Abstract—The aim of the study was to observe the prevalence of various microorganisms from throat swab specimens in patients attending a tertiary care hospital at Chinakakani, Guntur. Throat swab specimens were collected aseptically from 100 patients and cultured on appropriate bacteriological media. Isolates were identified by biochemical tests & antimicrobial susceptibility performed by standard methods. Out of 100 Samples, culture was positive in 25 samples. So Bacterial infection was found in 25% of Pharyngitis. Streptococcus pyogenes was the commonest isolate, followed by Staphylococcus aureus and Candida albicans. Majority of bacteria were Streptococcus pyogenes, Staphylococcus aureus and Candida albicans. In 60% it was mixed infection. The susceptibility patterns varied depending on the drugs, but most of the organisms were susceptible to penicillin, erythromycin and vancomycin. Improved personal hygiene and health education of the masses on how to care for ear, nose and throat will greatly reduce these microbial infections. This study will be useful for control strategies and for predicting pathogen prevalence in throat swabs.
