Abstract

Objective: To reobserve and research the specimen of Paragonimus worm found in the left lung of a New Guinea native in 1926, which was previously identified as Paragonimus westermani Kerbert or Paragonimus ringeri Cobbold.

Methods: Using reconstructive software and microscopy to observe some organs of the worm, and compared with other species of paragonimus.

Results: The three dimensional (3D) views of ovary and two testes of New Guinea specimen showed that the ovary was clearly divided into six lobes. These two testes were situated oppositely in the body. One teste was divided into four branches, while another was divided into five. The cuticular spines were arranged in groups over the entire skin covered in a slide, each group was consisted of two to four single spine.

Conclusions: Based on 3D views and measurements, we reclassified it as Paragonimus siamensis. This was also the first report of human case infected by Paragonimus siamensis.
