title: The bacteriology of pre-labour rupture of membranes in a Nigerian teaching hospital.
abstract: A prospective case control study that was conducted at the University of Ilorin Teaching Hospital, Ilorin, Nigeria, between 1st January and 31st December 2002. The purpose of this study was to determine the association and the pattern of bacteria/microorganisms in the aetiology of pre-labour premature rupture of membrane (PROM) in this centre. A total of 108 cases of PROM and 98 control cases that presented between 37 completed weeks' and 40 weeks' gestation were analysed. Pathogens were isolated in 48 patients, giving a recovery rate of 44.4%. The common pathogens include Gardnerella vaginalis (29.1%), Candida (23.0%) and Staphylococcus aureus (18.7%). Others were Streps. Pyogenes (16.6%), coagulase negative staphylococcus (CONS) (6.3%) and Klebsiella (6.3%). Only Candida and S. aureus were isolated in the controls. Ofloxacin and azithromycin were 100% active against all the isolated pathogens, while ampicillin was the least active. G. vaginalis was the most sensitive among the isolates while CONS and Klebsiella were the least sensitive. It is evident in this study that some pathogens were associated with PROM and that G. vaginalis was the most common organism and azithromycin was the only antibiotic with 100% sensitivity. We suggest that metronidazole should be added to azithromycin to cover for anaerobes in cases of PROM, where facilities for screening for anaerobes are not available.
