Name “Bad Staph”( infect healthy people) and what it can cause
S. aureus. Skin infection,wound infection, sepsis, metastasize, toxic shock and nosocomial pathogen
Coagulase + and Catalase +
S. aureus
Name “Not so bad” Staphs(need predisposing factor to cause disease) and what it causes
S. epidermidis and S. saprophyticus
What does the two “Not so bad” Stap cause
S. epidermidis - Infections with indwelling plastic devices.
S. saprophyticus - UTIs in young women
What are the “Bad Strep”
Group A ( S. pyrogenes) and Group B (S. agalactiae)
Group A Strep location and what it causes
On mucous membrane and skin. Causes strep throat, scarlet fever and impetigo, rheumatic fever and glomerulonephritis
Group B Strep location and what it causes
Live in the colon and vagina. Causes sepsis and meningitis in neonates.
Sepsis, arthritis, meningitis in adults and diabetics
Leading cause of sepsis and meningitis in neonates
Group B Streptococcus
Not so bad Strep
Viridans Strep. (Alpha and Gamma hemolytic species)
What Strep is linked to colon cancer
S. bovis
World’s most antibiotic resistant bacteria
Enterococci
