NK cells are key effectors of innate immunity and host survival during cytomegalovirus (CMV) infection. Innate murine CMV (MCMV) resistance in MA/My mice requires Ly49H/m157-independent H-2k-linked NK cell control. Here we show that replacement of MA/My H-2k with C57L H-2b susceptibility genes led to a remarkable loss of innate virus immunity, though NK… (More)
Ribosomes, the protein factories of living cells, translate genetic information carried by messenger RNAs into proteins, and are thus involved in virtually all aspects of cellular development and maintenance. The few available structures of the eukaryotic ribosome reveal that it is more complex than its prokaryotic counterpart, owing mainly to the presence… (More)
The appropriate treatment and control of infectious gastroenteritis depend on the ability to rapidly detect the wide range of etiologic agents associated with the disease. Clinical laboratories currently utilize an array of different methodologies to test for bacterial, parasitic, and viral causes of gastroenteritis, a strategy that suffers from poor… (More)
Entamoeba histolytica is the cause of amebic colitis and liver abscess. This parasite induces apoptosis in host cells and utilizes exposed ligands such as phosphatidylserine to ingest the apoptotic corpses and invade deeper into host tissue. The purpose of this work was to identify amebic proteins involved in the recognition and ingestion of dead cells. A… (More)
Entamoeba histolytica contains a large and novel family of transmembrane kinases (TMKs). The expression patterns of the E. histolytica TMKs in individual trophozoites and the roles of the TMKs for sensing and responding to extracellular cues were incompletely characterised. Here we provide evidence that single cells express multiple TMKs and that TMK39 and… (More)
The FilmArray® Blood Culture Identification (BCID) panel was recently implemented at a midwestern academic tertiary care hospital to provide rapid identification (ID) of common pathogens from positive blood cultures. This study evaluated the clinical performance of the BCID panel compared to culture-based ID methods. One hundred thirty-eight monomicrobial… (More)
The Nebraska Medical Center (TNMC) was conducting an Institutional Review Board 8 approved research study utilizing the BioFire FilmArray Gastrointestinal Panel (BioFire 9 Diagnostics, Salt Lake City, UT) when an outbreak of cyclosporiasis occurred in Iowa and 10 Nebraska (1). The FilmArray GI Panel is a culture-independent molecular test that 11… (More)
Effective diagnostic tools are essential in order to combat disease caused by the parasite Entamoeba histolytica. In this study, we compared the commercially available Ridascreen Entamoeba test (R-Biopharm) and the E. histolytica II test (Techlab), and we found that the E. histolytica II test detects E. histolytica infections more accurately.
Microbacterium species are non-spore-forming, Gram-positive rods rarely associated with human disease. In this report, we describe the first case of bacteremia caused by Microbacterium binotii in a patient with sickle cell anemia. The utility of using 16S rRNA gene sequence analysis along with phenotypic methods for identification is shown.
The single-celled parasite, Entamoeba histolytica, is an enteric pathogen that ingests bacteria and host cells. Inhibition of phagocytosis renders the parasite avirulent. The ligand/receptor interactions that allow E. histolytica to phagocytose are not well understood. We hypothesised that E. histolytica trophozoites might accomplish ingestion through the… (More)
