Plant pathogenic fungi differentiate a highly specialized infection cell called an appressorium to infect their hosts. Appressorium formation is induced by specific physical or chemical cues provided by the host plant. Several components of signal transduction pathways have been identified that are involved in infection-related morphogenesis and virulence(More)
The costs of a hospital-wide selective screening programme were analysed for a period of 19 months. During this time, 539 inpatients were screened, of whom 111 were MRSA-positive. Based on microbiological costs (staff and materials) and the costs of preventive contact isolation for 2 days until microbiological results were available (including material(More)
To study the molecular basis of biotrophic nutrient uptake by plant parasitic rust fungi, the gene (Uf-PMA1) encoding the plasma membrane H(+)-ATPase from Uromyces fabae was isolated. Uf-PMA1 exists probably as a single gene. However, two nearly identical sequences were identified; the similarity apparently is due to two Uf-PMA1 alleles in the dikaryotic(More)
Screening of potential MRSA-positive patients at hospital admission is recommended in German and international guidelines. This policy has been shown to be effective in reducing the frequency of nosocomial MRSA transmissions in the event of an outbreak, but the influence of screening on reducing hospital-acquired MRSA infections in a hospital setting where(More)
Ribonuclease T1 was crystallized under various conditions. Form I crystals were produced by microdialysis against 53% (v/v) 2-methyl-2,4-pentanediol in 0.01 M sodium acetate, 0.05% 2'-guanylic acid (2'GMP) and 0.02% NaN3 (pH 6.2-7.2). These crystals are tetragonal, space group P41212 and contain two molecules per asymmetric unit; cell dimensions are a = b =(More)
