I've encountered this bug a few times, mostly in wounds and blood cultures.
I would think that in a lot of labs this would get mis-identified. In our
lab one of our rotators called it a beta Strep not group A and when I
followed up a couple of days later I found the bug and correctly identified
it in a blood culture. I went back to the other culture and re-identified it
and had to correct the report.
I'm not too sure about throat cultures though. I've been told by several
docs that the only thing we should look for is Strep Group A. Did you take a
swab and look at the culture? Could you talk to your micro lab supervisor
and ask if A. hemo. is a possibility?

Does anyone know anything about this bacterium? Arcanobacterium Haemolyticum
My 16 yr old daughter is having a tonsillectomy next week and I have a
sneaking suspicion this is the cause.
She started having tonsillitis about a year ago and the diagnosis was Strep
A based on observation not on testing. Penicillin in pill form didn't work
for her so we proceeded to use Penicillin IM. This went on about every three
months. Being an MT specializing in Microbiology I finally decided to do
some research myself but all I could find was an older article on Medscape
where it was included in an article about Rhodococcus Equi. It indicated
that this is a common (?) co-infection in people 15 to 30 yrs who have been
diagnosed with Group A or other beta hemolytic streps. Also with Mono, which
my daughter also had , confirmed by testing. It says that there are reports
of treatment failure with Penicillin and the DOC is Erythromycin. It also
says that it must be specifically sought in appropriate specimens to obtain
an accurate diagnosis.
My concern is that we do not routinely screen throat cultures for this
organism. I was wondering if any other labs do? And if they do, what
documentation they have that I could give to our Microbiologist to convince
him we should be.
As a mother I am upset that this was overlooked and now my daughter has to
have surgery instead of a different antibiotic. As a professional I want to
do all I can to save other patients from the same fate. Maybe it is all so
simple as my GP doc should have known about it and treated her
accordingly...they are just human after all...but if it is our mistake by
not screening for it I would like to correct that.
Thanks for your time and in advance for your input. Any comments would be
