Bacterial agents associated with bronchopulmonary disorders in eastern Nigeria.

Abstract

Altogether 16,539 sputum specimens were examined microbiologically from 1980 to 1984. Out of these 12,588 were screened by Ziehl-Neelsen's staining technique and 782 were (6.3%) found AFB-positive. Age and sex distributions of the AFB-positive individuals were statistically significant (at 0.05), incidence being most prevalent among those 20 years and above (90.2%) and among males (61.2%). From other specimens cultured, non-AFB organisms were isolated at the following frequencies: coliform-like organisms (15.1%), Streptococcus pneumoniae (55.5%). Klebsiella pneumoniae (5.3%), Streptococcus pyogenes (3.9%), Pseudomonas aeruginosa (3.4%), Haemophilus influenzae (3.0%). Proteus Spp. (0.7%) and Escherichia coli (0.5%). The antibiogram of these isolates revealed a high incidence of multiple antibiotic resistance, a situation that has most probably arisen from the high degree of antibiotic misuse in Nigeria.
