BLS 113: Virology

Group assignment: April 2022

Instructions: The assignment must be submitted before 29th April 2022 and there will be a presentation in the class (date to be determined)

 

QUESTION

  1. Describe extensively the family located in your group of choice based on the following guidelines:
  • Family name
  • History of the discovery of the family
  • Describe the general and specific features of viruses in families

-structure (electron microscopic figures and a well-labeled diagram)

-virion size (nm)

-type and nature of nucleic acid (RND or DNA, strandedness, sense, segments, linear or circular)

-genome size (kb)

-The type of capsid symmetry

-Nature of outer covering (enveloped or naked)

-Baltimore classification

-name if any, enzyme(s) packaged in the virion

 

  1. Describe the mode of replication of the viruses under the family

-draw a well-labeled diagram that illustrates the replication cycle

-where do the replication and transcription of the virus genome take place

-name all the enzymes involved during the replication cycle and state whether each is provided by the host cell or virus (use a tabular form)

 

  1. What effects do the viruses cause on the host cell in the given family
  • cytocidal or cell fusion or formation of inclusion bodies or transformation of cells (can be more than one)

 

  1. List all the genera of veterinary and medical importance under the family and their respective diseases in a tabular form
Genus Virus species Disease Affect humans or animals (specify)
Human
Cattle

 

  1. Describe the mode of action of the antivirals used to control disease(s) of veterinary and or medical importance under the family (if available). Use a table if you have more than one antiviral
Antiviral Mode of action Target disease/virus

BLS 108: Assignment 2014

Instructions:   The work should not exceed 15 pages in word office which will be submitted as a soft copy later on. There will be marked presentations for the assignment before the end of the course (5 minutes per student), and the PowerPoint will be submitted as a soft copy after the presentations.

Describe extensively the family located to your name based on the following guidelines:

  1. Basic history of the family (how and when was discovered, who discovered it)
  2. The general structure of the viruses under the family (structure, size, the symmetry, naked or enveloped)
  3. The type (s) of the genomes from different viruses under the family (type of nucleic acid-ds, ss, DNA or RNA, circular or linear, and the replication site-cytoplasm or nucleus)
  4. The nomenclature and classification of viruses under the family (basis for naming viruses if any, group the viruses in tabular form based on genus, species, diseases, and the host they affect)
  5. The mode of replication of the viruses under the family (diagram is essential)
  6. List the different methods that are used to study and identify viruses under the family
  7. What effects do the viruses cause on the host cell in the given family
  8. Briefly, describe one important disease in the family under the following subheadings: pathogenesis, clinical signs, prevention, and control.
