The coliform bacterial population in the Grand Forks, N.Dak. sewage system was examined for multiple-antibiotic-resistant organisms over a 1-year period. Multiple-antibiotic-resistant coliforms were found to be common in the sewage, and their numbers remained fairly constant relative to the total coliform population throughout the year. Resistance to kanamycin, tetracycline, and ampicillin was ...

BACKGROUND Samples of drinking water were collected directly from the personal water bottles of students at an elementary school in Calgary, Alberta. METHODS Total and fecal coliforms and heterotrophic bacteria were enumerated using membrane filtration and agar plate count methods respectively. RESULTS The Canadian Drinking Water Quality Guidelines (CWQG) criterion was exceeded for total co...

Potential antimicrobial activity of follicular fluid and its selectivity remains open questions in field of human and animal reproduction. In our work we examine antimicrobial activity of porcine follicular fluid on coliform bacteria, as Gram-negative, and B. cereus, as Gram-positive, by incubation of different dilatations of bacteria with follicular fluid in cultivation medium and microbiologi...

Several methods have been suggested for the accurate, rapid, and convenient detection and enumeration of Escherichia coli in potable waters, stream samples, sewage, and in certain food products. The first of these procedures was described by Eijkman who proposed a "fecal coli" test that he believed differentiated between coliforms from the gut of warm-blooded animals and strains originating fro...

abstract aims: turbidity in higher than standard levels, indicates failure in the water treatment plant. an electrochemical disinfection process takes place through electricity transition between two or more electrodes. this research aimed to determine the reaction rate of electrochemical process for purification of polluted water. materials & methods: this is a bench scale, experimental study ...
