Serological Reactivity of Sera from Scrub Typhus Patients against Weil‐Felix Test Antigens [PDF]

Microbiology and Immunology, 1993
AbstractSera from 17 patients of scrub typhus in the acute and convalescent phases were tested by indirect immunoperoxidase test, Weil‐Felix (WF) test, enzyme‐linked immunosorbent assay (ELISA), and immunoblotting. In the comparison of antibody titers between acute‐ and convalescent‐phase sera, we recognized a parallelism of increment between the ...

Serological Studies of the Antigenic Similarity between Typhus Group Rickettsiae and Weil‐Felix Test Antigens [PDF]

Microbiology and Immunology, 1995
AbstractThe sera from two patients with murine typhus reacted with whole cells of Rickettsia prowazekii, R. typhi, and Proteus vulgaris OX19, and with lipopolysaccharides (LPS) from the spotted fever group rickettsia strain TT‐118 and P. vulgaris OX19 in the enzyme‐linked immunosorbent assay.
