Case of Exudative Epidermitis in a Young Wild Boar from a Spanish Game Estate

22 January 2014

A case report about exudative epidermitis in a young wild boar in Spain, which presented with signs of respiratory infection in addition to the greasy brown exudate on the skin found in domestic pigs with the condition.

Exudative epidermitis, a porcine disease caused by Staphylococcus hyicus, produces serious economic losses in severely affected herds.

In a report in Journal of Swine Health and Production, David Risco Pérez from the University of Extremadura in Spain and co-authors describe a case of exudative epidermitis in a wild boar presenting specific clinical signs.

The affected animal was a female approximately six months old, with greasy brown exudates around the mouth and eyes and on the neck and legs, separation of the horn at the bulbs of the heels, necrosis of the tips of the pinnae and tail, and focal ulcerative stomatitis.

Multiple septic emboli and necrotic foci were observed in the lung.

Staphylococcus hyicus isolates were obtained from affected skin and lungs.

This disease and others that occur on wild boar farms, while similar to those described in domestic pigs, tend to produce specific clinical signs in wild boar, such as the pneumonic lesions in this case. Exudative epidermitis in this animal was aggravated by these pneumonic lesions.

The increasing economic relevance of wild boar farming has led to an increase in the occurrence of infectious diseases, concluded Dr Pérez and co-authors. 

They added that knowledge of the epidemiological, clinical and pathological manifestations in wild boar will facilitate prevention, diagnosis and treatment, reducing the impact on animal health and economics in this new niche of swine production.
