title: [Reproducible model of a bacterial conjunctivitis].
abstract: To test the efficiency of antimicrobial substances on bacterial conjunctivitis under standardized conditions a reproducible model is needed. As there are no data in the literature concerning this topic we have developed a model of bacterial conjunctivitis in the rabbit eye. Instillation of a suspension of Haemophilus influenzae, Staphylococcus epidermidis or Staphylococcus aureus into the cul-de-sac did not result in any effect. Thus, standardized techniques of conjunctival incision were used additionally. A follow-up was done for a period of 2 weeks (degree of conjunctival hyperemia, microbiology). Radial incision of the conjunctiva with injection of an S. aureus suspension (50 microliters of ATCC 29213; 1.35 x 10(8) cells) was done mimicking a branch injury. This resulted in a purulent conjunctivitis over a period of 1 week and disappeared within 14 days. The swabs were negative on day 7. This is the first model establishing a reproducible purulent conjunctivitis in the rabbit. Using this model antimicrobial substances may be tested under standardized conditions.
