An improved test system for PCR-based specific detection ofEchinococcus multiloculariseggs Tập 70 Số 3 - Trang 219-222 - 1996
Alexander Mathis, Peter Deplazes, J. Eckert
AbstractFor the sensitive detection of eggs ofEchinococcus multilocularisin fox faeces by PCR we have evaluated a method based on the previous concentration of helminth eggs by a combination of sequential sieving of faecal samples and flotation of the eggs in zinc chloride solution. The eggs were microscopically detected in the fractions ...... hiện toàn bộ In vitro stress selection of nematophagous fungi for biocontrol of parasitic nematodes in ruminants Tập 65 Số 3 - Trang 193-200 - 1991

ABSTRACTLaboratory experiments were designed to select nematophagous fungi that were able to survive in vitro conditions simulating passage through the gastro-intestinal tract of cattle. All of the tests were conducted at 39°C. In a primary stress selection step in diluted rumen fluid, 21 isolates were obtained. Each of the primary stress...... hiện toàn bộ Sequence variability in two mitochondrial DNA regions and internal transcribed spacer among three cestodes infecting animals and humans from China Tập 86 Số 2 - Trang 245-251 - 2012

W. P. Rogers
The activity, infectivity and fat content of ageing infective larvae of Ancylostoma caninum were investigated at regular intervals.The reduction in activity and fat content was found to occur at a similar rate.
