Molecular analysis of Pseudomonas aeruginosa isolated from clinical, environmental and cockroach sources by ERIC-PCR

ObjectiveThe objective of this study was to investigate the antibiotic susceptibility, virulence factors and clonal relationship among Pseudomonas aeruginosa isolated from environmental sources, hospitalized patients and the surfaces of cockroaches in the ICUs of four hospitals in Hamadan, west of Iran. A total of 237, 286 and 156 bacterial isolates were collected from clinical...

The same and not the same: heterogeneous functional activation of prostate tumor cells by TLR ligation

Such heterogeneity may be associated with different responsiveness to microenvironment stimuli. In the present study, the effects of lipopolysaccharide (LPS) and lipoteichoic acid (LTA), as well-known mediators of inflammation, on cancerous behavior...
