SCOPE OF THE PROBLEM Among U.S. women, breast cancer is the most commonly diagnosed cancer and remains second only to lung cancer as a cause of cancer-related mortality. The American Cancer Society (ACS) estimates that 182,800 new cases of female breast cancer and 41,200 deaths from breast cancer will occur in 2000. Since the 1950s, the incidence of(More)
Genomic studies on pathogenic and environmental mycobacteria are of growing interest for understanding of their evolution, distribution, adaptation, and host-pathogen interaction. Since most mycobacteria are slow growers, material from in vitro cultures is usually scarce. The robust mycobacterial cell wall hinders both experimental cell lysis and efficient(More)
This paper presents sequence and population genetic data of the microsatellite marker DXS6809 (GDB 365492) obtained from a German population sample ( n=725 chromosomes). DXS6809 is a highly polymorphic X-linked tetranucleotide polymorphism presenting 12 alleles in our population. Sequencing of 77 PCR products covering 12 alleles (by length), characterised(More)
Mycobacterium ulcerans is the causative agent of Buruli ulcer, the third most common mycobacterial disease after tuberculosis and leprosy. It is an emerging infectious disease that afflicts mainly children and youths in West Africa. Little is known about the evolution and transmission mode of M. ulcerans, partially due to the lack of known genetic(More)
BACKGROUND Comparative genomics has greatly improved our understanding of the evolution of pathogenic mycobacteria such as Mycobacterium tuberculosis. Here we have used data from a genome microarray analysis to explore insertion-deletion (InDel) polymorphism among a diverse strain collection of Mycobacterium ulcerans, the causative agent of the devastating(More)
Buruli ulcer (BU) is an emerging necrotizing disease of the skin and subcutaneous tissue caused by Mycobacterium ulcerans. While proximity to stagnant or slow flowing water bodies is a risk factor for acquiring BU, the epidemiology and mode of M. ulcerans transmission is poorly understood. Here we have used high-throughput DNA sequencing and comparisons of(More)
Elucidation of the transmission, epidemiology, and evolution of Mycobacterium ulcerans, the causative agent of Buruli ulcer, is hampered by the striking lack of genetic diversity of this emerging pathogen. However, by using a prototype plasmid-based microarray that covered 10% of the genome, we found multiple genomic DNA deletions among 30 M. ulcerans(More)
BACKGROUND Buruli ulcer (BU) is a skin disease caused by Mycobacterium ulcerans. Its exact mode of transmission is not known. Previous studies have identified demographic, socio-economic, health and hygiene as well as environment related risk factors. We investigated whether the same factors pertain in Suhum-Kraboa-Coaltar (SKC) and Akuapem South (AS)(More)
The highly immunogenic mycobacterial proteins ESAT-6, CFP-10, and HspX represent potential target antigens for the development of subunit vaccines and immunodiagnostic tests. Recently, the complete genome sequence revealed the absence of these coding sequences in Mycobacterium ulcerans, the causative agent of the emerging human disease Buruli ulcer. Genome(More)
Mycolactone is an immunosuppressive cytotoxin responsible for the clinical manifestation of Buruli ulcer in humans. It was believed to be confined to its etiologic agent, Mycobacterium ulcerans. However, the identification of other mycolactone-producing mycobacteria (MPMs) in other species, including Mycobacterium marinum, indicated a more complex taxonomic(More)
