Strep b group virus

Summary Invasive disease due to group B Streptococcus infection Streptococcus agalactiae results in a wide spectrum of clinical disease. Introduction Streptococcus agalactiae , also known as Group B Streptococcus GBS , was first differentiated from other streptococci by Rebecca Lancefield in the s after it was isolated from milk and cows with bovine mastitis 1.

Open in a separate window. Figure Streptococcus agalactiae colonization rates in pregnant women. Non-Pregnant Adults Although traditionally thought of as a disease afflicting infants and pregnant women, the incidence of GBS disease is increasing among non-pregnant adults, from 3. Older Adults Higher incidence rates of invasive GBS disease among persons ages 65 or older compared to the general non-pregnant adult population have been described in the US [ Figure 2 ], Canada, the United Kingdom, and multiple European countries 13 , — Neonatal Disease Group B Streptococcus is the leading etiology of culture-confirmed neonatal bacterial infection in the US and resulting in significant mortality Prevention of Neonatal Disease Due to the burden of GBS disease in neonates, preventative measures have been developed to minimize invasive disease.

Treatment Streptococcus agalactiae are uniformly regarded to be susceptible in vitro to penicillin, although reduced penicillin susceptibility has been detected in isolates from Japan, thought to be secondary to reduced Penicillin-Binding-Protein PBP 2X expression , References 1.

Epidemiol Infect — In some cases, however, group B strep can cause a urinary tract infection or other more-serious infections. Signs and symptoms of infections that may be caused by group B strep include the following. If you have signs or symptoms of group B strep infection — particularly if you're pregnant, you have a chronic medical condition or you're older than 65 — contact your doctor right away. If you notice your infant has signs or symptoms of group B strep disease, contact your baby's doctor immediately.

Many healthy people carry group B strep bacteria in their bodies. You might carry the bacteria in your body for a short time — it can come and go — or you might always have it.

Group B strep bacteria aren't sexually transmitted, and they're not spread through food or water. How the bacteria are spread to anyone other than newborns isn't known. Group B strep can spread to a baby during a vaginal delivery if the baby is exposed to — or swallows — fluids containing group B strep.

Adults age 65 and older are at increased risk of group B strep. You're also at increased risk of if you have a condition that impairs your immune system or other serious diseases, including the following:. If you're an older adult or you have a chronic health condition, group B strep bacteria can lead to any of the following conditions:.

If you're pregnant, the American College of Obstetricians and Gynecologists recommends a group B strep screening during weeks 36 to 37 of pregnancy. Your doctor will take swab samples from your vagina and rectum and send them to a lab for testing.
