ABSTRACT

Objective. The identification of associated bacteria in pharyngoamygdalitis and its response to ampicillin, in children assisted in private medical offices.
Material and methods. 654 samples pharyngeal exudation were obtained in children of nine cities of Mexico, all were obtained in children with pharyngoamygdalitis. The susceptibility of the bacteria associated to the illness was proved in vitro to several antibiotics, among them to ampicillin.
Results. The Streptococcus hemoliticus B (S. pyogenes), group “A” of Lancefield, was identified frequently in 12% of the positive samples and its prevalence in all samples was 47 per thousand. Its sensibility for ampicillin was of 100%.
Conclusion. The response of S. pyogenes to ampicillin is still effective in the treatment of pharyngoamygdalitis. There was to null resistance to this antibiotic.
