52.0%, para BoHV 1 de 95.7% e 48.6%, para BVDV de 78.3% e 46.1%, para Leptospira spp. de 76.1% e 29.1% e para B. abortus de 0% para ambos rebanhos e bovinos. Mais de 65% dos rebanhos foram simultaneamente soropositivos para BTV, BoHV-1, BVDV e Leptospira spp. A soropositividade para BoHV-1, Leptospira spp. sorovar Autumnalis e sorovar Hardjoprajitno foram fatores associados com aborto, enquanto soropositividade para BVDV foi fator associado com BoHV-1. Além disso, associação entre a soropositividade para BVDV, BoHV-1 e Leptospira spp. foi observada. Em conclusão, BTV, BVDV, BoHV-1 e Leptospira spp. são altamente soroprevalentes e ocorrem simultaneamente em bovinos da agricultura familiar de Minas Gerais, indicando a necessidade da implementação de medidas de controle para evitar perdas econômicas relacionadas a essas doenças. |
