OBJECTIVE To analyze backcountry-area water quality in US Department of Agriculture Forest Service-designated wilderness areas for the presence of coliform and potentially pathogenic bacteria. METHODS Thirty-one backcountry lakes and streams were selected that would stratify the risk based on use by backpackers, pack animals, commercial grazing animals, or natural unaffected wilderness areas....

Malacca River water quality is affected due to rapid urbanization development. The present study applied LULC changes towards water quality detection in Malacca River. The method uses LULC, PCA, CCA, HCA, NHCA, and ANOVA. PCA confirmed DS, EC, salinity, turbidity, TSS, DO, BOD, COD, As, Hg, Zn, Fe, E. coli, and total coliform. CCA confirmed 14 variables into two variates; first variate involves...

Despite significant progress in the control of contagious pathogens, environmental mastitis continues to be a major cause of financial loss to the UK dairy industry. This paper presents some findings from a field study designed to investigate the incidence and significance of coliform infections acquired during the non-lactating period. The bacteriological status of two quarters from each of 62...

OBJECTIVE To compare an alternative method to the most probable number (MPN) test for the detection of total coliform present in manually expressed human milk. METHODS 343 samples of manually expressed human milk from flasks donated to the Human Milk Bank of Instituto Fernandes Figueira--IFF were sent to the Laboratory of Food Control of IFF. The samples were used for comparing both methods, ...

Hoyer, M.V., J.L. Donze, E.J. Schulz, D.J. Willis and D.E. Canfield, Jr. 2006. Total coliform and Escherichia coli counts in 99 Florida lakes with relations to some common limnological factors. Lake and Reserv. Manage. 22(2):141-150. The degree of bacterial contamination of 99 Florida lakes was studied using total coliform and Escherichia coli (E. coli) counts as indicators. Over 75% of the 405...

BACKGROUND Indiscriminate disposal of untreated wastes which are often heavily laden with sewage microorganisms some of which are pathogenic to humans into aquatic environments near cities could serve as potential dangers to human health. OBJECTIVE A prospective study was undertaken to investigate the scope of potential bacterial pathogens and to assess the extent of pollution of the Douala l...

Genetically feathered and featherless sibling broilers selected for matched BW were killed, scalded, and defeathered to determine the consequences of feathers and empty feather follicles on the recovery of bacteria from carcass breast skin. In trial 1, the vents of all carcasses were plugged and sutured before scalding to prevent the expulsion of cloacal contents during picking. In trial 2, hal...

The influence of volatile fatty acids on the ecology of the bacterial flora of the mouse intestinal tract has been studied in three situations where large fluctuations in the composition of the microflora have been observed. Young mice were shown to ingest solid food particles when 11 days old; this correlated with the appearance of strictly anaerobic fusiform bacilli in the intestinal lumen an...
