The cytolethal distending toxin of Haemophilus ducreyi (HdCDT) is a three-component toxin that induces the arrest of the mammalian cell cycle in the G2 phase. All of the individual gene products, CdtA, CdtB and CdtC, are required for toxic activity on cultured mammalian cells. The CdtB component alone exerts nuclease activity. The individual HdCDT(More)
BACKGROUND The 26 kDa protein, which is an alkyl hydroperoxide reductase (AhpC) homologue, has earlier been described as specific for Helicobacter pylori. The aims of this study were to analyse whether this protein, or the corresponding gene, could be identified in other Helicobacter species. MATERIALS AND METHODS Two different monoclonal antibodies(More)
Due to earlier contradictory results regarding the localization of the putative Helicobacter pylori adhesin A (HpaA), we aimed to compare the gene and protein expression and surface localization of HpaA in different H. pylori strains. Five H. pylori strains were cultivated for 11 days and analysed by Northern blot analysis, flow cytometry (FCM),(More)
A method for testing the effect of disinfectants against Mycobacterium tuberculosis was developed using glass slide carriers contaminated with Myco. tuberculosis from spleens of guinea-pigs. The method was found to be useful although a greater number of colony forming units, permitting calculation of a reduction factor in the range of 10(5), is desirable.(More)
