NOTE

DISEASE CAUSING AGENTS AND THEIR MODE OF TRANSMISSION

  1. BACTERIA:

 Mode of Transmission:

  1. Direct Contact: Bacteria can spread through direct contact with infected animals, contaminated surfaces, or bodily fluids.
  2. Indirect Contact: Transmission can occur through fomites (inanimate objects) such as equipment, feed, or water contaminated with bacterial pathogens..
  3. Ingestion: Animals can become infected by ingesting food or water contaminated with pathogenic bacteria.
  4. Vector-Borne Transmission: Certain bacteria can be transmitted to animals through the bite of arthropod vectors such as ticks, fleas, or mosquitoes.

       2. VIRUS:

Mode of Transmission:

  1. Direct Contact: Viruses can spread through direct contact with infected animals, including saliva, nasal discharge, feces, or blood.
  2. Indirect Contact: Transmission can occur through contaminated surfaces, equipment, or fomites.
  3. Vector-Borne Transmission: Some viruses are transmitted to animals through the bite of arthropod vectors such as mosquitoes, ticks, or flies.
  4. Vertical Transmission: Viruses can be transmitted from mother to offspring during gestation, birth, or through the ingestion of infected milk.

       3. FUNGI:

Mode of Transmission:

  1. Direct Contact: Fungal pathogens can spread through direct contact with infected animals, particularly through skin-to-skin contact or contact with contaminated materials.
  2. Indirect Contact: Transmission can occur through contaminated equipment, bedding, or environmental surfaces.
  3. Inhalation: Fungal spores can be inhaled by animals, leading to respiratory infections.
  4. Ingestion: Some fungal pathogens can infect animals through the ingestion of contaminated feed or water.
  5. Vector-Borne Transmission: Certain fungal diseases can be transmitted by arthropod vectors such as ticks or flies.

       4. PROTOZOA:

Mode of Transmission:

  1. Direct Contact: Protozoal parasites can spread through direct contact with infected animals or contaminated bodily fluids such as feces.
  2. Indirect Contact: Transmission can occur through contaminated water sources, feed, or environmental surfaces.
  3. Ingestion: Animals can become infected by ingesting food or water contaminated with protozoal cysts or oocysts.
  4. Vector-Borne Transmission: Some protozoal parasites are transmitted to animals through the bite of arthropod vectors such as mosquitoes or ticks.
  5. Vertical Transmission: Protozoal parasites can be transmitted from mother to offspring during gestation or through the ingestion of infected milk.

EVALUATION: 1. Identify 4 mode of transmission of bacteria

  1. Identify 4 mode of transmission of virus
  2. Identify 3 mode of transmission of fungi
  3. Identify 3 mode of transmission of protozoa

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
