Abstract
The susceptibility of West African Dwarf (WAD) goats to
experimental C1 ruminantium infection was evaluated over a period
of 9 weeks using ten infected and four control animals. All the
10 infected goats reacted following intravenous inoculation of
C. ruminantium infected blood. The incubation period varied from
9-11 days.
Two of the WAD goats infected reacted hyperacutely 12 days postinfection
high temperature (41°C + 0.5) was maintained for 3
days, the animals then collapsed and died in convulsion without
obvious clinical signs.
Three of the 8 infected WAD goats reacted acutely 15 days postinfection,
the temperature remained high for 4-6 days and then
became subnormal before the animals died. Fever, incordination
intermittent convulsion circling and paddling movements where the
main clinical features seen in these acutely affected animals.
Five of the 8 infected WAD goats which reacted acutely recovered
from the infection after maintaining a high temperature (41°C +
0.5) for 8-9 days suggesting the mild form of the disease. No
other clinical signs were observed at 20 days post-infection.
Since some of the clinical signs of the disease manifested by
these infected WAD goats were severe leading to death in 5 of the
10 infected goats, it is hereby concluded that, WAD goats are
susceptible to C.ruminantium infection, and that both mild and
fatal cases of the disease also exist in experimental WAD goats.
