Identification of the predominance bacterial pathogen of community acquired orofaringitis (OF) at Hospital Geral in Guarulhos,Brazil.

OFs remain the common infections diagnosed in outpatients as well as hospitalized patients, current knowledge on antimicrobial susceptibility pattern is essential for appropriate therapy and the aim of this study was to determine the distribution and antibiotic susceptibility patterns of bacterial strains isolated from patients with community acquired infections (OFs) at Guarulhos as well as identification of ESBL producers in the population of different oral pathogens throught exsudate isolates from symptomatic OFs cases attending to the Hospital Geral at Guarulhos were identified by conventional methods (2006-april 2007) and antimicrobial susceptibility testing was performed by Kirby Bauer’s disc diffusion method. Isolates resistant to third generation cephalosporin were tested for ESBL production by double disk synergy test method and the results points that of the 157 tested sample 71 samples showed growth of pathogens among which the most prevalent were Streptococcus pyogenes (78%)followed by S.aureus (35%) and the majority (70.25%) resistance was observed against ampicillin and co-trimoxazole. Most of the isolates were resistant to 3 or more number of antibiotics, the forty nine percent of isolates were detected to produce ESBL among which 41,21 % were Streptococcus isolates.

This study revealed that Streptococcus pyogenes was the predominant bacterial pathogen of community acquired OFs in Guarulhos,it also demonstrated an increasing resistance to Co-trimoxazole and production of ESBL in OF pathogens in the community.
