Current status of pseudo-tuberculosis,caseous lymphadenitis among sheep and goats in Saudi Arabia
Abstract: The incidence of pseudo-tuberculosis among sheep and goats in the Kingdom increased considerably in the last few years. The main factors contributing to this increase among breeding and slaughter animals were reviewed. They include the importation of large number of affected animals and the use of certain type of barely with sharp awns as animals feedstuff. The latter predispose the infection through abrasions in the mucous membrane of the alimentary tract.
Corynebacterium ovis was isolated from samples collected from affected sheep of 10 flocks located in Riyadh (3), Qassim (2), Medina (10), Taif (3), and Asir (1) regions. Identification of the isolated organisms was based on cultural, microscopically and biochemical parameters. In-vitro, antimicrobial sensitivity tests indicated that the isolated strains were susceptibility to penicillin, erythromycin and kanamycin. However, in-vivo chemotherapeutic trials were not effective.
Recently, a control program was initiated in which the attenuated tubercle bacillus of Calmette and Guerin (BCG) is used as immuno-potentiating agent. Non affected animals in flocks with pseudo-tuberculosis problem are currently selected and inoculated with BCG. The evaluation of the efficacy of this control method is in progress. In addition, the importance of controlling animal importation and selecting good types of barely without harmful awns for use as animal feedstuff were discussed as other means to reduce the incidence of pseudo-tuberculosis in the Kingdom.
