AB  - Among the 10 native cats of Iran, the Felis chaus is considered as one of the 
      largely unknown species. Despite the reports on jungle cats in southeast Iran, 
      there is no comprehensive information about their parasitic diseases. Scanning 
      electron microscope (SEM) provides a valuable tool for the study of these 
      organisms. In October 2022, a 15-year-old male jungle cat (F. chaus) was examined 
      for gastrointestinal parasites using SEM which revealed exact parasite structures 
      such as the mouth, shape of the lips, teeth and their position, papillae, 
      excretory pore, and amphids. SEM of the Taenia taeniaeformis found in the F. 
      chaus intestinal epithelium revealed that this tapeworm consisted of four unarmed 
      suckers and a large armed rostellum. The rostellum was observed bearing double 
      rings of alternating and circular hook arrangements. There were 21 large hooks in 
      the anterior ring and 21 slightly smaller hooks in the posterior one. This study 
      is the first report of Joyeuxiella echinorhyncoides from a jungle cat (F. chaus) 
      in southeastern Iran. The rostellum was cylindrical and armed with thorn shape 
      hooks that covered the whole rostellum with similar density. It was armed with 
      20-30 long hooks arranged in 16 rows. Four big suckers were visible at the base 
      of the rostellum, two on each side. The suckers were round, and unlike the 
      rostellum, these structures were unarmed. The results of the present study 
      observed under SEM, indicated that organs such as sucker and rostellum in 
      cestodes and mouth and the shape of lips and teeth in nematodes played a 
      significant role in the biology of these helminths. The SEM reveals the surface 
      structures and their relationships which results in better distinguishing the 
      species and showing their detailed differences. More SEM studies need to be 
      conducted on other species of cestodes and nematodes, along with pathological 
      tests, to obtain more comprehensive and precise information about how these 
      parasites harm this jungle cat host. The results of present study indicate that 
      morphological details are important which should be considered in the 
      classification. Meanwhile, external structures described herein using SEM, 
      further investigation using transmission electron microscope provide more data on 
      the biology of the parasites. RESEARCH HIGHLIGHTS: Light microscopy is the first 
      step to identify the parasites. High magnification 3D images of the SEM reveal 
      the surface structures of parasites and their relationships precisely. SEM study 
      of the parasites results in distinguishing the species and showing their detailed 
      differences.
