| epidemiologic survey of sylvatic plague by serotesting coyote sentinels with enzyme immunoassay. | the geographic distribution and areas of high sylvatic plague activity in california were verified by using coyotes (canis latrans) as sentinel animals. antibody levels against yersinia pestis were tested using the enzyme-labelled antibody (ela) test and the microtiter passive hemagglutination and hemagglutination inhibition. a survey using the ela test indicated that the overall antibody prevalence among 143 coyotes was 21%. by geographic regions, the highest antibody prevalence was 27% among c ... | 1979 | 382839 |
| surveillance of sylvatic plaque in oregon by serotesting carnivores. | in oregon, during 1974-1979, 10.3 per cent of 3.255 statewide blood samples from carnivores were positive for yersinia pestis. the per cent positive rate and geometric mean positive titer increase monthly from january (6.5 per cent) to june (21.7 per cent), and decline thereafter. data are presented on how geographic location, species, and time of year affect surveillance results. the correlation of carnivore plague surveillance with human cases in discussed. | 1982 | 7125037 |
| an overview of plague in the united states and a report of investigations of two human cases in kern county, california, 1995. | plague was confirmed in the united states from nine western states during 1995. evidence of yersinia pestis infection was identified in 28 species of wild or domestic mammals. thirteen of the plague positive species were wild rodents; 15 were predators/carnivores. yersinia pestis was isolated from eight species of fleas. seven confirmed cases of human plague were reported in 1995 (new mexico 3; california 2; arizona and oregon 1 each). five of the seven cases were bubonic; one was septicemic and ... | 1997 | 9221742 |
| multiple antimicrobial resistance in plague: an emerging public health risk. | antimicrobial resistance in yersinia pestis is rare, yet constitutes a significant international public health and biodefense threat. in 1995, the first multidrug resistant (mdr) isolate of y. pestis (strain ip275) was identified, and was shown to contain a self-transmissible plasmid (pip1202) that conferred resistance to many of the antimicrobials recommended for plague treatment and prophylaxis. comparative analysis of the dna sequence of y. pestis plasmid pip1202 revealed a near identical inc ... | 2007 | 17375195 |
| reactive arthritis following culture-confirmed infections with bacterial enteric pathogens in minnesota and oregon: a population-based study. | to describe the epidemiology and clinical spectrum of reactive arthritis (rea) following culture-confirmed infection with bacterial enteric pathogens in a population-based study in the usa. | 2008 | 18272671 |
| ocular plague (yersinia pestis) in mule deer (odocoileus hemionus) from wyoming and oregon. | although plague is relatively rare in wild ungulates, this report describes ocular lesions associated with yersinia pestis infection in three free-ranging mule deer (odocoileus hemionus) from wyoming and oregon, usa. all deer were observed antemortem and seemed to be blind. post-mortem examination revealed gross lesions of bilateral keratoconjunctivitis and/or panophthalmitis in the first two deer, but only partial retinal detachment in the third deer. microscopically, all deer had moderate-to-s ... | 2008 | 18957655 |
| notes from the field: two cases of human plague--oregon, 2010. | plague, caused by yersinia pestis, is enzootic among rodents in the western united states. humans can be infected through 1) the bite of an infected flea carried by a rodent or, rarely, other animals, 2) direct contact with contaminated tissues, or 3) in rare cases, inhalation of respiratory secretions from infected persons or animals. in september 2010, the oregon health authority reported the first two cases of human plague in oregon since 1995 and the only two u.s. cases in 2010. | 2011 | 21346709 |
| incidence of foodborne illnesses reported by the foodborne diseases active surveillance network (foodnet)-1997. foodnet working group. | in 1997, the foodborne diseases active surveillance program (foodnet) conducted active surveillance for culture-confirmed cases of campylobacter, escherichia coli o157, listeria, salmonella, shigella, vibrio, yersinia, cyclospora, and cryptosporidium in five emerging infections program sites. foodnet is a collaborative effort of the centers for disease control and prevention's national center for infectious diseases, the united states department of agriculture's food safety and inspection servic ... | 2000 | 10852576 |
| phenotypic and phylogenetic characterization of ruminal tannin-tolerant bacteria. | the 16s rrna sequences and selected phenotypic characteristics were determined for six recently isolated bacteria that can tolerate high levels of hydrolyzable and condensed tannins. bacteria were isolated from the ruminal contents of animals in different geographic locations, including sardinian sheep (ovis aries), honduran and colombian goats (capra hircus), white-tail deer (odocoileus virginianus) from upstate new york, and rocky mountain elk (cervus elaphus nelsoni) from oregon. nearly compl ... | 1998 | 9758806 |
| bacteria associated with crabs from cold waters with emphasis on the occurrence of potential human pathogens. | a diverse array of bacterial species, including several potential human pathogens, was isolated from edible crabs collected in cold waters. crabs collected near kodiak island, alaska, contained higher levels of bacteria than crabs collected away from regions of human habitation. the bacteria associated with the crabs collected near kodiak included yersinia enterocolitica, klebsiella pneumoniae, and coagulase-negative staphylococcus species; the pathogenicity of these isolates was demonstrated in ... | 1984 | 6742824 |
