OBJECTIVES: The aim of this study was to investigate the effects of ophthalmic chloramphenico...
Amongst 100 Streptococcus pneumoniae isolated from clinical cases and nasopharynx of healthy individuals, 60 erythromycin resistant strains were isolated and characterized using MLST, PFGE, transposon analysis and Quellung reaction. Most of the S. pneumoniae erythromycin resistant (80%) were found to be attributable to the ermB-edncoded ribosome methylase activity which differs from the dominan...
Pelvic infection in females often occur as a result of colonization by a variety of bacteria On the vaginal and cervical epithelium.
