Broiler chicken’s production considered a very important sector of Egyptian poultry production. Diarrhea is a common problem that Threaten poultry production. There are many causes of broiler chicken’s diarrhea as; nutritional causes, infectious causes (viral, bacterial and parasitic). Larvae rarely infest and cause diarrhea in chickens but if present they irritate intestinal mucosa which causes a secondary bacterial diarrhea. In our investigation, intestinal myiasis was reported as uncommon cause of broiler chicken diarrhea in Egypt. The collected larvae were identified using scanning electron microscope study which revealed that; it is 3rd larval stage of M. domestica; creamy white in color; the length of the larvae ranged from 10-12 mm (10.5 ± 0.3); the anterior end contain the black colored cephalopharyngeal skeleton; the anterior spiracles present in the 2nd segment and had a number ranged from 6 to 8 rounded spiracular openings. The spines present in the group resembles the combs which present in the spinose area. The spinose comb contains from 5 to 9 spines which is small and triangular with slightly tapering ends. The posterior peritremes contain three snake or S- shaped or even tortoise openings; with central button; the peritreme was complete; the distance between the two peritreme ranged from 70- 100 μm in length.

家蝇Musca domestica L.(Diptera:Muscidae)幼虫在肉鸡中引起的意外肠肌病:一项现场研究

肉鸡的生产被认为是埃及家禽生产的一个非常重要的部门。腹泻是威胁家禽生产的普遍问题。肉鸡腹泻的原因有很多;营养原因,传染原因(病毒,细菌和寄生虫)。幼虫很少侵染并引起鸡的腹泻,但是如果存在,它们会刺激肠粘膜,从而引起继发性细菌性腹泻。在我们的调查中,据报道,肠道肌病是埃及肉鸡腹泻的罕见原因。收集的幼虫通过扫描电子显微镜研究鉴定,结果表明:它是3的幼虫阶段家蝇; 乳白色 幼虫的长度在10-12毫米(10.5±0.3)之间; 前端含有黑色的头咽骨架。前气孔存在于2段,其数为6〜8的圆形开口spiracular不等。该组中的棘类似于存在于棘区域中的梳子。刺状梳包含5到9个刺,这些刺很小且为三角形,末端稍有锥度。后腹膜包含三个蛇形或S形或什至是龟形的开口。带中央按钮;证明是完整的;两种peritreme之间的距离范围为70-100μm。
