A study was conducted to determine the effects of treating and reusing poultry chiller water in a commercial poultry processing facility. Broiler carcasses and chiller water were obtained from a commercial processing facility which had recently installed a TOMCO Pathogen Management System to recycle water in sections 2 and 3 of two 3-compartment chillers. In this system, reused water is blended...

Microbes have a dominant role in nutrient cycling processes the world’s deserts, where growth and activity are limited by availability of water. In order to understand dynamics water desert system how it may affect soil microbiome, we analysed temperature relative humidity fluctuations recorded between April 2018 2020 across precipitation gradient Namib Desert compared them with data from satel...

Concern about the production in mine waste dumps of acid drainage water containing high levels of sulphate and metal ions initiated the research of this project into the possibility of chemically inhibiting the bacteria responsible for the acid formation in the dumps. Research in the U.S.A. indicated that such treatment of dumps might be effective. Two types of dump have been investigated, name...

Water samples from clay storage jugs ("zeers") located in homes and at public watering stands ("sebeels") at streets, mosques, and schools were examined. Coliforms, fecal coliforms, and fecal streptococci were detected in 100, 69, 88, and 91.56% of the samples, respectively. The general microbiology of the water and some factors affecting microbial load were studied. The predominant bacterial g...

In this paper, the author reviews the reasons for the current interest in waterborne transmission of infectious agents in the veterinary curriculum. In addition, the paper provides short summaries of some of the major zoonotic outbreaks that have caused this new interest in water-borne diseases. Some curricular recommendations are made, including: basic training in modern methodologies in micro...

IMPORTANT POINTS The following key points are discussed: • Quality control microbiology tests require controlled levels of inocula and require fresh preparations of cells for those inocula • The concentration of cells in a suspension can be estimated by optical density, but this must be confirmed by plate count • The optical density readings against cell mass are specific to the microorganism s...
