“…An unrelated yeast, Rhodotorula mucilaginosa, was also isolated. This species, considered non-virulent and saprophytic, was found in the genital region of 13.5% of asymptomatic people [64]. However, new studies show that it can be opportunistic [65,66].…”

Vulvovaginal candidiasis (VVC), considered the second cause of genital infection among women, has pathogenic mechanisms still to be elucidated and unknown risk factors. Prevalence studies with laboratory diagnosis (at first diagnosis and recurrence) are uncommon, especially using MALDI TOF, used in this clinical, epidemiological, and laboratory study for evaluating candidiasis, and identifying unknown risk factors. To obtain clinical and epidemiological data, patients were questioned, and there was material collection. Samples collected were identified by using phenotypic and presumptive methods and confirmed by MALDI TOF. This study analyzed 278 patients, divided into symptomatic (n = 173) and asymptomatic (n = 105) groups. Regarding the main candidiasis symptoms (discharge, itching, and burning), only 50.3% of patients described these concomitant symptoms, showing a positive predictive value of 67.8%. Regarding the risk factors investigated, there was a statistical correlation between candidiasis and dairy products, gut transit, contraceptive use, respiratory allergy, and panty liners, describing new risk factors related to intestinal and vaginal dysbiosis. After Candida species analysis and confirmation, the primary prevalence was 80.9% (Candida albicans), 15.2% (non-albicans), 1% (Rhodotorula mucilaginosa), and 1.9% (unidentified species). In recurrence, the prevalence was 66.7% (C. albicans) and 33.3% (non-albicans). The presence of symptoms has low positive predictive value for the diagnosis of candidiasis, even when considering the classic triad of symptoms. Laboratory identification of yeast species is essential for correct treatment, preventing the resistance to antifungals and the high recurrence. In addition, dairy products and bowel habits, both related to intestinal and vaginal dysbiosis, may be associated with VVC.

“…The delivery mode also influences the fungal composition of children’s skin. In 1-year-old children, the mean relative abundances of Candida and Rhodoturula , the main fungi inhabiting the vagina ( 46 , 47 ), were higher in vaginally born children than in caesarean-born children; the skin-associated fungal genus Malassezia ( 35 ) and airborne genera Alternaria and Aspergillus ( 42 , 48 ) exhibited the opposite trend. Based on the correlation analysis between children and mothers, the vagina-associated genera Candida and Rhodotorula were significantly correlated between vaginally born children from the younger group aged 1 to 3 and their mothers.…”

“…Vulvar samples taken from four healthy women recovered Lactobacillus crispatus and Lactobacillus iners as the most frequent bacterial organisms; 70.5 -97% and 28.3-96.2% of these clones respectively, reported the same phylotype found in labia minora (23). Moreover, yeast species were not frequently isolated from genital areas 23 ; Bentubo (2015), in a sample taken in Brazil, examined the presence of this organisms in genital regions, reportedly…”

Impact of genital hair removal on female skin microenvironment: barrier disruption and risk of infection, a literature review

Genital hair is one of the secondary sexual traits that marks the beginning of puberty; its removal has been part of human culture since ancient times. This practice may lead to modifications in vaginal microbiome with potential repercussions on skin health and balance. We conducted a narrative review with the purpose of describing normal skin microbiota, its impact under microenvironment changes and genital hair removal. Menses, pathological conditions and pubic hair removal may alter vaginal microbiota, being the latter of special relevance giving the risk of hair microtrauma, irritations and potential spread of infectious agents.
