Abstract:
Objective: To investigate the candidal infection status in puerperas in Lanzhou, and the candidal transmission from mothers to their newborn infants. Methods: Vaginal fluid and saliva samples from 104 puerperas, as well as 104 saliva samples from their newborn infants were collected. The Candida species were cultured, isolated and identified using CHROMagar media. Further identification was done using molecular biological method. Results; In 81 of 312 specimens (104 x2 from mothers and 104 from infants), Candida species were found. 39.42% (41 cases) was observed in the vaginal fluid and 33.65% (35 cases) was in saliva of puerperas respectively, and 21. 15% (22 cases) in both vagina and oral cavity. 4.81% (5 cases) was found in oral cavities of newborn infants. The distribution of Candida species were 53 Candida albicans, 33 Candida glabrata, 2 Candida krusei and 1 Candida tropical. In 2 pairs of mother-infant, the same genotype of Candida ablicans was identified using PCR method. Conclusion; The Candida detection rate of newborn infants and transmission rate from mothers to their neonates in Lanzhou are higher than that reported in other areas. The colonization of Candida in newborn infants is relevant to both horizontal and vertical transmission. It can decrease the possibility of Candidal infection in newborn infants by controlling the Candidal transmission in hospital and preventing the infection in pregnant women.
