Enterokokların önemli virülens faktörleri ve gıdalarda bulunuşu

Enterokoklar, insan ve çiftlik hayvanlarının doğal bağırsak florasında, toprak, su ve gıdalarda bulunabilen Gram pozitif mikroorganizmalardır. Patojen enterokoklar, sitolizin, agregasyon faktörü, jelatinaz, hyaluronidaz gibi insan sağlığı açısından önemli birçok virülens faktöründen bir veya birkaçına sahiptir. Gıda kaynaklı ve nozokomiyal enterokok infeksiyonlarının gelişiminde; intrinsik ve kazanılmış çoklu antibiyotik direnci önemli rol teşkil etmektedir. Enterokoklar fekal yolla çiğ et ve süt başta olmak üzere taze gıdalara bulaşabilmekte, ayrıca ısıya relatif direncinden dolayı ısı işlemi görmüş gıdalarda da gıda hijyeni açısından önem arz etmektedir.

Important virulence factors of enterococci and presence in foods

Enterococci are ubiquitous Gram-positive bacteria that inhabit intestinal flora of healthy humans and animals, soil, surface water and food. Pathogenic enterococci have one or more of the virulence factors such as cytolysin, aggregation substance, gelatinase, hyaluronidase and etc., which are important for human health. Withal intrinsic and acquired resistance ability to multiple antibiotics, constitutes an important role in the development of nosocomial and foodborne enterococcal infections. Enterococci can be transmitted to fresh foods including raw meat and milk via fecal contamination. As they have relative resistance of heat they can survive in heat-treated foods and for this reason they are important for food hygiene.
