| dc.description | A partir de material ocular coletado de 46 pacientes submetidos à cirurgia de catarata foram realizados isolamento, identificação e teste de susceptibilidade de microrganismos frente a antimicrobianos, utilizando-se suabes e lentes intraoculares (LIO). Foram obtidos 76 isolados e identificados 7 tipos de microrganismos. Estafilococos coagulase-negativos (CNS) foram os microrganismos mais freqüentemente detectados de suabes (71,4% dos casos), lentes de PMMA (81,3%) e lentes de silicone (77,8%). Isolados de CNS apresentaram elevada resistência à penicilina G, seguida por tetraciclina, cloranfenicol e aminoglicosídeos. No entanto, estes isolados mostraram grande sensibilidade à vancomicina, cefalotina e ofloxacina. Com exceção da penicilina G, os isolados de Staphylococcus aureus foram bastante sensíveis aos agentes antimicrobianos, incluindo a oxacilina. Entre as gramnegativas, Proteus mirabilis foi a bactéria mais freqüente e também se mostrou bastante resistente à tetraciclina e ao cloranfenicol. Os isolados de Enterococcus se mostraram sensíveis à vancomicina. | |
| dc.description | Bacterial isolation, identification and antimicrobial susceptibility tests were carried out in ocular material collected with swab and polimethylmethacrylate (PMMA) or silicone intraocular lenses (IOL) from forty six patients submitted to cataract surgery. Seventy six isolates and seven different microorganisms were identified. Coagulase-negative staphylococci (CNS) were the predominant microorganisms isolated from swabs (71.4% of cases), PMMA lenses (81.3%) and silicon lenses (77.8%). Coagulase-negative staphylococci isolates revealed high resistance to penicillin G followed by tetracycline, chloramphenicol and aminoglicosides. However, these isolates displayed great susceptibility to vancomycin, cephalothin and ofloxacin. Except for penicillin G, Staphylococcus aureus was very sensitive to the antimicrobial agents including oxacillin. Among Gram-negatives, Proteus mirabilis was prevalent and presented high resistance to tetracycline and chloramphenicol. Enterococcus isolates were vancomycin sensitive. | |
