Quigley Anti-Viral Compound QR448(a) Successfully Prevents Transmission of Infectious Bronchitis i...( DOYLESTOWN Pa. Sept. 16 /- The Qu...),Health

DOYLESTOWN, Pa., Sept. 16 /PRNewswire-FirstCall/ -- The Quigley Corporation (Nasdaq: QGLY), http://www.quigleyco.com, announced positive results from a follow up study conducted by its wholly owned subsidiary, Quigley Pharma, http://www.QuigleyPharma.com, designed to examine the ability of its veterinary anti-viral compound QR448(a) to prevent the transmission of Infectious Bronchitis Virus (IBV) from infected to non-infected 2 week old commercial broiler chickens, a consumer meat type bird. After the 14 day study only 4% of the birds treated with QR448(a) contracted IBV from previously infected birds versus 22% of birds that contracted IBV from previously infected birds and were not treated with QR448(a). This data shows that treating these birds with QR448(a) produced a statistically significant 5.5 fold decrease in the transmission of IBV compared to birds that were not treated with the QR448(a) compound.

Veterinary poultry products industry experts and those familiar with prevention and control of IBV recognize that abating transmission is perhaps one of the most important ways to economically prevent, control and manage potential losses due to IBV outbreaks.

The Company recently announced positive results of a study to determine the duration of anti-viral effect of QR448(a) against IBV in commercial broiler chickens, which indicated that 1 day old commercial broilers, when treated with QR448(a) were protected 50-100% of the time from the clinical pathogenic effects of IBV for up to 4 days compared to 0-20% of the time in un-treated birds.

The Company plans to continue to build on these recent positive res
