Microb Genom . 2023 Mar; 9(3). PMID: 36976254
(syn. ) is a widespread gastrointestinal protozoan parasite with debated taxonomic status. Currently, eight distinct genetic sub-groups, termed assemblages A-H, are defined based on a few genetic markers. Assemblages A...

Parasit Vectors . 2022 Dec; 15(1):489. PMID: 36572928
Background: The flagellated parasite Giardia duodenalis is a major and global cause of diarrhoeal disease. Eight genetically very distinct groups, known as assemblages A to H, have been recognized in...

Euro Surveill . 2021 Nov; 26(44). PMID: 34738516
IntroductionThe detection of SARS-CoV-2 with rapid diagnostic tests (RDT) has become an important tool to identify infected people and break infection chains. These RDT are usually based on antigen detection...

von Laer A, NGuessan M, Toure F, Nowak K, Groeschner K, Ignatius R, et al.
Front Med (Lausanne) . 2021 Jun; 8:627513. PMID: 34095162
Blood cultures (BC) have a high clinical relevance and are a priority specimen for surveillance of antimicrobial resistance. Manual BC are still most frequently used in resource-limited settings. Data on...

Woschke A, Faber M, Stark K, Holtfreter M, Mockenhaupt F, Richter J, et al.
PLoS Negl Trop Dis . 2021 Mar; 15(3):e0009277. PMID: 33764999
Background: Giardia duodenalis is a leading cause of gastroenteritis worldwide. Humans are mainly infected by two different subtypes, i.e., assemblage A and B. Genotyping is hampered by allelic sequence heterozygosity...

Bruckner V, Fiebiger U, Ignatius R, Friesen J, Eisenblatter M, Hock M, et al.
Gut Pathog . 2020 Apr; 12:21. PMID: 32322308
Background: species, particularly , but also constitute emerging pathogens causing gastroenteritis in humans. However, isolation of may often fail during routine diagnostic procedures due to the lack of standard protocols....

Gut Pathog . 2020 Jan; 12:3. PMID: 31921357
Background: constitute emerging food- and waterborne pathogens causing gastroenteritis in humans, but the underlying mechanisms are only incompletely understood. We therefore characterized isolates derived from human stool samples that had...
