displacement of biomphalaria glabrata by the snail thiara granifera in field habitats in st. lucia, west indies. | thiara granifera is a melaniid snail capable of maintaining very high densities in a variety of habitats. it has been introduced into the new world from the far east and is now spreading rapidly throughout the caribbean. in puerto rico and dominica casual observations following natural invasion by t. granifera suggest that it may exert a powerful restraining influence on populations of biomphalaria glabrata, the major intermediate host of schistosoma mansoni in the caribbean. the potential of t. ... | 1983 | 6882056 |
ultrastructural investigations on the effects of praziquantel on human trematodes from asia: clonorchis sinensis, metagonimus yokogawai, opisthorchis viverrini, paragonimus westermani and schistosoma japonicum. | the effect of praziquantel (biltricide) on the ultrastructure of trematodes pathogenic to man in asia was investigated in: clonorchis sinensis, opisthorchis viverrini, schistosoma japonicum, metagonimus yokogawai, and paragonimus westermani. the different parasites were isolated from their respective experimental hosts and uniformly incubated for 5, 15, 30 or 60 min at 37 degrees c in medium tc 199 containing 0, 1, 10 or 100 micrograms praziquantel/ml. all parasites exposed to praziquantel were ... | 1983 | 6338885 |
the antigens of paragonimus westermani, schistosoma mansoni, and fasciola hepatica adult worms. evidence for the presence of cross-reactive antigens and for cross-protection to schistosoma mansoni infection using antigens of paragonimus westermani. | the presence of cross-reacting antigens between paragonimus westermani, schistosoma mansoni, and fasciola hepatica adult worms was demonstrated by ouchterlony immunodiffusion and enzyme-linked immunosorbent assay (elisa). a serum bank was developed against the three trematode genera to serve as probes to determine the presence of cross-reacting antibodies to p. westermani worm extracts. in this manner, it was possible to demonstrate that antigens common to f. hepatica and s. mansoni tegument wer ... | 1983 | 6404188 |
studies on the geographical distribution of the lung fluke, paragonimus westermani (kerbert, 1878) in the southern prefectures of the kinki district, japan: observations on the incidence of encysted larvae of p. westermani in geothelphusa dehaani in higashi-yoshino area, nara prefecture. | 1983 | 6632458 | |

the measurement of ascaris suum protein by radioimmunoassay in sera from patients with helminthiasis and with gastrointestinal diseases. | in this study, we have developed a reliable radioimmunoassay (ria) for ascaris suum protein (asp) and have measured the serum concentration of asp in control subjects and in patients with helminthiasis and a variety of gastrointestinal diseases. the cross-reactivities of asp antibody with other helminth worm antigens were also measured by ria. ascaris lumbricoides contained approximately the same amount of asp antigenic substance as did ascaris suum. toxocara canis had a high concentration of a ... | 1983 | 6682964 |
intraocular paragonimiasis. | a case of intraocular paragonimiasis is reported in a 13-year-old chinese boy. the disease manifested as repeated attacks of acute intraocular pain associated with panuveitis. a combination of inflammatory reaction and ocular findings mimicking both perforating and contusion injuries caused by the migration of the fluke within the eye characterises the infection. the living fluke was successfully extracted from the anterior chamber and identified as paragonimus westermani. | 1984 | 6691960 |
a survey of parasitic lesions in wild-caught, laboratory-maintained primates: (rhesus, cynomolgus, and baboon). | the lesions associated with parasitic infestation in 1156 wild-caught, laboratory-maintained nonhuman primates (macaca fascicularis, macaca mulatta, and papio spp) are described. the two most common parasites seen were lung mites (pneumonyssus spp) and nodular worms (oesophagostomum spp). in addition, in cynomolgus monkeys (macaca fascicularis) only, nochtia nochti was a frequent pathogen. the etiology of mineralized fibrotic nodules in the mesentery of cynomolgus monkeys was thought to be infec ... | 1984 | 6730203 |

[surgical treatment of cerebral paragonimiasis miyazakii]. | an operated case of cerebral paragonimiasis miyazakii was reported. a 25-year-old man was admitted to our hospital on jan. 25, 1982, because of weakness, sensory disorder and focal convulsion of the right upper limb. he complained of slight headache but had no sign of meningeal irritation nor inflammation. ct scan revealed a left parietal low density mass with irregular ring-like contrast enhancement. left carotid angiogram showed stretched arteries around the mass. laboratory findings were norm ... | 1984 | 6483096 |
paragonimus westermani: life cycle, intermediate hosts, transmission to man and geographical distribution in korea. | since discovery of this lung fluke in 1878 by kerbert, paragonimus westermani has been found to occur in many parts of asia. recently, however, it was detected that there exists a bisexual type and also a parthenogenetic type of the lung fluke which has been called p. westermani for a century. the natural definitive hosts other than man include a wide range of mammals. adult worms are localized in the lungs. the eggs excreted with sputum and reaching water develop into miracidia in water. miraci ... | 1984 | 6542389 |
paragonimus westermani: pathogenesis and clinical features of infection. | pathogenesis: although the pathogenesis of human infection of p. westermani is not fully elucidated, experimental infections of cats or dogs could explain the early phase of paragonimiasis. as the larvae of p. westermani penetrate the intestinal wall and localize in the peritoneal cavity there appears to be a considerable migration inside the abdominal cavity before they direct toward the chest cavity through the diaphragm. approximately 20 days following experimental infection with metacercaria ... | 1984 | 6542390 |
paragonimiasis in the philippines: current status. | paragonimiasis in the philippines was first reported in 1907. the first attempt to study its life cycle was made in 1941 when metacercariae of paragonimus were found in fresh-water mountain crabs. at present the causative agent of human paragonimiasis in this country is paragonimus westermani, although the new name, paragonimus philippinensis, has been proposed instead. the second species of paragonimus, paragonimus siamensis, was reported in cats in 1973. the prevalence of disease in two endemi ... | 1984 | 6542392 |
paragonimiasis: experimental and clinical experience with praziquantel in korea. | the effect of praziquantel (2-cyclohexylcarbonyl-1,2,3,6,7,11b-hexahydro-4h-pyrazino[2,1-a]++ +isoquinolin- 4-one, embay 8440, biltricide) on the ultrastructure of paragonimus westermani was investigated in vitro and in vivo. in in vitro experiments, p. westermani was less sensitive to praziquantel. only very few vacuoles were formed in the tegumental syncytium after incubation in 100 micrograms/ml for 60 min. however, in vivo the parasite was successfully destroyed by praziquantel. in fine stru ... | 1984 | 6542393 |
observation of paragonimus westermani eggs in sputum after digestion for mycobacteria culture. | pulmonary paragonimiasis was diagnosed by the observation of paragonimus westermani eggs on smears of sputum concentrated for the detection of mycobacteria and on the culture plates. the eggs were distorted but recognizable. | 1984 | 6435946 |
immunity of schistosomes using heterologous trematode antigens--a review. | this review summarizes the field of cross-protection in schistosomiasis due to other parasitic infections and with subcellular fractions of the parasite trematodes. regarding parasitic infections, the clearest evidence of cross-protection to schistosoma mansoni was found with the trematodes, particularly with fasciola hepatica. evidence was also presented which demonstrated that the protective f. hepatica worm antigens were those which bound to antibodies to s. mansoni, and that as antigen purif ... | 1984 | 6382782 |
