The causative agent of tetanus is the obligate anaerobic bacterium--Clostridium tetani. These bacteria form endospores that are able to survive long periods of exposure to air and other adverse environmental conditions. Infection generally occurs through wound contamination. We can distinguish several forms of tetanus: generalized, local and neonatal. Diagnosis of tetanus is based primarily on the patient's clinical symptoms (muscle cramps, painful back muscle spasms, generalized contractions of the arcuate curvature of the body) as well as on microbiological diagnosis. This article is a brief review of C. tetani and diagnosis of infections caused by these organisms in humans.

Background: Emerging research indicates that gut microbiota (GM) are pivotal in the regulation of immune-mediated bone diseases. Nonunion, a bone metabolic disorder, has an unclear causal relationship with GM and immune cells. This study aims to elucidate the causal relationship between GM and nonunion using Mendelian Randomization (MR) and to explore the mediating role of immune cells.

Paper mulberry () is a high-quality silage protein feed material that can help address feed shortages and support livestock development. Although some studies have investigated the relationships between microbial communities and silage quality, these relationships and the underlying community assembly processes remain complex, requiring further research to clarify them. Additionally, limited research has explored the relationship between microbial community fermentation functions and silage quality.

Background: Existing literature indicates that Gestational diabetes mellitus (GDM) and maternal obesity disrupt the normal colonization of the neonatal gut microbiota alone. Still, the combined impact of GDM and excessive gestational weight gain (EGWG) on this process remains under explored. The association between gestational weight gain before/after GDM diagnosis and neonatal gut microbiota characteristics is also unclear.
