Cepheid announces fresh TB test for use in developing countries The Sunnyvale, Calif.-based company Cepheid on Tuesday announced it has developed an instant diagnostic test for tuberculosis that it’ll sell at a reduced cost in growing countries, the SAN FRANCISCO BAY AREA Chronicle reports. The check was developed in partnership with the Foundation for LATEST Diagnostics, the University of Medication and Dentistry of New Jersey, and the National Institute of Infectious and Allergy Diseases. Based on the Chronicle, the test detects DNA sequences that are exclusive to TB bacteria.According to Dr. William Schaffner, a professor of preventive medication and infectious illnesses at Vanderbilt University INFIRMARY in Nashville, Tennessee, such actions are extreme and may be indicative of something more serious compared to the press is reporting. ‘We have cases of bubonic plague every once in awhile in the usa, plus they don’t require this type of public wellness response,’ he stated to Fox News. ‘Personally i think there’s something here that we don’t know, because this seems an extremely expansive response to just one case.’ What the real threat could be, however, remains unidentified. It is possible that officials are merely being extra wary of the disease’s spread, as China’s background is blighted with several main outbreaks of the plague.
