Bacterial biofilm formation, pathogenicity, diagnostics and control: An overview Sawhney R; Berry VIndian J Med Sci 2009[Jul]; 63 (7): 313-21Bacterial biofilms are complex, mono- or poly-microbialn communities adhering to biotic or abiotic surfaces. This adaptation has been implicated as a survival strategy. The formation of biofilms is mediated by mechanical, biochemical and genetical factors. The biofilms enhance the virulence of the pathogen and have their potential role in various infections, such as dental caries, cystic fibrosis, osteonecrosis, urinary tract infection and eye infections. A number of diagnostic techniques, viz., bright-field microscopy, epifluorescence microscopy, scanning electron microscopy, confocal laser scanning microscopy and amplicon length heterogeneity polymerase chain reaction, have been employed for detection of these communities. Researchers have worked on applications of catheter lock solutions, a fish protein coating, acid shock treatment, susceptibility to bacteriophages, etc., for biofilm control. However, we need to rearrange our strategies to have thorough insight and concentrate on priority basis to develop new accurate, precise and rapid diagnostic protocols for detection and evaluation of biofilm. Above all, the strict compliance to these techniques is required for accurate diagnosis and control.|*Biofilms/growth & development[MESH]|Bacterial Adhesion[MESH]|Bacterial Infections/*diagnosis[MESH]|Escherichia coli/pathogenicity/*physiology[MESH]|Fimbriae, Bacterial[MESH]|Humans[MESH]|Pseudomonas/pathogenicity/*physiology[MESH]|Streptococcus/pathogenicity/*physiology[MESH]|Vibrio/pathogenicity/*physiology[MESH] |
