NOYA CABANA, Andrés et al. Incidence and drug-resistance of Staphylococcus spp strains isolated from conjunctival swabs. Rev Cubana Oftalmol [online]. 2010, vol.23, suppl.1, pp. 568-579. ISSN 1561-3070.

OBJECTIVE: To determine the incidence of Staphylococcus strains isolated from conjunctival swaps and their resistance to several antimicrobial agents. METHODS: A retrospective, descriptive and observational study was performed to review 3554 conjunctival swabs from patients who went to "Ramón Pando Ferrer" Institute of Ophthalmology in the period from January 2002 to December 2009 due to a diagnosis of external ocular infection. RESULTS: From the total of conjunctival swabs, 874 Staphylococcus aureus strains (47.5 %) and 965 (52.4 %) negative Staphylococcus spp. coagulasa strains were isolated, being pathogenecity test positive in 52.4 %. In 69 swabs, the cultures presented mixed etiology with two different bacteria accounting for 3.7 %. Resistance percentages of Staphylococcus strains were estimated. CONCLUSION: The incidence of Staphylococcus species in eye infections was high and the drug resistance for Staphylococcus aureus and Staphylococcus spp. coagulasa negative to Ciprofloxacin and Amikacyn was lower. The greatest drug resistance of S. aureus strains corresponded to erythromycin and tetracycline whereas Staphylococcus spp coagulasa negative were more resistant to tetracycline.
