Abstract
The point prevalence rate of antibodies to peste des petits ruminants (PPR) in 8 local
government areas of Adamawa State was determined by competitive Enzyme linked
immunosorbent assay. A total of 280 goat sera were sampled, out of which 176 (62.9%)
tested positive to PPR antibodies. The antibodies to PPR were detected in all the local
government areas of the State with Mubi having the highest prevalence rate of 76.0% and
Jada had the least of 55.3%. There was no significant difference between the various local
government areas (P > 0.05),The prevalence rate for males (53.6%) was significantly
different from that of the females (69.0%). The age-specific rate for 0-6 months age group
was 43.4%, for the 7-12 months, 54.2% and those greater than 12 months was 87.6%.
There was a significant difference in age specific rate (P < 0.05). Males that aged 0-6
months had an age specific prevalence rate of 45.2%, whereas females of the same age had
40.0%. Males aged between 7-12 months had 44.7%, whereas females of the same category
had 62.0%. Males above 12 months had an age specific prevalence rate of 77.4%, similarly
females of the same age had 93.2%. There was a statistical significant difference in the age
- sex specific rates. Red Sokoto goats had a breed specific rates of 52.6% and Sahelian had
52.3%. Even though there was no statistically significant difference between these breeds,
there was a difference in breed specific rate between the pure breeds and their crosses;
mixed breeds had a breed specific rate of 87.6%.
The prevalence rate of antigens to PPR in 9 reported outbreaks in the state was also
determined using immunocapture enzyme linked immunosorbent (I (-F.LISA). Seventy
five out of the 109 samples tested (68.8%) were positive to PPR antigens. About 82.7% (62
out of 75) of the "suspects" tested positive and 38.2% (13 out of the 34) of the apparently healthy incontact goats tested positive. There was significant difference in the percentage
positive tested from suspects and normals.(X2= 5.64, (p < 0.05). The sex-specific rate for
males was 75.9% and females 61.8%. The age group 0-6 months had the highest agespeeifie
rate of 89.5% tested positive; 7-12 months had 61.7% and those greater than one
year had 50.0%. There was a statistically significant difference in age-specific rates of
detection rate of antigens of PPR. Breed specific rates to PPR antigens in the reported
outbreaks indicated that red sokoto had 82.4% and sahelian breeds had 82.9%, whereas
their mixed breeds had the least breed specific rate 45.0%. There was a statistically
significant difference between the pure and cross breds (P < 0.05). There were four
reported outbreaks in the rainy season and 5 in the dry season. More death occurred in
the dry season (52.8%), than in the rainy season (47.2%). There was a statistical significant
difference in mortalities between the two seasons.
The overall finding in this study indicated the presence of the disease (PPR) in Adamawa
State with the conclusion that PPR may be a major cause of mortality limiting goats
production.
