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 retained in 40 and 20µm mesh sieves. DNA of the
taeniid eggs... 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
M. Larsen, J. Wolstrup, S A Henriksen, Carin Dackman, J. Grønvold, P. Nansen
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 selected isolates was tested in synthetic saliva,

Biological control ofOstertagia ostertagiby feeding selected nematode-trapping fungi to calves Tập 67 Số 1 - Trang 31-36 - 1993
J. Grønvold, J. Wolstrup, M. Larsen, S A Henriksen, P. Nansen
AbstractThree nematode-trapping fungi, oneArthrobotrys oligosporaand
twoDuddingtonia flagransisolates, were fed toOstertagia ostertagi-infected
calves to test their ability to destroy larvae of this parasite in faeces and
consequently to reduce the transmission of infective larvae to herbage. The
fungi had previously been selected for their capability to pass the alimentary
tract of cattle without... hiện toàn bộ
Observations on the morphology of adults and larval stages of Oesophagostomum sp. isolated from man in northern Togo and Ghana Tập 67 Số 1 - Trang 49-61 - 1993
J. Blotkamp, H. P. Krepel, V. Kumar, S. Baéta, J. M. Van't Noordende, A. M. Polderman
AbstractInfection with Oesophagostomum sp. appears to be extremely common in man
in northern Togo and Ghana Adult specimens were recovered from the intestinal
lumen by treatment with pyrantel pamoate and the morphological characteristics
of oesophagostomes of man could for the first time be compared with information
available on the morphology of oesophagostomes of monkeys. The observations and

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
R.S. Dai, G.H. Liu, Hui‐Qun Song, Rui-Qing Lin, Zi‐Guo Yuan, Mengxian Li, Si‐Yang Huang, Wei Liu, Xing‐Quan Zhu
AbstractSequence variability in two mitochondrial DNA (mtDNA) regions, namely
cytochromecoxidase subunit 1 (cox1) and NADH dehydrogenase subunit 4 (nad4), and
internal transcribed spacer (ITS) of rDNA among and within three
cestodes,Spirometra erinaceieuropaei,Taenia multicepsandTaenia hydatigena, from
different geographical origins in China was examined. A portion of thecox1
(pcox1),nad4 genes (p... hiện toàn bộ
The Physiological Ageing of Ancylostome Larvae Tập 17 Số 4 - Trang 195-202 - 1939
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.
Comparative Studies on the Characteristics of Some Geographical Strains of Schistosoma mansoni in Mice and Hamsters Tập 39 Số 1 - Trang 101-112 - 1965
M. F. A. Saoud
In the First Report of the W. H. O. Expert Committee on Bilharziasis (1953) it
was stated: “Infection with Schistosoma is often well tolerated and without
clinical signs, however this relative benignity appears to vary considerably
from country to country, without the cause of these variations being as yet
thoroughly understood”. This statement refers to the relative absence of serious
manifestati... hiện toàn bộ
