Abstract
Attachment of bacterial biofilm to the surfaces of farm, fomites and equipments remains chance transmission of infection poultry and human through food chain. Formation of biofilm causes spoilage of poultry products during processing of eggs, meat and distribution. Biofilm may cause many bacterial species in biofilm society. The formation of biofilm deteriorates food quality, water supply system, drugs resistance, and reduces the efficacy of equipments, spread disease and lingering of disease course. Common bacteria cause biofilm in poultry farm and food industries are Salmonella sp., Staphylococcus spp., Listeria monocytogenes, Escherichia coli, Klebsiella pneumonae, Campylobacter jejuni, Streptococcus agalactiae. Formation of biofilm is under stress and regulated by several genes of bacterial. There are several methods of diagnosis of biofilm such as Roll plate method, tube method, microtitre assay, PCR assay, mass spectrometry method and Biological assay of Biofilm. Therapeutic elimination of biofilms for smooth production of poultry is chemical and environmental modifications. Water may be treated with several means, both chemical and physical ways. Food-contaminated biofilm-related treatment is done applying quaternary ammonium compounds, aldehydes, phenolics, alkyl amines, chlorine dioxide, etc. Veterinary medical therapy against biofilms is use of antibiotics with ultrasound, low electric current, phage therapy, nanodrug delivery system, antimicrobial peptides, antiadhesin, antimatrix and chelating substances.
