RFB-1 is a monoclonal antibody previously shown to react with granulocyte-monocyte progenitors (CFU-GM) and immature lymphoid cells in human bone marrow. RFB-HLA-DR is a monoclonal antibody that reacts with HLA-DR (la-like) antigens. The present study shows that the bone marrow subset reactive with both RFB-1 and RFB-HLA-DR contains all the cells that give rise to mixed hematopoietic colonies (...
Deficiency of decay-accelerating factor (DAF) occurs in blood cells in paroxysmal nocturnal hemoglobinuria (PNH), characterized by an unusual susceptibility to hemolysis by complement activation. This study examined DAF expression on hematopoietic progenitors from normal individuals and PNH patients using a fluorescence-activated cell sorter (FACS) with monoclonal antibodies to DAF. Nonphagocyt...
The erythrocyte colony-forming unit (CFU-E) is a rare bone marrow (BM) progenitor that generates erythrocyte colonies in 48 hours. The existence of CFU-Es is based on these colonies, but CFU-Es have not been purified prospectively by phenotype. We have separated the "nonstem," "nonlymphoid" compartment (lineage marker [lin]-c-Kit+Sca-1-IL-7Ralpha-) into interleukin 3 receptor alpha negative (IL...
An in vitro clonal assay for a class of human hemopoietic progenitors (CFU-GEMM) with several characteristics of pluripotential stem cells has been previously described. In the presence of medium conditioned by leukocytes stimulated with phytohemagglutinin (PHA-LCM) and erythropoietin (Ep), CFU-GEMM give rise to mixed hemopoietic colonies containing granulocytic, erythroid, monocyte-macrophage,...
9 Most probable number (MPN) and colony-forming-unit (CFU) estimates of fecal 10 coliform bacteria concentration are common measures of water quality in coastal 11 shellfish harvesting and recreational waters. Estimating procedures for MPN and 12 CFU have intrinsic variability and are subject to additional uncertainty arising from 13 minor variations in experimental protocol. It has been observ...
OBJECTIVES Swabs are widely used to collect samples for microbiological analyses from various clinical settings. They vary by material, size, and structure of the tip. This study investigates the uptake and release capacities for liquid and bacteria. METHODS Five swabs were analyzed for their uptake and release capacities of Staphylococcus aureus and Staphylococcus epidermidis suspensions. Tw...
We sequenced and compared the genomes of the Dothideomycete fungal plant pathogens Cladosporium fulvum (Cfu) (syn. Passalora fulva) and Dothistroma septosporum (Dse) that are closely related phylogenetically, but have different lifestyles and hosts. Although both fungi grow extracellularly in close contact with host mesophyll cells, Cfu is a biotroph infecting tomato, while Dse is a hemibiotrop...
