PREVALENCE AND DISTRIBUTION OF CANDIDA ISOLATES FROM HIGH VAGINAL SWAB SAMPLES OF SOME WOMEN IN NNEWI, ANAMBRA STATE, NIGERIA.
Journal Title: European Journal of Biomedical and Pharmaceutical Sciences - Year 2017, Vol 4, Issue 11
Abstract
Candida species normally colonize the skin and mucosal surfaces of humans in an asymptomatic manner but can become a most significant cause of disabling and lethal infection in immuno-suppressed persons. This study was designed to determine the prevalence and distribution of Candida isolates from some women attending Life Specialist Hospital, Nnewi, Nigeria. Ninety nine (99) high vaginal swab (HVS) samples were collected from HIV-negative (76 pregnant and 23 non-pregnant/apparently healthy) women in Nnewi. Samples were cultured on appropriate media and identified using standard techniques. Statistical analysis was done using Chi-square test (p<0.05). A total of 33 of the 99 participants were colonized with Candida species giving a prevalence of 33.3% while a total of 34 Candida isolates were recovered. The prevalence of vaginal Candida isolates among the pregnant and non- pregnant women was 36.8% and 21.7% respectively with the age group 26-35 years (in pregnant women) having the highest prevalence. Meanwhile, pregnant women in their second trimester had the highest prevalence. Candida tropicalis was the most frequently isolated species (13; 38.3%) followed by C. albicans (11; 32.4%), C. glabrata (4; 11.8%), C. krusei (4; 11.8%), C. dubliniensis (1; 2.9%) and C. kefyr (1; 2.9%). The prevalence of non-albicans Candida (NAC) species was 67.6%. This study suggests that all pregnant women be subjected to routine laboratory tests to rule out the possibility of vaginal Candida infection and also that proper identification of yeasts to species level be done since more non-albicans species of Candida are now implicated in many infections.
