Lesson 7: Strategies for Managing Plant Viral Diseases
Managing plant viral diseases requires an integrated approach combining cultural practices, biological controls, genetic resistance, and sometimes chemical interventions to reduce the virus spread, impact, and establishment in crops. 1.…
Lesson 9: Viruses of the Integumentary (Skin) System
Viruses affecting the integumentary system (the skin and its associated structures such as hair, nails, and glands) can cause a variety of diseases. These viruses often present with rashes, lesions,…
Lesson 8: Diagnosing Plant Viral Infections
Diagnosing plant viral infections is a crucial step in managing plant health and preventing the spread of viruses within crops. Plant virus diagnosis involves observing symptoms, using specialized diagnostic tools,…
Lesson 10: Viruses of the Nervous System

Lesson 11: The Multisystem Viruses
Multisystem viruses are those that can affect multiple organ systems within a host, often leading to widespread (generalized infections) and severe disease. These viruses can cause systemic infections, and their…
Why is it difficult to control African Swine fever in Tanzania?
Introduction African swine fever virus (ASFV) is a double stranded DNA virus of the family Asfaviridae and genus Asfivirus that causes African swine fever (ASF). The disease can lead up…
How are the RBCs used for HA and HI prepared?
Hemagglutination assay and hemagglutination inhibition test (covered in the diagnostic virology) are very important assay Virology. Both use red blood cells where some viruses tend to bind on the sialic…
Interactions of hemagglutinins with sialic acids receptors
What’s a hemagglutinin? Orthomyxoviruses include envelope-associated proteins, hemagglutinin (HA) and neuraminidase (NA) inserted into the lipid bilayer and protruding on the floor as spikes. The hemagglutinin glycoprotein (HA) performs vital…
