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...
BACKGROUND The aim of present work was to assess the concentration levels as well as vertical distribution of indicator bacteria including total coliform, fecal coliform, Pseudomonas aeruginosa, and Heterotrophic Plate Count (HPC) in the marine environment (seawater and coastal sediments) and evaluate the correlation between indicator bacteria and some physicochemical parameters of surface sedi...
We measured Escherichia coli, Enterococcus spp. and fecal coliform numbers in soil and on fresh potato skins after addition of solid dairy manure and dairy compost with and without alum (Al(2)(SO(4))(3)) treatment 1, 7, 14, 28, 179 and 297 days after application. The addition of dairy compost or solid dairy manure at rates to meet crop phosphorus uptake did not consistently increase E. coli and...
In the bacteriological testing of rural raw water supplies the laboratory is having to face, constantly, the problem of evaluating the sanitary significance of the atypical coliform bacteria so often recovered from positive tests. For several years the author and associates have carried on studies of these bacteria as a corollary to the water-testing service that is maintained for the rural pub...
This study evaluated the bacteria removal efficiency, re-suspension and survivability within two structural Best Management Practices (BMPs) called Vortechs installed at two different sites in Providence, Rhode Island. Twelve rain storms were sampled during years 2004 and 2005. Five pathogenic indicator bacteria, E. coli, enterococci, fecal streptococci, total coliform, fecal coliform, were ana...
Potential antimicrobial activity of follicular fluid and its selectivity remains open questions in field of human and animal reproduction. In our work we examine antimicrobial activity of porcine follicular fluid on coliform bacteria, as Gram-negative, and B. cereus, as Gram-positive, by incubation of different dilatations of bacteria with follicular fluid in cultivation medium and microbiologi...
Three different approaches for establishing guidelines for the microbiological quality of treated wastewater that is reused for agriculture are reviewed. These approaches have different objectives as their outcomes: the absence of faecal indicator organisms in the wastewater, the absence of a measurable excess of cases of enteric disease in the exposed population and a model-generated estimated...
a research was conducted at kauma oxidation ponds, a sewage water treatment plant found in lilongwe, malawi with an aim of establishing the efficiency of these sewage treatment ponds in treating sewage wastewater. water samples from the effluent discharging points in the maturation ponds were collected and analysed in the labouratory for, bod, coliform bacteria, total nitrogen (tn), phosphorous...
