Candida albicans
  • Routine examination of high vaginal swabs (HVS) includes microscopy for bacterial vaginosis (BV) and Trichomonas vaginalis (TV) and culture for Candida, Lancefield Groups A, C and G streptococci and Staphylococcus aureus
  • Endocervical swabs are required for the diagnosis of gonococcal infection. They are NOT an optimal sample for the diagnosis of Candida, BV or TV
  • Vulval swabs are cultured for Candida, Lancefield Groups A, C and G streptococci, Staphylococcus aureus and in children Haemophilus influenza
  • Urethral swabs are not normally required for microbiological investigation
  • IUCDs may be examined if Actinomyces infection is suspected
  • Listeria culture can be performed in cases of intrauterine death, septic abortion and miscarriage
