Staphylococcus: Aureus, Epidermidis, Saprophyticus

Official Ninja Nerd Website: https://ninjanerd.org You can find the NOTES and ILLUSTRATIONS for this lecture on our website at: https://www.ninjanerd.org/lecture/sta... Ninja Nerds! In this microbiology lecture, Professor Zach Murphy provides a high-yield breakdown of the clinically important Staphylococcus species, focusing on Staphylococcus aureus, Staphylococcus epidermidis, and Staphylococcus saprophyticus. These Gram-positive cocci are major players in both community-acquired and healthcare-associated infections. We begin with an overview of the Staphylococcus genus, including its Gram stain appearance, catalase positivity, grape-like clusters, and facultative anaerobic metabolism. From there, we compare and contrast the key members of this group. The lecture dives deep into S. aureus, covering its coagulase positivity, protein A, and virulence factors like toxins and enzymes. We review its wide range of clinical presentations—from skin and soft tissue infections to endocarditis, osteomyelitis, toxic shock syndrome, and pneumonia—along with its association with methicillin resistance (MRSA). Staphylococcus epidermidis is discussed in the context of biofilm formation and prosthetic device infections, while Staphylococcus saprophyticus is highlighted as a common cause of urinary tract infections, particularly in young sexually active women.
