title: Distribution and shifting trends of bacterial keratitis in north China (1989-98).
abstract: OBJECTIVE
  To study the distribution and shifting trends of bacterial keratitis.
  
  
  METHODS
  The data of 2220 corneal isolates from 1 January 1989 to 31 December 1998 were reviewed retrospectively.
  
  
  RESULTS
  Positive culture was recovered in 490 isolates. Gram positive cocci and Gram negative bacilli represented 51% and 39.4%, respectively. Pseudomonas aeruginosa was the most common pathogen (32.2%). A gradual increase in the percentage of Gram positive cocci coupled with a decrease of Gram negative bacilli.
  
  
  CONCLUSIONS
  Pseudomonas aeruginosa and coaculase negative Staphylococcus were the most common pathogens in bacterial keratitis in north China.
