Typing African Relapsing Fever Spirochetes
Relapsing fever Borrelia spp. challenge microbiologic typing because they possess segmented genomes that maintain essential genes on large linear plasmids. Antigenic variation further complicates typing. Intergenic spacer (IGS, between 16S-23S genes) heterogeneity provides resolution among Lyme disease-associated and some relapsing fever spirochetes. We used an IGS fragment for typing East Afri...
متن کاملThere Is a Method to the Madness: Strategies to Study Host Complement Evasion by Lyme Disease and Relapsing Fever Spirochetes
Lyme disease and relapsing fever are caused by various Borrelia species. Lyme disease borreliae, the most common vector-borne pathogens in both the U.S. and Europe, are transmitted by Ixodes ticks and disseminate from the site of tick bites to tissues leading to erythema migrans skin rash, arthritis, carditis, and neuroborreliosis. Relapsing fever borreliae, carried by ticks and lice, trigger r...
متن کاملImmune evasion of the Lyme disease spirochetes.
The Lyme disease spirochetes, Borrelia burgdorferi sensu lato, have adapted very well to both surviving and persisting in the mammalian host despite a strong host antibody response. It appears that both temporal and spatial regulation of outer surface proteins have contributed to this persistence. The spirochetes are able to bind fH and FHL-1 to their surface, resulting in decreased complement ...
متن کاملTick-Borne Relapsing Fever Spirochetes in the Americas
Relapsing fever spirochetes are tick- and louse-borne pathogens that primarily afflict those in impoverished countries. Historically the pathogens have had a significant impact on public health, yet currently they are often overlooked because of the nonspecific display of disease. In this review, we discuss aspects of relapsing fever (RF) spirochete pathogenesis including the: (1) clinical mani...
متن کاملLymphoma: Immune Evasion Strategies
While the cellular origin of lymphoma is often characterized by chromosomal translocations and other genetic aberrations, its growth and development into a malignant neoplasm is highly dependent upon its ability to escape natural host defenses. Neoplastic cells interact with a variety of non-malignant cells in the tumor milieu to create an immunosuppressive microenvironment. The resulting funct...
