Kingella kingae is a species of Gram-negative facultative anaerobic β-hemolytic coccobacilli. First isolated in 1960 by Elizabeth O. King , it was not recognized as a significant cause of infection in young children until the 1990s, when culture techniques had improved enough for it to be recognized.
E. meningoseptica grows well on blood agar and chocolate agar. Colonies are very pale yellow and may not be easily evident at 24 hours. Strains growing better at 40 °C are mostly associated with invasive meningitis. [7] Often, a greyish discoloration is seen around the colonies on blood agar due to proteases and gelatinase.

E. anophelis also produces OxyR regulon and antioxidants as a stress response to defend against the oxidative stress that can be associated with mosquitoes during the process of blood digestion. One study suggests that features of E. anophelis including growth, hydrogen peroxide tolerance, cell attachment, and biofilm formation are due to the ...
