 Two independent F2 populations of Lycopersicon esculentum×L. pennellii which have previously been investigated in RFLP mapping studies were used for construction of a highly saturated integrated AFLP map. This map spanned 1482 cM and contained 67 RFLP markers, 1078 AFLP markers obtained with 22 EcoRI+MseI primer combinations and 97 AFLP markers obtained(More)
This paper describes the distribution of highly polymorphic GATA- and GACA-containing DNA regions in tomato. To study the distribution of these polymorphic regions, a mapping experiment was done. The segregation of 32 GATA- and GACA-containing loci was analyzed in a F2 population from a cross between Lycopersicon esculentum and L. pennellii. From these(More)
PCR-based DNA fingerprinting was used to characterize 48 clinical isolates of Yersinia enterocolitica. The samples were examined by random amplified polymorphic DNA (RAPD-PCR) and inter-repeat PCR (IR-PCR). IR-PCR with two enterobacterial repetitive intergenic consensus primers resulted in patterns which were poorly discriminated; 2 of 11 arbitrary primers(More)
Objectives: Detection of Yersinia enterocolitica in clinical samples is still not sensitive and fast enough. Polymerase chain reaction (PCR) offers the advantages of sensitivity, specificity, and rapidity. A two-step PCR assay to detect pathogenic Y: enterocolitica in infected tissue has been developed. Method: In the first step of the PCR assay, a general(More)
The immune-response against infection with Yersinia enterocolitica was studied in a rat model which resembles yersiniosis in humans. Lewis, Fischer and Brown Norway rats were inoculated with Y. enterocolitica and the cytokine mRNA expression in spleen and Peyer's patches was determined. In Brown Norway rats the infection was mild and Yersinia enterocolitica(More)
AIM The sensitive detection of pathogenic Yersinia enterocolitica in paraffin embedded tissue sections by in situ hybridisation (ISH). METHODS Y enterocolitica infected cell lines, rat spleens, and patient biopsy specimens were used to compare conventional ISH, immune fluorescence assay (IFA) detection, and catalysed reporter deposition (CARD) signal(More)
