MOLECULAR IDENTIFICATION OF ROSEOMONAS MUCOSA AND DETERMINATION THE SOME OF ITS VIRULENCE FACTORS

This study was aimed to characterize Roseomonas mucosa isolate using molecular genetics and determination some bacterial virulence factors such as capsular, biofilm formation antimicrobial susceptibility. By Polymerase chain reaction (PCR) technique, the characterization of R. done by 16S rRNA gene sequence phylogenetic analysis. Antimicrobial susceptibility test carried out Kirby-Bauer disk diffusion method. Capsular detection examined nigrosin pigment. While Congo red agar microtiter plate enzyme-linked immunosorbent assay (ELISA) reader methods are used determined capability produce a biofilm. The shows bacterium that isolated from catheter dialysis Iraqi patient is belong mucosa. strain showed resistant Amoxicillin, methicillin, carbapenemes, bacitracin Sulfamethoxazole. it susceptible tobramycin, levofloxacin, colisitin sulphate, doxycycline, azithromycin cephalexin. results show encapsulated. Furthermore, has ability form weak findings suggest in spite this genus seems have an overall little pathogenic potential for humans, sp. particular, may be substantial pathogens individuals with underlying medical complications.
