Assessing the potential threat of fecal contamination in surface water often depends on model forecasts which assume that fecal indicator bacteria (FIB, a proxy for the concentration of pathogens found in fecal contamination from warm-blooded animals) are lost or removed from the water column at a certain rate (often referred to as an "inactivation" rate). In efforts to reduce human health risk...

random samples from asymptomatic leaves and branches of five native medicinal plants: stachys lavandulifolia, rumex pulcher, hypericum scabrum, starja bachteriarica and achillea kellalensis were collected from chaharmahal province of iran and examined for the presence of endophytic bacteria and fungi with biological activity. from 8 isolated endophytic fungi, all displayed considerable activity...

The aim of this study was to investigate the impact on numbers of using different media for the enumeration of Escherichia coli subjected to stress, and to evaluate the use of different resuscitation methods on bacterial numbers. E. coli was subjected to heat stress by exposure to 55 degrees C for 1h or to light-induced oxidative stress by exposure to artificial light for up to 8h in the presen...

The fundamental advantage of using automated urine analyzers lies in the current grouping of laboratories as technical divisions. The UF1000i(®) Biomérieux is a 2(nd) generation automated urine analyzer which uses fluorescence flow cytometry to count the particles and bacteria present in urine. It also provides a prediction indicator for the urinary tract infection, based on the leukocyte and b...

Continuous faecal pollution in source water is a global problem that is particularly debilitating to rural communities that are directly dependent on untreated source water for all their domestic and other purposes. The elevation of indicator bacteria levels (such as the faecal coliforms) in the water may pose a public health risk. This study reports the results of microbial monitoring of the M...

Although urban wet weather discharges may have elevated concentrations of fecal indicator bacteria impacting water quality at swimming beaches, not all of these bacteria may arise from human sources. In this study, the contribution of non-human fecal indicator bacteria was quantified by sampling coastal reference beaches in southern California. Samples were collected at beaches near stormwater ...

To determine the prevalence of indicator bacteria resistant to antimicrobials among poultry in three Southeast Asian countries (Vietnam, Indonesia and Thailand), we examined the antimicrobial susceptibilities of commensal bacteria isolated from chickens. In total, 125, 117 and 180 isolates of Escherichia coli, Enterococcus faecalis and Enterococcus faecium, respectively, were used to test for a...

The fate of indicator bacteria, a bacterial pathogen, and total aerobic bacteria during aerobic and anaerobic digestion of wastewater sludge under laboratory conditions was determined. Correlation coefficients were calculated between physical and chemical parameters (temperature, dissolved oxygen, pH, total solids, and volatile solids) and either the daily change in bacterial numbers or the per...
