  1. Factors associated with fecal shedding of verotoxin-producing Escherichia coli O157 on dairy farms.

    Article - En anglais

    Fecal samples were collected from 4,361 dairy cows on 91 dairy operations between 26 February and 8 July 1996.

    Fecal samples were cultured for Escherichia coli 0157, and positive isolates were probed for verotoxin-producing genes.

    A total of 52 (1.2%) fecal samples on 22 (24.2%) operations were positive for verotoxin-producing E. coli 0157.

    Herds in which samples were collected on or after 1 May 1996 were significantly more likely to test positive than herds sampled before that date (odds ratio=7.7).

    Herds maintained on farms on which alleyways were flushed with water to remove manure were 8.0 times more likely to have samples test positive for verotoxin-producing E. coli 0157 than were herds maintained on farms cleaned by use of other methods of manure removal.
