One hundred and forty-four samples of chilled turkey meat from six flocks, taken directly from the slaughterhouse, and 100 samples of turkey meat retail products were examined. Over one-quarter (29.2%) of the tested samples from the slaughterhouse were Campylobacter positive, showing high variability in the flocks. The lowest percentage of Campylobacter-positive samples was found in flocks I an...

Escherichia coli is divided into four main phylogenetic groups, which each exhibit ecological specialization. To understand the population structure of E. coli in its primary habitat, we directly assessed the relative proportions of these phylogroups from the stools of 100 healthy human subjects using a new real-time PCR method, which allows a large number of samples to be studied. The detectio...

(a) Dose. These standards are based on (1) vaccine intended for intradermal injection in a single human immunizing dose of 0.1 milliliter and (2) vaccine intended for percutaneous injection in a single skin application through which inoculation is made by a multiple puncture device. (b) Date of manufacture. The date of manufacture is the date of initiation of the last valid determination for CF...

introduction: endothelial progenitor colony forming unit-endothelial cells (cfu-ec) were first believed to be the progenitors of endothelial cells, named endothelial progenitor cells. further studies revealed that they are monocytes regulating vasculogenesis. the main hindrance of these cells for therapeutic purposes is their low frequency and limited replicative potentials. this study was unde...

Androgens remain a common treatment for certain type of anemia, based upon its myelostimulating effects; however, it has not been established whether androgens affect apoptosis of hematopoietic progenitor cells (HPCs). We investigated the effects of the androgens, such as testosterone, 5beta-dihydrotestosterone (5-DHT), and oxymetholone, on apoptosis of normal hematopoietic progenitor cells in ...

Public libraries are popular gathering places, so understanding the factors that contribute to colony-forming unit (CFU) concentrations and how minimize them is essential. This study aimed investigate affect CFU in a public library, using air sampling (Bioluminescent ATP-assay) statistical analysis software (SPSS) collect analyze data. The findings indicated concentration library was significan...

We studied the effects of yeast in peripheral blood samples on results reported by an ADVIA 120/2120 Hematology System (Bayer HealthCare, Diagnostics Division, Tarrytown, NY). In a simulated candidemia model, very high concentrations (1-5 x 10(8) colony-forming units [CFU]/mL) of Candida glabrata and Candida parapsilosis caused a spuriously elevated platelet count. No such effect was observed w...

Campylobacter are important human foodborne pathogens known to colonize the gastrointestinal tract of cattle. The incidence of Campylobacter in cattle may be seasonal and may vary among age groups and type (beef versus dairy). Less is known about other factors that could influence the prevalence, colonization site, and shedding of Campylobacter in cattle. The objectives of this study were to ev...

Acute myeloid leukemia (AML) is a clonal disease characterized by heterogeneous involvement of hematopoietic stem cell/progenitor cell populations. Using FLT3 internal tandem duplication (FLT3/ITD) as a molecular marker, we tested the hypothesis that clinical outcome in AML correlates with disease involvement of CD34(+)/CD33(-) precursors. Diagnostic specimens from 24 children with FLT3/ITD-pos...

The hematopoietic stimulatory activities of human recombinant IL-3 and granulocyte-macrophage colony stimulating factor (GM-CSF) were directly compared using highly enriched human bone marrow progenitor target cells. IL-3 supported a larger number of erythroid and megakaryocytic progenitor cells than did GM-CSF, while GM-CSF supported more myeloid progenitors. IL-3 directly stimulated the divis...
