Poultry Judging Practice Test

Which of the following diseases is classified as viral?

1. Leukosis

2. Coccidiosis

3. Salmonellosis

4. Newcastle disease

The correct answer is: Leukosis

Newcastle disease is classified as a viral disease affecting poultry. This disease is caused by the Newcastle disease virus (NDV), which belongs to the Paramyxoviridae family. It can cause severe respiratory illnesses and has the potential to lead to significant mortality rates in affected bird populations. Symptoms can vary widely and include nasal discharge, coughing, and neurological signs, depending on the virulence of the strain involved. Effective biosecurity measures and vaccinations are key components in managing and controlling the spread of Newcastle disease in poultry farms. In contrast, the other diseases listed are caused by different types of pathogens. Leukosis is classified as a viral disease, but Newcastle disease is specifically notable in poultry practices. Coccidiosis is a parasitic disease resulting from infection with protozoan parasites, while Salmonellosis is a bacterial infection caused by Salmonella species. Understanding the distinctions between these categories is crucial for proper disease management and prevention in poultry production.
