background: raw vegetables are particularly susceptible to microbial growth and, therefore, use of an effective sanitizer on these food items is of great importance. the objective of this study was to evaluate the efficacy of the vegetable disinfection protocol set forth by iranian ministry of health in reducing populations of total coliform, fecal coliform, and parasites present on lettuce. me...

the effect of microbial load on the condition index of the edible oyster, saccostrea cucullata were analysed on monthly basis during 2010 and 2011 from the three different stations (namkhana, frasergaunge and sajnekhali) of indian sundarbans. the results showed significant variation with respect to microbial load between stations and seasons, which is reflected in the tissue of edible oyster. s...

background: the objective of this study was to evaluate the efficacy of sanitization of lettuce according to the protocols set forth by iranian ministry of health and medical education for reducing populations of total coliform, fecal coliform, and helminth eggs present on lettuce. methods: in the present study, we determined the load of total coliform, fecal coliform, and parasites of lettuce....

in order to optimize sludge depth in sand drying beds under the climatic conditions of saudi arabia, the effect of initial sludge depth on the fate of pathogens was investigated.the investigation was carried out for one year in al-khobar wastewater treatment plant, where initial sludge depths of 10, 15, 20, 25, 30 and 35 cm were implemented. sludge samples were collected on 0, 1, 2, 4, 7, 14, a...

Four brands of membrane filters were examined for total and fecal coliform recovery performance by two experimental approaches. Using diluted EC broth cultures of water samples, Johns-Manville filters were superior to Sartorius filters for fecal coliform but equivalent for total coliform recovery. Using river water samples, Johns-Manville filters were superior to Sartorius filters for total col...

background: today, treated wastewater recycling and reuse has been considered for agricultural irrigation. this can potentially cause health and environmental hazards. since accessing the engelberg index for sewage is a necessity, this study was undertaken on integrated stabilization ponds (isp) of isfahan east wastewater treatment plant, isfahan, iran. methods: this cross-section study was con...

The study was conducted to determine the coliform content of shellfish Anadara antiquata from three selected areas of Davao Gulf. One shot sampling was employed in the study and it was conducted within the month of February, 2010. Test for coliform and fecal coliform was done using the multiple-tube fermentation technique through the presumptive, confirmed and fecal coliform test. Total Colony ...

background: using the sludge as fertilizer on farms is one of the options to dispose it, which due to its variety of pathogenic microorganisms, it may cause a wide range of bacterial and parasitic diseases in human and livestock. the purpose of this study is to investigate the feasibility of using dried sludge produced in municipal wastewater treatment processes to fertilize agricultural lands ...

Bacteriological effects of hydraulically dredging polluted bottom sediment in the navigation channel of the Upper Mississippi River (river mile 827.5 [about 1,332 km] to 828.1 [about 1,333 km]) were investigated. Bottom sediment in the dredging site contained high total coliform densities (about 6,800 most-probable-number total coliform index per g [dry weight] and 3,800 membrane filter total c...

Water quality data at 12 sites within an urban, a suburban, and a rural stream were collected contemporaneously during four wet and eight dry periods. The urban stream yielded the highest biochemical oxygen demand (BOD), orthophosphate, total suspended sediment (TSS), and surfactant concentrations, while the most rural stream yielded the highest total organic carbon concentrations. Percent wate...
