All are true regarding staphylococcal toxin except –
**Core Concept**
Staphylococcal toxins are a group of virulence factors produced by Staphylococcus aureus, a Gram-positive bacterium. These toxins play a crucial role in the pathogenesis of staphylococcal infections, including skin and soft tissue infections, pneumonia, and sepsis. Staphylococcal toxins can cause a range of symptoms, from mild to life-threatening.
**Why the Correct Answer is Right**
Staphylococcal toxins can be divided into several types, including alpha-toxin (also known as alpha-hemolysin), beta-toxin (also known as sphingomyelinase), gamma-toxin (also known as leucocidin), and delta-toxin. These toxins have distinct mechanisms of action and target different cellular components. For example, alpha-toxin forms pores in cell membranes, leading to cell lysis and death, while beta-toxin cleaves sphingomyelin, a key component of cell membranes.
