Treatment
Both cattle investigated in June 2008 received previous anthelmintic treatment of the ML group with no apparent response. [flockandherd.net.au]
Epidemiology
Antibody measuring methods have several disadvantages, most notably a lack of sensitivity and specificity, which limits their use in longitudinal epidemiological studies. [typeset.io]

Prevention
In both cases, treatment with macrocyclic lactones (MLs) failed to prevent and/or resolve clinical signs prior to investigation. This raised concerns that resistance in Ostertagia ostertagi to macrocyclic lactones had played a role. [flockandherd.net.au]
