“…It can be related to geographical conditions, social and cultural factors, hygiene customs, and diagnostic techniques (18,19). The prevalence of infection has been reported as 12.1% in Athens, 17.4% in Turkey, 12.2% in Brazil, 20.4% in India, 18.7% in Israel, and 6.5% in China (3,(18)(19)(20)(21)(22). Candida albicans can be found in the cultures of vaginal discharge of 25% of pregnant women (16).…”

Background: Vulvovaginal candidiasis is a widespread and frequent infection affecting up to 70% of healthy women, and some of them affected by recurring resistant forms of the disease. The main risk factors are hormone replacement therapy, diabetes mellitus, antibiotic usage, pregnancy, oral-contraceptives, and insufficient therapy. Candida albicans is the most etiologic agent of Candida vaginitis capable of colonizing on the mucous membrane of genitourinary tracts of healthy humans. The aim of the present study is to identify Candida species obtained from patients with vulvovaginitis by molecular techniques. Methods: Between 2015 -2016, 108 suspected patients were evaluated for vulvovaginal candidiasis. Suspected patients were divided into 3 groups and each group took only 1 antifungal agent including clotrimazole, miconazole, and nystatin, respectively. Direct microscopic examination, culture, and fragment size polymorphism (FSP) technique were used for identification of clinical isolates Results: Of the 108 patients, 59 (54.6%) had both positive culture and direct microscopic examination. The duration of disease was between 3 to 365 days. Candida albicans was the most prevalent Candida species isolated from patients (74.5%) followed by Candida glabrata (17%). The correlation between the kind of antifungal agents and recovery of patients was not statistically significant (P value = 0.056). Conclusions: Resistance to various antifungal agents and emerging of non-albicans Candida species among clinical specimens are crucial affairs in the field of medical mycology. Since VVC is a prevalent and recurrent infection, controlling of predisposing factors, personal hygiene, and appropriate antifungal therapy are extremely recommended among vulnerable population.

“…Las infecciones vaginales son comunes en las mujeres de todas las edades y por su frecuencia destacan aquellas debidas a Trichomonas (protozoo), Candida (hongo) y bacterias [5][6][7][8][9][10][11][12][13][14][15][16]. En ocasiones la vulvovaginitis es de origen multifactorial, lo que dificulta el diagnóstico y favorece la cronicidad del proceso.…”

“…En ocasiones la vulvovaginitis es de origen multifactorial, lo que dificulta el diagnóstico y favorece la cronicidad del proceso. Candida spp, se presenta aproximadamente en un tercio de las pacientes diagnosticadas con vulvovaginitis [5,9,[13][14][17][18][19][20][21][22][23][24][25][26]. Ocasionalmente se reportan casos de candidosis en el aparato genital masculino [3]; un estudio efectuado en 478 hombres demostró a Candida en el 26% como colonizante y en 18% como causante de balanitis [27].…”

Las levaduras del género Candida causan enfermedades en los humanos que abarcan desde infecciones superficiales no graves, hasta sistémicas y potencialmente mortales. La candidiasis o candidosis, es el origen común de enfermedad vaginal y aunque es una infección no considerada como incapacitante, suele causar síntomas molestos que alteran la conducta del paciente. En México se considera la única micosis de reporte obligatorio ante las autoridades sanitarias. Por lo anterior, en este trabajo se efectuó una revisión bibliográfica para conocer el estado del arte de la vulvovaginitis causada por Candida spp. (VVC), y ofrecer una breve descripción acerca de la frecuencia presentada por esta infección en diversos países de Latinoamérica, con especial énfasis en México. Se muestra que las frecuencias de VVC en Latinoamérica, son muy parecidas a las reportadas en países como Estados Unidos de América; asimismo, Candida albicans sigue prevaleciendo como el principal agente etiológico. Las diferencias encontradas entre países desarrollados con respecto a los latinoamericanos, consisten básicamente en los métodos diagnósticos y el tipo de tratamiento. Desafortunadamente, en México, a pesar de que la VVC ocupa el noveno lugar entre las 20 principales causas de enfermedad del país, en muy pocos casos se efectúa la identificación de la especie causante, lo que constituye un dato de importancia epidemiológica, considerado como la base para investigar los factores que aumentan el riesgo de contagio, en especial por especies Candida no-albicans y para determinar si la enfermedad es prevenible o controlable.

The aim of the present study was to evaluate the role of microbial enzymes in normal and abnormal cervicovaginal fluids of cervical dysplasia. The cervicovaginal infections were evaluated through the estimation of microbial enzymes in patients with and without abnormal cervical cytology like bacterial and fungal infections. The patients were categorized based on infection caused by organism and stages of dysplasia. The pH, Whiff test, and Pap smear tests were conducted for normal and abnormal cervical swabs based on standard protocols. Microbial enzymes include mucinase, sialidases, and proteases of the cervical swabs and are estimated according to standard methods. The results of abnormal cervical cytological smears showed increased pH and the presence of amines with different levels of Pap smear test. Increased levels of microbial enzymes were observed in patients with abnormal cytology than normal cytology. Three microbial enzymes mucinase, sialidase, and protease were significantly (P < 0.01) more elevated in patients with bacterial infections (8.97 ± 0.64, 10.39 ± 0.28, 8.12 ± 0.64) than without dysplasia (2.02 ± 0.8, 1.98 ± 0.3, 1.96 ± 0.8). The results reinforce that the microbial infection seems to be more prone to cervical dysplasia and may act as risk-factor for the development of cervical cancer along with HPV infection.
