Abstract

The oesophagus, diaphragm and heart of 103 camels slaughtered at Al-Ahsa abattoir were investigated for infection with sarcocysts. Sarcocystis cysts were found in 91 camels (88.35%): in the diaphragm of 79.6%, oesophagus of 72.8% and heart of 71.8%. Two morphologically distinct sarcocysts were found. Thin-walled cysts (141-400 x 70.5-188 microns) were in all the three indicator organs while the thick-walled cysts (170-194 x 117.5-188 microns) were only found in the oesophagus. Experimental feeding of four cats and two dogs with sarcocysts-infected meat showed that cats were refractory to the infection while dogs excreted Sarcocystis sp. sporocysts (10.7-14.3 x 8.3-10.7 microns mean, 13.2 +/- 0.32 x 9.4 +/- 0.20 microns) after a prepatent period of 9-10 days. It was concluded that dogs may be the final host of both types of sarcocysts or that one of these cysts develops in dogs while the other one uses other carnivores living in the desert as the final host.

摘要

对在艾哈萨屠宰场宰杀的103头骆驼的食管、膈肌和心脏进行了肉孢子虫感染情况调查。在91头骆驼（88.35%）中发现了肉孢子虫囊肿：在膈肌中发现的占79.6%，在食管中发现的占72.8%，在心脏中发现的占71.8%。发现了两种形态不同的肉孢子虫囊肿。薄壁囊肿（141 - 400×70.5 - 188微米）在所有三个指示器官中均有发现，而厚壁囊肿（170 - 194×117.5 - 188微米）仅在食管中发现。用感染肉孢子虫的肉对4只猫和2只狗进行实验性投喂，结果表明猫对感染具有抗性，而狗在9 - 10天的潜伏期后排出了肉孢子虫属孢子囊（平均大小为10.7 - 14.3×8.3 - 10.7微米，13.2±0.32×9.4±0.20微米）。得出的结论是，狗可能是这两种肉孢子虫的终末宿主，或者其中一种囊肿在狗体内发育，而另一种则以生活在沙漠中的其他食肉动物作为终末宿主。
