    The possible microbial aethiology of pyoderma among primary school children in the Ashanti region of Ghana
    (1997-06-13) Akoto, Phyllis Victoria
    The possible aetiologic agents of pyoderma were studied among 310 primary school children (aged 5-14 years) drawn from two study areas, rural (Ejisu-Juaben District) and urban (Kumasi district) settings in the Ashanti Region of Ghana. A total of 634 bacterial species was recovered. 3-haemolytic Streptococci gave the highest recovery rate of 45%. Of this, 214 or 74% were identified as Streptococcus pyogenes with the remaining, 25% (or 71) representing Lancefield groups B, C, D and G. This was closely followed up by Staphylococcus aureus 32.6% (207), Staphylococcus epidermidis 10.3% (65), Pseudomonas species 10.3% (65), Proteus mirabilis 2.2% (7) and Escherichia coli 0.3% (2). The isolation of the Pseudomonads particularly, aeruginosa from typical pyoderma lesions was quite thought-provoking due to its innate resistance to most antimicrobial agents. Penicillin G (2mg) was effective only against the isolated species of Streptococci but ineffective against the remaining bacterial species isolated. Gentamycin (10mg), on the other hand, was the only antimicrobial agent with a 100% activity on all isolates including P. aeruginosa. The rest of the antibiotics tested on the bacterial isolates were susceptible to varying degrees.
