| 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 |
| metagenomics of two severe foodborne outbreaks provides diagnostic signatures and signs of coinfection not attainable by traditional methods. | diagnostic testing for foodborne pathogens relies on culture-based techniques that are not rapid enough for real-time disease surveillance and do not give a quantitative picture of pathogen abundance or the response of the natural microbiome. powerful sequence-based culture-independent approaches, such as shotgun metagenomics, could sidestep these limitations and potentially reveal a pathogen-specific signature on the microbiome that would have implications not only for diagnostics but also for ... | 2017 | 27881416 |
| prevalence of shiga toxin-producing escherichia coli and salmonella enterica in rock pigeons captured in fort collins, colorado. | the potential role of rock pigeons (columba livia) in the epidemiology of shiga toxin-producing escherichia coli (stec) and salmonella enterica is unclear. our objective was to determine the prevalence of stec and s. enterica in pigeons at urban and dairy settings as a function of season. prevalence of stec and s. enterica was estimated by bacteriologic culture of cloacal swabs collected from pigeons trapped at urban and dairy locations in and around fort collins, colorado from january to novemb ... | 2006 | 16699148 |
| multistate outbreak of salmonella typhimurium infections associated with eating ground beef--united states, 2004. | salmonella infections cause an estimated 1.4 million human illnesses and 400 deaths annually in the united states. although the incidence of several other foodborne bacterial infections decreased substantially during 1996-2004, the incidence of salmonella infections declined modestly. in september 2004, the new mexico department of health received reports from the new mexico scientific laboratory division of eight salmonella enterica serotype typhimurium isolates that had indistinguishable pulse ... | 2006 | 16498383 |
| occurrence of salmonella enterica serotype typhimurium dt104a in retail ground beef. | surveillance data of cattle and human isolates of salmonella enterica serovar typhimurium dt104 indicate that this pathogen emerged worldwide in the 1980s, particularly in cattle. studies were conducted to determine the prevalence of salmonella typhimurium dt104 in ground beef. samples were also tested for the presence of generic escherichia coli. a total of 404 fresh ground beef samples obtained at retail stores from new york, san francisco, philadelphia, denver, atlanta, houston, and chicago w ... | 2002 | 11848574 |

| perceptions regarding workplace hazards at a veterinary teaching hospital. | objective: to assess perceptions of personnel working at a veterinary teaching hospital regarding risks of occupational hazards and compare those perceptions with assessments made by occupational safety experts. | 2010 | 20590501 |
| environmental salmonella in agricultural fair poultry exhibits in colorado. | salmonella enterica is a common zoonotic pathogen in humans. transmission typically occurs through consumption of contaminated food products or contact with infected animals, including poultry or their environment. the objective of this study was to estimate the frequency of salmonella contamination in the environment in poultry exhibits at agricultural fairs. samples were collected from cages, feed, floors and tables in the exhibit and cultured for salmonella. at least one environmental sample ... | 2014 | 23773691 |
