What is pseudomembrane?

How is streptococcal pharyngitis diagnosed?

Which antibiotics treat pharyngitis?
Antibiotic Options for GABHS Pharyngitis
|Drug||Class of antimicrobial||Duration of therapy|
|Amoxicillin||Penicillin (broad spectrum)||10 days|
|Penicillin G benzathine (Bicillin L-A)||Penicillin||One dose|

What does a pseudomembrane look like?
A pseudomembrane is formed when inflammatory exudate rich in fibrin coagulates on the conjunctiva. This is seen as a thin yellow-white membrane in the fornices and palpebral conjunctiva that can be readily peeled off, leaving an intact underlying epithelium with minimal bleeding.
Can pseudomembrane go away on its own?
Most cases of viral conjunctivitis are mild and resolve spontaneously within 2 weeks. Severe cases of viral conjunctivitis can cause subepithelial corneal opacities and pseudomembrane formation. Treatment for viral conjunctivitis is generally supportive, with artificial tears and compresses for the eyelids.
Is streptococcal pharyngitis bacterial or viral?
