Abstract

The virulence factor genotypes of a large cohort of clinical, nosocomial environment and community environment isolates (184 in total) of from Tasmania, Australia, were determined by PCR. The virulence factor genotype of the majority of isolates was highly conserved, with the exception of the virulence gene , which demonstrated low prevalence (33 isolates; 18 %) in the population tested. Isolates collected from the environment of intensive therapy wards (intensive care unit and neurosurgical units) of the major tertiary referral hospital in Tasmania were found to be more likely (<0.001 and <0.05, respectively) to possess the virulence factor gene than all other isolates. Adult cystic fibrosis isolates showed a decreased prevalence of the gene (<0.01) when compared to other clinical isolates (<0.01), which may indicate decreased virulence. No specific virulence factor genotype was associated with the cystic fibrosis epidemic strains tested.
