Antimicrobial susceptibilities of 23 strains of Desulfovibrio spp. were tested by Etest. Generally, Desulfovibrio spp. were highly susceptible to sulbactam-ampicillin, meropenem, clindamycin, metronidazole, and chloramphenicol: MIC(90)s of 6, 4, 0.19, 0.25, and 8 microg/ml, respectively. In addition, these strains generally showed high MICs to piperacillin and piperacillin-tazobactam. Desulfovibrio fairfieldensis (eight strains) was the species least susceptible to most agents, especially beta-lactams, and was the only species resistant to fluoroquinolones. Desulfovibrio desulfuricans strain Essex 6 isolates were less susceptible to beta-lactams than D. desulfuricans strain MB isolates.

Partial replacement of soybean with local alternative sources: effects on behavior, cecal microbiota, and intestinal histomorphometry of local chickens.

Interest in partially replacing soybean meal in poultry diets with alternative protein sources such as agri-industrial by-products and black soldier fly (BSF, ) has gained significant attention due to sustainability concerns. This study aimed to evaluate the effects of broiler diets in which soybean meal was partially substituted with agri-industrial by-products with or without BSF larvae meal, on the behavior, intestinal histomorphometry, and microbiome profile of a local broiler chicken strain. There were three dietary treatments.

Article Synopsis
- Prostate cancer development is influenced by lifestyle factors and gut microbiome changes, with a specific link to gut dysbiosis, but the exact mechanisms are still unclear.
- The study analyzed stool samples from tumor-bearing mice and humans to investigate the relationship between gut microbes and prostate cancer status, identifying key bacterial taxa associated with the disease.
- Results indicate that both humans and mice show distinct gut microbiome profiles related to prostate cancer, highlighting potential bacterial metabolites that may promote the disease and suggesting a preclinical model for further research.
Low dose rifaximin combined with N-acetylcysteine is superior to rifaximin alone in a rat model of IBS-D: a randomized trial.

Article Synopsis
- Rifaximin is FDA-approved for treating IBS-D but has limited effectiveness due to poor solubility impacting its ability to target E. coli in the mucus layer.
- Adding N-acetylcysteine (NAC) enhances rifaximin's efficacy against E. coli, as shown through tests in both lab assays and a rat model of IBS-D.
- The combination of rifaximin and NAC effectively normalized stool consistency and bacterial levels in the rat model, suggesting potential for improved treatment responses in IBS-D patients.

The human gut flora comprises a dynamic network of bacterial species that coexist in a finely tuned equilibrium. The interaction with intestinal bacteria profoundly influences the host's development, metabolism, immunity, and overall health. Furthermore, dysbiosis, a disruption of the gut microbiota, can induce a variety of diseases, not exclusively associated with the intestinal tract.

Microplastics (MPs) are widespread contaminants highly persistent in the environment and present in matrices to which humans are extensively exposed, including food and beverages. MP ingestion occurs in adults and children and is becoming an emerging public health issue. The gastrointestinal system is the most exposed to MP contamination, which can alter its physiology starting from changes in the microbiome.
