Diagnosis
If your newborn might have group B strep disease, a sample of your baby's blood or spinal fluid likely will be taken. A lab checks the sample for the bacteria that causes the infection.
If your baby appears ill, the baby might be given other tests, including:
- Urine culture.
- Lumbar puncture.
- Chest X-ray.
For adults who have an infection, a blood test can find out if group B strep is the cause. Learning the cause may be important for figuring out the right treatment.
Treatment
Infants
If your baby tests positive for group B strep, the baby receives IV antibiotics through a vein. Depending on your baby's condition, the baby might need IV fluids, oxygen or other medicines.
Adults
Antibiotics can treat group B strep infection in adults. The choice of antibiotic depends on the location and extent of the infection. It also depends on your specific circumstances.
If you're pregnant and you have medical problems because of group B strep, you'll likely receive antibiotics by mouth. Most often, you'll be given penicillin, amoxicillin (Amoxil, Larotid) or cephalexin. All are considered safe to take during pregnancy.
