AN OUTBREAK OF CASEOUS LYMPHADENITIS OF GOATS ON AN LIBC FARM, DANGORA - NIGERIA

Abstract

Clinical outbreaks of caseous lymphadenitis (CLA) of goats during July, 1990 and June, 1991 in Livestock Investigation and Breeding Centre (LIBC) Dangora, Kano State - Nigeria is reported. The out-break was found to be (26%) in the 100 goats examined. Clinical findings observed were palpable abscesses which occured in the prescapular, prefemoral and submaxillary lyruphuodes. Similar abscesses were also submaxillary lymphnodes. Similar abscesses were also found on the face and udder. The most frequently affected sites were prescapular lymplinodes with (42.28%) followed by submaxillary lymphinodes with (17.86%). Of the 26 goats affected, (61.54%) were males while (38.46%) were females. Coryncbacterium pseudotuberculosis was consistently isolated from seven specimens out of of the eight samples tested bacteriologically. One specimen, was negative to isolate as the animal was treated for other disease before sampling. It is suggested that caseous ymphadenitis is an important disease of goats in Nigeria and comprehensive studies on the Pathogenesis, epidemiology and the economics of the disease in Nigeria should be pursued.
