Impact of antimicrobial therapy on nasopharyngeal carriage of Streptococcus pneumoniae, Haemophilus influenzae, and Branhamella catarrhalis
in children with respiratory tract infections.
An extract of Sambucus nigra L (black elderberry) was found to have antimicrobial activity in vitro against the gram-positive bacteria Streptococcus pyogenes and group C and G Streptococci, against the grarn-negative bacterium Branhamella catarrhalis
, and against human influenza viruses.
The 3 most common bacteria in AOM are Streptococcus pneumoniae, Haemophilus species, and Branhamella catarrhalis
. A recent study showed that both bacteria and viruses were isolated in the middle ear fluid of 65% of children with otitis media.
Hemophilus influenzae, Streptococcus pneumoniae, Branhamella catarrhalis
, and Staphylococcus aureus were cultured in 66.7% of nasopharyngeal smears from group B, and in 46.5% from group A.
