MDT Molecular Diagnostic Testing has provided a testing service for veterinary surgeons and the pig and poultry industries. Based at Craven Arms in Shropshire, England, it uses the polymerase chain reaction method to detect DNA and RNA in bacteria and viruses from a variety of tissues.

According to the company, the new tests offered by MDT can detect non-viable micro-organisms from tissue, throat swabs, blood and feces that may not have shown up in previous tests and distinguish different groups and strains of bacteria.
