Complete development and multiplication of Cryptosporidium hominis in cell-free culture.
The present study reports for the first time the completion of the life cycle of Cryptosporidium hominis in cell-free culture and multiplication of the parasite via qPCR. Individual life-cycle stages were characterised using Cryptosporidium-specific antibody staining (Sporo-Glo) and fluorescent in situ hybridisation (FISH) staining on cultures inoculated with excysted oocysts and purified sporo...
متن کاملComplete development of Cryptosporidium parvum in host cell-free culture.
The present study describes the complete in vitro development of Cryptosporidium parvum (cattle genotype) in RPMI-1640 maintenance medium devoid of host cells. This represents the first report in which Cryptosporidium is shown to multiply, develop and complete its life cycle without the need for host cells. Furthermore, cultivation of Cryptosporidium in diphasic medium consisting of a coagulate...
متن کاملComparison of various staining methods for the detection of Cryptosporidium in cell-free culture.
The complete development of Cryptosporidium in host cell-free medium first described in 2004, represented a significant advance that can facilitate many aspects of Cryptosporidium research. A current limitation of host cell-free cultivation is the difficulty involved in visualising the life-cycle stages as they are very small in size, morphologically difficult to identify and dispersed througho...
متن کاملHighly Efficient In Vitro Production of Bovine Blastocyst in Cell-Free Sequential Synthetic Oviductal Fluid vs. TCM199 Vero Cell Co-Culture System
Background The aim of this study was to establish a cell-free sequential culture system that can support high levels of in vitro embryo development and blastocyst formation from bovine zygotes. To this end, this investigation was carried out to evaluate the effects of glucose, serum and EDTA on bovine zygote in vitro development. MaterialsAndMethods Bovine presumptive zygotes were derived from ...
متن کاملPoint prevalence of Cryptosporidium, Cyclospora, and Isospora infections in patients being evaluated for diarrhea.
From March to September 2001, 315 specimens from "nonrepeat" patients that were submitted for ova and parasite examination were stained using the Kinyoun modified acid-fast stain to detect the intestinal coccidians. Four patients (1.3%) were infected with coccidians, 2 with Cryptosporidium parvum and 2 with Cyclospora cayetanensis. No infections with Isospora belli were detected. In comparison,...
