Resumen:
Cattle raising is the most important livestock activity in Mexico,
highlighting the fact that the Country is eight place worldwide in the
production of bovine meat. However, cattle can be affected by
leptospirosis (a bacterial disease caused by 17 species of spirochetes
of the genus Leptospira), which cause reproductive problems that
translate into great economic losses. Additionally, these zoonotic
agents can cause a rapidly evolving febrile condition in humans, which
can be solved after the first week of symptoms or could progress to
develop a severe late-phase manifestations. Despite the great impact of
these agents on the economy and Public Health, epidemiological
surveillance against the infectious disease that cause is not present in
municipal slaughterhouses (MS). Therefore, the aim of this study was to
identify, using serological and molecular methods, the circulating
Leptospira species in three MS in Veracruz State. The frequency of
anti-Leptospira antibodies was 67.5%. Additionally, five sequences were
recovered that were 99% similar to L. interrogans. This work represents
the first national effort for the evaluation of MS as sentinel units,
that allow establishing the diversity of species of the genus Leptospira
that circulate in cattle and establishing intervention measures for
workers risk mitigation, who come into contact with the fluids and
organs of infected animals.
