摘要: Pseudomonas aeruginosa strains were isolated from 45 of 370 (12.2%) cockroaches captured in hospitals. By cockroach species, the bacterial 39 181 (21.5%) Periplaneta fuliginosa and 6 183 (3.3%) Blattella germanica, showing a significant difference (p<0.01). Many P. aeruginosa-carrying inhabited locker rooms (66.7%) kitchens (17.8%). In terms serotyping, many isolates typed into groups A, G, B. drug sensitivity tests, showed highest to ciprofloxacin with an MIC90 0.25 microg/ml, followed by 2 microg/ml meropenem, 4 ceftazidime, gentamicin, ofloxacin. contrast, resistant cefotaxime minocycline, accounting for 86.7% all strains. However, there was no multidrug-resistant strain, negative metallo-beta-lactamase gene (IMP-1 VIM-2). These findings suggested that cockroach-derived may contaminate hospital environments, which control disease-carrying insects hospitals is important.
