There are several possibilities. Despite the lack of evidence, you could have a partially resistant variety of Strep type A. Even though you are feeling better after taking the antibiotics, the infection is never completely clearing. The fact that you and your daughter have had a total of 7 episodes strongly suggests that you may be re-infecting each other. The cultures for carrier status may not have been appropriately timed to detect the strep. Also it
We have the same problem. My two older boys have had strep 3 times and I have had it 3 times as well. I had my Ducts cleaned and am going to an allergist before we have the surgery. I am stressed about it...Are there alternatives?
Thanks for you comments. We have no pets, in fact avoid pets because my son is allergic. No impetigo. We're so careful about hygeine at this point we're headed toward OCD. We changed milks (to organic). Can strep be in our water filter or hiding in some other unsuspected place in our home? There is such a huge difference in our recovery between the times we get on Penicillin immediately and when we have to wait 24 hours for a culture result that I push for the former. But in light of the article you sent, should we wait (and suffer much longer) a day or two to prevent recurrence? I so appreciate your time and help.
I have no idea about the water filter. You could try bottled water for awhile and see.
I can't really comment on waiting a couple of days as I'm NOT a doctor. I only pointed out the article as I thought it was interesting.
What does your pediatrician say about all of this?
I am assuming that, by "positive" strep cultures, you're referring to cultures reported as having Group A beta strep (some labs report it by the genus/species Streptococcus pyogenes). Some labs report "beta strep not group A" on their strep screens. There are other beta streptococci, especially group C, that can cause a nasty throat, but do not produce the sequelae of rheumatic fever/glomerulonephritis.
Pets can carry strep. Try culturing your dog if you have one. Your vet can do this for you.

Does anyone have impetigo? Check out this site:

This is an excellent article:
http://www.emedicine.com/ped/topic2702.htm
"Children with untreated acute infections spread organisms by airborne salivary droplet and nasal discharge. The incubation period for pharyngitis is 2-5 days. Children are usually not infectious within 24 hours after appropriate antibiotic therapy has been started, an observation that has important implications for return to the daycare or school environment. Individuals who are streptococcal carriers (chronic asymptomatic pharyngeal and nasopharyngeal colonization) are not usually at risk of spreading disease to others because of the generally small reservoir of often-avirulent organisms. Fingernails and the perianal region can harbor streptococci and play a role in disseminating impetigo. Multiple streptococcal infections in the same family are common. Both impetigo and pharyngitis are more likely to occur among children living in crowded homes and in poor hygienic conditions."
Pay particular attention to your child's hygiene - handwashing and bathroom hygiene. Perhaps this may be playing a role. Fingernails should be short and clean. Kids are just not very attentive with this stuff, especially at early school age, so parents have to make sure. My daughter used to just wet her toothbrush and tell me she brushed her teeth when she was in second or third grade. She's 25 now and has no idea why she did this back then; she just did.
The sequelae of untreated Group A beta strep are acute rheumatic fever and acute glomerulonephritis, so you can't NOT treat this organism.
From the same article - an interesting paragraph:
"Sometimes families express concern regarding the delay of 24-48 hours that is required to obtain a result of throat culture. Clinicians therefore feel pressure to initiate therapy immediately, prior to obtaining the result of the culture. However, because treatment of group A streptococcal sore throat as long as 9 days after onset of symptoms still effectively prevents rheumatic fever, initiation of antibiotics is seldom of urgent importance. Early antibiotic therapy may have beneficial effects in relieving symptoms and allowing an earlier return to school or daycare; however, early antibiotic therapy may have disadvantages as well. Several controlled studies have shown that children receiving immediate antibiotic therapy are more likely to have symptomatic recurrences in the months following treatment than are children who delay the initiation of therapy by 48 hours."
Hope this gives you some ideas.
