Diverse land use activities can elevate risk of microbiological contamination entering stream headwaters. Spatially distributed water quality monitoring carried out across a 17 km(2) agricultural catchment aimed to characterize microbiological contamination reaching surface water and investigate whether winter agricultural land use restrictions proved effective in addressing water quality degra...

Contamination of surface waters with fecal pathogens has been linked to many outbreaks of human illness worldwide. The objective of this study is to evaluate the environmental factors that influence pathogen mortality in exposed manure and their initial migration from manure to the surface water. A 13 mm thickness of manure was held at constant environmental conditions for more than 6 weeks. Co...

A lactate dehydrogenase-deficient (Ldh-) mutant of a human isolate of Streptococcus mutans serotype c was tested in a gnotobiotic rat caries model. Compared with the wild-type Ldh-positive (Ldh+) strains, it was significantly (alpha less than or equal to 0.005) less cariogenic in experiments with two different sublines of Sprague-Dawley rats. The Ldh- mutant strain 044 colonized the oral cavity...

Narta Lagoon is one of the biggest Lagoons in Albania. It situated southern part Vjosa River delta. Two canals northwest and southwest parts lagoon connect it to Adriatic Sea. These artificial enable water exchange process with sea during tidal flow. Vjose - area considered a Protected Landscape, so environmental monitoring important. Setting design: Water samples were taken monthly, at six eve...

Objective: The present study investigates the diversity, and distribution of harmful microbes in sediments and groundwater of Tuticorin Corporation. The faecal pollution indicators such as, Total coliform bacteria, Faecal coliform bacteria, Escherichia coli, Faecal streptococci were investigated in the sediments and groundwater samples from 12 locations in the study area. Methods: Groundwater a...
