本文旨在识别2019年在朱拜勒市中央鱼市商店定期例行检查鱼类卫生状况和健康状况时收集的寄生虫,沙特阿拉伯。来自橙色斑点石斑鱼(Epinepheluscoioides)鱼的样品在肌肉纤维之间显示出浓重的黑色条纹,这些条纹被认为无法销售,并在被切割并准备密封后被消费者拒绝。黑色变色是以重扩散的焦点黑点或形成嵌入鱼整个全身肌肉组织中的可变大小的线的形式。对这些样品进行寄生虫学和病理学评价。对受影响的肌肉组织进行的寄生虫学检查显示,霍夫马内拉属感染。鸡蛋。根据卵的形态和超微结构特征鉴定了寄生虫感染。对受影响的鱼的检查显示,肌纤维之间存在多灶性黑色寄生残留物。寄生碎片分布在整个鱼肉上,无论是皮下区域的表面还是肌肉组织的深处,它们都集中在脊柱周围的肉中。总而言之;该病例报告证实了Huffmanelaspp的发生。通过使用光学和扫描电子显微镜对斜纹石斑鱼肌肉的感染。建议进一步的分子评估。
This paper is conducted for identifying the parasite which collected during regular routine inspection for the hygienic condition and health status of fish in 2019 at the central fish market shops at Jubail city, Saudi Arabia. Samples from an orange spotted grouper (Epinephelus coioides) fish showed heavy black streaks between the muscle fibers that was considered unmarketable and rejected by the consumer after had been cut and prepared for sealing. The black discolorations were in the form of heavy diffused focal black spots or forming threads of variable sizes embedded in the entire whole-body musculature of the fish. These samples were subjected to parasitological and pathological evaluation. The parasitological examination of the affected muscular tissues revealed infection by Huffmanela spp. eggs. The parasitic infection was identified on the bases of the morphological and ultra-structural characters of the eggs. The examination of the affected fish showed multifocal black parasitic remnants between the muscle fibers. The parasitic fragments were distributed all over the fish flesh either superficially in subcutaneous area or deep inside the muscular tissue and they have been concentrated in the flesh around the vertebral column. In conclusion; this
case report confirmed the occurrence of Huffmanela spp. infection in the muscles of Epinephelus coioides by using light and scanning electron microscopy. Further molecular assessment is recommended.
