Is Bordetella In Cats Contagious To Humans?

Bordetella bronchiseptica (B. bronchiseptica) is a bacterium that causes respiratory disease in several animals, including cats. It is related to Bordetella pertussis and Bordetella parapertussis, which cause whooping cough in humans. While B. bronchiseptica rarely affects humans, it can be transmitted from animals to humans and is therefore classified as a rare zoonosis. The disease is contagious and can be spread through direct contact with infected cats, such as licking or nuzzling, or through the air via coughing or sneezing. Young kittens are particularly susceptible to the disease, which can cause severe respiratory issues and even lead to fatal bronchopneumonia.

Bordetella is a rare zoonosis (disease transmissible from animals to humans)

Bordetella is a rare zoonosis (a disease that can be transmitted from animals to humans). The Bordetella bronchiseptica (B. bronchiseptica) bacterium causes respiratory disease in a variety of animals, including dogs, cats, pigs, and rabbits, and can occasionally be transmitted to humans. It is a significant cause of "kennel cough" in dogs and can lead to severe respiratory infections in cats, particularly young kittens, old cats, or those with weak immune systems.

B. bronchiseptica is a highly contagious bacterium that spreads through direct contact between animals, such as licking and nuzzling, or through the air via coughing or sneezing. Cats infected with B. bronchiseptica shed bacteria in their saliva and nasal secretions, making direct contact or inhalation of infected droplets a common mode of transmission. The bacteria can survive in the environment for up to two weeks, contaminating surfaces like bedding, feeding bowls, and grooming utensils, which can further facilitate indirect transmission.

In cats, B. bronchiseptica typically causes mild symptoms, including sneezing, coughing, nasal and ocular discharge, and fever. These symptoms usually last for about 7 to 10 days. However, in vulnerable individuals, such as young kittens or immunocompromised cats, the infection can be more severe and even lead to life-threatening pneumonia. Pneumonia in cats infected with B. bronchiseptica is characterised by respiratory distress, loss of appetite, crackling lung sounds, moist cough, and swollen lymph nodes in the neck.

While B. bronchiseptica infections in cats are often mild, they can have serious consequences in rare cases. The bacteria can persist in cats for many months after the initial infection, and recovered cats can continue to shed the bacteria for up to 19 weeks, becoming long-term carriers and potential sources of infection for other animals and humans. Therefore, it is crucial to isolate infected cats, maintain excellent hygiene, and seek veterinary care if symptoms persist or worsen.

To prevent B. bronchiseptica infections, vaccination is available for cats in many countries. However, it is not commonly administered to adult cats due to the rarity of infection in this age group. Instead, veterinarians may recommend vaccinating young kittens in environments with a large number of cats, such as shelters or breeding colonies, where the risk of exposure is higher.

Symptoms of Bordetella in cats

Bordetella in cats, or feline bordetellosis, is a contagious bacterial disease that causes upper respiratory tract abnormalities. It is caused by the bacteria Bordetella bronchiseptica, which is related to the bacteria that cause whooping cough in humans. Young kittens, especially those living in unhygienic conditions, are most at risk of contracting the disease. However, any cat with a pre-existing airway disease is also susceptible to Bordetellosis, regardless of age.

Cats infected with Bordetella bronchiseptica shed the bacteria through their saliva, nasal secretions, and droplets when they sneeze, making direct touch or inhalation an efficient method of transmission. The bacteria can survive in the environment for up to two weeks, so it is important to keep the surroundings, bedding, food bowls, and grooming equipment clean to prevent the spread of the disease.

The symptoms of Bordetella in cats include mild sneezing, coughing, nasal and ocular discharge, and fever. In rare cases, especially in young kittens or cats under stress, the infection can be more severe and may even be fatal. Symptoms typically last for 7-10 days. In some cases, Bordetella can lead to more serious illnesses, such as pneumonia, if left untreated.

Other symptoms of Bordetella in cats include:

• Loss of appetite (anorexia)
• Difficulty breathing
• Crackling lung sounds, moist cough, or wheezing
• Swelling of the lymph nodes in the neck or under the jaw
• Watery nasal discharge
• Fever and lethargy in severe cases

How Bordetella is transmitted

Bordetella, or more specifically, Bordetella bronchiseptica (B. bronchiseptica), is a highly contagious bacterium that can cause upper respiratory tract infections in cats. It is related to the bacterium that causes whooping cough in humans. While Bordetella typically affects dogs, it can also be transmitted between dogs and cats. Cats kept in large groups, such as in rescue shelters or breeding households, are more susceptible to contracting and spreading the infection.

