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...

The present study was designed to perform a long term observation on the bacterial excretion in human feces with special reference to Escherichia coli and Clostridium welchii. Fourteen children and 6 adult employees were chosen from 2 isolated institutions where mentally retarded child inmates were dwelling. One institution (K) has had several epidemics of dysentery in the past 5 years, whereas...

Samples from the duodenum, jejunum, and ileum, as well as from the cecum and colon, were obtained from 11 mature grass-fed horses. Viable counts of total culturable and proteolytic bacteria were made on habitat-simulating media containing 40% clarified ruminal fluid. The mean pHs in the duodenum, jejunum, and ileum were 6.32, 7.10, and 7.47, respectively; the mean pH decreased to 6.7 in the hin...

The bacterial eggshell contamination of shell eggs in different commercial housing systems; two conventional cages, one organic aviary system and one barn production, were compared. The total counts of aerobic bacteria and the total counts of Gramnegative bacteria on the shell were used to detect key points where contamination occurred and to study the progress of contamination in the egg handl...

background: in recent years, many studies have been conducted on finding a suitable replacement for fish meal to supply the needs of aquaculture feed industry. objectives: the present study was performed to examine the effect of replacing fish meal and fish oil with plant sources on bacterial counts in intestinal contents and mucus and bacterial composition in beluga sturgeon. methods: beluga s...

Pseudomonas aeruginosa is one of the most common causes of keratitis. The current study was done to evaluate the therapeutic effects of antibacterial combinations with Silver nanoparticles (Ag-NPs) and Ciprofloxacin in experimental Pseudomonas keratitis. Sixty four New Zealand rabbits were prepared. All rabbits were randomly categorized into eight groups (each group containing eight rabbits): C...

Total direct counts of bacterial abundance are central in assessing the biomass and bacteriological quality of water in ecological and industrial applications. Several factors have been identified that contribute to the variability in bacterial abundance counts when using fluorescent microscopy, the most significant of which is retaining an adequate number of cells per filter to ensure an accep...
