Abstract:
Across- sectional study was carried from April 2015 to October 2015 to
determine the prevalence of, and to identify Risk factor for Brucellosis
infection in camels (Camelus dromedarius) in Gadarrif State, Sudan.
A total of 252 camels from 60 camel herds were included in this study, The
Study was conducted in four selected locality in Gadarrif State. From
Algadarrif (109), Butana (93), Wast Algadrrif (15), and Alshwak (35)
Localities. Of these,
8.4 % (215 out of 252), and 13.5% (37 out of 252) were female and male
camels respectively.
Atotal of 252 samples were collected and screened by and Rose Bengal Plate
Test (RBPT). Among these, 23 were positive giving an individual prevalence
rat of (9.2). This Study show that the occurrence of the disease was slightly
higher in Algadarrif (89.o %), Butana (89.2%), and Alshwak (92.1%)
(P<.25). Seroprevalence of Brucella in male 13.6% relatively higher than that
of female camels which was 8.4%. also the disease was slightly higher in
Arabi(11.1%) ,Anafi (9.7%) , and Bushari (2.9%) (OR=.270; 95% CI: .034 to
2.160, P=.143) . Immature camels had asignificant higher than adult
, this Study the Seroprevalence of Brucella was higher in Age (1-5 years)
28.0%, (>11 years) 9.1%, and in (6-10 years) 6.2%. there was also significant
increasing Seropositivity with respect to increasing herd size ( P>0.25)
Seropositivity was large herds (>70 ) 10.6% , in moderate herds(<50 ) 4.8%
,and small herds ( <20 ) 3.1% .
Mixed camels with other ruminants showed significant of camels Brucellosis
(P> o.25). Camels reared with other ruminants showed Seroprevalence of
14.3% which was higher than that in camels kept alone 7.9%. (OR=8.693;
95% CI: .656 to 11.258, P=.162)
vii
Also Study showed Seropositivity of aborted camels were 81.8% which was
highest than other one was not aborted camels 2.2% (OR= .002; 95% CI: .000
to.017, P=.000) . and Seropositivity Inbreeding camels 11.2% Compared
with the marketing camels 4.9% locality, Body condition were not found
significantly associated with brucellosis (P>0.25) in the Univariate analysis.
Multivariate analysis showed that abortion higher significantly (Exp .000 -
.017, P-value .000).
The results of the present study provide the status of Seropositivity to Brucella
in camels in Algadarrif and the risk factors that contribute to Seropositivity in
dromedaries and showed that brucellosis is widely distributed disease among
camel herds in Algadarrif State.
