The authors examined Varese lake water for the research of Vibrios. The research was extended to the determination of fecal Coliforms, Salmonellae and chemical parameters. Three strains of Vibrio cholerae non 0-1 were isolated in three Moore tampons among 18 tampons examined . Any association between chemical parameters, determination of fecal Coliforms and the presence of Salmonellae and Vibrio cholerae non 0-1 was impossible.

Cholera remains a significant public health challenge in Nigeria, with recurrent outbreaks exacerbated by inadequate water, sanitation, and hygiene (WASH) infrastructure, as well as conflict and displacement. This review examines cholera outbreaks in Nigeria from 2010 to 2024, analyzing epidemiological trends, contributing factors, and public health responses. Seasonal peaks during periods of heavy rainfall and flooding have consistently facilitated transmission, with Northern regions disproportionately affected due to poor infrastructure and ongoing conflicts.

Waterborne bacteria pose a serious hazard to human health, hence a precise detection method is required to identify them. A photonic crystal fiber sensor that takes into account the dangers of aquatic bacteria has been suggested, and its optical characteristics in the THz range have been quantitatively assessed. The PCF sensor was designed and examined as computed in Comsol Multiphysics, a program in which uses the method of "Finite Element Method" (FEM).

Objective: This study aims to explore the therapeutic mechanism of Massa Medicata Fermentata (MMF) with different formulations on spleen deficiency constipation in mice by analyzing gastrointestinal hormones, D-xylose, intestinal microbiota, and intestinal enzyme activities.

Methods: A spleen deficiency constipation model was established using an oral administration of Sennae Folium decoction combined with controlled diet and water intake. After successful model establishment, the mice with spleen deficiency constipation were treated with MMF S1, S2, S3.
