Substrates composed of hay residues, dung, and urine accumulate around winter hay feeding sites in cattle pastures, providing developmental habitats for stable flies. The objective of this study was to relate physiochemical and microbial properties of these substrates to the presence or absence of stable fly larvae. Properties included pH, temperature, moisture, ammonium concentration, electric...

Microbiological and physicochemical characteristics of swimming pools in South Eastern states of Nigeria (Akwa Ibom and Cross River) were investigated. The bacterial isolates included Enterococcus faecalis, Clostridium perfringens, Bacillus cereus and Escherichia coli. Others were Pseudomonas aeruginosa, Staphylococcus aureus, Proteus vulgaris and Staphylococcus epidermidis, while fungal isolat...

The microbial water quality at two beaches, Hobie Beach and Crandon Beach, in Miami-Dade County, Florida, USA was measured using multiple microbial indicators for the purpose of evaluating correlations between microbes and for identifying possible sources of contamination. The indicator microbes chosen for this study (enterococci, Escherichia coli, fecal coliform, total coliform and C. perfring...

A survey of the microbiological and chemical quality of water supplies in the Bindura urban and peri-urban area was carried out over a three year period from January 2000 to July 2003. Bindura is the provincial city of Mashonaland Central, situated 88 km from the national capital, Harare. Large-scale farming and mining activities in the area predispose water bodies to eutrophication and chemica...

That some strains of the coliform group of bacteria exert inhibitory effects on other microorganisms, when grown in association in liquid media, was reported first by Nissle in 1916. Because of the multiplicity of factors involved when organisms are growing in heterogeneous mixtures in liquid media, the nature of the inhibiting agent is difficult to ascertain. Gratia of Belgium (1925) observed ...
