ABSTRACT

Our investigation indicates there are significant differences in the throat carriage of Staphylococcus aureus resistant to antibiotics (penicillin G, oxacillin, erythromycin, chloramphenicol and vancomycin) in a population in Mexico compared to a similar population in the United States of America (USA). Throat isolates were obtained from 105 healthy adults from the USA (Kennesaw State University, Kennesaw, Georgia, USA) and from 76 healthy adults from Mexico (Xalapa, Veracruz, Mexico.) The data indicate a significantly greater number of resistant isolates of Staphylococcus aureus from the Mexican population (16) than from the USA population (7). Factors that may contribute to these differences were identified from questionnaires completed by each participant. These factors were: 1) a greater percentage of individuals in the Mexico population seek the care of a physician for allergies; 2) a greater percentage of individuals in Mexico have used antibiotics recently; 3) all of the antibiotics used in this investigation are available in Mexico without a prescription from a physician, but none are available in the USA without a prescription from a physician.
