Introduction: Organic fertilizers are beneficial to maintain and improve structure of the soil nutrients; however, in case of presence of pathogenic microbial agents and pathogens inside them, it will result in health problems and disease transmission. Therefore, present study aimed to determine microbial quality of produced vermicomposts in Yazd city. Materials and Methods: This study was a d...

A rapid 7-h fecal coliform (FC) test for the detection of FC in water has been developed. This membrane filter test utilizes a lightly buffered lactose-based medium (m-7-h FC medium) combined with a sensitive pH indicator system. FC colonies appeared yellow against a light purple background after incubation at 41.5 degrees C for 7 to 7.25 h. Comparison of FC test results showed that the mean ve...

Constructed treatment wetlands have been found to remove fecal coliform (FC) through a variety of mechanisms. This research evaluated the removal of FC in both warm and cold seasons from surface flow treatment wetlands in Bible Hill, Nova Scotia. Two wetlands (100 m), of differing depths were monitored over a 17 month period. The wetlands were loaded with dairy wastewater (average inlet FC conc...

Sixty raw milk samples commercialized without due authorization in the counties of Botucatu and S. Manuel, State of S. Paulo (Brazil), were submitted to mesophilic microorganism and coagulase-positive Staphylococcus and most probable number of total coliform and fecal coliform counts. Forty-one (68.3%) and 50 (83.3%) of the samples were found, respectively to contain mesophilic microorganisms a...

Coliform tests were performed on 85 hide and 75 meat samples. IMViC reactions were determined on isolates from positive confirmed and fecal tests, and strains other than Escherichia coli were identified. Strains typed as Aerobacter aerogenes types I and II were identified as Enterobacter cloacae (51.4%), Klebsiella pneumoniae (21.5%), Enterobacter aerogenes (15%), and Enterobacter liquefaciens,...

This study evaluated the bacteria removal efficiency, re-suspension and survivability within two structural Best Management Practices (BMPs) called Vortechs installed at two different sites in Providence, Rhode Island. Twelve rain storms were sampled during years 2004 and 2005. Five pathogenic indicator bacteria, E. coli, enterococci, fecal streptococci, total coliform, fecal coliform, were ana...

Status of drinking water contamination was studied in three mountainous districts in Nepal. A total of 43 water samples (Sankhuwasabha: 11, Rasuwa: 12 and Dolpa: 20) were tested for the presence of total coliform (TC) and Escherichia coli as fecal coliform bacilli using commercially available test system called Colilert (Japan). Of the total, 85.7% (36/43) were positive for TC whereas 67.4% (29...

Agricultural runoff influenced by nonpoint pollution frequently exceeds the USEPA standards for bacterial contamination of primary contact water (200 fecal coliforms/100 mL). Few studies bave evaluated the effect of cattle (Bos taurus) grazing on fecal contamination of ground water in the karst topography of central Kentucky. Our objectives were to: (i) observe the extent and pattern of fecal b...

BACKGROUND The aim of present work was to assess the concentration levels as well as vertical distribution of indicator bacteria including total coliform, fecal coliform, Pseudomonas aeruginosa, and Heterotrophic Plate Count (HPC) in the marine environment (seawater and coastal sediments) and evaluate the correlation between indicator bacteria and some physicochemical parameters of surface sedi...
