<s>[INST] I am 10 weeks and just found out via culture that I had a low amount of beta strep b. I am not going to use an antibiotic at this time because unfortunately I break out in a yeast rash on my neck, back, face, and arms from antibiotic use. (so annoying and gross). Can you tell me more about beta strep b and the risks involved during pregnancy? Thanks! [/INST] Hi there,Since you have strep B infection during pregnancy, you need to keep some points in mind. The worry with group B streptococcus(GBS) is that if present in pregnant women especially during the last few weeks it can be transmitted to the baby during delivery and can cause infection in baby called meningitis and septicemia which are quite serious. So, you need to take antibiotics in labor through the intravenous route to prevent the transmission of these bacteria to your baby. The usual antibiotic given is penicillin, but if you are allergies an alternative is given. It would be advisable to take antibiotic for the strep b infection now also, and you could consider taking it with a local antifungal cream for the thrush, especially if you have grouped B strep in your urine culture. Do remember to repeat strep b culture at 36 weeks, and please inform your obstetrician that you have had this infection during this pregnancy, to make sure you get intrapartum antibiotics to prevent transmission of bacteria to your baby. Hope this helps. Regards. </s>
