Staphylococcus hyicus

Staphylococcus hyicus is a Gram-positive member of the bacterial genus Staphylococcus consisting of clustered cocci. Originally isolated from skin infections in pigs and named Micrococcus hyicus, the species was moved to its present genus on the basis of phenotypic similarities.[1]

S. hyicus is a known animal pathogen. It causes skin disease in cattle,[2] horses,[3] and pigs.[4] Most notably, it is the agent that causes exudative dermatitis, also known as greasy pig disease, in piglets.[5]

Commonly impacting pigs, a study suggests that Greasy pig disease (exudative epidermitis), known as a localized skin disease shows main correlation with Staphylococcus hyicus. Although previous treatments were done to piglets with skin lesions, a sudden rise to antimicrobial resistance towards beta-lactam antibiotics was frequently observed in S.hyicus and S. aureus. The study offers the view of plant essential oils having the ability to potentiate the effect of antimicrobial compounds against the two species of Staphylococcus. Results showed mainly essential oils consisting of cinnamon, thyme, and winter savory being most active with minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC). [6]
