Resumen
The purpose of this study was to determine the
epidemiology of leptospirosis in rural areas of Ciénaga de
Oro, Córdoba, Colombia, a convenience sampling was carried
out on 13 farms. The sample size was 325 reproductive age
cows, 11 canine samples, and 20 humans. The samples were
subjected to MAT analysis with 11 serogroups of Leptospira
interrogans sensu lato. Once the MAT results were received,
urine samples were collected from 78 cows, along with 39
water samples, for bacteriological cultures and PCR for the
16S rRNA gene in L. interrogans sensu lato. Positive PCR
samples were sequenced to determine the possible genome
species. The leptospirosis seroprevalence was 74.5% in the
cattle, 70.0% in the dogs, and 45.5% in the humans.
Although isolation was not achieved, L. interrogans sensu
lato was detected by PCR in three urine samples and in a
sample of wastewater. The sequencing confirmed the circulation
of pathogenic species. The high prevalence of antibodies
for L. interrogans sensu lato and the molecular evidence led to
the inference that the rural areas of Ciénaga de Oro are endemic
and that cattle can act as renal carriers and contaminate
water sources, which increases the risk of contracting
leptospirosis.
