It is important that indicators of fecal pollution are reliable. Coliform bacteria are a commonly used indicator of fecal pollution. As other investigators have reported elsewhere, we observed a seasonal pattern of coliform bacteria detections in domestic wells in New Jersey. Examination of a statewide database of 10 years of water quality data from 93,447 samples, from 78,207 wells, generated ...

Bacteriological effects of hydraulically dredging polluted bottom sediment in the navigation channel of the Upper Mississippi River (river mile 827.5 [about 1,332 km] to 828.1 [about 1,333 km]) were investigated. Bottom sediment in the dredging site contained high total coliform densities (about 6,800 most-probable-number total coliform index per g [dry weight] and 3,800 membrane filter total c...

The purpose of this study was to determine the optimum membrane filter structure and characteristics for recovery of coliform organisms. Additionally, other factors such as sterilization method and membrane composition were examined. Fecal coliform growth tests with varied samples indicated that the most critical factor in recovery was surface pore morphology and not other factors previously su...

BACKGROUND The objective of this study was to evaluate the efficacy of Sanitization of Lettuce according to the protocols set forth by Iranian Ministry of Health and Medical Education for reducing populations of total coliform, fecal coliform, and helminth eggs present on lettuce. METHODS In the present study, we determined the load of total coliform, fecal coliform, and parasites of lettuce....

Fecal contamination of bedding has been associated with coliform mastitis caused by E. coli, while coliform mastitis caused by Klebsiella spp. is associated with wet sawdust and wood shavings.(1) Coliform mastitis has an average incidence rate of 15% to 20% in herds with low somatic cell counts (SCC) and is implicated in 30% to 40% of clinical cases. It is a common cause of fatal mastitis in ca...

Total and fecal coliform bacteria were isolated from the cloaca and feces of the estuarine diamondback terrapin. The majority of samples contained fecal coliforms. Escherichia coli was the predominant fecal coliform species isolated, and members of the genus Salmonella were isolated from 2 of 39 terrapins. Fecal coliform numbers are used to regulate shellfish harvests, and diamondback terrapins...

Criticism of journalists for creating confusion and needless anxiety is sometimes fully justified. On other occasions, at least part of the blame lays elsewhere. Consider the following. A headline in the Sunday Times on 14 May read: “Killer bug alert over organic vegetables.” The story continued “Tesco yesterday withdrew all organic mushrooms from its shelves after routine checks by environment...

Whether all members of the coliform group of bacteria should be accorded equal sanitary significance has been debated for at least a generation. English and German authorities are disposed to assign special significance to the presence of Escherichia coli, whereas it is the American practice, particularly as applied to water analyses, to consider all coliform bacteria of equal sanitary signific...
