Characterization of biofilm formation by clinical isolates of Mycobacterium avium

Mycobacterium avium is an environmental organism encountered in natural and urban water sources as well as soil.M. avium biofilm has recently been identified on sauna walls and in city water pipes and might have a role in the survival of virulent strains in the environment and in the host. To characterize theM. avium biofilm, an in vitromodel was adapted wherein biofilm develops on a PVC surface. Biofilm was detected by staining with crystal violet and visualization by optical microscop
