Abstract
Tissue damage instead of host protection is sometimes the outcome of the interaction between antibody and microbial antigen. Poststreptococcal rheumatic fever and glomerulonephritis are consequences of immune response to an infectious agent. Common fungi are associated with allergic lung syndromes. Allergic manifestations often accompany helminthic infections. “Slow virus” infections may cause certain neurologic disorders. Treatment of immunologic events complicating infectious diseases should be directed toward prevention rather than cure of the immunologic injury
