Texas Barber Exam Practice Test

The most common pus forming bacteria are?

1. Escherichia coli

2. Streptococci

3. Staphylococci

4. Salmonella

The correct answer is: Staphylococci

Staphylococci are the most common pus-forming bacteria. Staphylococci are gram-positive spherical bacteria that commonly cause skin infections such as boils and abscesses, which can result in the formation of pus. Escherichia coli and Salmonella are forms of bacteria that are not typically associated with pus formation. Streptococci, while also capable of causing skin infections, are not as commonly associated with pus formation as Staphylococci.
