| Abstract | ||
| The ability of six isolates which belongs to Lactobacillus spp. Involved four isolates to L. plantarum and two isolates to L. acidophilus Were tested to produce bacteriocin and to give a better discouragement effectiveness against eight isolates which belongs to Salmonella spp. Involved five isolates to S. typhimurium and three isolates to S. enteritidis, after filtering the cultures, where the well diffusion assay method was used , So the discouragement effectiveness for Lactobacillus spp. against Salmonella spp. were contracted so the results showed that effects of Lactobacillus spp. was very big on some Salmonella isolates involved S. enteritidis (2) and two isolates to S. typhimurium (4 and 6) where discouragement diameter ranged between under of 10 – 19 mm, while the influence was convergent on bacterial isolates on two isolates from S. enteritidis (1 and 2) and two isolates from S. typhimurium (5 and 6), where discouragement diameter ranged between (2 – 12) mm. But the isolate S. typhimurium (8) was not showed any mentioned sensitivity towards bacteriocin that was produced from the appendant isolates for Lactobacillus spp.The results showed that the isolate L. plantarum (5) was more efficiency On inhibited Salmonella spp. Growth where discouragement diameter ranged between (2 – 12) mlm, while L. plantarum (2) was less efficiency, where confine discouragement on two isolates S. typhimurium (4 and 7) where discouragement diameter (3 and 2) mm respectively. | ||
