Answer to Question #124294 in Microbiology for Ibrahim jibrin

Question

write a concise note on immunity in parasitic infections

Answer 1

Most parasitic infections are chronic because of weak innate immunity and the ability of parasites to evade or resist elimination by adaptive immune responses.

Most of Parasites evade the immune system by varying their antigens during residence in vertebrate hosts, by acquiring resistance to immune effector mechanisms, and by masking and shedding their surface antigens.
