Laboratory diagnosis of autoinfection in strongyloidiasis.
TLDR
It was concluded that only two of the cases were true autoinfections, and the other two apparent cases resulted from prolonged storage of unrefrigerated stools in the hospital ward. Expand
Human echinostomiasis: mechanisms of pathogenesis and host resistance.
TLDR
Human echinostomiasis, caused by about 20 species belonging to eight genera, is considered a zoonosis and the natural definitive hosts may also serve as reservoirs for human infection. Expand
Laboratory Rearing of Biomphalaria glabrata Snails and Maintenance of Larval Schistosomes In Vivo and In Vitro
TLDR
The goal of this chapter is to aid researchers who have the need or desire to maintain the life cycle of this pulmonate and its trematode parasites in the laboratory with particular emphasis on the optimal physical, chemical, and biological factors that affect successful snail rearing and/or breeding. Expand
Schistosoma mansoni: in vitro conversion of cercariae to schistosomula.
TLDR
Investigation of cercariae in rat chamber fluid resulted in organisms which were water sensitive, but retained their tails and pre-acetabular gland contents, and conversion to water sensitivity was not blocked by 0-01 M EDTA. Expand
Two cases of enteric myiasis in man. Pseudomyiasis and true intestinal myiasis.
TLDR
Dipterous larvae were found in the appendices from two postmortem examinations, believed to be a case of "pseudomyiasis", i.e., the accidental entrapment of a swallowed larva passing through the digestive tract. Expand
Schistosoma mansoni: complement and cercarial tail loss during in vitro transformation.
TLDR
In the present studies, tail loss during in vitro conversion was shown to be complement dependent and the extent and rate of tail loss was normal in agammaglobulinemic sera indicating that the complement effect was not antibody dependent. Expand
Schistosoma mansoni: chemoreception through n-acetyl-d-galactosamine-containing receptors in females offers insight into increased severity of schistosomiasis in individuals with blood group A.
TLDR
Data suggest that GalNAc-containing receptors, possibly GP50, the major SBA-binding schistosome glycan, mediate chemoreception in Schistosoma mansoni females, and may explain the observed differences in morbidity between individuals with different blood groups. Expand
Schistosoma mansoni: long-term maintenance of clones by microsurgical transplantation of sporocysts.
TLDR
The results clearly demonstrate that the microsurgical transplantation of sporocysts is a practical means of maintaining and expanding populations of genetically homogeneous schistosomes (clones). Expand
