Abstract
A cross-sectional study was conducted in and around Debrebrihan , North Shewa zone of Amhara
region to determine the Seroprevalence of brucellosis in ruminants and human in and
around Debrebrihan from November 2013 to May 2014. A total of 384 ruminants (cattle, sheep
and goats) and 134 human patients were randomly selected samples serologically tested for
brucella antibodies. In addition, questionnaire survey involving 150 community members carried
out to assess their perception about the disease. The overall seropositivity in ruminants in the
study area was found to be 2.3% (95% CI: 0.01-0.04) by RBPT and 0% by CFT. The overall
brucella seropositivity in a human was found to be 13.4 %( 95% CI: 0.08-0.19) by RBPT and
CFT. There were statistically significant difference in the prevalence of human brucellosis
between different occupations (χ2 = 10.26, P = 0.006), raw milk consumption (χ2 = 4.56, P = 0
.033) and contact with placenta (χ2 = 72.08, P = 0.000) identified as risk factors of brucella
infection. The multivariable logistic regression analysis showed that being a farmer had 4.7 times
the odds of being brucella reactors compared with those patients having other occupations and
having raw milk consumption habit had 7.05 times the odds of being brucella reactors compared
with those patients not having raw milk consumption. However, there was no statistically
significant difference between male and female(x2 =0.51, p=0.48), age groups (χ2 = 1.34, P =
0.51), education levels (χ2 = 5.28, P = 0.153) and raw meat consumption (χ2 = 3.55, P = 0.060) in
the prevalence of human brucellosis. This finding revealed that there was no ruminant and human
brucellosis in Debrebrihan. However, there was high prevalence of human brucellosis in other
districts of north shewa zone around Debrebrihan. Hence, the study suggests that the need for
implementing control measures and raising public awareness for prevention of brucellosis in the
area of high prevalence of human brucellosis.
