Out of 58 live tilapia fish, five Oreochromis niloticus were found to be naturally infected with Henneguya suprabranchiae (8.62%). Such infection was recorded only during winter season from Bahr Shebin, a tributary of the River Nile at Menoufia Governorate, Nile Delta, Egypt. Based on the structure and measurements of fresh spores, this parasite was identified as H. suprabranchiae. Spores are oval in shape and they measure 15 (13-16) x 5 (4-6) microm length by width. It has two polar capsules inside and they measure 4 (5-7) x 1 (2-3) microm length by width. Each polar capsule has spirally coiled (7-9 turns) polar filament. The plasmodia as well as all other parasitic stages were described using light and transmission electron microscopy and discussed regarding to those of other fish hosts especially those of Africa.
在58条活罗非鱼中，发现5条尼罗罗非鱼自然感染了鳃内亨内吉亚虫（感染率为8.62%）。这种感染仅在冬季于埃及尼罗河三角洲米努夫省尼罗河支流巴赫尔·谢宾被记录到。根据新鲜孢子的结构和测量结果，该寄生虫被鉴定为鳃内亨内吉亚虫。孢子呈椭圆形，长15（13 - 16）微米，宽5（4 - 6）微米。其内部有两个极囊，长4（5 - 7）微米，宽1（2 - 3）微米。每个极囊有螺旋状盘绕（7 - 9圈）的极丝。使用光学显微镜和透射电子显微镜对孢原质以及所有其他寄生阶段进行了描述，并与其他鱼类宿主尤其是非洲鱼类宿主的相关阶段进行了讨论。
