Pathogens Of Farm Animal Diseases
Muhtasari
Every disease a farm animal ever catches, from a cow going down with anthrax to a whole poultry flock wiped out by Newcastle disease, begins with the same event: a living organism too small to see invades the animal's body. WAEC calls that organism a pathogen, and sorts every pathogen a candidate is expected to know into just four families. Learn the four, learn how each one attacks, and every disease topic that follows in this section becomes a matter of recognising which family is at work.
In this lesson you will learn what a pathogen is, meet bacteria, viruses, fungi and protozoa in turn with the diseases each is best known for on a Nigerian farm, and understand, in plain terms, how each type of organism actually makes an animal sick. That mechanism, not just the name of the disease, is what lets you reason about a farm scenario you have never met before.
