salmonella dublin as a cause of diarrhea and abortion in ewes. 19704918902
salmonella serotype montevideo infections associated with chicks--idaho, washington, and oregon, spring 1995 and 1996.during 1995 and 1996, public health laboratories in idaho, washington, and oregon identified clusters of infections with salmonella serotype montevideo. epidemiologic investigations, including enhanced surveillance, of these clusters indicated association with exposure to chicks. this report summarizes the findings of these investigations, which suggest that handling chicks is a health risk, especially for children; consequently thorough handwashing is recommended after handling of chicks.19979082177

a comparative assessment of boise, idaho, ambient air fine particle samples using the plate and microsuspension salmonella mutagenicity assays.the primary objective of this study is to characterize the genotoxic potential of the ambient air aerosols collected within an air shed impacted primarily by wood smoke and automotive emissions. the study also examines the relative merits of a microsuspension assay and the standard plate assay for monitoring the presence of airborne particle-bound mutagens. wintertime ambient air particulate samples collected from boise, idaho, usa, were shown to contain extractable organic matter that is mutage ...200111482407
alfalfa seed decontamination in a salmonella outbreak.based on in vitro data, the u.s. food and drug administration recommends chemical disinfection of raw sprout seeds to reduce enteric pathogens contaminating the seed coats. however, little is known about the effectiveness of decontamination at preventing human disease. in 1999, an outbreak of salmonella enterica serotype mbandaka occurred in oregon, washington, idaho, and california. based on epidemiologic and pulsed-field gel electrophoresis evidence from 87 confirmed cases, the outbreak was li ...200312702229
mutation spectra in salmonella of complex mixtures: comparison of urban air to benzo[a]pyrene.we used an ion-exchange procedure coupled to the salmonella assay to fractionate the dichloromethane-extractable particulate organics from an urban air sample collected in boise, idaho. a resulting base/neutral fraction contained 81% of the mutagenic activity but only 36% of the mass of the unfractionated sample. chemical analysis showed that polycyclic aromatic hydrocarbons (pahs) accounted for much of the mutagenic activity of the air sample. colony probe hybridization, pcr, and dna sequence a ...19947851338
infectious agents associated with neonatal calf disease in southwestern idaho and eastern oregon.over a 2-year period, 296 episodes of disease involving 226 1-to-60-day-old calves were referred to the caldwell veterinary teaching center. infectious disease agents were found in 96% of the cases. salmonella spp were the most frequently isolated agents from dairy calves, whereas coronavirus was the agent most commonly associated with diarrhea in beef calves. multiple agents were found in 20% of the dairy calves and in 12% of the beef calves. salmonella dublin, which is associated with severe d ...19827085442
isolation of salmonella spp. from dead gulls (larus californicus and larus delawarensis) from an idaho irrigation reservoir.an epizootic of unknown etiology resulting in the death of about 500 sea gulls (larus californicus and larus delawarensis) in 24 hr occurred on an irrigation reservoir in southwestern idaho in april 1975. salmonella spp. were isolated from necropsy specimens from 2 of 6 gulls examined. no salmonella spp. were isolated from fecal specimens or dead gulls collected at a nesting site.1977334150
multistate outbreak of multidrug-resistant salmonella newport infections associated with ground beef, october to december 2007.in late october 2007, an outbreak of multidrug-resistant salmonella newport infections affected 42 case patients in california, arizona, idaho, and nevada. a case-control study implicated ground beef from one chain store. despite detailed ground beef purchase histories-including shopper card information for several case patients-traceback efforts by both the u.s. department of agriculture, food safety and inspection service and the california department of public health were unable to identify t ...201121819658
multidrug-resistant salmonella typhimurium in four animal facilities.in 1999 and 2000, 3 state health departments reported 4 outbreaks of gastrointestinal illness due to salmonella enterica serotype typhimurium in employees, clients, and client animals from 3 companion animal veterinary clinics and 1 animal shelter. more than 45 persons and companion animals became ill. four independent investigations resulted in the testing of 19 human samples and >200 animal samples; 18 persons and 36 animals were culture-positive for s. typhimurium. one outbreak was due to mul ...200516102313
feedstuffs as a vehicle of cattle exposure to escherichia coli o157:h7 and salmonella enterica.feed has been reported as a vehicle for transmission of salmonella enterica in cattle and several lines of evidence suggest that feed can be a vehicle for transmitting escherichia coli o157:h7 as well. to show whether microbial contamination of feeds could contribute to the populations of s. enterica and e. coli o157:h7 on a farm, we compared isolates from feed samples to bovine fecal isolates from the same farm using pulsed-field gel electrophoresis (pfge). four of 2365 component feed samples ( ...200312935747
outbreaks of multidrug-resistant salmonella typhimurium associated with veterinary facilities--idaho, minnesota, and washington, 1999.cdc received reports in 1999 from three state health departments of outbreaks of multidrug-resistant salmonella serotype typhimurium infections in employees and clients of small animal veterinary clinics and an animal shelter. salmonella infections usually are acquired by eating contaminated food; however, direct contact with infected animals, including dogs and cats, also can result in exposure and infection. this report summarizes clinical and epidemiologic data about these outbreaks and revie ...200111787576
