Bacterial etiology of external ocular infections in patients that live together or not with animals.

Etiología bacteriana de infecciones oculares externas

In this investigation 286 patients that presented bacterial conjunctivitis as more frequent diagnostic impression were evaluated. In 286 microbiological cultivations carried out 177 bacterial isolations were obtained, being 73.45% positive Gram flora being the most frequent species S. epidermidis (48.46%), S. aureus (35.38%), S. pneumoniae (4.61%) and Corynebacterium sp. (2.31%). 26.55% corresponded to negative Gram bacilluses of which 74.47% is enterobacterias and 25.53% unfermented micro organisms. In this study was not found significant difference among the coexistence or not with animals and type of isolated microorganism associated to zoonosis.
