Journal ArticleDOI
Dominance of Giardia assemblage B in León, Nicaragua.
Marianne Lebbad,Johan Ankarklev,Aleyda Tellez,Byron Leiva,Jan Andersson,Staffan G. Svärd,Staffan G. Svärd +6 more
TL;DR: A molecular analysis of Giardia isolates from humans and dogs living in the same area in León, Nicaragua was performed, finding mixed infections between assemblage A and B were found when the gdh gene was analyzed.
Journal ArticleDOI
Common coinfections of Giardia intestinalis and Helicobacter pylori in non-symptomatic Ugandan children.
Johan Ankarklev,Elin Hestvik,Marianne Lebbad,Johan Lindh,Deogratias H Kaddu-Mulindwa,Jan Andersson,Thorkild Tylleskär,James K Tumwine,Staffan G. Svärd +8 more
TL;DR: It is shown that Giardia assemblage B dominates in children in Kampala, Uganda and that the presence of H. pylori is an associated risk factor for G. intestinalis infection.
Journal ArticleDOI
Transcriptome profiling of Giardia intestinalis using strand-specific RNA-seq.
Oscar Franzén,Jon Jerlström-Hultqvist,Elin Einarsson,Johan Ankarklev,Marcela Ferella,Björn Andersson,Staffan G. Svärd +6 more
TL;DR: In this article, the authors compared the polyadenylated transcriptomes of assemblages A, B and E using paired-end, strand-specific RNA-seq and revealed many examples of conserved and unexpectedly long 3' UTRs.
Journal ArticleDOI
Allelic sequence heterozygosity in single Giardia parasites
TL;DR: Micromanipulation results conclusively show that ASH does occur at the single cell level in assemblage B Giardia, and illuminates the necessity of developing new G. intestinalis genotyping tools.
Journal ArticleDOI
Synchronisation of Giardia lamblia: identification of cell cycle stage-specific genes and a differentiation restriction point.
David S. Reiner,Johan Ankarklev,Karin Troell,Daniel Palm,Rolf Bernander,Frances D. Gillin,Jan Andersson,Staffan G. Svärd,Staffan G. Svärd +8 more
TL;DR: It is reported that Giardia isolates of the major human genotypes A and B can be synchronised using aphidicolin, a mycotoxin that reversibly inhibits replicative DNA polymerases in eukaryotic cells.
