AMD in Action: Fighting Infectious Disease on Many Fronts
With the largest Ebola outbreak in history raging through West Africa, understanding whether the virus is changing as it spreads through different populations can help responders know what treatments to use and also help research laboratories develop new tools to speed diagnosis in the field.
The diagnosis of a drug-resistant “nightmare bacteria” in two Colorado patients spurred hospital and state health officials to join forces with CDC to investigate. These bacteria — Carpabenem-resistant Enterobacteriaceae, or CRE — have become resistant to all or nearly all of the antibiotics we have today. Untreatable and hard-to-treat infections from CRE germs are on the rise among patients in medical facilities.
Scientists traced a hepatitis A outbreak affecting 162 people to a berry blend product. Whole genome sequencing and advanced analytic methods helped them identify a shipment of pomegranate seeds from Turkey as the source of the outbreak.
In routine food testing, the Canadian Food Inspection Agency found Listeria in bagged lettuce. Investigators conducted whole genome sequencing and found one of the closest matches between an infected person and a contaminated food product that they had ever seen.
When polio broke out in the Horn of Africa in 2013, Kenya lab technicians quickly identified the source as a wild virus and sent specimens to CDC. Overnight, CDC scientists sequenced the virus and identified it as coming from Nigeria—on the other side of the continent.
In early May 2014, CDC received a mucus specimen from a MERS patient. In less than 48 hours, CDC used Advanced Molecular Detection (AMD) methods to sequence the complete virus genome.
