U01.03.023 Staphylococcus saprophyticus Staphylococcus saprophyticus is a Gram-positive, catalase-positive, coagulase-negative cocci that is part of the normal genital flora. It is a common cause of urinary tract infections (UTIs) in sexually active young women. Unlike S. epidermidis, it is novobiocin-resistant, which helps differentiate between coagulase-negative staphylococci in laboratory diagnosis.

U01.03.022 Staphylococcus epidermidis Staphylococcus epidermidis is a Gram-positive, catalase-positive, coagulase-negative cocci that is part of the normal skin flora. It commonly causes infections associated with prosthetic devices, catheters, and heart valves due to its ability to form biofilms. It is typically novobiocin-sensitive and an important cause of nosocomial infections.

U01.03.021 Staphylococcus aureus Staphylococcus aureus is a Gram-positive, catalase-positive, coagulase-positive cocci that forms golden-yellow colonies. It causes a range of infections, from skin abscesses and pneumonia to toxic shock syndrome and food poisoning. Its virulence factors include protein A, coagulase, and toxins such as TSST-1 and exfoliative toxin. Methicillin-resistant S. aureus (MRSA) is notable for β-lactam antibiotic resistance.

U01.03.018 Gram-positive lab algorithm Drag and drop each diagnostic test into the correct box to identify how it differentiates between the given bacterial groups. Focus on Gram-positive cocci — Staphylococcus, Streptococcus, and Enterococcus. Match each test to the correct key distinguishing feature, such as enzyme activity, antibiotic sensitivity, or growth pattern on specific media. This exercise helps reinforce laboratory identification methods crucial for microbiology exams and USMLE Step 1.

U01.03.016 Features of exotoxins and endotoxins Match each bacterial exotoxin to its causative organism and mechanism of pathogenesis. Focus on how these toxins act at the cellular level — whether they block neurotransmission, inhibit protein synthesis, or alter intracellular signaling (like cAMP). Understanding these mechanisms is essential for mastering microbiology concepts in USMLE Step 1 and clinical reasoning.

My little guys 🫶 I know my environmental isolate is probably just S. aureus but let a girl romanize the bacteria she has been focusing on for most of a semester. #grampositive
