Streptococcus Pyogens: Clinical manifestation, Diagnosis and Treatment

It is a non suppurative inflammation spreading along the subcutaneous tissue planes and across intercellular spaces.

The term is a misnomer, as the lesion is one of the connective and interstitial tissue and not of the cells.

The causative organism is mostly the streptococcus pyogenes, through a variety of aerobic and anaerobic bacteria may produce cellulitis.

Ans. is ‘d’ i.e., Resistant to bacitracin

• Streptococcus pyogenes is bacitracin sensitive.
• All other options are correct.

Ans. is ‘c’ i.e., Streptococcus pyogenes 

Ans. B: Streptococcus pyogenes

The primary site of invasion of human body by streptococcus pyogenes is the throat.

Primary bacterial pathogens that account for approximately 30% of cases of pharyngitis include Streptococcus pyogenes /Group A Beta Hemolytic Streptococci (common), group C streptococci (uncommon), group G streptococci (uncommon), Neisseria gonorrhoeae (uncommon), Corynebacterium diphtheriae (rare), and Corynebacterium hemolyticum (extremely rare). Viruses are isolated in approximately 40% of cases and include rhinovirus, adenovirus, parainfluenza virus, coxsackievirus, coronavirus, echovirus, herpes simplex virus, Epstein-Barr virus (mononucleosis), and cytomegalovirus. Other probable copathogens for pharyngitis in children include Staphylococcus aureus, Haemophilus influenzae, Branhamella catarrhalis, Bacteroides fragilis, Bacteroides oralis, Bacteroides melaninogenicus, Fusobacterium species, and Peptostreptococcus species.

Ans. is ‘b’ i.e., Streptococcus pyogenes

Infections caused by streptococcus pvogenes

1. Respiratory infections

• Sore throat is the most common of streptocococcal disease . It may be localised as tonsillitis as in older children and adults or it may involve the pharynx more diffusely (pharyngitis) as in younger children. Otitis media