Bordetella is transmitted through direct or indirect contact. Direct contact includes licking and nuzzling, as infected cats can shed the bacteria in their saliva and nasal secretions. Indirect contact occurs when a cat inhales infectious airborne particles produced by coughing or sneezing. The bacteria can also be transmitted through contaminated objects and surfaces, such as feeding bowls, bedding, and grooming utensils. It is important to note that Bordetella can survive in the environment for up to 1-2 weeks, so maintaining a clean and disinfected environment is crucial to prevent its spread.

In addition to direct and indirect contact, Bordetella can be transmitted between different species. While rare, cats can potentially transmit the bacterium to humans and other members of the household. Therefore, it is essential to keep a sick cat away from young children, the elderly, or anyone with a weakened immune system. Practicing good hygiene, such as regularly washing hands and disinfecting surfaces, is crucial to prevent the spread of the bacterium to other members of the household.

Young kittens, especially those living in unhygienic conditions, are highly susceptible to Bordetella and can develop severe respiratory infections. Kittens with Bordetella may experience mild symptoms such as sneezing, coughing, nasal and ocular discharge, fever, and loss of appetite. In more severe cases, they can develop life-threatening bronchopneumonia. Therefore, it is imperative to consult a veterinarian if your kitten exhibits any of these symptoms.

To prevent the spread of Bordetella, it is recommended to vaccinate cats, especially those living in environments with a high risk of exposure, such as shelters or breeding colonies. Maintaining excellent hygiene practices and isolating sick cats can also help minimize the risk of transmission.

Treatment for cats with Bordetella

Bordetella, or Bordetella bronchiseptica, is a bacterium that can cause disease in a number of animals, including cats, and occasionally in humans. It is related to Bordetella pertussis and Bordetella parapertussis, which cause whooping cough in humans. B. bronchiseptica is a cause of kennel cough in cats and can lead to upper respiratory tract infections. Young kittens are particularly susceptible to infection and can develop severe and even fatal respiratory infections.

If you suspect your cat has contracted Bordetella, you should contact your veterinarian immediately, especially if your cat is a young kitten or has a weak immune system. Your veterinarian will perform a thorough physical examination, which will include listening to the cat's lungs and heart as it breathes. They will also take a swab from the inside of the cat's mouth or nasal discharge to test for the presence of Bordetella bacteria. A chest X-ray may also be recommended.

Treatment for Bordetella in cats typically includes:

• Antibacterial therapy: Even if the symptoms are mild, antibacterial therapy is recommended. Doxycycline is the antimicrobial medication of choice. In some cases, a fluoroquinolone antibiotic may be used.
• Supportive care: Cats with severe infections may require supportive care and intensive nursing care, including fluid therapy.
• Hospitalisation: In severe cases, hospitalisation may be necessary to provide additional care and monitoring.
• Isolation and rest: Cats with Bordetella should be isolated from other pets and active children and allowed to rest in a quiet place for at least two to three weeks or until their lungs appear normal on X-rays.
• Vaccination: While not routinely recommended for all cats, vaccination against Bordetella may be advised for young kittens in high-risk environments, such as shelters or breeding colonies.

In most cases, cats with uncomplicated infections should begin to recover within two weeks. However, it is important to monitor your cat's recovery and contact your veterinarian if symptoms persist or worsen. Additionally, cats with Bordetella may continue to shed the bacteria for up to 19 weeks after the initial infection, so isolation from other cats is crucial to prevent the spread of the disease.

Preventing the spread of Bordetella

Bordetella is a highly contagious bacterium that can cause upper respiratory tract infections in cats, otherwise known as kennel cough. It is spread through direct contact (licking, nuzzling) and airborne transmission (coughing, sneezing). It can also be spread through contaminated surfaces.

To prevent the spread of Bordetella, it is important to:

• Keep cats individually or in small isolated groups to minimise the risk of infection.
• Maintain excellent hygiene practices, including the use of appropriate disinfectants, to reduce the risk of environmental contamination.
• Isolate any cats showing signs of clinical disease, such as coughing, sneezing, nasal or ocular discharge, fever, and loss of appetite.
• Consult a veterinarian if you suspect your cat is infected, as they may recommend antimicrobial medication and fluid therapy.
• Vaccinate your cat against Bordetella, especially if they are at high risk of exposure, such as in shelters or breeding colonies.
• Wash your hands thoroughly after handling your cat, their food and water dishes, bedding, and toys.
• Keep your cat away from young children, the elderly, and anyone with a compromised immune system if they are sick.
