CYP27A1 and abscess: In addition, other important human E. coli clones involved in ESBL dissemination were identified amongst CTX-M-producers such as ST10 in four dog isolates, three CTX-M-14 and one CTX-M-15 producers, all phylogroup A, obtained from wound, urine (n = 2) and tissue biopsy; ST167 in one CTX-M-15 and two CTX-M-55 dog isolates from wound, feces and urine, and also one equine CTX-M-15 producing horse isolate obtained from a wound swab; ST648 (phylogroup D) was identified in one isolate obtained from an interdigital abscess from a dog.
