Prevalencia de Leptospira spp. en bovinos de fincas de la parroquia Calderón, Manabí, Ecuador

In this study, the prevalence of Leptospira spp. in cattle from Calderón Parish, Manabí, Ecuador, was evaluated based on data reported by the Agency for Phytosanitary and Zoosanitary Regulation and Control in 2023, as part of the information gathered during the Foot-and-Mouth Disease vaccination campaign. The population consisted of 3,661 cattle from 129 farms. Convenience sampling was used due to limiting conditions, such as the availability of the Invitrogen™ PureLink™ Microbiome DNA Purification Kit and the willingness of farmers to participate in the study. 75 cattle from 26 farms were selected, supported by collaborative work between INSPI and ESPAM MFL. Initially, a survey was conducted with farm owners using the Epicollect5 platform. Blood samples were then collected and analyzed at the National Institute of Public Health Research (INSPI) using the mentioned kit to diagnose the disease. The results showed an absence of leptospirosis prevalence during the evaluated period. However, risk factors were identified in the area, with the most significant being the reuse of needles for administering medications, vaccination practices, water supply for animals, rodent control, body condition, abortions, and sex. This finding underscores the importance of maintaining active epidemiological surveillance, considering leptospirosis is a high-impact zoonosis. Furthermore, it highlights the need to implement preventive measures, primarily vaccination, to reduce the risk of future outbreaks.
