  • Knowledge gaps remain regarding the relationship of strain types and the shedding dynamics of STEC O157 by beef cattle that could be further clarified through the use of whole-genome sequencing. (frontiersin.org)
  • Shedding of STEC O157 by beef cattle has been described both in feedlot and pasture based settings ( 13 ), with variation in prevalence estimates between herds and between regions ( 10 , 14 , 15 ). (frontiersin.org)
  • STEC O157
  • Previously, the shedding dynamics and molecular diversity, through the use of multilocus variable number of tandem repeat analysis (MLVA) of STEC O157, were separately investigated in an Australian beef herd over a 9-month study period. (frontiersin.org)
  • A total of 33 ill persons infected with the outbreak strain of STEC O157:H7 were reported from five states. (cdc.gov)
  • PFGE
  • Public health investigators used DNA "fingerprints" of E. coli bacteria obtained through diagnostic testing with pulsed-field gel electrophoresis, or PFGE, to identify cases of illness that were part of this outbreak. (cdc.gov)
