Transmission of group B streptococci among parturient women and their neonates

The influence of Group B streptococcal-carriership on pregnancy outcome

“…Although these newborns are supposed to be at higher risk for infection and their colonization rate was high in our study, none of them developed GBS related disease. Other determinants of pregnancy outcome such äs gestational age, birth weight and the APGARscores were equal in both children-groups and therefor do not seem to be influenced by maternal carriership which is in accordance with other authors findings [1,6]. The number of artificial deliveries tended to be higher among the positive mothers, but this was not significant.…”

“…The most important moment of transmission from the mother to the newborn seems to be the time of delivery, when the newborn passes through the birth canal. It has been shown that cervix, vagina, rectum and urethra are important reservoirs of GBS in pregnant women [3,6,11]. Maternal factors influencing the transmission of GBS to the newborn are persistent carriership [11], theheaviness and the number of sites of colonization [2,11], Other factors such äs sex, race, lengthofgeStation and birth weight of infants do not seem to influence the acquisition of GBS [l, 5,6].…”

Streptococcal infection in young pigs: IV. An outbreak of streptococcal meningitis in weaned pigs

“…Previous work has shown that most conventionally reared pigs older than 6-8 weeks are immune to type 1 (Agarwal, Elliott & Lachmann, 1969). Their apparent lack of immunity to type 2 is puzzling but a similar association of particular serological types with different age groups has been noted in human neonatal infection caused by group B streptococci (Baker & Barrett, 1973, 1974Wilkinson, Facklam & Worthem, 1973). In infants less than 5 days old with group B streptococcal septicaemia ('early onset' type) Baker and Barrett found no significant difference in the incidence of type II and type III cocci (44 % and 33 % respectively).…”
