Summary: | Group B streptococcal infection (Streptococcus agalactiae) is one of the leading causes of
life-threatening disease in the early neonatal period, resulting in sepsis, pneumonia, and meningitis.
During invasive infections, an excessive release of pro-inflammatory cytokine, such as interleukin-6
(IL-6), thus IL-6 gene is significant, as a diagnostic marker of systemic infection of the newborns.
The present study aimed to describe the epidemiology diagnostic of GBS disease in neonatal by phenotypic
and genotypic methods. Nine hundred and ninety-six samples were taken at Maternity and
Children Hospital, Jeddah, Saudi Arabia for a period of one year (2011–2012). Results indicated
that out of 217 infected samples, twenty (9.23.0%) were positive for group B Streptococci bacteria.
This study also shows that female infants are more susceptible than males. The level of IL-6 was
higher in mothers above 30 years. Twenty positive Streptococci group B isolates showed bands with
the cylE gene primers in the border between 228 bp, 267 bp and 50 bp. Molecular detection by Real
time polymerase chain reaction was also done to detect the target (Sip gene) encoding the Sip
surface immunogenic protein. Specific primers and TaqMan probe were chosen for this purpose.
A Real-time PCR method targeting the sip gene of GBS in neonates after delivery has been
evaluated. |
