Moraxella catarrhalis, Haemophilus influenza, and Alloiococcus otitidis are classified as fastidious Bacteria.
Alloiococcus otitidis was first isolated from an ear fluid sample of a child in a clinical study addressing otitis media in Buffalo State, America [12].
(2002) examined the prevalence of Alloiococcus otitidis, Moraxella catarrhalis, Streptococcus pneumoniae and Haemophilus influenza with the application of culture and Multiplex PCR methods.
Furthermore, no instance of Alloiococcus otitidis was observed after the application of culture method.
The aim of the present study was to compare culture and Multiplex PCR methods to detect Alloiococcus otitidis, Moraxella catarrhalis, and Haemophilus influenza as three fastidious pathogens causing otitis.
Alloiococcus otitidis has small alpha-hemolytic colonies on blood agar plate, which are observable after 2-5 days of incubation.
Three new bacteria have been proposed as important pathogens in otitis media: Corynebacterium mucifaciens, Pseudomonas otitidis, and Alloiococcus otitidis:
Alloiococcus otitidis. A otitidis is a slowly growing, fastidious, aerobic gram-positive bacterium.
Infection by Alloiococcus otitidis was initially suspected, but specific biochemical tests and antibiotic susceptibility data argued against this hypothesis (data not shown).
However, recent descriptions of another possible pathogen, Alloiococcus otitidis, in significant numbers of children with AOM and otitis media with effusion in Finland, Japan, and Australia have generated debate as to the significance of this new bacterium.
One interesting discovery that we made by using DNA-based detection was that Alloiococcus otitidis is extremely common in healthy ear canals; only Turicella otitidis and Coryneform bacteria are more common.
