  • Deer sausage: a newly identified vehicle of transmission of Escherichia Coli O157:H7.
    The Journal of pediatrics, 2009
    Co-Authors: Christina K. Ahn, Anthony J. Russo, Karla R. Howell, Nicholas J. Holt, Patricia Sellenriek, Robert J. Rothbaum, Anne M. Beck, Leon J. Luebbering, Phillip I. Tarr
    Abstract:

    Five Missouri patients infected with Escherichia Coli O157:H7 were studied for an epidemiologically plausible association. Case isolates, case interviews, and pathogen and meat XbaI pulsed field electrophoresis patterns were consistent with the common source being contaminated, fermented deer sausage, a previously unrecognized mode of transmission for Escherichia Coli O157:H7.

  • Escherichia Coli O157:H7 : Specific Pathogens
    Gastroenterology Clinics of North America, 2001
    Co-Authors: Phillip I. Tarr, Marguerite A. Neill
    Abstract:

    Escherichia Coli O157:H7 can cause severe epidemic, sporadic, and human diseases. Humans of all ages can be infected, and gastroenterologists frequently are involved in the management of such patients. Antibiotics, antimotility agents, and opioid narcotics should be avoided, and infected patients should be reported to the appropriate public health officers as a matter of urgency.

  • Escherichia Coli O157: H7: Overview of Clinical and Epidemiological Issues.
    Journal of food protection, 1994
    Co-Authors: Phillip I. Tarr
    Abstract:

    Escherichia Coli O157:H7 is an important and common human pathogen which causes diarrhea, bloody diarrhea (hemorrhagic Colitis) and the life threatening post-diarrheal disorder, hemolytic uremic syndrome (HUS). Escherichia Coli O157:H7 produces one or two potent cytotoxins, designated Shiga-like toxins (or verocytotoxins) I and II. While additional serotypes of cytotoxin-producing E. Coli may cause human disease, E. Coli O157:H7 is the most important such enteric pathogen in the United States. Epidemiologic data suggest that the incidence of hemolytic uremic syndrome is probably increasing. Until data emerge from controlled studies, conservative management of infected patients remains the mainstay of therapy, rather than specific antibacterial or antitoxin therapy. The serious nature of illness caused by E. Coli O157:H7 should make prevention of human infection with this pathogen a high priority for the food industry.

  • Bacterial ileocecitis caused by Escherichia Coli O157:H7.
    Journal of pediatric gastroenterology and nutrition, 1992
    Co-Authors: Phillip I. Tarr, Edward Weinberger, Edwin I. Hatch, Dennis L. Christie
    Abstract:

    Escherichia Coli O157:H7 is most commonly linked to hemorrhagic Colitis and the hemolytic uremic syndrome. Diagnostic ultrasound was used to demonstrate terminal ileum abnormalities suggestive of bacterial ileocecitis, a recently described entity that resembles acute appendicitis, in a patient whose stool culture yielded E. Coli O157:H7. This case extends the spectrum of disease caused by E. Coli O157:H7 and expands the number of organisms that can cause bacterial ileocecitis.

  • Isolation of Shiga-like toxin producing Escherichia Coli (O157 and non-O157) in a community hospital.
    Diagnostic microbiology and infectious disease, 1996
    Co-Authors: Choong H. Park, Kirsten M. Gates, Nancy M. Vandel, Deborah L. Hixon
    Abstract:

    During a 25-week period (June to November 1995), stool specimens with an abnormal appearance (semiliquid to liquid, containing gross mucus or blood) were selected for testing with a new EIA method for detection of Shiga-like toxin-producing Escherichia Coli (O157:H7 and non-O157 serotypes). The 270 specimens tested originated from different patients. Eleven of the 270 were positive by EIA for Shiga-like toxin (SLT). Escherichia Coli O157:H7 was recovered from six of the EIA-positive specimens, and the remaining five positive samples produced non-O157 isolates.

  • Variations of Escherichia Coli O157:H7 Survival in Purple Soils
    International journal of environmental research and public health, 2017
    Co-Authors: Taoxiang Zhang, Wenhao Yang
    Abstract:

    Escherichia Coli O157:H7 is a well-recognized cause of human illness. Survival of Escherichia Coli O157:H7 in five purple soils from Sichuan Province was investigated. The dynamics of E. Coli O157:H7 survival in purple soils were described by the Weibull model. Results showed that this model is suitable to fit survival curves of E. Coli O157:H7 in purple soils, with the calculated td value (survival time needed to reach the detection limit of 100 CFU·g−1) ranging from 2.99 days to 26.36 days. The longest survival time of E. Coli O157:H7 was observed in neutral purple soils (24.49 days), followed by alkalescent purple soil (18.62 days) and acid purple soil (3.48 days). The redundancy analysis (RDA) revealed that td values were significantly enhanced by soil nutrition (total organic carbon (OC), total nitrogen (TN), available potassium (AK) and the ratio of humic acid to fulvic acid (Ha/Fa)), but were significantly suppressed by iron and aluminum oxide.
