Paragonimus westermani: Biochemical and immunological characterizations of paramyosin
Experimental Parasitology, 2007Paramyosin of the helminth parasite is a muscle protein that plays multifunctional roles in host-parasite relationships. In this study, we have cloned a gene encoding Paragonimus westermani paramyosin (PwPmy) and characterized biochemical and immunological properties of the recombinant protein.

Triploidy in Paragonimus westermani
Parasitology Today, 1991The finding of triploid and diploid forms of Paragonimus westermani in Japan has caused tremendous controversy over the identity and speciation of this parasite. Should these two genetically different forms be given different specific names? Hirohiso Hirai and Takeshi Agatsuma have studied the lung flukes by using cytogenetic techniques and zymodeme ...

Southern Medical Journal, 1981
A Laotian immigrant with persistent cough and hemoptysis was found to have multiple small cavities on chest roentgenogram. Ova of the lung fluke Paragonimus westermani were found in the sputum, and the patient responded to bithionol therapy. Pulmonary paragonimiasis should be considered in the differential diagnosis of cavitary lung disease in ...

Identification and characterization of Paragonimus westermani leucine aminopeptidase
Parasitology International, 2008Paragonimus westermani is a tissue-invading trematode parasite that causes inflammatory lung disease as well as systemic infections including cerebral invasion in carnivorous mammals. While aminopeptidases play important roles in trematodes in the catabolism of host hemoglobin, an essential source of nutrient for the parasite, little is known about ...

MOLECULAR CHARACTERIZATION OF TWO MYOGLOBINS OF PARAGONIMUS WESTERMANI
Journal of Parasitology, 2007Myoglobins (Mbs), globin proteins, are present in high concentrations in trematodes. In Paragonimus westermani, 2 cDNAs were found to encode Mbs. The first clone, Pwmyo1, codes a total of 149 amino acids with a calculated mass of 16.6 kDa. The second, Pwmyo2, encodes a 146-amino acid protein with a calculated mass of 16.2 kDa.

Treatment of Paragonimus Westermani Infections with Bithionol
The American Journal of Tropical Medicine and Hygiene, 1970Abstract Bithionol—2,2′thiobis(4,6-bichlorphenol)—was used for the mass treatment of 1,355 patients with proved infections with Paragonimus westermani. The dosage used was 40 mg per kg of body weight per day, on alternate days, for either 10 or 15 doses, but some patients took only 5 to 9 doses.

Ancient divergence of Paragonimus westermani in Sri Lanka
Parasitology Research, 2008Adult flukes of Paragonimus species were obtained from lungs of experimental animals infected with metacercariae found in field-collected freshwater crabs in Sri Lanka. Morphological studies of adult worms under a scanning electron microscope as well as a ordinary microscope were performed in the present study.

Genetic diversity in parthenogenetic triploid Paragonimus westermani
International Journal for Parasitology, 1999Paragonimus westermani is a medically important foodborne trematode occurring throughout southeast Asia. We have used molecular techniques to test the hypothesis that the parthenogenetic triploid form of P. westermani has arisen only once. Sources of data for comparison were: (a) restriction fragment length polymorphisms (RFLPs) of ribosomal internal ...

Chylothorax Caused by Paragonimus westermani in a Native Californian
Chest, 2011Paragonimiasis is a parasitic infection endemic in Asia but uncommon in the United States. It presents most frequently with cough and hemoptysis. Pleural effusions are common and can manifest occasionally as a pseudochylothorax, but a true chylothorax has, to our knowledge, never been reported.

Venison, another source of Paragonimus westermani infection
Parasitology International, 2016Paragonimiasis is a typical food-borne parasitic disease, endemic in most parts of Asia, with sporadic case reports from American and African countries. The major source of infection is undercooked freshwater crab or crayfish, though consumption of wild boar meat is also responsible for the infection in Japan, because wild boar is a paratenic host for ...
