In a clinical setting (study outline) young chicks were infected with M. gallisepticum and medicated in the drinking water afterwards with Baytril® 10% oral solution or with a reference compound.

The efficacy of the therapeutic medication was assessed according to different criteria, i.e. the airsacculitis lesion score, the cultural reisolation of M. gallisepticum and the serum agglutinin production. It was shown that the Baytril® therapy conferred good efficacy to respiratory disease caused by M. gallisepticum in poultry.
