Chains of S. pyogenes bacteria (orange) at 900× magnification Gram stain of Streptococcus pyogenes. Unlike most bacterial pathogens, S. pyogenes only infects humans. Thus, zoonotic transmission from an animal (or animal products) to a human is rare. [8] S. pyogenes typically colonizes the throat, genital mucosa, rectum, and skin. Of healthy ...
Streptococcus pyogenes (red-stained spheres) is responsible for many cases of severe puerperal fever. Specialty: Obstetrics: Symptoms: Fever, lower abdominal pain, bad-smelling vaginal discharge [1] Causes: Typically multiple types of bacteria [1] Risk factors: Caesarean section, premature rupture of membranes, prolonged labour, malnutrition ...
