Effects of some locally isolated Lactobacillus species on general growth, muscular mass and bone development in mice

Probiotics are dietary supplements which contain live microorganisms, mostly different bacterial species that inhabit gut of host and ultimately benefit that host. The current investigation was done to explore the growth-promoting effects of four locally isolated probiotics strains L. paracasei, L. paracaseii, L. delbrueckii and L. rhamnosus. In this regard, 108 colony-forming units (CFU) were administered to the mice of experimental groups for 30 days. Upon administering probiotics, it was observed that the Lactobacilli species had a positive impact on body weight. The group that received L. rhamnosus exhibited the most significant increase, with a 76.53 % improvement over the control group (P
