Search of antimicrobial lactic acid bacteria from Salmonella-negative dogs.

ABSTRACT:

Background

Salmonellosis is one of the most important food-borne zoonotic disease affecting both animals and humans. The objective of the present study was to identify gastrointestinal (GI) lactic acid bacteria (LAB) of canine-origin from Salmonella-negative dogs' faeces able to inhibit monophasic Salmonella Typhimurium previously isolated from dogs' faeces, in order to be used as a potential probiotic in pet nutrition.

Results

Accordingly, 37 LAB were isolated from Salmonella-negative dogs' faeces and tested against monophasic S. Typhimurium using the spot on lawn method out of which 7 strains showed an inhibition halo higher than 2.5 cm. These 7 strains were also tested with the co-culture method and one showed the greatest inhibition value (p < 0.05). Subsequently, the is
