Epidemiology

Habitat

  • Inhabits the distal nasal passage, external nares, and skin especially near mucocutaneous borders such as the perineum, external genitalia and bovine udder.
  • May also transiently inhabit the gastrointestinal tract.

Lifecycle

  • Reproduction by binary fission.

Transmission

  • Spread by direct and indirect contact.
  • Many infections endogenous.
  • Rarely transmitted between species.

Pathological effects

  • Staphylococcus spp produce toxins and enzymes   →   variety of clinical syndromes, eg epidermolytic toxins in porcine exudative epidermitis due to S.hyieus and alpha toxin (hemolysin) is associated with gangrenous mastitis in cattle.
  • Pyogenic   →   abscess formation.
  • Wounds, burns, chronic debilitating disease and foreign body, eg suture   →   deep-seated invasive disease.
  • Endogenous or exogenous infection   →   suppurative conditions (in cattle, sheep, goats, pigs, horses, poultry, rabbits, dogs and cats).

Other Host Effects
