The sensitivity of the Baermann method for the diagnosis of primary Dictyocaulus viviparus infections in calves.
Data from calves infected experimentally with 20 larvae of Dictyocaulus viviparus demonstrate that the Baermann method, using 30 g of faeces per calf is extremely sensitive for diagnosis of patent infections in young cattle. Between 5 and 7 weeks after primary infection it is sensitive enough to diagnose the presence of one patent female worm.
