In spite of the devastating effect of tuberculosis in man arid animals, studies regarding bovine tuberculosis
have not been done. in the Sulaimani districts so far, the aim of the present study was to investigate for the
first time, the prevaience of tuberculosis in cattle in the Sulairnani districts" The study was carried out among
five groups of bovine (the pregnant cattle at last two months of gestation, recentiy parturient cattle (two
months after parflrition), under six rnonths age calves, caives of six months to two years old heif'ers and cattle
above h+,o ],ears old (but not belonging to the first and second groups), from June to December 2000.
The stud.v includes the field observation, using the single intradermal comparative tuberculin test
(SIDT) u'hich involved (4012) cattle from differont Sulaimani dishiets (Sulaimani center, Haiabja, Penjrven,
Rania, Chamchamal, Darbandikhan). The field observation has shown Zlt (5.1%) positive reactors to (SIDT).
The results have revealed highest positive rate in Halabja district, where the rate was (9%) and lowest rate in
Darbandikhan. where the rate was (1.5%), while different prevalence were detected (3.59L, 4%, 53% and 6%)
in Chamchamal. Penjwen, Sulaimani center and Rania respectively. The prevalence rate was also high (6.1%)
in a group of cattle that rvere classified at a stage of two months after delivery (two months from parturition)
and no incidence was detected in a group of calves under six months of age.
Out of 207 SIDT positive reactor catile, (117) sputum samples were examined by direct smear with Zihle -
Neelsen stain, positive result lvas 37 (31.7%) only The samples were also cultured on Modified Lowenstein-
Jensen media, which showed 45 (38.5%) positive growth. This study included also the abattoir observation,
by routine meat inspection of 7375 carcasses that have been slaughtered in Sulaimani abattoir, the result
revealed 65 {A.9%) positive carcasses that showed typicai lesions of tuberculosis. The samples from the
lesions were submitted to the microbiological and histopathological examinations that confirrned the
preliminary diagnosis. The photos are also sl.iown.
