Epidemiological Studies of Potent Environmental Pathogen: Streptococcus pneumoniae
Abstract
A general survey for six months was undertaken for the prevalence of environmental bacterium Streptococcus pneumoniae among the different age groups (3-65 years) including both sexes from various hospitals of Hyderabad city. Laboratory examinations revealed S. pneumoniae as most potent environmental pathogen from the sputum and throat swabs of old aged patients and children respectively. During observations, 39 specimens were growth positive; the biochemistry of isolates revealed that they were coagulase, catalase and oxidase negative, TSI, gel hydrolysis positive and were able to ferment glucose, lactose, maltose, galactose, fructose, sucrose, starch and raffinose. The results of antimicrobial activity showed that pneumococci were resistant to the cefspan, septran, cravit, pipemetic acid, azomax, bacitracin, and penicillin and a clear zone of inhibition was observed on clithromycin, optochin, cefizox, genatamycin, minocyclin, levoflaxacin, and vancomycin. There were intermediate zone of inhibition found on claforan, nalidixic acid, amoxycillin, fosfomycin, fortum, and erythromycin on Mueller Hinton’s agar after 24 hours incubation.
