CASTELLAR M, Anaís et al. DETECTION OF PATHOGENIC Leptospira spp IN HOUSE MOUSE (Mus musculus) KIDNEY TISSUE IN SINCELEJO, COLOMBIA. Biosalud [online]. 2016, vol.15, n.1, pp.41-49. ISSN 1657-9550.  https://doi.org/10.17151/biosa.2016.15.1.5.

Leptospirosis is a zoonotic disease of worldwide distribution with more frequency in tropical countries. Some rodents and among them the Mus musculus or house mouse are asymptomatic chronic carriers of pathogenic Leptospira spp because they have them in their kidneys and spread it to the environment through the urine. This study aimed to detect Leptospira spp molecularly in kidneys removed from M. musculus in the municipality of Sincelejo (Sucre, Colombia). The capture of rodents was conducted in the urban area of the city: intra and peridomiciliar Sherman® traps were installed in the second quarter of 2010 and the first quarter of 2011 for 14 to 15 hours. During the necropsy the kidneys of individuals were removed for DNA extraction and PCR analysis for the amplification of the 423 pb gene segment between positions 270 and 692 of the coding region LipL32. A total of 154 individuals were captured, of which five were positive for pathogenic Leptospira spp. The correlation analysis showed that mice are mostly positive in commune 2, followed by commune 4 in the municipality. The study suggests that basic sanitation establishes favorable environments for the epidemiological process of the bacteria and the circulation of pathogenic Leptospira spp. in M. musculus is demonstrated in the municipality of Sincelejo. It is inferred that rodent infestation in the studied area is a potential source for the transmission of pathogenic Leptospira spp. to human beings, which is susceptible to all pathogenic species of the genus.
