NMBU NMBU PO box 369 sentrum NORWAY Oslo ----- Select State ----- 0102 +4767232299.

Berries are potential vehicles for the transmission of parasites and have been implicated in illness outbreaks in various countries around the world, particularly in the USA. Although data on contamination of fresh produce with foodborne parasites have been obtained from different global regions, data from Colombia are lacking despite South America being a major producer of fresh produce, which is consumed both nationally and exported. In this study, we used a previously published multiplex qPCR approach for investigating contamination of strawberries purchased in either supermarkets or local markets from each of the 20 localities.

Comparison of commercial and in-house real-time PCR platforms for 15 parasites and microsporidia in human stool samples without a gold standard.

Acta Trop 2020 May 3;207:105516. Epub 2020 May 3.

Institute for Medical Microbiology, Virology and Hygiene, University Medicine Rostock, Rostock, Germany; Department of Microbiology and Hospital Hygiene, Bundeswehr Hospital Hamburg, Hamburg, Germany. Electronic address:

Introduction: A test comparison of in-house and commercial real-time PCR (qPCR) kits for the detection of human parasites and microsporidia in stool samples was conducted without a gold standard. Three different commercial kits were included in the comparison, with a range of 3-15 different PCR targets, while 14 targets were covered by in-house testing, so not all 16 target pathogens were covered by all assays.

Methods: Residual materials from nucleic acid extractions of stool samples with very high likelihood of being colonized or infected by at least one enteric parasite species or microsporidia were tested. Read More

Genotyping genetically heterogeneous infections to complement epidemiological case linkage.

Parasitology 2019 09 20;146(10):1275-1283. Epub 2019 Jun 20.

Malaria Branch, Division of Parasitic Diseases and Malaria, Center for Global Health, Centers for Disease Control and Prevention, Atlanta, Georgia, USA.

Sexually reproducing pathogens such as Cyclospora cayetanensis often produce genetically heterogeneous infections where the number of unique sequence types detected at any given locus varies depending on which locus is sequenced. The genotypes assigned to these infections quickly become complex when additional loci are analysed. This genetic heterogeneity confounds the utility of traditional sequence-typing and phylogenetic approaches for aiding epidemiological trace-back, and requires new methods to address this complexity.
