ABSTRACT
Ghazy AA, Ghazi YA, Mahmoud KG, Farghaly AA Incidence of Chromosomal aberrations in
buffalo with brucellosis and cattle with tuberculosis, Onl
J Vet Res., 11 (1) : 12-22,
2007. Chromosomal structural
aberrations were found to be more frequent in buffaloes with brucellosis (5.40 ± 0.72) or cattle with tuberculosis (5.55 ± 0.52), than in non-infected controls
(2.20 ± 0.45) and (3.11 ± 0.60), respectively. Results
suggest that Brucella infected buffaloes could be screened with rose bengal and
immune-chromatographic test and confirmed by specific complement fixation
tests. Moreover, single cervical tuberculin test together with caudal-fold test
confirmed by bacteriological culture of milk could be helpful as diagnostic
tools for bovine tuberculosis in dairy cattle. Structural chromosomal
aberrations in the form of fragments, gaps, breaks and deletions were significantly
increased in buffaloes with brucellosis and dairy cattle with bovine
tuberculosis. Thus, chromosomal abnormalities may be implicated in the
pathogenesis of brucellosis and bovine tuberculosis. Genetic counseling and
consideration of disease diagnosis should be an integral part of planning of
control strategies.
