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? +Â-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 Ń, hepatitis B in anamnesis hepatitis Ń 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 Date: 2016-03-03; view: 827
