Analysis of microbe diversity in freshwater resources and nearshore seawater samples Upolu Island was performed to investigate the distribution harmful bacteria. For this, 124 were collected from 23 river systems, two volcanic lakes, 45 locations inside outside barrier reef Island, Samoa. Physicochemical parameters for general water quality, detection coliform bacteria 16S rRNA amplicon sequenc...

A 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 the quality of compost under different composting conditions. The results indicated that digested sewage sludge had high fertilizing values for organic...

introduction: one of the methods for disposal of sludge is its usage as fertilizer on agricultural. the purpose of this study was to analyze the possibility in the application of sludge to agricultural, according to environmental standards. methods: this descriptive-analytic study was conducted for 12 months on dried sludge wastewater treatment plant in yazd. monthly sampling and tests were per...

M anaging microbes from urban watersheds can be a daunting task, as bacteria are usually present in high concentrations during storms, come from many different sources, and follow many complex pathways to reach receiving waters. In this article, we examine whether it is technically feasible to reduce microbes in urban stormwater to maintain drinking water, water contact recreation and shellfish...

Low levels of fecal indicator bacteria (FIB) were recently detected in two reclaimed water open-air ponds used to irrigate a golf course located in Northeastern Spain. The aim of this study was to evaluate the feasibility of a biochemical fingerprinting method to track the origin of fecal contamination in water with low FIB levels, as in the aforementioned ponds. We also aimed to determine whet...

Fecal contamination of bedding has been associated with coliform mastitis caused by E. coli, while coliform mastitis caused by Klebsiella spp. is associated with wet sawdust and wood shavings.(1) Coliform mastitis has an average incidence rate of 15% to 20% in herds with low somatic cell counts (SCC) and is implicated in 30% to 40% of clinical cases. It is a common cause of fatal mastitis in ca...

Total coliform (TC), fecal coliform (FC), and fecal streptococcal (FS) numbers were monitored for 3 years to determine the effect of grazing on the presence of these organisms in runoff from a cattlegrazed and a nongrazed watershed in the Pacific Northwest. The watersheds were characterized by winter precipitation and summer grazing. Weighted-average numbers of TC and FS in runoff did not appea...

Studies were initiated to investigate the interactions between heterotrophic plate count bacteria and coliform organisms. We used spiked samples to show that heterotrophic plate count bacteria could reduce coliform densities by more than 3 logs within 8 days. Some heterotrophic plate count bacteria were able to cause injury to the coliform population. A significant correlation (r = 0.66; P less...
