This study was conducted between April 2000 and March 2001, in 12-month period. During the study, local slaughterhouses were visited periodically for 1 year to examine the internal organs (livers, lungs, spleens and hearts) for the presence of cysts and total 1355 cattle, 218 sheep and 104 goats were examined for the cystic echinococcosis (CE). It was found that 13.5% of cattle, 26.6% of sheep and 22.1% of goats were infected with this disease. While cysts in cattle (P < 0.001) and goats (P > 0.05) were found mostly in lungs (88.5 and 82.6%, respectively), but they were mostly found in livers (P > 0.05) in sheep. In addition to this, three spleens and one heart in cattle were infected with CE. In this study, the prevalence of CE and the number of cysts in ruminants were found different when the cattle, sheep and goats examined were stratified based on age. The prevalence and the number of cysts increased with age approaching an asymptotic prevalence of one in the oldest animals (P < 0.05). The number of cysts in cattle, sheep and goats were increasing at a rate of 0.31, 0.63 and 0.42/year, respectively. The economic decrease in the value of the carcasses because of the discarded liver and lung as a result of CE was estimated as 1.1% (7.5 US dollars per cattle) for cattle, 4.37% (3.2 US dollars per sheep) for sheep and 4.26% (2.9 US dollars per goat) for goats. The minimum total loss for all infected animals was determined to be 583 US dollars in infected animals, based on the market prices in the year 2002.
本研究于2000年4月至2001年3月期间进行，为期12个月。在研究过程中，对当地屠宰场进行了为期1年的定期走访，检查1355头牛、218只绵羊和104只山羊的肝脏、肺、脾脏和心脏等内脏器官是否存在囊肿，以检测囊型包虫病（CE）。结果发现，13.5%的牛、26.6%的绵羊和22.1%的山羊感染了这种疾病。牛（P < 0.001）和山羊（P > 0.05）的囊肿大多出现在肺部（分别为88.5%和82.6%），而绵羊的囊肿大多出现在肝脏（P > 0.05）。此外，有三头牛的脾脏和一头牛的心脏感染了囊型包虫病。在本研究中，根据年龄对所检查的牛、绵羊和山羊进行分层时，发现反刍动物中囊型包虫病的患病率和囊肿数量有所不同。患病率和囊肿数量随年龄增长而增加，在最年长的动物中接近渐近患病率1（P < 0.05）。牛、绵羊和山羊的囊肿数量分别以每年0.31、0.63和0.42的速度增加。由于囊型包虫病导致肝脏和肺被丢弃，估计牛的胴体价值经济损失为1.1%（每头牛7.5美元），绵羊为4.37%（每只绵羊3.2美元），山羊为4.26%（每只山羊2.9美元）。根据2002年的市场价格，所有感染动物的最低总损失确定为583美元。
