The Weil-Felix (rickettsial infections) and related infections (such as anaplasmosis, ehrlichiosis, and Q fever) are caused by an unusual type of bacteria that can live only inside the cells of another organism.
It is recommended in:Rickettsia is a bacteria transmitted by ticks, fleas, and lice that is the root of diseases in human beings.Rickettsia disease comprises a set of diseases caused by microorganisms like typhus, rickettsia pox, Boutonneuse fever, African tick bite fever, Rocky Mountain spotted fever, and Australian Tick Typhus,Symptoms include fever, severe headache, a characteristic rash, and the general feeling of illness (malaise).As the infection progresses, people typically experience confusion and severe weakness, often with a cough, difficulty breathing, and sometimes vomiting.
The Weil-Felix (rickettsial infections) test: It is a nonspecific agglutination test that utilises antigenic cross-reactivity between a rickettsia and certain non-motile Proteus serotypes for the detection of anti-rickettsia antibodies (so-called Weil-Felix antibodies) in a patient's serum.The Weil-Felix test is based on cross-reactions that occur between antibodies produced in acute rickettsial infections with antigens of OX (OX 19, OX 2, and OXK) strains of Proteus species.The rickettsia species include two antigenically defined groups that are closely related genetically but differ in their surface-exposed protein and lipopolysaccharide antigens.
The Weil-Felix (rickettsial infections) test is prescribed by your doctor after completing the assessment of your conditions.
