| persistence and growth of the fecal indicator bacteria enterococci in detritus and natural estuarine plankton communities. | enterococci are used to evaluate recreational-water quality and health risks in marine environments. in addition to their occurrence in feces of warm blooded animals, they are also common epiphytes. we investigated the contribution of plankton- or particle-associated enterococci in estuarine and coastal water. seven water and size-fractionated plankton samples were collected monthly between april 2008 and january 2009 in the tidal reaches of the skidaway river (georgia, usa). each size fraction, ... | 2012 | 22327586 |
| geographic sharing of ribotype patterns in enterococcus faecalis for bacterial source tracking. | the limited host range of enterococcus faecalis may reduce its clonal diversity and thereby increase its geographic sharing of ribotype patterns. such sharing would be advantageous for bacterial source tracking (bst). we determined the geographic sharing of ribotype patterns in 752 ent. faecalis isolates obtained primarily from wastewater treatment plants in delaware (15 locations; 490 isolates), georgia (2 locations; 48 isolates), idaho (1 location; 118 isolates), new york (2 locations; 48 isol ... | 2007 | 17878566 |
| targeted sampling protocol as prelude to bacterial source tracking with enterococcus faecalis. | recent studies suggest that host origin databases for bacterial source tracking (bst) must contain a large number of isolates because bacterial subspecies change with geography and time. a new targeted sampling protocol was developed as a prelude to bst to minimize these changes. the research was conducted on the sapelo river, a tidal river on the georgia coast. a general sampling of the river showed fecal enterococcal numbers ranging from <10 (below the limit of detection) to 990 colony-forming ... | 2003 | 14674555 |
| salmonellae in the environment around a chicken processing plant. | studies have been conducted over a 2-year period to determine the extent to which a poultry processing plant served as a reservoir of salmonellae reaching the external environment, to examine the question of the importance of salmonellae in the environment, and to consider how best to control the spread of the organisms. the studies have been undertaken at a chicken processing plant handling between 75,000 and 80,000 birds per day. populations of salmonellae and indicator bacteria were estimated ... | 1974 | 4208511 |
| effect of growth promotant usage on enterococci species on a poultry farm. | the species population of enterococci isolated from four poultry houses for six grow-outs on one farm was determined. two houses on the farm were control houses and did not use any antimicrobials, while two other houses on the farm used flavomycin, virginiamycin, and bacitracin during different poultry grow-outs. litter, chick boxliners, feed, and poultry carcass rinses were obtained from each house and cultured for the presence of enterococci. nine species of enterococci (enterococcusfaecalis, ... | 2005 | 16252488 |
