What is the best antibiotic for resistant strep?

Can you be a permanent strep carrier?

Yes. You can pass the strep infection to other people until you have been treated appropriately with an antibiotic. Children who have strep throat should not go back to school or day care until their fever has gone away and they have taken an antibiotic for at least 24 hours.

What is the best treatment for Group B streptococcus colonization during pregnancy?

Eradication of maternal Group B streptococcal colonization was a strategy first investigated two decades ago (22, 24, 27). Well designed clinical studies utilized oral antibiotics to treat colonized mothers during the second or third trimester of pregnancy.

Which penicillin is used to treat Group B streptococcus?

Since Group B Streptococcus remain universally susceptible to penicillins, penicillin G as single therapy is considered the treatment of choice for established Group B streptococcal infections ( 29 , 33 ).

What is the difference between strep throat culture and rapid strep?

A throat culture takes time to see if group A strep bacteria grow from the swab. While it takes more time, a throat culture sometimes finds infections that the rapid strep test misses.
