Excretory bladder: the source of cysteine proteases in Paragonimus westermani metacercariae.
The cysteine proteases of Paragonimus westermani metacercariae are involved in metacercarial excystment, host immune modulation, and possibly in tissue penetration. In order to clarify the origin of the enzymes, 28 and 27 kDa cysteine proteases in metacercarial excretory-secretory products were purified through the FPLC system using Mono Q column chromatography. The polyclonal antibodies to the...
متن کاملInfection status of freshwater crabs and crayfish with metacercariae of Paragonimus westermani in Korea.
The present study investigated the infection status of Paragonimus westermani metacercariae in freshwater crabs (n = 363) and crayfish (n = 31) from October 2007 to October 2008 using the crush method. All of the freshwater crabs, Eriocheir japonicus, were negative for P. westermani metacercariae while 10 (32.3%) of the 31 examined crayfish were positive. The 10 positive crayfish were caught in...
متن کاملMolecular discrimination between individual metacercariae of Paragonimus heterotremus and P. westermani occurring in Thailand.
To accurately discriminate between individual metacercariae of Paragonimus heterotremus and P. westermani occurring in Thailand, polymerase chain reaction (PCR)-based molecular methods were established and subjected to an evaluation. We first amplified and sequenced the second internal transcribed spacer (ITS2) region of the nuclear ribosomal DNA of the two species. Based on their nucleotide di...
متن کاملCloning and expression of a cysteine proteinase gene from Paragonimus westermani adult worms.
A gene encoding a cysteine proteinase from Paragonimus westermani has been cloned and expressed in Escherichia coli. The cysteine proteinase cDNA fragment was amplified by reverse transcription-polymerase chain reaction (RT-PCR) using degenerate oligonucleotide primers derived from the conserved active site of the cysteine proteinase. The 5' and 3' regions of the gene were amplified using a PCR...
متن کاملParagonimus westermani found in the tip of a little finger.
Paragonimiasis is the infestation of lung flukes of the trematode genus Paragonimus. Because the symptoms and radiologic findings of paragonimiasis mimic those of tuberculosis, some patients with paragonimiasis are initially treated for tuberculosis. Although Paragonimus may also reach ectopic sites such as the peritoneum or brain, infection in the skin is rare. To our knowledge, paragonimiasis...
