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 Open Access The removal of colors in non-carbonated soft drinks using granular activated carbon for coliform bacteria detection by sanitary indicator medium(2009) Vatanasomboon, P; Pisit Vatanasomboon; Rojanavipart, P; Piangchan Rojanavipart; Luksamijarulkul, P; Pipat Luksamijarulkul; พิศิษฐ์ วัฒนสมบูรณ์; เพียงจันทร์ โรจนวิภาต; พิพัฒน์ ลักษมีจรัลกุล; Srisantisang, N; Mahidol University. Faculty of Public Health. Department of Environmental Health Science; Mahidol University. Faculty of Public Health. Department of Biostatistics; Mahidol University. Faculty of Public Health. Department of MicrobiologyThis research was designed to study the efficiency of non-carbonated soft drink color removal by using granular activated carbon (GAC) for coliform bacteria detection by SI medium. The conditions established in the study were to use 6 color tones... for blue color-tone. The validity of coliform bacteria detection by SI medium for these removed-color soft drinks when compared with the standard MPN method were sensitivity value, specificity value and efficiency of test of more than 80%. Thus, GAC canPublication 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.

The results revealed that counts of total bacteria, Staphylococcus aureus, and fecal coliforms in aseptically shucked oysters, were significantly lower than those same measurements in freshly-shucked oysters (p.... Fresh water exceeded the standards for total bacteria and coliforms in all samples, both before and after washing. The 40% of unwashed and 50% of washed shucked oysters exceeded the standard for total bacteria. The results indicated that bacterialPublication 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.
