Abortions in Peste Des Petits Ruminants (PPR) infected flocks in Yola North of Adamawa and Askira Uba areas of Borno States, Nigeria.

Peste des petits ruminants (PPR) is a highly contagious viral disease of sheep and goats with as high as 90% morbidity and 80% mortality rates. Although, its substantial economic consequences are reported in goats worldwide, there are currently little information regarding abortion cases in PPR endemic areas in Nigeria. This study investigated occurrences of abortion among PPR infected goats in Yola North and Askira Uba local government areas of Adamawa and Borno States respectively. The study involved analysis of clinical case records of two thousand Sahel goats (n = 2000) procured as part of a livestock restocking program by a government agency. The goats were purchased from local markets and held in quarantine for 2 weeks during which PPR infection was monitored. In the study, a fast spreading infection characterized by severe dehydration, respiratory difficulty, pyrexia, depression, anorexia, nasal and ocular discharges and death of many infected goats informed a suspicion of PPR infection. The number of abortions, mortality and age of the animals were recorded during the investigation. Data were organized in a 2×2 contingency table and analyzed using Chi-square. The overall mortality in both populations was 42% and the occurrence of abortion was 1% and 3% in Yola North and Askira Uba holding sites respectively. The proportion of abortions did not differ significantly (p > 0.05) between both populations but there was a positive association indicated as r = 0.4264 and 0.4638 between the occurrence of abortion and mortality in Yola North and Askira Uba holding sites respectively. In addition, the severity in clinical manifestation of the disease appeared higher in younger goats (< 1 years) than the adult ones. These findings suggest that PPR infection could be associated with abortions in goat flocks found in these PPR endemic areas. [ABSTRACT FROM AUTHOR]
