Item Metadata only Decreases of coliform bacteria in drinking water stored in large cement jars(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Uraiwan Inmuong; Komol SivaborvornPublication Metadata only Development of multiplex PCR for the detection of total coliform bacteria for Escherichia coli and Clostridium perfringens in drinking water(2005-01-01) Suwalee Tantawiwat; Unchalee Tansuphasiri; Waranya Wongwit; Varee Wongchotigul; Dwip Kitayaporn; Mahidol UniversityMultiplex PCR amplification of lacZ, uidA and plc genes was developed for the simultaneous detection of total coliform bacteria for Escherichia coli and Clostridium perfringens, in drinking water. Detection by agarose gel electrophoresis yielded a... band of 876 bp for the lacZ gene of all coliform bacteria; a band of 147 bp for the uidA gene and a band of 876 bp for the lacZ gene of all strains of E. coli; a band of 280 bp for the plc gene for all strains of C. perfringens; and a negative resultItem Metadata only Reduction and regrowth of total coliform bacteria, fecal coliform bacteria, and E. coli after chlorine and peracetic acid disinfection in the hospital effluent(2024-02-01) Suwannasin S.; Sreesai S.; Warodomrungsimun C.; Singhakant C.; Magun W.; Suwannasin S.; Mahidol Universityhigher efficiency in reducing total coliform while PAA was greater for E. coli. The efficiencies increased as contact time was increased. PAA exhibited higher physical and chemical treating capacities than those of chlorine. The study suggestedPublication Metadata only Influence of enrichment broths on multiplex pcr detection of total coliform bacteria, escherichia coli and clostridium perfringens, in spiked water samples(2009-07-01) S. Worakhunpiset; P. Tharnpoophasiam; Mahidol UniversityAlthough multiplex PCR amplification condition for simultaneous detection of total coliform bacteria, Escherichia coli and Clostridium perfringens in water sample has been developed, results with high sensitivity are obtained when amplifyingItem Metadata only Effect of preservative substances on coliform numbers in water-samples for bacteriological examination(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Sunun Limsawat; Komol sivaborvorn; Krisana Teankaprasith; Rawiwan RojanavipartPublication Metadata only Microbiological quality of drinking water and using water of a Chao Phya River community, Bangkok.(1994-12-01) P. Luksamijarulkul; V. Pumsuwan; S. Pungchitton; Mahidol Universityroutine testing of the bacteriological quality of drinking water is designed to detect the presence of coliform bacteria and virological assessment is to detect the presence of enteric viruses, especially hepatitis A virus (HAV). Therefore, this study... attempted to determine the HAV and coliform bacteria contamination in drinking water and using water of a Chao Phya River community, Bangkok where crowded living conditions increase the risk of water-related diseases. 95 samples of drinking water and 75Item Metadata only Survival of coliform bacteria in soil applied with fecal sludge and sewage sludge after passing through various drying processes(Mahidol University. Mahidol University Library and Knowledge Center, 2001) Atika Rongsawad; Siranee Sreesai; Kanokrat Siripanichgon; Pakorn Sumethanurugkul; Shalasai HuangprasertItem Metadata only Water Use Quality Situation over 10 Years (2010 to 2019) of Hospitals under the Ministry of Public Health, Thailand(2022-05-01) Peeratoranit T.; Sreesai S.; Sillabutra J.; Mahidol Universityindicators; total coliform bacteria (43.9%) and fecal coliform bacteria (33.2%). Water parameters related to exceeded total and fecal coliform bacteria standards included turbidity, nitrate, chloride and pH levels. The highest explicit turbidity relationship... of occurrence probability exceeded the quality standards with total and fecal coliform bacteria 3.7 and 4.3 fold, respectively. Onsite hospital water treatment is needed to ensure safe conditions. The significant chemical parameters can be used as a rapid toolPublication Metadata only Bacterial contamination of vegetables served in hospitals.(2005-12-01) Chertsak Dhiraputra; Chuntima Tiensasitorn; Wanida Techachaiwiwat; Naruemol Jirapanakorn; Kanchana Kachintorn; Somwang Danchaivijitr; Mahidol UniversityOBJECTIVES: To study bacterial contamination of fresh vegetables before cleaning and before serving to patients in 14 hospitals. MATERIAL AND METHOD: Aerobic plate count was performed and emphasized on total viable aerobic bacteria, fecal coliform... interviewed. RESULTS: One hundred and six of 403 of fresh vegetable samples (26.3%) before cleaning were contaminated with > 10(7) colony forming unit per gram (CFU/gram) of viable aerobic bacteria, 106 of 178 samples (59.6%) contained MPN/fecal coliform >1Publication Metadata only Assessment of a potential agricultural application of Bangkok-digested sewage sludge and finished compost products(2013-09-01) Siranee Sreesai; Panadda Peapueng; Taninporn Tippayamongkonkun; Suthipong Sthiannopkao; Mahidol University; Center of Excellence on Environmental Health and Toxicology; National Cheng Kung UniversityA study was conducted to investigate the levels of plant nutrients, heavy metals, parasites and fecal coliform bacteria in Bangkok-produced sewage sludge and finished compost products for potential agricultural application, as well as to compare... (1.16 ± 0.22%), but it was contaminated with human pathogens, including fecal coliform bacteria, viable helminthes egg and active forms of parasite cysts. Thus, fresh sewage sludge should not be disposed on land unless it has undergone pathogen
