Pneumonia, or inflammation of the lungs, is not usually encountered in hamsters. When it does occur, it is typically the result of an infection with one or more kinds of bacteria, sometimes in conjunction with viruses or other types of infectious agents. These infections are especially hard for the hamster to fight off when there are stress-inducing changes to the environment, such as a sudden change in room temperature.
Because pneumonia is contagious, separating those that are suffering from the condition is important for preventing and controlling outbreaks. It is also vital that you keep their cages and living area clean.
Pneumonia in hamsters is usually the result of an infection with one or more kinds of bacteria, sometimes in conjunction with viruses or other types of infectious agents. It is then transmitted into the air by a pneumonic hamster sneezing and/or coughing. It is important to note that stress increases the chances for the development of pneumonic symptoms in hamsters.
In addition to a thorough physical examination of the hamster, special laboratory tests can help confirm a diagnosis of pneumonia. This may include examining discharge from the eyes or nose or blood samples, from which the causative organism may be identified. X-rays may also confirm the presence of pneumonia in the lungs.
