A cross-sectional study of brucellosis in small ruminants was carried out from October 2008 to March 2009 in Jijiga District,
Somali Regional State of Ethiopia. Seven hundred thirty sera samples (421 of sheep and 309 of goats) were randomly collected
from purposively selected villages of the study area. Structured questionnaire format was developed, pre-tested and administered
to assess the perception of the community pertaining to brucellosis in sheep and goats. Sera samples were screened by Rose
Bengal Plate Test (RBPT), and all samples tested positive by the RBPT were subjected to Complement Fixation Test (CFT) for
confirmation. Of 12 serum samples that were positive by RBPT, 11 were positive by CFT. Statistically significant differences
were not observed between the species as well as the sex groups (P > 0.05); however, the variation between the age groups was statistically significant (P < 0.05). Analysis of the questionnaire survey suggests that improper handling of aborted materials, consumption of raw milk,
and lack of awareness about the disease, among others, might greatly contribute to further spread of brucellosis in their
livestock and exposes the community to a public health hazard. In general, the sero-prevalence in the study area was not so
high; nevertheless, appropriate brucellosis control and prevention methods should be implemented to circumvent future potential
for economic losses and the public health hazard of the disease. 相似文献

A cross-sectional serological survey was undertaken in selected districts of different agro-ecology of Jimma zone (Dedo, Yebu,
Seka, Serbo, and Jimma town) from November 2009 to February 2010 to determine the seroprevalence of African horse sickness
virus and associated risk factors of the disease. Two hundred seventy-four equids (189 horses, 43 mules, and 47 donkeys) with
a history of non-vaccination for at least 2 years were selected randomly from the above areas. Sera samples were collected
and assayed for the presence of specific antibody against African horse sickness virus using blocking ELISA. An overall seroprevalence
of 89 (32.5%) was found and it was 24 (51.1%) for donkeys, 13 (30.2%) for mules, and 52(28.3%) for horses. Seroprevalence
was significantly (X
2 = 11.05, P < 0.05) different among the different species of equids. Seroprevalence was also significantly (X
2 = 11.43, P < 0.05) different among the different agro-ecological areas being higher in highlands 47 (40.5%) followed by midland 30 (34.5%)
and lowland 12 (16.9%). Age and sex were not significantly (X
2 = 3.15, P > 0.05 and X
2 = 3.38, P > 0.05, respectively) associated with seroprevalence of AHSV. The present study showed that African horse sickness (AHS)
is highly prevalent disease for the horses followed by mules and then donkeys in Jimma zone explained by lower seroconversion
rate. Therefore, control strategy against AHS should target at high risk species of all age and sex in their locality in the
initial stage for better containment of the disease. 相似文献
