Streptococcus agalactiae Wikipedia. 15-11-2012 · Although flies are important vectors of food-borne pathogens, there is little information to accurately assess the food-related health risk of the presence of individual flies, especially in urban areas. This study quantifies the prevalence and the relative risk of food-borne pathogens associated with the body surfaces and guts of individual, Gram‐negative and some Gram‐positive bacteria that are resistant to bacteriocins of lactic acid bacteria (LAB) were subjected to sublethal stresses and treated with nisin and pediocin AcH. Both bacteriocins reduced the viability of cells surviving sublethal stresses..
