  1. March 2016: The temperature for Incubation of S. aureus was changed to 35-37°C, from 35°C. Staphylococcus aureus is highly vulnerable to destruction by heat treatment and nearly all sanitizing.
  2. Staphylococcus aureus is a coagulase-positive, catalase-positive, Gram-positive cocci that occur singly or in pairs, tetrads, short chains, and grape-like clusters.S. aureus can produce a variety of syndromes with clinical manifestations, including skin and soft tissue infections, empyema, bloodstream infections, pneumonia, osteomyelitis, septic arthritis, endocarditis, sepsis, and meningitis
  3. MSA contains a high concentration of salt (NaCl), and therefore, selects for the growth of microbes that can tolerate high salt concentrations. Staphylococcus species are halotolerant, whereas Streptococcus species and many other organisms are inhibited by high concentrations of NaCl. MSA also differentiates on the basis of mannitol fermentation
  4. Fighting Staphylococcus aureus in its most antibiotic-resistant form has been a priority for the healthcare community since the strain began defying drug treatment in recent decades.New research from the Imperial College of London (ICL) now offers a promising novel approach in the fight against methicillin-resistant Staphylococcus aureus (MRSA), and their weapon is salt
