title: Effect of lantibiotic gallidermin against biogenic amine-producing faecal staphylococci from ostriches and pheasants.
abstract: In ostriches and pheasants, there is still limited information relating to staphylococci and their properties. Biogenic amines (BAs) are nitrogenous low-molecular-weight substances with biological functions in animals, plants and microorganisms. In this study, we focused on BA production by targeted faecal staphylococci from ostriches and pheasants and their sensitivity to lantibiotic bacteriocin gallidermin. Gallidermin belongs in a group of polycyclic proteinaceous antimicrobial substances. Thirty-six faecal staphylococci (24 strains from 140 ostriches, 12 from 60 pheasants) comprising different species were tested. Staphylococci from ostriches and pheasants did not produce tryptamine-TRYP, putrescine-PUT, cadaverine-CAD or histamine-HIS. Production of tyramine-TYM, phenylethylamine-PEA was high or very high (100-1000 mg/L). Production of spermine-SPM and spermidine-SPD by staphylococci was very low or low although in the case of staphylococci from pheasants medium production of SPM was found. Because of the risk posed by BAs for consumers, the control of BA-producing bacteria is important from the points of view not only of safety assessment of food-producing animals but also of human health safety. The sensitivity to gallidermin in biogenic amine-producing staphylococci from ostriches and pheasants detected here is the most promising indication for further application of gallidermin for veterinary purposes. The novelty of our study lies in testing the ability of faecal staphylococci from ostriches and pheasants to produce BAs and in their treatment with gallidermin which has so far not been tested in this way.
