Pseudomonas aeruginosa Infection in Chinchillas

In chinchillas, infection with Pseudomonas aeruginosais bacteria is the most common bacterial infection. This is mainly because Pseudomonas aeruginosa are mainly found in unclean environments, and when the immunity of the chinchillas is compromised or reduced, the bacteria gain an upper hand and cause disease. The infection may be passed by direct contact or contaminated fecal droppings. Young kits may get it by nursing from an infected mother.

Since Pseudomonas aeruginosa infection spreads quickly among the chinchillas it is necessary to immediately segregate the infected chinchillas from the normal ones. To prevent infection, maintaining good cleanliness and good sanitary condition inside the cages is necessary.

Pseudomonas aeruginosa is a disease-producing bacteria found in unclean drinking water and cages or contaminated fecal droppings. It typically affects chinchillas with weakened or immature immune systems. Young kits may also get it by nursing from an infected mother.


Your veterinarian would carefully observe the clinical signs for any involvement of internal organs. Blood tests may be taken to detect the presence of Pseudomonas aeruginosa. Alternatively, swabs may be collected from the ulcers in the skin or conjunctival swabs may be taken for culturing in suitable medium. Confirmation is based on a positive identification of colonies of Pseudomonas aeruginosa bacteria.
