Impact of Bacillus licheniformis from yaks following antibiotic therapy in mouse model.

Gut microorganism (GM) is an integral component of the host microbiome and health system. Abuse of antibiotics disrupts the equilibrium of the microbiome, affecting environmental pathogens and host-associated bacteria alike. However, relatively little research on Bacillus licheniformis alleviates the adverse effects of antibiotics. To test the effect of B. licheniformis as a probiotic supplement against the effects of antibiotics, cefalexin was applied, and the recovery from cefalexin-induced jejunal community disorder and intestinal barrier damage was investigated by pathology, real-time PCR

The protective effects of Lactobacillus SNK-6 on growth, organ health, and intestinal function in geese exposed to low concentration Aflatoxin B1.

Aflatoxin B1 (AFB1) is a prevalent mycotoxin present in feed ingredients. In this study, we investigated the effects of Lactobacillus salivarius (L. salivarius) on the Landes geese exposed to AFB1. The 300 one-day-old Landes geese were randomly divided into five groups: The control group received a basic diet, while the other groups were fed a basic diet supplemented with 10 μg/kg AFB1, 10 μg/kg AFB1+ 4*108 cfu/g L. salivarius, 50 μg/kg AFB1, and 50 μg/kg AFB1 + 4*108 cfu/g L. salivarius for 63 d.

Effects of Bacillus coagulans on kidney injury caused by Klebsiella pneumoniae in rabbits.

Klebsiella pneumoniae (KP) is a zoonotic conditionally pathogenic bacterium with a high prevalence of infection. It often induces purulent inflammation of the rabbit lungs, kidneys and other tissues, with high morbidity and mortality. Bacillus coagulans (BC) has the ability to regulate the balance of host intestinal flora and improve host immunity. However, the mechanism of the protective effect of BC on KP-induced kidney injury in rabbits is not clear. To explore this, we randomly divided fifty 35-day-old Eyplus rabbits into five groups: control, KP, low-dose BC (LBC), medium-dose BC (MBC) an

Advances in Microbiome-Based Therapeutics for Dermatological Disorders: Current Insights and Future Directions.

The human skin hosts an estimated 1000 bacterial species that are essential for maintaining skin health. Extensive clinical and preclinical studies have established the significant role of the skin microbiome in dermatological disorders such as atopic dermatitis, psoriasis, diabetic foot ulcers, hidradenitis suppurativa and skin cancers. In these conditions, the skin microbiome is not only altered but, in some cases, implicated in disease pathophysiology.

In the last week of each period, the participants underwent assessments of their subjective mood and measurements of

Microencapsulation protected Lactobacillus viability and its activity in modulating the intestinal microbiota in newly weaned piglets.

Lactobacilli are sensitive to heat, which limits their application as probiotics in livestock production. Lactobacillus rhamnosus LB1 was previously shown to reduce enterotoxigenic Escherichia coli (ETEC) and Salmonella infections in pigs. To investigate its potential in the application, the bacterium was microencapsulated and examined for its survival from feed pelleting and long-term storage as well as its function in modulating pig intestinal microbiota. The in vitro studies showed that freshly microencapsulated Lactobacillus rhamnosus LB1 had viable counts of 9.03 ± 0.049 log10 colony-form…

Fecal transplantation from young zebrafish donors efficiently ameliorates the lipid metabolism disorder of aged recipients exposed to perfluorobutanesulfonate.

Aging is a biological process that is accompanied by the gradual loss of physiological functions. Under the context of ubiquitous and persistent environmental pollution, the elderly will be more vulnerable to the detrimental effects of toxic pollutants than the young. With objectives to explore effective measures to ameliorate the double stress of aging and toxicants, the present study transplanted the feces from young zebrafish donors to aged recipients, which were concurrently exposed to perfluorobutanesulfonate (PFBS), an emerging environmental pollutant of international concern.
