    <abstract locale="en_US">Background: Group&#xA0; B&#xA0; streptococcus&#xA0; (GBS)&#xA0; is&#xA0; one&#xA0; of&#xA0; the&#xA0; most&#xA0; important&#xA0; cause&#xA0; of&#xA0; morbidity&#xA0; and&#xA0; mortality&#xA0; among&#xA0; newborns&#xA0; especially&#xA0; in&#xA0; developing&#xA0; countries.&#xA0; It&#xA0; has&#xA0; been&#xA0; shown&#xA0; that&#xA0; the&#xA0; screening&#xA0; approach&#xA0; rather&#xA0; than&#xA0; the&#xA0; identification&#xA0; of&#xA0; maternal&#xA0; clinical&#xA0; risk&#xA0; factors&#xA0; for&#xA0; early-onset&#xA0; neonatal&#xA0; GBS&#xA0; disease&#xA0; is&#xA0; more&#xA0; effective&#xA0; in&#xA0; preventing&#xA0; early-onset&#xA0; GBS&#xA0; neonatal&#xA0; disease.&#xA0; The&#xA0; objective&#xA0; of&#xA0; this&#xA0; study&#xA0; was&#xA0; to&#xA0; detect&#xA0; GBS&#xA0; among&#xA0; clinical&#xA0; samples&#xA0; of&#xA0; women&#xA0; using&#xA0; PCR&#xA0; and&#xA0; standard&#xA0; microbiological&#xA0; culture.
Methods: Samples&#xA0; were&#xA0; taken&#xA0; from&#xA0; 375&#xA0; women&#xA0; at&#xA0; 28-38&#xA0; weeks&#xA0; of&#xA0; gestation&#xA0; during&#xA0; six month&#xA0; from&#xA0; January&#xA0; 15&#xA0; till&#xA0; June&#xA0; 15,&#xA0; 2011&#xA0; from&#xA0; a&#xA0; hospital&#xA0; in&#xA0; Tehran,&#xA0; Iran.&#xA0; Samples&#xA0; were&#xA0; tested&#xA0; by&#xA0; standard&#xA0; culture&#xA0; using&#xA0; Todd-Hewitt&#xA0; broth,&#xA0; blood&#xA0; agar&#xA0; and&#xA0; by&#xA0; PCR&#xA0; targeting&#xA0; the&#xA0; cfb&#xA0; gene.
Results: Among&#xA0; the&#xA0; 375&#xA0; women,&#xA0; 35&#xA0; (9.3%)&#xA0; were&#xA0; identified&#xA0; as&#xA0; carriers&#xA0; of&#xA0; group&#xA0; B&#xA0; streptococci&#xA0; on&#xA0; the&#xA0; basis&#xA0; of&#xA0; the&#xA0; results&#xA0; of&#xA0; the&#xA0; cultures&#xA0; of&#xA0; specimens,&#xA0; compared&#xA0; to&#xA0; 42&#xA0; (11.2 %)&#xA0; on&#xA0; the&#xA0; basis&#xA0; of&#xA0; PCR&#xA0; assay.
Conclusion: We&#xA0; found&#xA0; that&#xA0; GBS&#xA0; can&#xA0; be&#xA0; detected&#xA0; rapidly&#xA0; and&#xA0; reliably&#xA0; by&#xA0; a&#xA0; PCR&#xA0; assay&#xA0; in&#xA0; vaginal&#xA0; secretions&#xA0; from&#xA0; women&#xA0; at&#xA0; the&#xA0; time&#xA0; of&#xA0; delivery.&#xA0; This&#xA0; study&#xA0; also&#xA0; showed&#xA0; that&#xA0; the&#xA0; rate&#xA0; of&#xA0; incidence&#xA0; of&#xA0; GBS&#xA0; is&#xA0; high&#xA0; in&#xA0; Iranian&#xA0; women.</abstract>
