A medium composed of 0.009% sodium azide, 0.07% sodium deoxycholate, and 0.0007% ethyl violet in Brain Heart Infusion Agar (Difco) and a process of incubation in an atmosphere of 90% N(2) and 10% CO(2) for the selective isolation of certain members of the intestinal bacteroides are described. The medium appears to select predominantly members of the genus Bacteroides and a few of the genus Spha...

STUDY OBJECTIVE To find out whether bathing in sewage polluted waters implies a danger to bathers' health and to determine the best microbiological indicator to predict the relation between bathing and the appearance of some symptoms. DESIGN Cohort study. SETTING City of Santander (north of Spain). PARTICIPANTS From the people going to four Santander beaches in the period from 1 July to 1...

Coliform group has been extensively used as an indicator of drinking water quality and historically led to the public health protection concept. Multiple tube fermentation technique has been currently used for assessment of the microbial quality of drinking water. This method, however, has limitations. Enzymatic assay constitute an alternative approach for detecting indicator bacteria, namely t...

For the past century, public health officials have relied on fecal coliforms to identify and track bacterial contamination. However, several issues arise when using coliforms as indicators for viral pathogen risk. First, there is a lack of association between fecal coliforms and human enteric viruses in the environment. Second, there are differences in the fate of coliforms compared to viral pa...

This study was conducted to evaluate the effects of dietary supplementation with cinnamon powder, cinnamon oil, and synbiotic as growth promoter agents on growth performance, blood parameters, and intestinal microbial populations in Japanese quails. A total of 420 one-day-old Japanese quails were randomly assigned to 7 treatments with 4 replicates. The dietary treatments consi...

a total of 240, one-day-old quail chicks (coturnix coturnix japonica) were used to study the effects of artichoke leaf meal (alm) and vitamin e in diet on growth performance, ileal microbial populations and intestinal morphology in a 42-d trial. this experiment was performed as a completely randomized design with 4 replicates of 15 quails each, using a 4 × 2 factorial arrangement with diet and ...

D. H. M. JOYNSON AND C. H. L. HOWELLS (Public Health Laboratory, University Hospital of Wales, Cardiff) Samples of animal feeding stuffs were examined for the presence of Gram-negative, lactosefermenting organisms (hereafter called coliforms) and the antibiotic resistance of any strain isolated was determined. Coliforms were found in 13% of all the feeds examined and of these organisms 64-4% we...

Most of present traditional ice cream from hygienic quality has non-conforming with extant standards. Pasteurization of primary ice cream mixture with sufficient thermal processing increase hygienic quality level and causes control of primary infection. Origins of infection for traditional ice cream consist of: use of infected primary materials (milk or cream) or non-pasteurization of them. Stu...

In raw sludges and in mesophilically and thermophilically digested anaerobic sludges, large variations in numbers of viruses occurred over narrow ranges of numbers of fecal coliforms, total coliforms, and fecal streptococci, demonstrating that the bacteria were poor quantitative reflectors of the numbers of the viruses detected. Mesophilic and thermophilic digestion of anaerobic sludges destroy...

The microbiological safety of raw cow milk from collection centers of three regions in the north-east of Morocco has been studied. It involved 80 samples and was extent over a period of three years. The samples were analysed for the enumeration of Total Plate Count (TPC), total coliforms (TC), fecal coliforms (FC), Staphylococcus aureus (S. aureus) as well as the prevalence of pathogens such as...
