Transfusion
. 2014 Mar;
54(9):2217-25.
PMID: 24673297
Background: Babesia infection is caused by intraerythrocytic tick-borne parasites. Cases of transfusion-transmitted babesiosis have been increasingly recognized. To date, no Babesia test has been licensed for screening US blood donors....

. 2013 Jan;
31(8):506-10.
PMID: 23273661
Molecular PCR based diagnostic techniques have enabled us to distinguish between the different, morphologically identical, Cryptosporidium species that can infect humans. Of the 23 recognized species in the genus, at...

Transfusion
. 2011 Dec;
52(7):1517-22.
PMID: 22168221
Background: Almost all of the reported US tick-borne and transfusion-associated Babesia cases have been caused by Babesia microti, which is endemic in the Northeast and upper Midwest. We investigated a...

PMID: 21888805
The Phylum Microsporidia comprises >1,200 species, only 15 of which are known to infect humans, including the genera Trachipleistophora, Pleistophora, and Brachiola. We report an infection by Tubulinosema sp. in...

. 2011 Jul;
49(9):3143-9.
PMID: 21752983
Isoenzyme analysis of cultured parasites is the conventional approach for Leishmania species identification. Molecular approaches have the potential to be more sensitive and rapid. We designed PCR generic primers to...

J Parasitol
. 2008 Mar;
93(6):1536-8.
PMID: 18314710
Species of Cryptosporidium infect a broad variety of animals. Because morphological features of the secreted oocysts are not useful in identifying the parasite at the species level, molecular tools were...
