Chromogenic Candida agar (OCCA) is a novel medium facilitating isolation and identification of Candida albicans, C. tropicalis, and C. krusei, as well

This study aimed to evaluate the mixed and homogeneous application of the inactivated SARS-CoV-2 vaccine CoronaVac (CV) and the mRNA vaccine BNT162b2 (BNT). This prospective cohort study included 235 health care workers who had received two prime shots with CoronaVac. They were divided into three cohorts after the third month: Cohort-I (CV/CV); Cohort-II (CV/CV/CV); and Cohort-III (CV/CV/BNT). Anti-S-RBD-IgG and total anti-spike/anti-nucleocapsid-IgG antibody concentrations were examined in vaccinated health workers at the 1st, 3rd, and 6th months following the second dose of the vaccination. The mean age of 235 health care workers who participated in the project was 39.51 ± 10.39 (min-max: 22–64). At the end of the 6th month, no antibodies were detected in 16.7% of Cohort-I participants, and anti-S-RDB IgG levels showed a decrease of 60% compared to the levels of the 3rd month. The antibody concentrations of the 6th month were found to have increased by an average of 5.13 times compared to the 3rd-month levels in Cohort-II and 20.4 times in Cohort-III. The heterologous vaccination strategy “CoronaVac and BNT162b2 regimen” is able to induce a stronger humoral immune response and it will help remove inequalities in the developing world where CoronaVac was the initial prime.

This study aimed to determine the prevalence of yeast fungi in samples from the glans penis and prepuce of circumcised and uncircumcised children. Impression preparations were made on modified Dixon and Leeming-Notman agar without cycloheximide. The isolates were identified by morphological and physiological characteristics. The yeasts were detected in 32 (28.6%) of 112 children, 12 (18.2%) being among 66 circumcised and 20 (43.5%) among 46 uncircumcised children. The most common species was Malassezia globosa (40.6%) followed by, Malassezia furfur (31.3%), Malassezia slooffiae (15.6%), Candida albicans (6.3%), Candida tropicalis (3.1%) and Candida parapsilosis (3.1%). The colonization with yeasts, and especially lipophilic species was more frequently observed among uncircumcised versus circumcised children. While age was not found to be a factor (P>0.05), circumcision was responsible for increasing the colonization rate by 4.8 times (95% CI: 1.6–14.5) (P <0.01). The circumcision status was not found to effect the distribution of Malassezia spp.
