Aim: To describe the bacterial and fungal organisms in otitis externa patients without other risk factors for fungal infections. Study design: Cross sectional cohort descriptive study. Materials and Methods: Ear swabs were obtained from 362 patients aged 1 to 55 years old with clinically diagnosed otitis externa in Erzurum, Turkey, between January 2006 and April 2007, and cultured for aerobic and anaerobic bacteria and fungi, using EMB, 5% sheep's blood, chocolate agar, anaerobic blood agar plate, thioglycollate broth and sabaroud agar using standard microbiological technique to diagnose isolates. Results: 219 cultures were positive and a total of 267 isolates were obtained. Of the isolates, 68.16% (n: 182) were aerobic or facultative bacteria, 1.12 % (3) were anaerobic bacteria, 30.71 % (82) were fungi and 17.5 % (38) were polymicrobial infections. Conclusion: Fungal organisms especially Candida species may be isolated from ears of otitis externa patients without fungal infection risk factors such as ear self-cleaning, local antimicrobial, antifungal or corticosteroid drops or systemic antimicrobial or antifungal agents within the preceding week. Bacterial and fungal cultures may be recommended, and anti-fungal agents may be added, to treatment regimens in patients with otitis externa.

Objective: The aim of the study is researching the incidence of group A beta hemolytic streptococci (GABHS) in upper respiratory tract infections in Turkey. Study design: This is a descriptive study. Subject and Methods: Totally, 3964 throat swabs obtained from patients with upper respiratory tract infections were cultured for isolation of GABHS in Corlu Military Hospital, Department of Microbiology, between April 2002 and April 2004. Standard microbiological techniques were used in the screening. Results: In this study, GABHS were isolated from 230 (5.80 %) of 3964 patients. The rate of isolation was 79 (5.65 %)/914 in 2002 year, 103 (5.55 %)/1857 in 2003 year, and 48 (6.77 %)/709 in 2004 year. The rate of isolation was 50 (5.47 %)/914 in the spring, 21 (3.21 %)/642 in the summer, 49 (5.81 %)/844 in the autumn, and 110 (7.03 %)/1564 in the winter. Conclusion: We found that the overall incidence of GABHS in respiratory tract infections (5,80 %) was lower than other studies and the incidence was the highest in the winter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
