With that knowledge, they hope to find new ways to repel or kill the insects, whose bite transmits sleeping sickness, a parasitic disease that, like rabies, drives its victims … Continue reading New Tool To FIght Deadly Tetse Fly

Mechanisms Of Antigenic Variation In Borrelia Hermsii And African Trypanosomes

INTRODUCTION Several pathogenic microorganisms, ranging from viruses to protozoa, evade the mammalian immune response by periodically changing the molecular constituents on their surface, a phenomenon called antigenic variation(1). Two pathogens particularly adept at using this strategy are Borrelia hermsii, a prokaryotic spirochete that causes relapsing fever in the western United States and Canada(2), and African … Continue reading Mechanisms Of Antigenic Variation In Borrelia Hermsii And African Trypanosomes
