American Association of Swine Veterinarians - Proceedings, 2007, 135-138
Merial Limited recently developed a M. hyopneumoniae bacterin designed to be administered with the transdermal needle-free injection system DERMA-VAC® in order to reduce the potentiation of PRRSV-induced pneumonia by M. hyopneumoniae in co-infected pigs. The effect of vaccination was evaluated using an experimental challenge protocol including 66 pigs distributed as follow:
