A new myxosporean parasite, Myxobolus lubati n. sp., was described from the wall of the intestine of haffara seabream Rhabdosargus haffara (Forsskal 1775), Red Sea, Egypt. Macroscopic plasmodia of about 300 mum diameter were located in the circular muscle layer of the intestine. The spores were ovoid and sometimes ellipsoid and measured 9.8 x 7.2 mum. The shell wall of the spore was thickened at the posterior end and marked with 5-7 sutural markings. Polar capsules were equal and pyriform with three polar filament turns situated in the posterior half of the polar capsule. Polar capsules measured 4.2 x 1.6 mum. Histological evaluation of the infection revealed a slight distention of the intestinal layer of muscularis. Ultrastructure of the plasmodial wall and sporogenesis of the present species followed the usual pattern valid for most studied myxosporean species.
一种新的粘孢子虫寄生虫，鲁氏粘体虫（Myxobolus lubati n. sp.），是从埃及红海的哈法拉鲷（Rhabdosargus haffara，福斯卡尔，1775年）肠道壁中描述的。直径约300微米的宏观孢子体位于肠道的环形肌层。孢子呈卵形，有时为椭圆形，大小为9.8×7.2微米。孢子的壳壁在后端增厚，有5 - 7条缝线标记。极囊相等，呈梨形，有三个极丝圈位于极囊后半部。极囊大小为4.2×1.6微米。感染的组织学评估显示肌层肠层有轻微扩张。本物种的孢子体壁超微结构和孢子发生遵循了大多数已研究的粘孢子虫物种通常的模式。
