Evaluation Of Chromosomally-Integrated Luxcdabe And Plasmid-Borne Gfp Markers For The Study Of Localization And Shedding Of Stec O91:H21 In Calves, Yingying Hong
Masters Theses
Shiga toxin-producing Escherichia coli (STEC) has been recognized as an important foodborne pathogen. Of this group, O91 is one of the common serogroups frequently isolated from patients and food in some countries, with O91:H21 being previously implicated in hemolytic uremic syndrome (HUS). Cattle are principle reservoirs for STEC, and studies examining STEC shedding in cattle often include experimental inoculation of strains of interest using antibiotic resistance markers for identifiable recovery. However, indigenous fecal microbes exhibiting similar resistance patterns can confound such studies. Such was the case in a study by our group when attempting to characterize shedding patterns of O91:H21 …
