Abstract
The study employed herein was carried out on 100 pregnant women; all of them were suffering from vaginal candidiasis admitted to Gynaecology and Obstetrics Department in Zagazig University Hospitals. 61% of women tested were rural, while 39%were urban. This showed that the environmental conditions and social reasons affected disease spreading. Cultures showed that out of the 100 patients tested, 49 patients only showed Candida infection. Percentage values of VC were 10.2%; 59%; 30.8% in the age ranges 16 – 20 years; 21 – 30 years; 31 – 40 years respectively. Moreover, the study group assimilated 30 women; 19 women were multigravidae; primigravidae respectively. The highest prevalence of VC was found in the third trimester in 29 women (59.2%) followed by the second trimester in 14 patient (28.5%), while the lower prevalence was found in the first trimester in 6 patients (12.3%).
According to phenotypic and biochemical differentiation, the 49 Candida isolates could be classified into three groups. Group1 included 32 isolates, all of them formed germ tubes, grew on BIGGY agar and formed dark brown colonies and could be identified as C. albicans strains. group 2, included 5 isolates and formed germ tubes and grew well on BIGGY agar with formation of light brown colonies; they identified as belonging to C. dubliniensis. group 3 included 12 isolates; they did not form germ tubes and could be identified as following C. tropicalis. The identification of the 49 Candida isolates was approved by API-Candida kits. The results obtained confirmed the preliminary identification by morphological and cultural criteria. After identification processes, the prevalence of each Candida sp. within total number of Candida strains (49 isolates) was obtained. group 1; group 2; group 3 assimilating C. albicans (32 isolates); C. dubliniensis (5 isolates); C. tropicalis (12 isolates) showed an incidence percentages within total 100 patients suffering from candidiasis by 32%; 5%; 12% respectively and a prevalence percentages within total 49 Candida isolates identified by 65.3 %; 10.2 %; 24.5 % respectively .
