Epidemiological Significance of the Colonization of Streptococcus Agalactiae in the Anorectum and Endocervix of Non-Parturients in Jos, Nigeria

Knowledge of Group B Streptococcus (GBS) carriage and infections in Africa is very scanty but few cases have been reported in Nigeria in particular. Streptococcus agalactiae has been reported to cause infections and diseases in non-parturients and adults ranging from bacteremia, osteomylitis, arthritis, and endocarditis to breast abscess among others, hence the necessity for this study. Fifty six non-pregnant women of different age groups and social status were screened for GBS in Plateau State Specialist Hospital using the Christie, Atkins and Munch-Petersen (CAMP) and hippurate hydrolysis tests. Two (3.6 %) of the 56 women were positive for GBS. The 2 isolates were all from the anorectum. The endocervix yielded no culture. The antibiogram showed that ampicillin is the drug of choice with all isolates (100%) sensitive to the drug. No statistically significant relationship was observed between the clinical and epidemiological characteristics of the patients and GBS carriage (P>0.05). This survey shows a much lower carriage proportion than that reported in Ibadan, Nigeria from non-parturients.
