Abstract
Aim: To determine the
Brucella antibodies in one-humped camel (Camelus dromedarius)
herds in Yobe State, North-eastern Nigeria.
Materials and Methods: Blood samples were aseptically
collected from four hundred (400) camels comprising 168 males and
232 females from the five agricultural zones of Yobe State. The
sera obtained from the blood samples were screened by C-ELISA. In
addition, a structured questionnaire was administered to the
herdsmen to obtained information on pastoralist personal data such
as age, educational background, family size, and type of labour
employed. Other information includes herd size, herd medical
history, and patronage of veterinary services.
Results: 66 (16.5%) of the 400 screened camels were found
seropositive for Brucella. This was comprised of 26 (6.5%) male
and 40 (10.0%) female camels. Out of the 66 seropositive camels,
2(0.5%) and 64 (16.0%) were young and adult camels, respectively.
Geidam agricultural zone of the state had the highest specific
sero-prevalence of 24 (6.0%), followed by Gashua 19 (4.75%), Nguru
11 (2.75%), Potiskum 8 (2.0%), and Damaturu 4 (1.0%). There was a
significant statistical association between the age of camel and
serological reaction to C-ELISA (P>0.05), with the adult camels
more significantly associated with Brucella infection OR = 7.881
(1.880 – 33.039; P>0.05) than the young camels. There was no
significant statistical association (P>0.05) between sexes of
camels and positive serological reaction to C-ELISA. Low level of
education, low patronage of veterinary services, and lack of
vaccination against brucellosis were observed among the herdsmen.
Conclusion: A high seroprevalence of brucellosis among the
camels of all the agricultural zones of the state indicates that
the disease is endemic and camel is one of the animals that
perpetuate and sustain the disease.
Keywords: antibody, brucellosis, camel, C-ELISA, odds
