Summary: In this study, two strains of Bacillus isolated from camel milk were evaluated and exhibited characteristics of potential probiotics, including acid and bile salts resistance, surface hydrophobicity, auto-aggregation, antioxidant characteristics, and adherence to intestinal cells. These results suggest that Bacillus CM1 and CM2 strains have the potential to be considered as probiotics.

Summary: Research in France since the 1970s has reported cases of Guinea fowl fulminating enteritis, with a coronavirus and picornavirus identified as potential viral pathogens. Deep sequencing revealed the presence of Guinea fowl coronavirus (GfCoV) and a picornavirus (GfPic) in the intestinal content of Guinea fowl with the disease in 2017. Isolation assays in specific pathogen-free chicken eggs failed, but successful isolation of both viruses was achieved in Guinea fowl eggs, indicating the importance of using eggs from the same species where the virus is detected.

Summary: This study demonstrates the potential of Lactobacillus plantarum and Lactobacillus casei as probiotics, showing their ability to regulate intestinal flora, inhibit the proliferation of pathogenic bacteria and viruses, and enhance self-immunity. These strains exhibited strong adaptability, resistance to adverse conditions, and sensitivity to specific pathogens. Additionally, their supernatants were found to inhibit the proliferation of pseudorabies virus (PRV) in cells, and the supplementation of challenged mice with these supernatants delayed the progression of the disease.

Summary: This study investigated the effects of a commercial multi-strain probiotic on the intestinal morphology and microbiota diversity of guinea fowls. The findings showed that probiotic supplementation significantly improved the morphological parameters of the intestine and enriched the presence of beneficial microbiota taxa, indicating a positive impact on gut health.

Summary: This study reveals the unregulated nature of the local probiotic market, with most products failing to meet label claims. Many products contained non-viable cells and showed significant batch-to-batch variation. Half of the products contained antibiotic-resistant strains, posing a risk for the spread of antibiotic resistance and the overall gut health.

Summary: The study revealed that E. coli isolates from chickens and guinea fowl in Gambian homes harbor antimicrobial resistance genes, particularly the ST155 strain showing multidrug resistance to clinically relevant antibiotics, indicating potential pathogenicity. Moreover, close relatedness between Gambian poultry strains and human isolates suggests a risk of transmission.

Summary: The study reported the isolation and evaluation of probiotic capabilities of Lactiplantibacillus plantarum strains from rhizospheric soil, which showed strong hypocholesterolemic potential and resistance to various environmental stresses, as well as exhibited resistance to acidic environment and multiple antibiotics. Further investigation is recommended for its potential as a potent probiotic with hypocholesterolemic biotherapeutic benefits, and the potential of exploring rhizosphere as a niche for isolating microorganisms with probiotic potential.

Summary: This study examined the effects of multi-strain probiotics on the intestinal morphology and glycan composition of guinea fowl, demonstrating significant improvements in morphology and glycoprotein parameters in probiotic-treated group compared to control group. Probiotics have shown to induce region-specific changes in glycoprotein composition of the intestine, promoting gut health in poultry.

Summary: The lactobacilli strains isolated from breast milk showed promising probiotic properties, including presence of specific bacteriocin genes, strong cell adhesion ability, competition with intestinal pathogens, cholesterol-lowering effects, and improvement in inflammatory bowel disease. Further studies could potentially lead to their consideration as probiotic strains.

Summary: This study found that a probiotic strain, Lactobacillus plantarum 14917, has a remarkable inhibitory effect on the pathogenic microorganisms Streptococcus mutans and Candida albicans. It can reduce their growth, alter biofilm structure, and decrease their virulence. This discovery could lead to a new approach for preventing dental caries.

Summary: This study investigated the effects of Lacticaseibacillus paracasei JY062, Lactobacillus gasseri JM1, and their combination on mice with GI motility disorder induced by loperamide. The probiotic combination was found to alleviate GI motility disorder better by increasing the secretion of excitatory GI regulators and decreasing the secretion of inhibitory GI regulators, except vasoactive intestinal peptide. The intervention also increased the number of interstitial cells of Cajal, the expression of SCF/c-kit protein, the abundance of beneficial bacteria, and improved the contents of short-chain fatty acids in mice's cecum contents.
