Is it normal for a doctor not to do a throat culture when you have an infection? My doctor said he'll do one if the antibiotics don't work, so is it?

Culture: Sometimes it is easy to rule out a bacterial infection with accuracy by history and physical alone, and you don't need a throat culture. It is always a good idea to check a throat culture prior to prescribing antibiotics though. ...Read more

Med assit called and my throat culture was haemophilus parainfluenza 2. Worried because I don't know what this means. Amoxicillin for 7 days so far.

Med assit called and my throat culture was haemophilus parainfluenza 2. Worried because I don't know what this means. Amoxicillin for 7 days so far.

H. parainfluenzae: Haemophilus parainfluenzae, is a common bacteria found normally in the oropharynx. It probably is NOT the germ responsible for your pharyngitis, although I hope by now after 7 days of antibiotics you're better. Various viruses (mono) and bacteria (Strep A) would be on my list - were they checked for? A related bacteria known as Haemophilus influenzae IS a pathogen (a real germ) but u don't have it ...Read more

I saw a doctor yesterday and was diagnosed with pharyngitis. Still waiting for strep throat culture to come back. Pain is worst. Can hardly swallow.?

Can be other things.: Strep is not the only cause of pharyngitis. Herpes simplex, chlamydia, ebv, corynebacterium diptheriae, and many others can also cause it. That is one reason why the strep check swab is done, as well as a strep culture. Your doctor should be able to do this/should have done this rapid check so you can start treatment if positive. See your doctor soon if it gets worse for empiric treatment. ...Read more

If a throat culture is growing something but not certain what yet, does that automatically mean ill need antibiotics?

If a throat culture is growing something but not certain what yet, does that automatically mean ill need antibiotics?

Not necessarily.: The throat swab can detect bacterial infections, but if positive it does not mean that you need antibiotics. If the cutlure is 'contaminated' then it may grow multiple organisms but in that case you may not need antibiotics. If it grows Group A Strep then you will likely needs a course of treatment. Also make sure to continue supportive care for your symptoms (tylenol, salt water gargles, etc) ...Read more

My 2 year old son had a throat culture that came back with a high reading of pseudomonas, is this a sign of cystic fibrosis?

Is it common to test positive for strep a on rapid strep and a month later test positive for strep c on throat culture?

Not unusual: Group C strep is frequently found on throat culture and is part of the normal flora that reside in the throat.

There is no evidence Group C strep causes Acute Rheumatic Fever. *If it is cultured in an asymptomatic individual there is no necessity to treat it unless it's suspected as the cause. ...Read more

Took a throat culture today and said I either have strep throat or mono. How will I know which one I have?

One or Other or Both: You can't have either a strep throat or mononucleosis. You can have one or the other or both. A rapid strep test or a throat culture will tell whether or not you have a strep throat. A mono spot test or ebv antibody panel will show whether or not you have mono. If you have both do not take Ampicillin or Amoxicillin because either will cause a rash 90% of the time. ...Read more

Positive strep throat culture, is floxacin an antibiotic for this?

Not one I would use: This class of drugs have a broad range of effects against many types of germs but I find no listing for strep throat. It is not used in kids and rarely used in most simple infections. Since strep is universally sensitive to the penicillins, and other inexpensive medications, it is one I would never use for strep throat. ...Read more
