The survival of three foodborne pathogens (Listeria monocytogenes, Yersinia enterocolitica, and Salmonella) attached to mortar surfaces, with or without biological soil (porcine serum) and incubated at either 4 or 10 degrees C in the presence of condensate, was evaluated. Soiled and unsoiled coupons were inoculated by immersion into a five-strain cocktail… (More)
Samples from environmental sites and raw product in a chicken further processing plant were collected every 6 weeks for 12 months. Each sample site was examined before and after a complete production shift. All samples were examined for the presence of Listeria monocytogenes, which was detected in floor drains on the raw product side of the plant… (More)
Cryptosporidium parvum has been associated with outbreaks of human illness by consumption of contaminated water, fresh fruits, and vegetables. Free-living nematodes may play a role in pathogen transmission in the environment. Caenorhabditis elegans is a free-living soil nematode that has been extensively studied and serves as a good model to study possible… (More)
Transmissible colistin resistance in the form of an mcr-1-gene-bearing plasmid has been recently reported in Enterobacteriaceae in several parts of the world. We report here the completed genome sequence of an Escherichia coli strain isolated from swine in the United States that carried the mcr-1 gene on an IncI2-type plasmid.
Transmissible colistin resistance conferred by the mcr-1 gene-bearing IncI2 plasmid has been recently reported in Escherichia coli in the United States. We report here the completed genome sequence of a second E. coli strain isolated from swine in the United States that carried the mcr-1 gene on an IncI2-type plasmid.
Colistin is a reserved antimicrobial agent that is used to treat multidrug-resistant infections. Resistance to colistin is known to be innate among Gram-positive organisms and conferred by chromosomal modifications that alter the drug target in Gramnegative species. Liu et al. (1) recently described a gene, mcr-1, which codes for a phosphoethanolamine… (More)
Campylobacter jejuni clone SA is the major cause of sheep abortion and contributes significantly to foodborne illnesses in the United States. Clone SA is hypervirulent because of its distinct ability to produce systemic infection and its predominant role in clinical sheep abortion. Despite the importance of clone SA, little is known about its distribution… (More)
Campylobacter lari is frequently isolated from shore birds and can cause illness in humans. Here, we report the draft whole-genome sequence of a urease-positive strain of C. lari that was isolated in estuarial water on the coast of Delaware, USA.
Cyclospora cayetanensis infection continues to be a major cause of diarrhea particularly in immunosuppressed patients. The emergence of new related parasite pathogens, is an issue of public health concern. We report here a case where a Cyclospora-like organism was the cause of diarrhea in an immunocompetent patient from Venezuela.
