Real-time PCR was applied to quantify the abundance of human adenoviruses in two southern California urban rivers, the San Gabriel and Los Angeles. A total of 114 river samples from five different locations were collected over a 1-year period and analyzed for human adenoviruses, along with fecal indicator bacteria and coliphages. Adenoviruses were detected by real-time PCR in approximately 16% ...

Predicting the presence of enteric viruses in surface waters is a complex modeling problem. Multiple water quality parameters that indicate the presence of human fecal material, the load of fecal material, and the amount of time fecal material has been in the environment are needed. This paper presents the results of a multiyear study of raw-water quality at the inlet of a potable-water plant t...

This study aims to assess the quality of drinking water in Karbala. Furthermore, tap and bottled are compared this study. Materials method: Physical, chemical, bacteriological parameters were all measured The test includes a total count coliform fecal coliform, which may be detected using standard microbiology procedures. Results: In water, dissolved salts (TDS), Ca, Cl, Mg within acceptable ra...

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 accuracy of transcutaneous bilirubin (TcB) measurements obtained with a Bilicheck device in 70 preterm neonates before phototherapy and during phototherapy from the exposed and unexposed skin of the forehead (under the eye patch) was evaluated by comparing the TcB with the total serum bilirubin (TSB) that was performed within +/- 30 minutes of the TcB measurements. The correlation and propo...

this study focused on use of bacterial extracellular enzyme activities as biochemical parameters, along with the microbiological and physicochemical characteristics, in a comprehensive assessment of water quality of four lake ecosystems in the province of vojvodina (northern serbia): provala, ludas, zobnatica and palic. water samples were collected in june and october, 2008. for assessment of ...

BACKGROUND Neonatal hyperbilirubinemia, especially kernicterus, can be prevented by screening for neonatal jaundice. The transcutaneous bilirubin (TcB) meter is a non-invasive medical device for screening neonates. The study aimed to investigate the validity of a TcB meter in a resource-limited setting such as Mongolia. METHODS Term and late preterm neonates from the National Center for Mater...

The traditional membrane filter (American Public Health Association, Standard Methods for the Examination of Water and Wastewater, 16th ed., American Public Health Association, Washington, D.C., 1985) and presence-absence (P-A) (J. A. Clark, Can. J. Microbiol. 14:13-18, 1968) techniques for the detection of coliform bacteria were compared in a small nonchlorinated drinking water distribution sy...
