- Subclinical amniotic fluid infection and subsequent preterm labour may occur with intact membranes. We report two cases of subclinical amniotic fluid infection with intact membranes presenting in preterm labour. Capnocytophaga species, fastidious Gram-negative bacilli normally found in oral flora, were isolated in pure culture from amniotic fluid obtained by transabdominal amniocentesis. The distinctive microbiological features and spectrum of infections associated with Capnocytophaga species, and the importance of recognition of subclinical amniotic fluid infection as a cause of preterm labour, are discussed.
