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...
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...
in this survey, resistance to albendazole was investigated in 15 sheep flocks from different regions of khozestan province. on each flock, two groups of 15 sheep including control groups (untreated) and albendazole group (treated with 5 mg/kg of albendazole) were selected and the investigation was carried out using faecal egg count reduction test(f.e.c.r.t) for 10 days after treatment.posttreat...

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...
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...
OBJECTIVES To estimate exposure to faecal contamination through drinking water as indicated by levels of Escherichia coli (E. coli) or thermotolerant coliform (TTC) in water sources. METHODS We estimated coverage of different types of drinking water source based on household surveys and censuses using multilevel modelling. Coverage data were combined with water quality studies that assessed E...
Prevalence of indicator bacteria such as Escherichia coli and pathogenic bacteria like Vibrio Cholerae, Vibrio Parahaemolyticus and Salmonella were analysed in Vembanadu lake (9035'n 76025'e), along the west coast of India for a period of one year (October 20042005 September). Estuarine water samples were taken monthly from ten stations on the southern (inside bund region) and northern sides (o...
