Workplace-related environmental exposure and its potential influence on hair mineral and gut microbiota in cloned working dogs.

ABSTRACT: Four genetically identical cloned dogs were produced from a single donor using the somatic cell nuclear transfer technique. They stayed in the same facility during youth period, and were later assigned to different locations according to their roles as working dogs. In this study, we report observations from four genetically identical cloned working dogs exposed to different environments, including an airport and a police station, for two years. Hair and fecal samples were collected to assess potential environmental influences on mineral content and intestinal microbiota composition. The concentrations of toxic minerals, such as Pb and Ni, were significantly higher in the hair mineral analysis of the dog exposed to the airport compared to those of the three police station-working dogs.
