Resumen

PENA, J  y  UFFO, Odalys. GENETIC VARIATION OF Staphylococcus aureus ISOLATED FROM BOVINE MILKIN CUBA, FIRST REPORT. Rev Salud Anim. [online]. 2010, vol.32, n.2, pp.124-127. ISSN 0253-570X.

Staphylococcus aureus is an important and frequent contaminant of raw milk. At present the studies of genetic typing gives important data for controling their dissemination; those are based on genetic variability of the bacterial specie. With the goal of detecting genetic polymorphism typing techniques based on the Polymerase Chain Reaction (PCR) of the genes coa and RNAr were applied in S. aureus isolates from bulk and mastitic milk in Havana. The genetic variability of S. aureus isolates from bovine milk was proven for first time in Cuba and the usefulness of the techniques employed on relatively distant and near geographical areas was demonstrated, as well as the distribution of certain genetic variants as contribution to the molecular epidemiology of this food pathogen.

Palabras clave : Staphylococcus aureus; typing; genetic variability; milk.
