Lacticaseibacillus paracasei strain FAM18126

Lacticaseibacillus paracasei strain FAM18126 is a Gram-positive, rod-shaped bacterium that exhibits a chain-like cell arrangement. As a facultative anaerobe, it can thrive in both aerobic and anaerobic environments. This strain is categorized as mesophilic, with an optimal growth temperature of 30°C, indicating its preference for moderate temperature conditions. L. paracasei strain FAM18126 is non-motile and does not possess flagella. It is free-living, with a single membrane and one replicon, making it a simple yet effective organism in its ecological niche. It has been identified in multiple habitats and is associated with various hosts, including Homo sapiens (humans), Oryctolagus cuniculus (European rabbits), and Panax ginseng (a medicinal plant). One of the notable health effects attributed to L. paracasei strain FAM18126 is its involvement in graft-versus-host disease (GvHD). This condition occurs when donor immune cells attack the recipient's tissues post-transplantation, and the strain's interaction with the human microbiome may influence the severity or management of this condition. Understanding the ecological role and health implications of Lacticaseibacillus paracasei strain FAM18126 can provide insights into its potential applications in probiotics and therapeutic interventions, particularly in relation to immune health and microbial balance in various host organisms.
