A patient with hepatitis B has been examined for detecting the possible concomitant agent, which complicates the basic disease. What agent is it?

Serological tests are used for checking of the

Hepatitis B virus antigens presence in donors' blood.

Which test should be used?

+Solid-phase enzyme immunoassay

Immunoelectrophoresis

Indirect hemagglutination test

Complement fixation test

Indirect immunofluorescence test

Hepatitis D virus (delta-agent) is a defective

Agent. It can replicate only in cells already infected with

One of the viruses. With which one?

+Hepatitis B

Human immunodeficiency virus

Hepatitis A

Hepatitis E

Epstein-Barr virus

There is registeration of the outbreak of hepatitis

Associated with water factor.

What could virus induce this outbreak?

+Hepatitis A

Hepatitis G

Hepatitis C

Hepatitis D

Hepatitis B

During an operative intervention a patient had blood

Transfusion. In his blood the presence of the following causative

agent should be checked:

+Hepatitis B virus

Hepatitis A virus

Hepatitis E virus

Enteroviruses

Adenoviruses

HBs-antigen has been revealed during enzyme immunoassay in

Serum. What infection can be diagnosed

By this antigen detecting?

+Virus hepatitis B

Syphilis

Virus hepatitis A

AIDS

Tuberculosis

Wich one of the following is the MOST reasonable explanation for

The ability of hepatitis B virus to cause chronic infection?

Viral DNA may persist within the host cell

Many humans are immunologically tolerant to HBs antigen

The liver is an “immunologically sheltered” site

Infection does not elicit the production of antibody

Each of the following pathogens is likely to establish chronic

or latent infection EXCEPT:

+hepatitis A virus

hepatitis B virus

hepatitis C virus

hepatitis D virus

What is vaccine used for prophylaxis of hepatitis B?

+Recombinant vaccine

Live vaccine

Killed vaccine

Chemical vaccine

Hepatocellular carcinoma is developed after hepatitis B.

What is type of infection viral genome interaction with human

Cell genome causing cancer?

+Integrative

Latent

Abortive

Acute

Chronical

What is the most resistant to chemical and physical

Factors influence virus?

+В-hepatitis

Measles

Polio

Flu

Epidemic mumps

Stomatologist want to be vaccinated against

B-hepatitis. What preparation will be used for vaccination?

+Recombinant vaccine

Killed vaccine

Live vaccine

Toxoid

Chemical vaccine

Patient after car accident was brought to the hospital. It’s

Necessary to carry out him blood transfusion. With what reaction

Donor’s blood can be checked for hepatitis B antigen presence?

+Enzyme linked immunoassay (ELISA)

Hemagglutination inhibition test

Hemadsorption inhibition test

Complement fixation test.

The following laboratory results were received from

patient: HBsAg–, HBeAg–, anti-HBsG+,

anti-HBsM–, HCAg+. What diagnosis is confirmed by this data?

+ hepatitis С, hepatitis B in anamnesis

hepatitis С

Chronic hepatitis B with low replication activity

hepatitis B relapse

Repeated contamination with hepatitis B

A patient with hepatitis B has been examined for detecting the possible concomitant agent, which complicates the basic disease. What agent is it?

+Delta-virus

Hepatitis C virus

Hepatitis G virus

Hepatitis E virus

HBs-antigen
