Fecal contamination of drinking water is a major health problem which accounts for many cases of diarrhea mainly in infants and foreigners. This contamination is a complex interaction of many parameters. Antibiotic resistance among bacterial isolates complicates the problem. The study was done to identify fecal contamination of drinking water by Diarrheagenic Antibiotic-Resistant in Zagazig city and to trace reasons for such contamination, three hundred potable water samples were investigated for existence. Locations of positive samples were investigated in relation to population density, water source, and type of water pipe. Sixteen strains were isolated. Antibiotic sensitivity was done and enterotoxigenic, enteropathogenic, and enterohaemorrhagic virulence genes were investigated by PCR. Probability of fecal contamination correlated with higher population density, with increased distance from Zagazig water plant, and with asbestos cement water pipes. Resistance to at least one antimicrobial drug was found in all isolates. Virulence genes were detected in a rate of 26.27%, 13.13%, 20%, 6.67%, and 33.33% for LT, ST, stx1, stx2, and eae genes, respectively. This relatively high frequency of fecal contamination points towards the high risk of developing diarrhea by antibiotic resistant DEC in low socioeconomic communities particularly with old fashion distribution systems.

Cola beverage reduces risk of lead poisoning from accidental ingestion of contaminated soil particles in rat and swine models.

Accidental ingestion of lead (Pb)-contaminated soils represents a major route of Pb exposure for both adults and children, and the development of accessible and cost-effective solutions to reduce Pb poisoning is urgently required. Here, we present an effective and straightforward technique, involving the consumption of cola beverages, for the purpose of lowering blood Pb levels following the ingestion of contaminated soils in animal models. This method facilitated the direct passage of Pb in contaminated soil through the digestive system, enhancing its elimination without absorption into systemic circulation.

Tomato brown rugose fruit virus (ToBRFV) has emerged as a major plant pathogen with the potential to spread through contaminated wastewater, posing risks to agriculture and public health. This study evaluated ToBRFV as a human-specific microbial source tracking (MST) marker in Thailand, comparing its performance to crAssphage. Using qPCR assays, ToBRFV was detected in 62.

Hepatitis E virus (HEV) is the most common cause of acute viral hepatitis, responsible for large outbreaks in resource limited countries. The virus belongs to the genus Orthohepevirus which is subdivided into eight distinct genotypes (HEV-1 to HEV-8). Human disease transmission is mostly through the faecal-oral route.

Antibiotic resistant bacteria are increasingly being found in aquatic environments, representing a potential threat to public health. To examine the dynamics and potential sources of antibiotic-resistant genes (ARGs) in urbanised waterways, we performed a six-month temporal study at six locations within the Sydney Harbour estuary. These locations spanned a salinity gradient from seawater at the mouth of the harbour to freshwater at the more urbanised western sites.

In integrated crop-livestock systems, livestock graze on cover crops and deposit raw manure onto fields to improve soil health and fertility. However, enteric pathogens shed by grazing animals may be associated with foodborne pathogen contamination of produce influenced by fecal-soil microbial interactions. We analyzed 300 fecal samples (148 from sheep and 152 from goats) and 415 soil samples (272 from California and 143 from Minnesota) to investigate the effects of grazing and the presence of non-O157 Shiga toxin-producing Escherichia coli (STEC) or generic E.
