The collection of lymphatic fluid from the bovine udder and its use for the detection of Mycobacterium avium subsp, paratuberculosis in the cow.

The article explains the role of lymphatic fluid in screening Mycobacterium avium subspecies paratumberculosis (MAP) in cattle. The study was performed on 58 cows, where lymph fluid was extracted from their udders to identify traces of MAP through nested polymerase chain reaction.
