The main risks of cyclophosphamide therapy include hematological disorders, infertility, hemorrhagic cystitis and malignancies. Gastrointestinal side effects reported to date are often non-specific and not severe. We present the first case of a fatal small bowel enteritis and pan-colitis which appears to be associated with cyclophosphamide. We aim to raise the readers' awareness of this significant adverse event to facilitate clinical suspicion and early recognition in potential future cases.展开更多
An endemic multi-drug resistant ST117 E. coil isolate coproducing MCR-I and 3 ESBL loci was, for the first time, detected from diseased chicken, Liaoning Province, in Northeast China, from 2011 to 2012.

Whole- genome sequencing revealed 5 unique plasmids, namely pHXH-1, pHXH-2, pHXH-3, pHXH-4 and pHXH- 5）. Among them, pHXHI and pHXH4 encode ESBL, and pHXH-5 mediates MCR-1 colistin resistance. The results indicate that the potentially-national dissemination of MCR-l-positive pathogens with pan-drug resistance proceeds via food chains.展开更多
