Staphylococcus hyicus is a Gram-positive, facultatively anaerobic bacterium in the genus Staphylococcus. It consists of clustered cocci and forms white circular colonies when grown on blood agar.[1] S. hyicus is a known animal pathogen. It causes disease in poultry,[2] cattle,[3] horses,[4] and pigs.[5] Most notably, it is the agent that causes porcine exudative epidermitis, also known as greasy pig disease, in piglets.[6] S. hyicus is generally considered to not be zoonotic,[1] however it has been shown to be able to cause bacteremia and sepsis in humans.[7][8]

Staphylococcus hyicus commonly infects pig herds worldwide due to its global distribution.[1] It can be found on asymptomatic carrier pigs at sites such as the skin, mucosa of nasal cavity, conjunctiva, and genitals (vagina of sow and prepuce of boar).[1][9]
Infection with S. hyicus can be prevented with an autogenous vaccine.[10][11] Managing the pigs can prevent disease and reduce the severity of an outbreak.[11] Treatment includes topical sprays and oils[12] as well as antibiotics, which should be tested to ensure S. hyicus is susceptible to them.[12][13][14]
