Seroprevalence and risk factors for Leptospira spp. in small ruminants of semi-arid zone in northeastern Colombia.

Leptospirosis in small ruminants is an economically important disease that causes important losses by pathologies of the reproductive tract. The present study aimed to estimate the seroprevalence and risk factors associated with Leptospira spp. in small ruminants under traditional husbandry systems.

Cattle seroprevalence and risk factors associated with bovine viral diarrhea in the northeastern of Colombia.

Bovine viral diarrhea (BVD) is one of the most common and economically significant viral infections in cattle. Different risk factors have been associated with viral exposure and transmission, generating endemic regions with different biotype circulations. To find the BVD status in the northeastern region of Colombia, this study aimed to determine the seroprevalence and risk factors associated with the disease in non-vaccinated farms.

in small ruminants in northeastern areas of Colombia: Seroprevalence and risk factors.

Sheep and goats are susceptible to infections with and could play an important role in the transmission of the zoonotic parasite to human. We conducted a cross sectional study to estimate the seroprevalence and to assess the risk factors for seropositivity in small ruminants under traditional husbandry systems. This study was carried out from November 2015 to April 2016 in randomly selected small ruminants ( = 1038) from 48 farms located in Colombia, in the departments of northern Cesar in the north and La Guajira in the south.
