ABSTRACT
<p><b>OBJECTIVE</b>To establish and estimate incidence of contagious bovine pleuropneumonia (CBPP), using abattoir survey as a diagnostic tool in slaughtered cattle in Northern Tanzania.</p><p><b>METHODS</b>A total of 4 460 cattle were slaughtered in five abattoirs in 3 northern zone regions (Arusha, Kilimanjaro and Tanga) during the period of January to May 2004. They were examined ante-mortem for 'pneumonia signs', and 'characteristic contagious bovine pleuropneumonia (CBPP) lung lesions'.</p><p><b>RESULTS</b>Forty-one (0.91%) of the slaughtered cattle, the majority of which were Tanzania short horn zebu, had gross lung lesions suggestive of CBPP. The prevalence of lesions was significantly (P<0.05) higher in Karatu abattoir compared to others. No animal was detected to have lesion in Bomang' ombe abattoir. The most observed pneumonic signs included labored breathing (90%), dry cough (57%) and mucopurulent nasal discharge (47%). The gross characteristic CBPP pathological lesion, frequently encountered was left lung lesion (47%), pinkish lung (71%) and pleural adhesion (98%). Epidemiological reports show that the CBPP reported outbreaks increased from 19 in 2002, 65 in 2003 and 18 in 2004 (January-March). The corresponding number of reported deaths increased from 137 in 2002, 269 in 2003 and 77 in 2004 (January-March).</p><p><b>CONCLUSIONS</b>It's concluded from this study that CBPP is a problem in spite of the extensive awareness and vaccination campaigns. Nevertheless, a continued surveillance programme including routine checks of all cattle carcasses at the abattoir and subsequent epidemiological investigation of suspected cases are recommended.</p>
