Carrying pharyngeal of Streptococcus pyogenes and sensitivity profiles in schoolchild from Cartagena

Abstract

To determine the frequency of carrying pharyngeal of Streptococcus pyogenes and their sensitivity profiles in schoolchildren from Cartagena. Analytical cross-sectional study, the sample was composed by 131 children. Strains of Streptococcus pyogenes were identified using conventional methods. Antibiotic sensitivity was determined the Kirby-Bauer methods. A questionnaire was applied in order to identify risk factors associated.19,8% of children were carriers of bacterium. 26 isolates of Streptococcus pyogenes were obtained. To evaluate the sensitivity were found strains sensible to ceftriaxone and erytrhomycin (84,6% each one). 23,1% (6/26) 0f isolates were resistant to ampicillin. It not was found association between carrying pharyngeal of Streptococcus pyogenes and risk factors (p>0,05). It were found resistant strains to antibiotics considered of first election for therapy of infectious diseases produced by this bacterium.
