Package Atmosphere Affects Postharvest Biology and Quality of Fresh-cut Cilantro Leaves

Autor: Yaguang Luo, Ji Gang Kim, Marian R. Wachtel, Yun Huang, James L. McEvoy

Publikováno v: HortScience. 39:567-570

Experiments were conducted to develop a modified atmosphere packaging system for fresh-cut cilantro (Coriandrum sativum L.) leaves, and to determine the effect of package film oxygen transmission rate (OTR) on package atmosphere and the consequence o

Evaluation of parameters affecting quantitative detection of Escherichia coli O157 in enriched water samples using immunomagnetic electrochemiluminescence

Autor: Daniel R. Shelton, Kenneth T. Belt, Marian R Wachtel, Jeffrey S. Karns, Jo Ann S. Van Kessel

Publikováno v: Journal of Microbiological Methods. 55:717-725

We report here the use of immunomagnetic (IM) electrochemiluminescence (ECL) for quantitative detection of Esherichia coli O157:H7 in water samples following enrichment in minimal lactose broth (MLB). IM beads prepared in-house with four commercial a

Cross-Contamination of Lettuce (Lactuca sativa L.) with Escherichia coli O157:H7 via Contaminated Ground Beef

Autor: Morse B. Solomon, Yaguang Luo, Anisha M. Williams-Campbell, James L. McEvoy, Marian R. Wachtel

Publikováno v: Journal of Food Protection. 66:1176-1183

A lettuce outbreak strain of E. coli O157:H7 was used to quantitate the pathogen's survival in ground beef and its transfer to hands, cutting board surfaces, and lettuce. Overnight storage of inoculated beef at 4 degrees C resulted in no pathogen gro

Cross-Contamination of Lettuce with Escherichia coli O157:H7

Autor: Amy O. Charkowski, Marian R. Wachtel

Publikováno v: Journal of Food Protection. 65:465-470

Contamination of produce by bacterial pathogens is an increasingly recognized problem. In March 1999, 72 patrons of a Nebraska restaurant were infected with enterohemorrhagic Escherichia coli (EHEC) O157:H7, and shredded iceberg lettuce was implicate

Prevalence of Escherichia coli Associated with a Cabbage Crop Inadvertently Irrigated with Partially Treated Sewage Wastewater

Autor: Robert E. Mandrell, Linda C. Whitehand, Marian R. Wachtel

Publikováno v: Journal of Food Protection. 65:471-475

Preharvest contamination of field crops may have many sources, including feces, soil, and irrigation water. In March 2000, a sewage spill released unchlorinated tertiary-treated effluent into a creek used to irrigate commercial produce. A field of yo

Association of Escherichia coli O157:H7 with Preharvest Leaf Lettuce upon Exposure to Contaminated Irrigation Water

Autor: Linda C. Whitehand, Marian R. Wachtel, Robert E. Mandrell

Publikováno v: Journal of Food Protection. 65:18-25

Recent foodborne outbreaks have linked infection by enterohemorrhagic Escherichia coli (EHEC) serotype O157:H7 to the consumption of contaminated lettuce. Contamination via food handler error and on-the-farm contamination are thought to be responsibl

Detection on Surfaces and in Caco-2 Cells of Campylobacter jejuni Cells Transformed with New gfp, yfp , and cfp Marker Plasmids

Autor: Sharon T. Horn, Maria T. Brandl, Marian R. Wachtel, William G. Miller, Anne H. Bates, Robert E. Mandrell

Publikováno v: Applied and Environmental Microbiology. 66:5426-5436

We have developed two sets of Campylobacter shuttle vectors containing either the gfp (green fluorescent protein), yfp (yellow fluorescent protein), or cfp (cyan fluorescent protein) reporter gene. In one set, the reporter gene is fused to a consensu

Decreased Adherence of Enterohemorrhagic Escherichia coli to HEp-2 Cells in the Presence of Antibodies That Recognize the C-Terminal Region of Intimin

Autor: Marian R. Wachtel, Lisa J. Gansheroff, Alison D. O'Brien

Publikováno v: Infection and Immunity. 67:6409-6417

Antiserum raised against intimin from enterohemorrhagic Escherichia coli (EHEC) O157:H7 strain 86-24 has been shown previously by our laboratory to inhibit adherence of this strain to HEp-2 cells. In the present study, we sought to identify the regio
