multiyear study of sludge application to farmland: prevalence of bacterial enteric pathogens and antibody status of farm families.we describe our experience with the isolation of salmonellae from sewage sludge from four treatment plants in different geographic areas of ohio. over 3 years, we isolated salmonellae 50 times from 311 sludge samples. most isolations were made after enrichment in selenite broth (bbl microbiology systems, cockeysville, md.). the largest proportion of isolations came from the plant serving the population of columbus, a large metropolitan area. a significantly greater number of isolations from this ...19873606093
incidence of campylobacter jejuni in fresh eviscerated whole market chickens. 19817296414
fecal shedding and antimicrobial susceptibility of selected bacterial pathogens and a survey of intestinal parasites in free-living waterfowl residing in metropolitan parks in central ohio were surveyed for the fecal shedding and antimicrobial susceptibility patterns of campylobacter jejuni, escherichia coli, salmonella spp., and pasteurella multocida. in addition, a survey for intestinal parasites was also conducted in these same waterfowl to determine parasite burdens in free-living waterfowl. prevalences of 67%, 50%, and 0.2% of e. coli, c. jejuni, and salmonella spp., respectively, were observed for all water ...200111332473
detection and survival of campylobacter in chicken eggs.campylobacter jejuni, a food-borne human pathogen, is widespread in poultry; however, the sources of infection and modes of transmission of this organism on chicken farms are not well understood. the objective of this study was to determine if vertical transmission of c. jejuni occurs via eggs.200314633036
cryptosporidiosis: a brief literature review and update regarding cryptosporidium in feces of canada geese (branta canadensis).canada geese are increasingly abundant in ohio, with large nesting populations throughout the state, and goose feces contaminate grassy areas and pavements in many public, commercial, and residential sites. in 1999 the authors found a high prevalence of giardia, campylobacter, and especially cryptosporidium in collected feces of canada geese. the purpose of this follow-up study was to survey known canada geese sites in three counties in ohio (lucas, ottawa, and wood) and to determine the prevale ...200415032111
gastroenteritis in us marines during operation iraqi freedom.approximately 83,000 us marines participated in the opening phase of operation iraqi freedom in spring 2003. a navy preventive medicine laboratory was set up in ad diwaniyah, iraq, to provide clinical diagnostic support for marine medical units during a period of repositioning in south-central iraq.200515712073
a waterborne outbreak of gastroenteritis with multiple etiologies among resort island visitors and residents: ohio, 2004.the implementation of treated municipal water systems in the 20th century led to a dramatic decrease in waterborne disease in the united states. however, communities with deficient water systems still experience waterborne outbreaks. in august 2004, we investigated an outbreak of gastroenteritis on south bass island, ohio, an island of 900 residents that is visited by >500,000 persons each year.200717243052
prevalence and antimicrobial resistance profile of campylobacter spp. isolated from conventional and antimicrobial-free swine production systems from different u.s. regions.we conducted a study to compare the prevalence and antimicrobial resistance profile of campylobacter isolated from 34 farm-slaughter pair cohorts of pigs raised in conventional and antimicrobial-free (abf) production systems. isolates originated from four different states of two geographic regions (region 1--ohio and michigan; region 2--wisconsin and iowa). a total of 838 fecal and 1173 carcass samples were examined. campylobacter isolates were speciated using multiplex polymerase chain reaction ...201021133777
