In general, the meat contains nutrients of high biological value and susceptible to contamination by enteropathogens. One way minimizing/eliminating this is use food additives, in case meat, usually sodium sulphite. This technological resource used inhibit growth pathogenic bacteria such as Salmonella spp. thermotolerant coliforms, mandatory parameters foreseen sanitary legislation. Therefore, ...

California’s beach water quality monitoring programs are the most comprehensive in the nation. State Health Services regulations implemented in response to California Assembly Bill 411 require measurement of three indicator bacteria (total coliforms, fecal coliforms and enterococci) on at least a weekly basis at high use beaches. Regulations further require that the public be warned of possible...

Rectal swabs were taken from healthy household dogs that, insofar as could be determined, had not received antimicrobial drugs. Tetracycline-resistant coliforms comprised 80 to 100% of the total number of coliforms in 61 (65%) of the 94 dogs sampled. The median number of other resistance determinants possessed by these tetracycline-resistant coliforms was 5.1. Of the tetracycline-resistant stra...

Twenty-four growing swine and 24 growing rats were fed high-protein (34%) diets on an ad libitum basis to determine their effects on body weight, carcass characteristics, intestinal microbiological profile and visceral organ weights. High dietary fiber reduced body weight gain and gain:feed ratio in both swine and rats and decreased body fatness in swine; it increased relative kidney weight (pe...

The primary objective of this study was to assess the antibacterial sensitivity pattern of Coliforms isolates from clinical and sub-clinical mastitis to quinolones. Forty coliforms isolates from bovine clinical and subclinical mastitis were tested for antimicrobial susceptibility by measuring MIC by Resazurin dye broth microdilution method. Of the 27 E. coli isolates tested, only 7.4% of the is...

Fecal bacterial indicator analyses have been widely used for monitoring the water quality. This study was designed to determine the ratio between the density of Escherichia coli and other Thermotolerant Coliforms (TtC) bacteria from freshwater samples collected for a two-year period of monitoring. TtC were enumerated by membrane filtration on mFC agar. E. coli enumeration was done by two method...

Three methods (membrane filtration, multiple tube fermentation, and chromogenic substrate technology kits manufactured by IDEXX Laboratories, Inc.) are routinely used to measure indicator bacteria for beach water quality. To assess comparability of these methods, quantify within-laboratory variability for each method, and place that variability into context of variability among laboratories usi...

It has been indicated that probiotics can be nourished by consuming prebiotics in order to function more efficiently, allowing the bacteria to stay within a healthy balance. In this study, we investigated the effects of xylooligosaccharides- (XOS-) enriched rice porridge consumption on the ecosystem in the intestinal tract of human subjects. Twenty healthy subjects participated in this 6-week t...

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,...
