Abstract

Leptospirosis is one of the most important zoonoses worldwide, considered a neglected emerging disease. In Ecuador, guinea pigs are very important in feeding the population, especially in rural sectors of the inter-Andean region, however there are no investigations that allow us to know the epidemiology of leptospirosis in this species. The aim of this study was to determine the frequency of infection by Leptospira spp. and the associated factors in guinea pigs from the Chantaco and Chuquiribamba parishes of the Loja canton. 175 animals were studied using the microagglutination serological test (MAT) and conventional PCR (hap1 gene) from urine samples. An epidemiological survey was carried out to obtain information on geographic location, rearing system, type of facilities, presence of abortions in the farms, type of food, water supply, presence of other animals around the farms and rodent control; individual data of the animals such as sex and age were recorded. An infection frequency of 6.86% (12/175) was estimated. In serology, the samples were positive for the Pomona, Hardjo, Tarassovi, Sejroe, Bataviae and Canicola serovars. The associated factors (p<0.05) were the geographic location of the property and the presence of cats. This is the first report of leptospirosis in guinea pigs raised for food in Ecuador, with which it is expected that strategies and lines of action will be programmed to control the disease in the species or others that could be affected, including humans.
