Greasy pig disease (exudative epidermitis) is a skin infection in pigs induced by the bacteria Staphylococcus hyicus (S. hyicus). It is the most common skin infection in pigs and affects suckling pigs and piglets in particular.
It is important to note that resistance to the most commonly used antibiotics is frequently seen. The choice of antibiotics should consequently depend on the result of a resistance test.
Greasy pig disease is infectious and the bacteria can survive in the housing environment for a long time. Therefore, a high standard of hygiene is important in the pen sections affected, including washing and disinfecting between pig herds. Litter-by-litter introduction in weaning pens should be considered in problem herds. Quarantining diseased animals helps reduce transmission of infection to healthy animals.
