Cytomegalovirus (CMV) Infection Can Be Detected Using Saliva In NewBorns!
A group of researchers from the University of Alabama at Birmingham (UAB) have come up with a new way of detecting the presence of cytomegalovirus (CMV) infection in the newborns which is one of the causes of hearing loss in children by collecting saliva samples from them.
It was found that all babies born with CMV infection were identified through their liquid saliva samples and the dry saliva samples helped in identifying the infection in 97.4% of the newborns.
Because babies developing CMV infection are asymptomatic, diagnostic tests to detect the presence of infection are very important. Once a baby tests positive, he/she can be continuously monitored and required treatment can be provided to prevent hearing loss.
The study involved about 35,000 newborns all born between June 2008 and November 2009. Saliva samples were taken from them when they were roughly 1 day old. The screening of samples was conducted using RT-PCR (real time polymerase chain reaction) and rapid culture methods.
