Implication
Consistent serological profiles limit differentiation of typhus episodes; leaves open whether advanced assays outperform classical tests.

P
Population
Patients suffering from primary and recrudescent typhus infections, and donor blood sera
I
Intervention
Microimmunofluorescence and Western immunoblotting
C
Comparator
Classical complement fixation reaction and the Weil-Felix test
O
Outcome
Serological responses to Rickettsia prowazekii and both Proteus vulgaris OX19 and OX2surrogate
Microimmunofluorescence and Western immunoblotting reveal that serological responses to R. prowazekii are similar in primary and recrudescent typhus, predominantly involving IgG and IgM against the 100-kDa protein and lipopolysaccharide.
