Unstable antigenic variation of leptospiras
Zentralblatt für Bakteriologie, Mikrobiologie und Hygiene. 1. Abt. Originale. A, Medizinische Mikrobiologie, Infektionskrankheiten und Parasitologie, 1981The antigenic variants which were found in leptospiras, Leptospira interrogans serovar copenhageni Shibaura grown in a liquid medium containing a homologous antiserum were found to be unstable. The unstable variants showed decreased agglutinability against the homologous antiserum.

Antigenic Variation in Malaria
1977Like most protozoan infections malaria is usually chronic. Even in the absence of persistent exoerythrocytic infection parasites may remain in the blood for months after antiplasmodial antibody is detectable in the serum.

Antigenic Variation in Plasmodium falciparum
2015Plasmodium falciparum is the protozoan parasite that causes most malaria-associated morbidity and mortality in humans with over 500,000 deaths annually. The disease symptoms are associated with repeated cycles of invasion and asexual multiplication inside red blood cells of the parasite. Partial, non-sterile immunity to P.

Antigenic variation in malaria parasites
Immunology Today, 1985Antigenic variation and sequestration in organ capillary systems are two of the ways by which malaria parasites escape immune effector mechanisms. Here Marcel Hommel discusses the presence of variant antigens and endothelial-binding molecules on the surface of infected erythrocytes in the context of malaria immunity.

Molecular genetics of antigenic variation
Immunology Today, 1991Antigenic variation is one of the most effective strategies developed by parasites to escape immune destruction. It requires a large wardrobe of surface coats and mechanisms to exchange one coat for an unrelated one. The molecular principles of antigenic variation are now largely known in the bacterial species Borrelia and Neisseria and in the protozoa

Antigenic variation in African trypanosomes
1999Although several hundred of different antigen genes exist in the trypanosome genome, only one is usually expressed at a time. This expression occurs in one of several possible telomeric expression sites. Besides being exclusively telomeric, transcription of the antigen gene exhibits other particular characteristics: the RNA polymerase is highly ...
