Iowa State University researchers have discovered a potential reason for the presence of avian influenza in U.S. dairy herds, linking the virus to raw milk. Their study revealed that bovine mammary gland tissue contains receptors for the avian influenza virus, suggesting a pathway for infection. The idea emerged after the virus was detected in raw milk. The research team, led by Professor Todd Bell, focused on understanding why this infection occurs, finding that the mammary gland receptor allows the virus to enter and reproduce.
The team also identified a receptor associated with human influenza, raising concerns about potential cross-infection and the creation of new viruses. However, they found little evidence of bird flu in cattle respiratory systems. As of July 12, avian influenza has been detected in dairy herds in 12 states, including Iowa. The research aims to inform regulatory decisions on testing and biosecurity to prevent virus spread. Future studies will investigate other domestic animals and potential infection points.
