GELDREICH E. E. (Division of Water Supply and Pollution Control, U.S. Public Health Service, Cincinnati, Ohio), B. A. KENNER, AND P. W. KABLER. Occurrence of coliforms, fecal coliforms, and streptococci on vegetation and insects. Appl. Microbiol. 12:63-69. 1964.-This study considers the sanitary significance of coliforms, fecal coliforms, and streptococci isolated from 152 species of plants and...

A two-layer membrane filtration (MF) medium (injury-mitigating MF [IM-MF]) and a procedure for the enumeration of injured fecal coliforms are described. These procedures included the addition of glycerol and acetate plus reducing agents to both layers of a two-layer medium and rinsing of the filter with a rich resuscitation medium. Some changes in incubation time and temperatures were used. Thi...

haraz river originates from the northern slopes of the alborz and is flowed in a relatively broad valley. there are several village, sector, twenty sand factories and fish culture farms alongside of this river. in addition, restaurants and rest place for travelers sometimes used as a place. this study was performed to study the coliform contamination of ground water along the haraz river.in thi...

Many recreational beaches suffer from elevated levels of microorganisms, resulting in beach advisories and closures due to lack of compliance with Environmental Protection Agency guidelines. We conducted the first statewide beach water quality assessment by analyzing decadal records of fecal indicator bacteria (enterococci and fecal coliform) levels at 262 Florida beaches. The objectives were t...

The accepted method for determining disinfection efficiency of wastewater treatment systems is routinely to perform fecal coliform bacteria analyses on the final effluent (5). Standard Methods for the Examination of Water and Wastewater outlines two procedures for fecal coliform analysis: the membrane filtration technique and the most-probable-number (MPN) method (1). For chlorinated effluents,...

Survival of total and fecal coliform bacteria was measured in the 0 to 5, 5 to 15, and 15 to 30 cm soil depths at 1, 3, 7, 14, and 90 to 120 d after swine (Sus scrofa) wastewater application to riparian filterstrips in southern Georgia during each season of the year. Vegetative treatments evaluated were: (i) 20 m grass-10 m forest, (ii) 10 m grass-20 m forest, and (iii) 10 m grass-20 m maidenca...

Our aim to establish the metal (Pb, Cd, Cr, Cu and Zn) levels of Mammalian scat samples deriving from sanctuaries of western Rajasthan and comaprision between the concentrations of Talchaper Blackbuck Sanctuary, Churu and Dhavadoli Protected Area, Jodhpur. Restric tions on the sampling because of Wildlife Protection Act (1972) prevents taking of samples of living tissues to analyse body burdens...

A sewer main serving a large municipal wastewater system ruptured, discharging approximately 3,000,000 gallons (11,355,000 L) of raw human sewage into a multi-branched tidal creek estuary along the US East Coast. The biochemical oxygen demand caused severe hypoxia in the system, causing a large fish kill. The sewage load led to high fecal coliform bacteria concentrations in the creek (maximum o...

Concentrations of thermotolerant coliform bacteria, presumptive E. coll, and presumptive fecal streptococci were determined from ditches, brooks, and natural ponds in six agricultural areas and 22 uninhabited pristine areas in southern Finland in the summer of 1987. For comparison, the same fecal indicators were enumerated from the effluents of three wastewater t eatment plants. The objective w...

The aim of this article was to define the sampling level and method combination that captures antibiotic resistance at pig herd level utilizing qPCR antibiotic resistance gene quantification and culture-based quantification of antibiotic resistant coliform indicator bacteria. Fourteen qPCR assays for commonly detected antibiotic resistance genes were developed, and used to quantify antibiotic r...
