摘要:

It has been reported that bacteria may attach to motile spermatozoa, be carried through the cervix and uterus to the fallopian tubes, and cause acute salpingitis. In an attempt to mimic these conditions in vitro, we incubatedEscherichia coli, Streptococcus faecalis, Pseudomonas aeruginosa, andStaphylococcus aureuswith motile spermatozoa which then were allowed to migrate through a capillary filled with bovine cervical mucus. After satisfactory sperm migration through the mucus, the capillaries were broken and cultured at different distances from the original insemination site. Mucus fractions in proximity to bacterial inocula grew varying amounts of the pathogens. More distal fractions of mucus columns were generally culture-negative even though they contained motile sperm which had been exposed to bacteria. Migration of spermatozoa exposed to bacteria through bovine cervical mucus did not result in enhanced bacterial penetration.

摘要:

Four hundred thirty-one parturient women were tested for cervical infection with group B streptococcus using standard bacterial culture and a commercially available latex particle agglutination test. The total time required to perform each latex test was 30 minutes or less. The prevalence of endo- cervical group B streptococcus by culture was 4.4%, half of whom developed clinically significant group B streptococcus infection; all such cases were identified correctly by the latex test. The predictive value of a negative latex test for a negative group B streptococcus culture was 98%. This method seems promising as a rapid intrapartum diagnostic test for ruling out group B streptococcus infection and thus avoiding unnecessary antibiotic treatment.
