584. A 67-year-old man complaining of headache, fever, and general weakness was admitted to the hospital. On physical examination, a physician revealed scanty rash on lateral surfaces of the body, enlarged spleen. At the age of 35 the patient was attacked by typhus. Findings of serological investigation: reaction of agglutination with Rickettsia Prowazekii was positive (titer 1:160), reaction of agglutination with Proteus OH19 was negative. What disease was the patient diagnosed with?
А. Brill-Zinsser disease.
В. Murine typhus (flea-born typhus).
С. Paroxysmal rickettsiosis.
D. Rickettsial pox.
Е. Lyme disease.
585. A patient suspected of rickettsiosis was admitted to the hospital. What method of diagnostics should be used to confirm the diagnosis?
А. Serological.
В. Microscopic.
С. Cultivation of the causative agent on artificial nutrient medium.
D. Cultivation of the causative agent in chicken embryo.
Е. Biological.
586. An old man diagnosed with epidemic typhus was admitted to the hospital. The patient remembered that at the age of 20 he had already contracted the disease. A doctor administered reaction of agglutination with R. prowazekii. Immunoglobulins of what class will confirm the disease of Brill-Zinsser?
А. IgG.
В. IgА.
С. IgМ.
D. Ig Е.
Е. IgD.
587. Which of the following methods is frequently used to diagnose epidemic typhus?
А. Serological method.
В. Virological (infecting cultural cells).
С. Virological (infecting chicken embryo).
D. Bacteriological method.
Е. Skin-allergic test.
588. An elderly man without definite place of living presented to the hospital with the following symptoms: fever, dizziness, and skin rash. Since the patient was identified with pediculosis, a doctor suspected typhus. What method was likely to confirm the diagnosis?
А. Serological.
В. Bacteriological.
С. Virological.
D. Microscopic.
Е. Skin-allergic test.
589. After natural disaster (earthquake with large destroyed area), there was registered an episode of the disease, the causative agent of which seemed to be transmitted by lice. What is the causative agent of the disease?
А. Rickettsia prowazekii.
В. Rickettsia typhi.
С. Rickettsia rickettsii.
D. Rickettsia conorii.
Е. Rickettsia akari.
590. A man who had previously suffered from typhus, contracted the same type of the disease on the background of full epidemiological welfare. He was diagnosed with recurrent typhoid fever − Brill-Zinsser disease. Name the transmitter of the disease.
А. The disease is not transmissible.
В. Ticks.
С. Lice.
D. Mosquitos.
Е. Flies.
591. A patient of 55 years old was presented to the hospital complaining of rash on the body, dizziness, and fever. He was initially diagnosed with typhus. There were no recorded cases of the same disease in the region. A doctor found out that the patient had contracted typhus while studying at school. What is the preliminary diagnosis of the disease?
А. Brill-Zinsser disease.
В. Typhoid fever.
С. Measles.
D. Rubella.
Е. Cholera.
592. An infected patient identified with roseolous rash was admitted to the hospital. The patient was initially diagnosed with typhus. How can the diagnosis be confirmed?
А. By the reaction of agglutination with typhus diagnosticum.
В. By bacteriological method.
С. By biological test.
D. By skin allergic test.
Е
. By
microscopy of rash, Gram staining.
