A reliable, rapid and low-cost method for drug sensitivity determination of Giardia duodenalis trophozoites (WB-strain) was developed in a 96-well plate. Using a standard inoculum of 5 x 10(4) trophozoites per well (300 microl), good growth was obtained after sealing the plate with an air-tight adhesive tape and incubation at 37 degrees C for 72 h in(More)
Establishing in vitro cultures of Giardia duodenalis trophozoites from faecal cysts remains very difficult due to poor excystation and bacterial contamination. This study investigated an alternative approach starting from duodenal trophozoites of gerbils that were artificially infected with field isolates from humans (Assemblages A and B) and cattle(More)
This study investigated the molecular and biological variation among different Giardia duodenalis assemblages. In vitro growth and susceptibility to albendazole, fenbendazole, flubendazole, metronidazole, tinidazole and furazolidone was studied for laboratory (AI: WB, AII: G1 and B: GS/M-83-H7) and 6 field isolates of assemblage subtype AI, AII, B and EIII.(More)
AIMS Development of the resazurin microplate method (RMM) as a novel test system for the evaluation of the antimicrobial activity of antiseptics and disinfectants. The validated RMM was subsequently applied for the evaluation of hydrogen peroxide (H(2)O(2)) and stabilized H(2)O(2) combination products. METHODS AND RESULTS The European Committee for(More)
This study investigated the significance of the genetic differences between assemblages A, B and E on intestinal growth and virulence. Intestinal growth and virulence were studied in 2 laboratory (A(I): WB and B: GS/M-83-H7) and 6 field isolates of assemblage subtype A(I), A(II), B and E(III). Intestinal trophozoite burdens, body weight and faecal(More)
The antigiardial effects of nitric oxide (NO⋅) have been reported in vitro, but only for assemblage AI lab strains. This study investigated the intrinsic NO⋅ susceptibility of different assemblage subtypes. The susceptibility (IC50) for NO⋅ released by MAHMA NONOate was studied for three lab (WB, G1 and GS/M-83-H7) and six field isolates of assemblage(More)
Giardia duodenalis is a protozoan parasite known to infect animals and humans. Zoonotic transmission of G. duodenalis can occur by the consumption of drinking water produced from surface water that is contaminated by runoff from manure-laden fields or pastures. Although it was previously reported that storing solid cattle manure decreases G. duodenalis cyst(More)
