Article Synopsis
  • The study investigated how yeast cell wall prebiotics and probiotics affect gut health, immune response, and growth in weaned piglets as alternatives to antibiotic growth promoters.
  • Results showed that the feed conversion ratio (FCR) was significantly better in piglets on the yeast treatments compared to those receiving antibiotics, with the best performers being those on the yeast cell wall diet alone.
  • The introduction of probiotics appeared to enhance levels of certain immune markers, while also altering gut microbiota composition, particularly increasing the presence of beneficial Lactobacillus species in the probiotic groups.

Leprosy is a chronic bacterial infection mainly caused by Mycobacterium leprae that primarily affects skin and peripheral nerves. Due to its ability to absorb carbon from the host cell, the bacillus became dependent on energy production, mainly through oxidative phosphorylation. In fact, variations in genes of Complex I of oxidative phosphorylation encoded by mtDNA have been associated with several diseases in humans, including bacterial infections, which are possible influencers in the host response to leprosy.

Bacterial cell wall formation is essential for cellular survival and morphogenesis. The peptidoglycan (PG), a heteropolymer that surrounds the bacterial membrane, is a key component of the cell wall, and its multistep biosynthetic process is an attractive antibacterial development target. Penicillin-binding proteins (PBPs) are responsible for cross-linking PG stem peptides, and their central role in bacterial cell wall synthesis has made them the target of successful antibiotics, including β-lactams, that have been used worldwide for decades.
