Prospective study about the incidence of B lactamase producing bacteriae in otitis media in the population of the emergency room of the University Pediatric Hospital

ABSTRACT

The purpose of the study is to determine the incidence of beta-lactamase producing pathogens causing otitis media (O.M.) in the Emergency Room population of the University Pediatric Hospital. In our first four months of study, 22 patients, between the ages of 6 months to 13 y/o have been evaluated. Middle ear secretion cultures were obtained by tympanocenthesis. The organisms recovered from cultures were S. epidermidis 3(14%), S. pneumoniae 2(9%) H. influenzae 1(5%), mix flora 1(5%) and 13(59%) with no growth. None of these organisms were beta-lactamase producers. Up to 65% of the patients had history of 2 to 5 OM episodes during the last six months. Interesting is the association of bronchial asthma, sinusitis and allergy history with OM. Final study results will be presented in a near future
