Abstract:
The present invention provides a set of oligonucleotides to screen for the presence of targeted Salmonella serotypes in an enrichment or to characterize presumptive colonies. The set of oligonucleotides includes at least one set of primers and probe for the detection of Salmonella serotype selected from Typhimurium, Enteritidis, Newport, Heidelberg, Infantis, Virchow and Hadar. The set of oligonucleotides may include up to 5 different primer sets and the corresponding probes.
Abstract:
The present invention includes compositions and methods for inhibiting the growth of pathogens in an animal feed comprising the steps of: contacting the animal feed with at least one lactic acid bacterium strain selected from at least one of Lactobacillus salivarius strains L14, L15, L17, L28, or a mixture thereof; or a whey obtained from fermentation of the lactic acid bacterium strain, wherein the at least one lactic acid bacterium strain inhibits the growth of the pathogens, the nosocomial pathogens or the spoilage microorganisms in the animal feed.
