OBJECTIVE To examine the relation between parent expectations for antibiotics, parent communication behaviors, and physicians' perceptions of parent expectations for antibiotics. STUDY DESIGN A nested cross-sectional study with parallel measures of parents presenting children for acute respiratory infections (previsit) and physicians (postvisit) and audiotaping of the encounters. POPULATION...
The nucleotide sequence of a 7-kilobase segment of the Bacillus subtilis chromosome containing the entire coding regions for the enzymes catalyzing the first three steps of diaminopimelate synthesis as well as dipicolinate synthase has been determined. This group of functionally related genes, termed the dap operon, were arranged in the order orfY, orfX, asd, dapG, and dapA and were bracketed b...
Particular groups of plant-beneficial fluorescent pseudomonads are not only root colonizers that provide plant disease suppression, but in addition are able to infect and kill insect larvae. The mechanisms by which the bacteria manage to infest this alternative host, to overcome its immune system, and to ultimately kill the insect are still largely unknown. However, the investigation of the few...
OBJECTIVE To determine whether microcytic erythrocytes influence the accuracy of automated platelet (PLT) counting. METHODS We divided a total of 206 K2 ethylenediaminetetraacetic acid (EDTA)-anticoagulated blood samples into 4 groups, as follows: In group 1 (control group), normal mean corpuscular volume (MCV > 80 fL) and PLT count equal or greater than 140,000/microL (n = 45); group 2, norm...
Secondary metabolism in fluorescent pseudomonads is globally regulated by gacS, which encodes a membrane-bound sensor kinase, and gacA, which encodes a transcriptional response regulator. Spontaneous mutation in either gene blocked biosynthesis of the antimicrobial compounds hydrogen cyanide, 2,4-diacetylphloroglucinol, pyoluteorin, and pyrrolnitrin by the model biocontrol strain Pseudomonas fl...
ABSTRACT Strains of fluorescent Pseudomonas spp. that produce the antibiotic 2,4-diacetylphoroglucinol (2,4-DAPG) are among the most effective rhizobacteria controlling diseases caused by soilborne pathogens. The genotypic diversity that exists among 2,4-DAPG producers can be exploited to improve rhizosphere competence and biocontrol activity. Knowing that D-genotype 2,4-DAPG-producing strains ...
OBJECTIVES In thrombocytopenia, high accuracy and precision of low platelet count is essential for appropriate decisions. The recently introduced Sysmex XN2000 analyzer (Sysmex, Kobe, Japan) offers 3 methods for platelet counting: impedance (PLT-I), optical (PLT-O), and a new fluorescence method (PLT-F). The precision of the PLT-F method in blood samples with platelet counts less than 50 × 10(3...
Platelets (Plt) accumulate in reperfused myocardium but their effect on myocardial necrosis has not been established. We tested the hypothesis that the effect of Plt depends on their activation status. Pig Plt were obtained before 48 min of coronary occlusion (pre-CO-Plt), 10 min after reperfusion (R-Plt), or after a 60-min sham operation (sham-Plt). Plt were infused into isolated rat hearts (n...
