对2005年至2007年在坦桑尼亚阿鲁沙市屠宰的临床健康的115，186头牛，61，551只绵羊和37，850只山羊进行了屠宰场调查。目的是确定影响肺部的疾病的患病率。常规肉类检查程序用于检测病理病变的存在。分别有15，245（13.2%）、4，668（7.8%）和3，192（8.4%）只牛、绵羊和山羊的肺因9种疾病/病症（即肺炎、包虫病、肺气肿、脓肿、炭疽病、胸膜炎、钙化囊肿、黑变病和牛肺结核）而报废。肺炎是导致死亡的主要原因，分别占牛、绵羊和山羊死亡肺的4594（30.1%）、1495（31.4%）和1072（33.6%）例。炭疽病、胸膜炎、黑变病和肺结核仅在牛中记录，分别占肺病变的7.3%、6.4%、2.9%和0.7%。2005年、2006年和2007年记录的肺部疾病百分比在牛、绵羊和山羊之间没有统计学差异（P > 0.05）。牛的不同肺病变率显著高于绵羊和山羊（P < 0.05）。雨季和旱季各疾病所致的肺谴责率差异无显著性（P > 0.05）。由于包虫病和结核病具有人畜共患的性质，它们的发生可能对公共卫生构成威胁。研究表明，坦桑尼亚国内反刍动物的不同肺部疾病/病变普遍存在。因此，有必要对影响肺部的疾病采取适当的控制措施，以尽量减少感染率并减少随之而来的经济损失。从这次调查中获得的数据不能完全被认为是准确的，但可以用作更广泛的流行病学调查的基线。(C)2010爱思唯尔有限公司版权所有。
An abattoir survey was conducted on clinically healthy 115,186 cattle, 61,551 sheep and 37,850 goats slaughtered in Arusha municipality, Tanzania, between 2005 and 2007. The objective was to determine the prevalence of disease conditions affecting the lungs. Routine meat inspection procedures were used to detect the presence of the pathological lesions. A total of 15,245 (13.2%), 4668 (7.8%) and 3192 (8.4%) lungs of cattle, sheep and goat, respectively, were condemned due to nine diseases/conditions namely pneumonia, hydatidosis, emphysema, abscesses, anthracosis, pleurisy, calcified cysts, melanosis and bovine pulmonary tuberculosis. Pneumonia was the leading cause of condemnations as it was responsible for 4594 (30.1%), 1495 (31.4%) and 1072 (33.6%) of all the condemned lungs in cattle, sheep and goats, respectively. Anthracosis, pleurisy, melanosis and pulmonary tuberculosis were only recorded in cattle attributing to 7.3%, 6.4%, 2.9%, and 0.7% of lung condemnations, respectively. The percentages of lung conditions recorded in 2005, 2006 and 2007 were not statistically different (P > 0.05) among cattle, sheep and goats. The different lung lesion percentages recorded in cattle were significantly higher (P < 0.05) compared to sheep and goats. There were no significant (P > 0.05) variations between lung condemnation percentages due to various diseases during the rainy and dry seasons. Because of their zoonotic nature, occurrence of hydatidosis and tuberculosis may pose a public health risk. The study showed that different lung diseases/lesions in domestic ruminants are prevalent in Tanzania. Thus, there is a need to introduce appropriate control measures of diseases affecting lungs to minimize the rate of infection and reduce the ensuing economic losses. data obtained from this survey cannot be wholly relied upon as accurate, but it can be used as a baseline for more extensive epidemiological investigations.
