Bordetella bronchiseptica leads to respiratory illness in many species. It's linked to Bordetella pertussis, which causes whooping cough in people. Therefore, it's categorized as a rare zoonosis disease (transmittable from animals to humans). It is a disease-causing agent in dogs (one of the main causes of 'kennel cough'), cags, rabbits and pigs, and can occasionally cause illness in humans.
How Bordetella Spreads
When cats become infected with B. bronchiseptica, they shed germs through their nasal secretions and saliva (along with droplets when they sneeze). Therefore, transmission through inhalation or direct touch is common.
While the bacteria are susceptible to disinfectants, they are likely to persist in the environment for 1 to 2 weeks. Your cat's surroundings, bedding, grooming equipment, food bowls and other items may all be sources of illness if not meticulously cleaned.
Symptoms of Bordetella in Cats
The bordetella infection can cause coughing, nasal and ocular discharge, fever and mild sneezing in cats. However, in rare circumstances (especially in young kittens and in cats under intense stress), the infection may develop into more severe illness and become fatal. Symptoms often persist for 7 to 10 days.
Diagnosing Bordetella in Cats
The bacterium is detected in a laboratory using swabs collected from the pharynx. Bacterial culture (using a particular culture medium) or PCR (polymerase chain reaction - a molecular technique for detecting the bacterium's genetic material) can also be used to identify the bacterium.
Treatment for Bordetella in Cats
Antibacterial medicines are typically extremely successful in treating infections. Such medicines include Doxycycline (or maybe a fluoroquinolone antibiotic), which is likely to be the most effective treatment. However, because certain bacteria are resistant to some antibiotics, it is often preferable to do sensitivity testing in a laboratory. Bear in mind, though, that an extremely severe infection may require additional supportive care and hospitalization.
Most Bordetella infections are considered mild, and no special precautions are required for most cats since the risk of infection and serious illness is minimal.
However, there is never a guarantee that the vaccine will be risk-free. Consult your veterinarian on what the best option for your cat is.
