Resumen
La mastitis bovina en sus formas clínica y subclínica representan uno de los mayores problemas de la industria lechera. En este trabajo se realizó elanálisis de la estructura genética de la población de S. aureus asociado a mastitis bovina en tres regiones geográficas representadas por los municipiosde Tarímbaro en Michoacán, Yuriria en Guanajuato y Toluca en el Estado de México. Se utilizó el análisis de secuencias multilocus (MLST) delos aislados para establecer las relaciones filogenéticas y de dispersión genética de la población. Se encontraron dos linajes genéticos prevalentes,asociados al Complejo Clonal (CC) 97 y al CC126. También se encontraron genotipos con Secuencia-Tipo (ST) 8 en bovinos, cuando este genotipose ha descrito para clonas pandémicas de infecciones adquiridas en la comunidad. Además la presencia de genotipos típicos de bovino en humanosy de genotipos típicos de humano en bovinos sugieren el potencial zoonótico de los mismos.
