Tetrodotoxin (TTX) and its analogue 6-epiTTX had been detected in the red-spotted newt, Notophthalmus viridescens. Thirty specimens of a population from Pennsylvania, USA were histologically examined for the presence of intestinal parasites. More than 50% were found to be infected with nematodes (Trichocephalidae), trematodes or cestodes (Pseudophyllidae). The mean values of TTX and 6-epiTTX in parasitized...
The method of membrane filtration was evaluated regarding the recovery efficiency of Giardia cysts and Cryptosporidium oocysts from water. Equal volumes of distilled water were contaminated with a defined numbers of cysts and oocysts (1 10 2 , 1 10 3 , 5 10 3 and 1 10 4 parasites 1 -1 ) and filtered through a special membrane filter apparatus...
P. carinii is the most important opportunistic pathogen causing severe and often fatal infection in the immunocompromised host. Certain parts of the life cycle are still undetermined, including the existence and the fusion of gametes, the course of meiosis and the fate of the meiotic products. We studied the different developmental stages of P. carinii cytophotometrically, using Schiffs reagent as...
