The Effect of lactobacillus spp and bifidobacterium longum on heamatological factors in famale BALB/c mice infected with salmonella typhimurium

Probiotics are live microorganisms that consuming them increase health. It is used in treating and resolving gastrointestinal infections in humans and animals, caused by Salmonella typhimurium. Therefore the aim of this research is to study the effects of probiotic’s mixture on prevention and treatment of female mice BALB/c infected with Salmonella typhimurium ATCC 14028, and to investigate the effects of Probiotics mixture on the blood indices and serum cholesterol level of the infected mice. In this study 18 female mice BALB/c aging 6-8 weeks were chosen and divided into three groups of six: experimental, sham and control. After treating the experimental group with a mixture of probiotic (Lactobacillus acidophilus, Lactobacillus Ramnosus andBifidobacterium Longum) and sham with normal saline orally for 35 days, 1ml of suspension of bacteria (103 CFU / ml) was injected intraperitoneally to the mice in the three groups. After the pre-treatment period, blood samples were takes for testing blood indices. After dissecting the mice and removing spleen, the spleen homogenization was performed and the number of bacteria was counted. According to the results, mixture of probiotic reduced the number of Salmonella typhimurium, spleen and liver indices, reduced liver and spleen weights and increased the number of lymphocyte
