| an outbreak of multidrug-resistant salmonella enterica serotype oranienburg in michigan dairy calves. | the objectives of this study were to report an outbreak of highly drug-resistant salmonella enterica serotype oranienburg in dairy calves, and conduct an epidemiological investigation of oranienburg identified on a dairy herd during a study to determine whether discontinuing feeding medicated milk replacer to preweaned dairy calves resulted in increased antimicrobial susceptibility in enteric bacteria. calf fecal samples and swabs of calf and maternity pens were collected monthly over 18 months. ... | 2010 | 20939741 |
| bacterial pathogen gene abundance and relation to recreational water quality at seven great lakes beaches. | quantitative assessment of bacterial pathogens, their geographic variability, and distribution in various matrices at great lakes beaches are limited. quantitative pcr (qpcr) was used to test for genes from e. coli o157:h7 (eaeo157), shiga-toxin producing e. coli (stx2), campylobacter jejuni (mapa), shigella spp. (ipah), and a salmonella enterica-specific (se) dna sequence at seven great lakes beaches, in algae, water, and sediment. overall, detection frequencies were mapa>stx2>ipah>se>eaeo157. ... | 2014 | 25423586 |
| multistate outbreak of salmonella serotype bovismorbificans infections associated with hummus and tahini--united states, 2011. | on september 27, 2011, three clinical isolates of salmonella enterica serotype bovismorbificans with indistinguishable pulsed-field gel electrophoresis (pfge) patterns were identified by the district of columbia public health laboratory (phl). human infection with s. bovismorbificans is rare in the united states. through query of pulsenet, the national molecular subtyping network for foodborne disease surveillance, six additional cases with indistinguishable pfge patterns were identified in thre ... | 2012 | 23169315 |
| nosocomial outbreak of a novel extended-spectrum β-lactamase salmonella enterica serotype isangi among surgical patients. | objective nosocomial outbreaks caused by salmonella are rare. we describe the investigation and control of a cluster of novel extended-spectrum β-lactamase (esbl) salmonella enterica serotype isangi in a hospital in southeastern michigan. methods an epidemiologic investigation, including case-control study, assessment of infection control practices and environmental cultures, was performed to identify modes of transmission. healthcare workers (hcws) exposed to case patients were screened. strain ... | 2016 | 27108715 |
