title: Microbiological profile of bacterial conjunctivitis in ibadan, Nigeria.
abstract: OBJECTIVE
  In bacterial conjunctivitis, clinical presentations are not diagnostic of the causative agent, therefore, microbiological analysis is mandatory for specific treatment option. This study was undertaken to determine the microbiology profile of bacterial conjunctivitis in our environment.
  
  
  METHODS
  This is a laboratory-based study carried out in the Medical Microbiology Laboratory of University College Hospital, Ibadan, Nigeria. Conjunctival swabs collected from 365 patients with clinically diagnosed conjunctivitis, were analysed by standard bacteriological methods.
  
  
  RESULTS
  Bacterial pathogens were detected in 342 (93.7%) conjunctival samples while 23(6.3%) were sterile. Of the pathogens, 256 (74.9%) were Staphylococcus aureus, 35(10.2%) Coagulase- negative staphylococci, 22 (6.4%) Pseudomonas aeruginosa , 11(3.2%) Escherichia coli, 7(2.1%) Klebsiella species, 5(1.5%) Streptococcus pneumoniae , 4(1.2%) Haemophilus influenzae, 1(0.3%) Proteus mirabilis, and 1(0.3%)Neisseria gonorrhoeae. The highest rate of conjunctivitis 96(26.3%) was found among infants and children (0-10years).Resistance rates to most of the tested antibiotics were high. However, 67% of them were susceptible to ceftriaxone while only 39.2% were susceptible to chloramphenicol.
  
  
  CONCLUSIONS
  This study has recorded high antibiotic resistance in bacterial pathogens of conjunctivitis in this environment; therefore, determining the susceptibility pattern of these pathogens to available antibiotics is crucial to effective management of bacterial conjunctivitis.
