Morphology of Paragonimus westermani

In this article we will discuss about the morphology of lung fluke (Paragonimus Westermani). Adult lung fluke is thick, fleshy, oval in shape, reddish brown in colour, about 8-12 mm long and 4-6 mm in diameter. General plan organisation is more or less the same as that of Fasciola. Its anterior end is slightly broader than the posterior end [The morphology of the eggs of Paragonimus westermani (Trematoda)] The entire shape, surface structure and the details in operculum of the eggs of Paragonimus westermani imported to Czechoslovakia by one Korean and three Vietnamese were examined by light and scanning electron microscopy with emphasis on differential diagnostics (a) The Adults of paragonimus westermani live in the bronchi, lungs and occasionally in the liver, spleen and other organs of man, dog, cat, tiger, wolf, beaver, mongoose and pig. (b) The Eggs are present in sputum and more rarely in feces In particular, evidence based on morphology of adult worms is lacking. Metacercariae of the genus Paragonimus, recovered from crabs in two regions of northeastern India, were raised to adulthood in laboratory rats.

  1. Morphological features of Paragonimus adult worms and metacercariae. (a) Representative morphology of metacercariae. (A) P. heterotremus. (B) P. bangkokensis. (C) P. westermani. (D) P. skrjabini
  2. The best-known human pathogen is Paragonimus westermani, widely distributed in eastern and southern Asia, but others occur in Asia (P. skrjabini and P. heterotremus), Africa (P. africanus and P. uterobilateralis) and in the Americas (P. kellicotti and P. mexicanus) . Eight species of Paragonimus have been named from the Americas
  3. The cercariae invade the second intermediate host, a crustacean such as a crab or crayfish, where they encyst and become metacercariae. This is the infective stage for the mammalian host. Human infection with P. westermani occurs by eating inadequately cooked or pickled crab or crayfish that harbor metacercariae of the parasite
  4. Morphology. Living adult worms are pinkish-brown in color and bean-shaped (7 to 15 mm in length, 3 to 8 mm in width, and 3 to 5 mm in thickness). It contains characteristic ovary in the middle part of the worm. The golden brown colored large immature eggs are approximately 45-60 x 80-100 µm

Paragonimus westermani is the major species of lung fluke that infects humans, causing paragonimiasis. The species sometimes is called the Japanese lung fluke or oriental lung fluke . Human infections are most common in eastern Asia and in South America Paragonimiasis is caused by lung flukes of the genus Paragonimus. P. westermani is the most common species of the more than 10 that can infect humans. The disease is prevalent in Asia, Africa, and Central and South America. Humans acquire infection by eating raw or undercooked freshwater crabs or crayfish containing metacercaria Human infection with P. westermani occurs by eating inadequately cooked or pickled crab or crayfish that harbor metacercariae of the parasite Key words: Paragonimus westermani, morphological and molecular variation, new locality, new crab intermediate hosts. INTRODUCTION Among over 50 nominal species in the genus Paragonimus, Paragonimus westermani is the best-known because of its pathogenicity to humans and its wide distribution in Asia (Blair et al. 1999)

The Philippine P. westermani differs from Japanese P. westermani not only in its morphology but also biological and immunological characteristics: therefore, we designate the new name, Paragonimus.

Komiya & Ito have studied the redia and cercaria of Paragonimus westermanii. Observations were made on living material and on material fixed in hot 10% formalin. They found that the arrangement of the excretory system in the rediae was not constant but that the flame cell formula was normally 2[(1+1+1+1) + (1+1+1+1)] = 16. The cercaria is described in more detail, particularly the arrangement.. Among Paragonimus species, Paragonimus westermani followed by P. skrjabini complex are the major pathogens for human paragonimosis in Asia. In addition, P. heterotremus is an important pathogen in southern China and the Indochina Peninsula and is the only proven species to cause human paragonimosis in Vietnam. Morphological and molecular. Evidence for the presence of lung flukes of the Paragonimus westermani in India remains scant. In particular, evidence based on morphology of adult worms is lacking. Metacercariae of the genus Paragonimus, recovered from crabs in two regions of northeastern India, were raised to adulthood in laboratory rats Paragonimus westermani eggs range from 80-120 µm long by 45-70 µm wide. They are yellow-brown, ovoid or elongate, with a thick shell, and often asymmetrical with one end slightly flattened. At the large end, the operculum is clearly visible. The opposite (abopercular) end is thickened. The eggs are unembryonated when passed in sputum or feces

The first case of Paragonimus infection in man, contracted in Szechuan, was reported by CHUNG et al. in 1955 (Zhong Yixue Z., 1955, v. 11, 1117).

  1. Max Braun in 1899 first defined the genus Paragonimus, which initially only included the species P. westermani. In Vietnam, since paragonimiasis was first reported there in 1906, it was presumed for 89 years that only one species of Paragonimus lung fluke, P. westermani, caused paragonmiasis in humans
  2. Paragonimus westermani is one of the most medically important lung flukes and is widely distributed in Asia. It exhibits considerable variation in morphological, genetic and biological features. In central provinces of Vietnam, a high prevalence of metacercariae of this species has been reported from the crab intermediate host, Vietopotamon aluoiense. In this study, we detected P. westermani.
  3. Paragonimiasis is a zoonotic disease caused by lung flukes of the genus Paragonimus. Humans usually become infected by eating freshwater crabs or crayfish containing encysted metacercariae of these worms. However, an alternative route of infection exists: ingestion of raw meat from a mammalian paratenic host

In creating the taxonomy of Paragonimus westermani, a morphological approach is almost always taken.However, classification can be pretty tricky business, as the fluke is not only closely related to other Paragonimus spp., but there is also much variation within the P. westermani species itself. Nonetheless, size and shape of the organism are distinctions often made at the. Paragonimus bangkokensis and Paragonimus harinasutai were found one after another in the same crab host, Potamon smithianus, in Thailand in 1967 and 1968.
