"Seroprevalencia a lesptospira patógenas en caninos domésticos de la ciudad de Portoviejo asociada a las caracterìsticas de los animales reaccionantes al MAT

Abstract

Leptospirosis is a disease caused by a bacterium of the genus Leptospira, which attacks man, domestic and wild animals, it is a pathology classified as an occupational disease, because it is linked to some work such as farmers, slaughterhouse personnel, etc. This bacterium is transmitted mainly through urine, it can also live and reproduce in water from different sources. Exposed canines are a source of infection for man. The genus Leptospira is formed by several species, these in turn, are divided into serogroups and serovars. In the present study, the seroprevalence of pathogenic leptospira was determined in domestic canines from the urban parishes of the city of Portoviejo, during the period from February to November of the year 2019. Three hundred and eighty samples analyzed by the Microscopic Agglutination Test (MAT) were taken from the healthy canines that came to the veterinary centers. The samples was evaluated by diagnostic battery comprised of three serovars of leptospira (Canicola, Hardjo and Tarassovi). The results obtained in the investigation established a prevalence of canine leptospira of 12.6% CI95% (9.3-16.0), of which the serovar Canicola and Hardjo with 6.3% and 5% were more frequent, followed by Tarassovi with 2.6%. Ninety-two percent of the domestic canines sampled in this study, coexist or cohabit with rodents, which are the most likely to convert the MAT against Leptospira. These results suggest exposure leptospira by domestic canines and increase possibility of a risk to the human population of Portoviejo city that in contact with these domestic animals.
