Discrimination between viable and dead Encephalitozoon cuniculi (Microsporidian) spores by dual staining with sytox green and calcofluor white M2R.
Microsporidia are obligate intracellular parasites, recognized as causing chronic diarrhea and systemic disease in AIDS patients, organ transplant recipients, travelers, and malnourished children. Species of microsporidia that infect humans have been detected in drinking-water sources, and methods are needed to ascertain if these microsporidia are viable and capable of causing infections. In th...
متن کاملCytokine response to infection with the microsporidian, Encephalitozoon cuniculi.
The production of three cytokines, interferon gamma (IFN-gamma), interleukin 10 (IL-10) and interleukin 12 (IL-12), was measured after intraperitoneal infection of immunocompetent Balb/c mice and immunodeficient SCID mice with the microsporidian, Encephalitozoon cuniculi Levaditi, Nicolau et Schoen, 1923. High levels of IFN-gamma were detected in ex vivo cultures of peritoneal exudate cells (PE...
متن کاملDifferentiation between Viable and Dead Cryptosporidium Oocysts Using Fluorochrome Staining.
The use of nucleic acid staining with a fluorochrome dye to differentiate viable and dead (heat-killed) Cryptosporidium oocysts was assessed. The specificities (percentage of unstained viable oocysts) and sensitivities (percentage of stained dead oocysts) of the seven tested dyes (SYTO-17® and SYTO-59® to 64®) ranged from 65 to 76% (average 71%) and 83 to 95% (average 91%), respectively. SYTO-5...
متن کاملMetabolism of an alkyl polyamine analog by a polyamine oxidase from the microsporidian Encephalitozoon cuniculi.
Encephalitozoon cuniculi is a microsporidium responsible for systemic illness in mammals. In the course of developing leads to new therapy for microsporidiosis, we found that a bis(phenylbenzyl)3-7-3 analog of spermine, 1,15-bis{N-[o-(phenyl)benzylamino}-4,12-diazapentadecane (BW-1), was a substrate for an E. cuniculi amine oxidase activity. The primary natural substrate for this oxidase activi...
متن کاملIn vitro effects of resveratrol on the viability and infectivity of the microsporidian Encephalitozoon cuniculi.
Microsporidians of the genus Encephalitozoon are an important cause of disease in immunocompromised patients, and there are currently no completely effective treatments. The present study investigated the viability and infectivity of spores of Encephalitozoon cuniculi that had been exposed to resveratrol (RESV), a natural phytoalexin found in grapes and red wine. RESV at 50 microM showed signif...
