Non-infectious - cancer, diabetes, scurvy, allergies.
Infectious - asthma, asbestosis, chickenpox, herpes.
Non-infectious - ebola, cystic fibrosis, bronchitis, kuru.
Pathogens are organisms that can produce disease or illness in another organism. Select the list that names types of pathogens only.
Prions, bacteria, protozoa, fungi.
Parasites, viruses, cancer, prokaryotes
Macroparasites, prions, protozoa, pertussia
Viroids, obesity, comycete, clones.
Persistent infection by a virus is best described as:
The protein synthesis mechanisms of an infected host cell producing many new virions.
Virions dormant inside an infected call until they break out and trigger symptoms of disease.
The release of new virions from the infected host cell to infect surrounding cells.
The infected host cell producing viral DNA from the virus RNA.
A non-cellular pathogen that consists of protein particles and can replicate itself inside infected cells without DNA or RNA is called a:
Virus
Virion
Viroid
Prion
Koch's postulates provide a scientific method of:
Finding out how fast bacteria reproduce
Identifying the causative organism of infectious diseases
Identifying the causative organism of infectious diseases
Preventing the spread of diseases
Antibiotics:
are produced by B lymphocytes
trigger the immune response
combat bacterial infections
kill mainly viruses and bacteria
Which of the following diseases has been eliminated by a global vaccination program?
Smallpox
Polio
Measles
Diptheria
Media reports sometimes refer to large scale diseases as epidemics or pandemics. Identify the correct distinction between the two terms.
The bubonic plague bacterium caused epidemics and pandemics throughout earlier, less hygienic times.
Pandemic is a rapid and unusual spread of an infectious disease; epidemic is a pandemic that has become more global.
Epidemic is a rapid and unusual spread of an infectious disease; pandemic is an epidemic that has become more global.
Human movements around the globe tend to cause epidemics and pandemics, such as the SARS outbreak.
Which one of the following statements is correct?
Antibodies are chemicals produced by B lymphocytes
Antibodies are chemicals produced by T lymphocytes
Antigens initiate the second line of defence
Antibodies, antibiotics and antigens are different words with similar meaning.
The innate immune system has responses that include:
cilia, macrophages and B cells
phagocytosis, inflammation response and macrophages.
macrophages, T cells and B cells.
Inflammation response, immune response, antigens.
Identify the statement that is not true for antibodies:
They are large protein molecules called immunoglobulins.
They have two identical arms that bind to specific antigens.
They have an arm that interacts with other immune response cells, like mast cells.
They are produced by neutrophils.
Which of the following is not true for complement proteins?
Complement proteins are part of the innate immune response.
Complement proteins attract phagocytes to the site of the infection.
Complement proteins include antibodies.
Complement proteins can be activated in the presence of antibody-antigen reactions.
Natural active immunity is achieved because of:
Exposure to live or attenuated vaccines.
Infection by particular bacteria or virus.
The administration of antibodies or antitoxin specific to a particular microorganism.
Adequate increase feeding in newborn infants.
Innate immune responses are critical to maintaining the health of an individual because:
They are specific to the antigens on pathogenic organisms.
The innate response produces antigens, which bind antibodies to mast cells.
They provide immediate and continuous protection against foreign antibodies.
All of the above.
Antiviral medications provide treatments to reduce the seriousness of viral infections. Which of the following best describes how they do this?
They block the receptors used by the virus to attach to and enter the cells.
They block transcription in the infected cells.
They prevent the virus particles from leaving the cell.
all of the above.
Different drugs are appropriate for different pathogens. Canestan fights fungi, penicillin fights bacteria, Relenza is effective against influenza virus. The plasmodium that causes malaria is a protozoan. Select the most effective treatment for malaria.
Canestan
Penicillin
Relenza
None of the above
Which of the following involves gene delivery by nasal sprays as a treatment strategy?
Removal of the genetic material from the adenovirus.
Using bacteria as vectors for the required gene
Aerosolisation of plasmid DNA
all of the above
Rational design of a drug to combat a virus involves targeting a particular viral protein, Select the characteristics that would be most useful in designing a drug to combat the virus.
The protein is used by the virus in the early stages of reproduction.
The protein is used by the virus to attach to its host cells.
The protein is used by the virus in the later stages of its reproduction.
The protein is common to several strains of the virus.
