Which of the following is classified as a viral disease?

Salmonella
Leukosis
Coccidiosis
Mycoplasmosis

The correct answer is: Leukosis

Leukosis is classified as a viral disease because it is caused by avian leukosis viruses, which are part of the Retroviridae family. These viruses can lead to tumors in birds, particularly affecting chickens and causing a variety of health issues, including immunosuppression and increased susceptibility to other infections. In contrast, Salmonella is a bacterial infection that causes enteritis in poultry. Coccidiosis is a parasitic disease caused by coccidia, which are protozoan parasites. Mycoplasmosis, on the other hand, is caused by mycoplasma bacteria, leading to respiratory issues among other symptoms in poultry. Thus, leukosis is distinctly recognized as a viral disease due to its specific etiological agents.
