Sketchy covers them in the "Mansion of Horrors."

If you are currently drowning in a sea of Staphylococcus , Streptococcus , and strange fungal spores, you have likely heard of the holy grail of visual learning: .

| Video # | Title | Key Organisms Covered | High-Yield Takeaway | | :--- | :--- | :--- | :--- | | 1.1 | Staphylococcus aureus | MRSA, Toxic Shock Syndrome, Scalded Skin | The "cannon" represents exotoxins. | | 1.2 | Staphylococcus epidermidis & Saprophyticus | Coagulase-negative Staph, UTIs (Saprophyticus) | The "toilet" in the basement = UTI in young women. | | 2.1 | Streptococcus pyogenes (Group A Strep) | Pharyngitis, Rheumatic Fever, Necrotizing Fasciitis | The "flying saucer" = M protein. | | 2.2 | Streptococcus agalactiae (Group B Strep) | Neonatal meningitis, Sepsis | The "baby on the boat" = Neonatal infection. | | 2.3 | Streptococcus pneumoniae | Pneumonia, Meningitis, Otitis Media | The "parrot" = Polysaccharide capsule. | | 2.4 | Viridans Group | Dental caries, Subacute endocarditis | The "tooth" = Dental plaque. | | 3.1 | Enterococcus faecalis & faecium | UTIs, Abdominal infections, VRE | The "pool ladder" = High salt tolerance. | These organisms are tricky because they look similar under a microscope. Sketchy uses the "Neisseria Neighborhood" to differentiate them.
