3 Causes of Coughing in Pigs and Steps to Take 2
2. Bordetella Bronchiseptica Causes Pig Coughing and Sneezing
Bordetella bronchiseptica is a bacterial disease that causes pig coughing and sneezing. Other symptoms of this infection in pigs are tear staining, epistaxis (nosebleed), fever of up to 104 F, and anorexia or extreme weight loss in pigs.

The pigs’ upper and lower respiratory tracts suffer the most from this pig respiratory infection. Unlike most other porcine respiratory diseases, this bacteria has a rapid onset and presents clinical symptoms as early as two to three days after exposure. This nasty bacteria causes two major disorders in pigs, namely, Bordetella rhinitis and Bordetella bronchitis.
Pigs of any age are susceptible to bordetella organism, however, it is more commonly seen in young pigs. If their immune systems are strong, the antibodies should help fight the infection.

However, the Bordetella organism makes the pig susceptible to other respiratory-related ailments and diseases if their immune system is weakened Bordetella bronchiseptica also causes inflammation of a pig’s airways, resulting in mucus build-up and coughing fits. The disease can lead to pulmonary infection and even death (worst-case scenario).
Bordetella bronchiseptica is highly contagious and can spread quickly through your herd. Bacteria can spread through contact with an infected pig or aerosols with infected droplets sprayed through sneezing and coughing.
The organism can survive for several months inside an infected pig. It can also most likely stay in humid conditions, moist surfaces, and water-rich soil. This means the disease can also be spread through fomites (clothing, objects, and vehicles).
Essentially, poor facilities and biosecurity, overcrowding, stress and inadequate nutrition are all factors that contribute to an outbreak of BB.

Quarantine pigs to avoid spreading the disease if any of your pigs show symptoms
Antibiotic treatment can help manage the symptoms of Bordetella Bronchiseptica in pigs. However, it’s important to note that BB is resistant to Ceftiofur and trimethoprim-sulfonamide combinations. Antibiotics such as Chlortetracycline help reduce the symptoms associated with BB, but they’re unsuccessful in clearing the respiratory tract infection.
