Pleuropneumonia / Shipping Fever
Pleuropneumonia is a severe bacterial infection of the lung and pleura, in which inflammation and fluid/pus accumulate in the chest cavity. It often occurs after long transports with a fixed, raised head (shipping fever) and is a potentially life-threatening disease that must be treated quickly by a vet.
Veterinary care required
This condition belongs in veterinary diagnosis and treatment. Compounds are at most supportive.
Priority · vet & management
Pleuropneumonia is an urgent veterinary EMERGENCY — with fever, breathing difficulty and chest pain after transport, call the vet immediately. Diagnosis (ultrasound, thoracocentesis, lab) and therapy (including antibiosis, possibly drainage) belong solely in veterinary hands; the earlier the treatment, the better the outlook. Complementary feeds have no role in the acute phase.
Possible causes
- · bacterial infection of the deep airways (often Streptococcus equi zooepidemicus and anaerobes)
- · long transports with a permanently raised head (impaired self-cleaning)
- · stress and weakened defences after transport/competition
- · pre-existing airway irritation or infection
Supportive compounds · supplementary feed, not medication

Transport breaks with a lowered head, shorter journey times, good ventilation and low-dust hay, as well as avoiding transport with an existing infection, markedly lower the risk of shipping fever.
Equiterna's take
Equiterna keeps pleuropneumonia strictly as an emergency with a clear transport link — compounds at most concern antioxidant support during convalescence, never the acute therapy.
