Pseudomonas aeruginosa
is a Gram negative bacilli isolated from different environments mainly from hospitals being considered a nosocomial pathogen. The pathogenic factors synthesized by this bacteria are rarely investigated, thus we analyzed by SDS PAGE the exoproducts of
P. aeruginosa isolates from different clinical conditions in patients from the Hospital Vargas, Caracas, Venezuela. We found variability in the number of protein bands as well as in their molecular weights from different isolates. The highest number of protein bands was found in the bronchial isolate while the lowest number in the isolate from peritoneal fluid. A band of 35,000 D appeared in 86% of the strains, a band of 105,000 D was only evident in the isolated from urinary tract. We conclude that
P. aeruginosa synthesizes
in vitro differents factors that could be related to the clinical localization of the infection.
