The collection of STEC isolates
A total of 56 STEC strains were gleaned from anal or carcass swabs of
cattle and sheep in Xinjiang Province from April 2016 to September 2018.
Among them, 27 bovine isolates were obtained from 5 different farms and
slaughterhouses in City of Yili, while 29 ovine isolates from 3 farms
and slaughterhouses in Cities of Changji and Korla. These isolates have
been shown to carry stx 1 and/or stx 2 by PCR genotyping
(Liu et al., 2020;
Zhang et al., 2018). E. colistrains were cultured in Luria-Bertani broth (BD, China) or MacConkey
Agar medium (AOBOX, Beijing, China).
