Antiobiotic resistance

Comparison of Antibiotic Resistance and Virulence Factors in Pigmented and Non-pigmented Pseudomonas aeruginosa

The study found that pigment production was significantly associated with multi-drug resistance, presence of virulence-associated genes, and expression of some important virulence factors. The authors conclude that since pigment production is easy to determine, this might be a good starting point to identify the virulence status of an isolate.


Objective: Pseudomonas aeruginosa produces multiple virulence factors that have been implicated in pathogenesis and quorum sensing. The aim of this study was to determine differences in the virulence factors of pigmented and non-pigmented P aeruginosa isolates.
