Caseous Lymphadenitis (CLA) is a contagious chronic disease of
small ruminants caused by a gram-positive aerobic facultative micro
organism. In this study, a cross sectional study was carried out to
estimate CLA prevalence among sheep population in Qualin district.
Out of 315 examined sheep, 10% were showed the clinical signs of
CLA. Serologically, 144 sheep were examined by ELISA which
resulted in a true seroprevalence of 61% (95% CI: 53-69%).
evaluation of application of Betadine on wounds and using of
shearing machine as control measures for CLA in sheep flocks
resulted in the decrease the prevalence of CLA from 9.3% to 2.6 % in
an infected flock. In conclusion, CLA is a endemic disease in the
study area at high levels of prevalence and official control measures
has to be undertaken to minimize its huge economic losses.
