Introduction to Animals Diseases

Have you ever thought that there are some similarities between humans and animals? One of the similarities is that animals other than humans can also suffer from different types of animal diseases, the same as humans. People are worried mainly about the diseases that directly affect animals that are used for food, the diseases that affect pets, and the diseases that can be spread from animals to people.

Similarly to human diseases, animal diseases are divided into two groups as infectious animal diseases and noninfectious animal diseases. The doctors who treat the animal for various animal diseases caused by bacteria or any other disease or illness are known as veterinarians. These veterinarians can treat many diseases.

Let us read about these animal diseases in detail !

Types of Animal Diseases

In this article, we will discuss two types of animal diseases. First is Infectious diseases and another is Non-infectious diseases.

Infectious Diseases

The diseases that spread from one animal to another are called infectious diseases. These diseases are caused by particles known as viruses and tiny living things such as bacteria, protozoans, fungi, and worms.

Rabies is one of the most dangerous animal diseases. Rabies directly attacks the brain. A virus in the saliva of animals with bacteria causing rabies can also cause the disease. Rabies often spreads through animal bites. People can also get rabies disease. Luckily, there is a vaccine that can protect people as well as animals from rabies.

The other virus causes Newcastle disease, which is a disease that affects chickens, turkeys, as well as pet birds. The symptoms of Newcastle disease are the same as that of influenza or flu. People can also be affected by this disease from sick birds.

Tuberculosis is an animal disease caused by bacteria and mainly affects cattle. The disease is harmful to the lungs. To people, tuberculosis can spread through the milk of cows.

Non-Infectious Diseases

The diseases that cannot be spread from one animal to another are called non-infectious diseases. The non-infectious diseases in animals are much similar to that of the non-infectious diseases in humans. 

Non-infectious Diseases Examples:

A disease like cancer can affect many older dogs, cats, and other animals. Pets and many other wild animals can also suffer from arteriosclerosis. This arteriosclerosis is a disease in which the blood vessels become blocked. A cataract is a disease in which many animals over their eyes can develop cloudy growths.
