Quick, cost-effective method to identify throat infections in offing

“The aim was to develop a rapid, accurate, sensitive, specific and cost-effective method for detection of S. pyogenes. The current methods of detection S. pyogenes infection are culture test, biochemical assays, polymerase chain reaction, genetic markers. And these methods are time consuming, expensive, are unable to pick up the bacteria if present in small numbers and may even wrongly identify other bacteria as S. pyogenes,” Professor Ashok Kumar from the Institute of Genomics and Integrative Biology, who led the research, told India Science Wire.

Based on this technique, he said, several other infection-causing microbes can be identified to prevent the disease by taking medical treatment at the early stage of infection.

The most common cause of throat infections in humans is S. pyogenes bacteria. If left untreated it may lead to damage of human heart valves resulting in a severe form of rheumatic heart disease. Early diagnosis can prevent damage of human heart valves by taking timely and correct medical care.

The team of researchers included Swati Singh and Ankur Kaushal from the CSIR-Institute of Genomics and Integrative Biology, Delhi, and Dr. Shashi Khare from the National Centre for Disease Control, Delhi.
