Background: Although the pathogenesis of is well-defined, the origin and transmission of the bacterium have remained largely unknown. The water transmission hypothesis suggested that water acts as a carrier in oral-fecal transmission, especially in high-prevalence areas. We aimed to evaluate the possible contamination of tap water with infective in Kermanshah, Iran from Sep-Oct 2020.
Methods: Tap water samples were collected from varieties of probable high-alert regions and the viability of were achieved using culture and real-time PCR techniques ( gene expression).
Results: Out of 50 tap water samples, 3 were positive for before enrichment and 6 were positive after enrichment by RT qPCR, while colonies of two samples were observed on brucella agar plates.
Conclusion: The results of positive samples demonstrated the probable presence of viable in tap water samples, showing that tap water distribution systems could be a potential route for transmission.

Maintaining proper hydration is crucial for human health, physiological functions, and cognitive performance. This study sought to determine the hydration status and the microbial safety of tap water in an urban setting (Kwame Nkrumah University of Science and Technology Campus) and a rural community (Adjamesu) in the Ashanti Region of Ghana. The water safety perception and hydration status of 171 study participants aged 10-61 years were assessed.

A new rhodamine based turn on florescent probe ()-3',6'-bis(ethylamino)-2-(((6-methoxy-2-oxo-1,2-dihydroquinolin-3-yl)methylene)amino)-2',7'-dimethylspiro[isoindoline-1,9'-xanthen]-3-one (RME) was efficiently synthesized through a simple condensation reaction of 2-amino-3',6'-bis(ethylamino)-2',7'-dimethylspiro[isoindoline-1,9'-xanthen]-3-one and 6-methoxy-2-oxo-1,2-dihydroquinoline-3-carbaldehyde. The receptor RME is highly non-fluorescent and when copper ions (Cu ions) are added in DMF/water (1 : 2, v/v) medium, the receptor RME exhibits a specific "turn-on" colorimetric and fluorometric response. Moreover, RME binding with Cu ions produced a remarkable color variation that was perceptible to the human eye, changing from colorless to pink.

Objective: To investigate the prevalence of parasitic infections in market-sold aquatic products in Shanghai Municipality, and to understand the knowledge and practice towards food-borne parasitic diseases among residents, so as to provide insights into the surveillance and control of food-borne parasitic diseases.
Methods: Freshwater products, seawater products and pickled products were randomly obtained from agricultural trade markets, supermarkets, retail stores and restaurants in Huangpu, Putuo, Minhang and Qingpu districts of Shanghai Municipality from 2020 to 2023. Parasite metacercariae and larvae were detected in these aquatic products using pressing method, digestion method and the dissection method, and the detection of parasitic infection was compared in different types of aquatic products.

Introduction: Contamination of drinking water by can cause serious diseases, including cancer. The determinants of the infection rate are socioeconomic status, low standard of living and overcrowding. In addition, exposure to environmental sources contaminated with feces, such as water and vegetables, is another risk factor for infection.

Anions play a crucial role in various environmental, chemical, and biological processes. Among various anions, the production of perchlorate (ClO ) ion is expected to rise in upcoming years, and thus, an efficient method for the detection of perchlorate ion is highly desirable. In this effort, a pyridyl-benzimidazole-based luminescent probe (RSB1) containing two N-H donor sites has been synthesized for selective detection of perchlorate ion.
