The most recently identified human herpesvirus, Kaposi's sarcoma (KS)-associated herpesvirus (KSHV) or human her-pesvirus 8 (HHV-8), has been found to be a necessary, although perhaps not sufficient, etiologic agent for all forms of KS (1, 2). This virus is also invariably present in a rare subset of malignant lymphomas, primary effusion lympho-mas (PELs), and in a significant percentage of pat...
For more than two decades, scientists have used Agrobacterium-mediated genetic transformation to generate transgenic plants. Initial technologies to introduce genes of interest (goi) into Agrobacterium involved complex microbial genetic methodologies that inserted these goi into the transfer DNA (T-DNA) region of large tumor-inducing plasmids (Ti-plasmids). However, scientists eventually learne...
Thisted Lambertz, S. 2005. Development of a PCR-based method for detection of pathogenic Yersinia enterocolitica in pork. Doctor ́s dissertation. ISSN 1652-6880, ISBN 91-576-6922-8 During the last decade, Yersinia enterocolitica has been reported to cause between 500 and 800 cases of human gastroenteritis per year in Sweden. As pigs are the only animals in human food production that regularly ha...

The global transcriptional regulator H-NS selectively silences bacterial genes associated with pathogenicity and responses to environmental 20 insults. Although there is ample evidence that H-NS binds preferentially to DNA containing curved regions, we show here that a major basis for this selectivity is the presence of a conserved sequence motif in H-NS target transcriptons. We further show 25...
Members of the genus Agrobacterium cause the neoplastic diseases crown gall, hairy root, and cane gall on numerous plant species. Extensive genetic analyses conducted in the 1980s identified key bacterial genes involved in virulence. During the past decade, however, genomic technologies have revealed numerous additional bacterial genes that more subtly influence transformation. The results of t...
IN MYELOMA, THE ROLE of the bone marrow microenvironment has been shown to be of increasing importance in supporting the malignant plasma cell.1,2 Specifically, nonmalignant stromal cells in the bone marrow from myeloma patients have been shown to promote the growth and prevent the apoptosis of malignant plasma cells largely by the production of interleukin-6 (IL-6).1-3 Recently, a new member o...
