Background and aims: Fixed Orthodontic Appliances (FOA) act as diverse impact zones and modify microbial adherence and colonization, acting as unfamiliar reserves and potential sources of infection  This study was conducted to inspect the effect of the introduction of fixed orthodontic appliances on the growth and adherence (biofilm formation) of Candida species. And also to reveal the species distribution and antifungal sensitivity to isolated Candida species.  Material and methods: The trial group was chosen   from orthodontic patients whom were inspected clinically as soon as to get baseline information prior to active treatment. The group included 210 patients; 165 females, and 45 males, (mean age 21.6 ± 4.5 years). Clinical, demographic, and risk factor data were collected in a standard questionnaire and then each individual was directed to perform an oral rinse with phosphate-buffered saline, which was expectorated and processed proposed for the isolation and identification of Candida species by standard methods. After that, the isolated Candida species were tested for biofilm production by the phenotypic method i.e. Tissue culture palate methods (TCPM). Finally, antibiogram susceptibility pattern of oral Candida species was done by Kirby-Bauer disc diffusion method for amphotericin B, ketoconazole, and fluconazole. Results: The most common yeast colonized oral cavity after the introduction of FOA was C. albicans (72.5%), followed by C. glabrata and C. tropicalis  (12.5%), while Candida parapsilosis  only was 2.5%. The rate of formation of biofilms was 52.5% for all types of Candida, and it was found that biofilm formation occurs more frequently among C. tropicals  and C. glabrata (60%) than C. albicans (48.3%). All Candida species isolates were sensitive to amphotericin B and ketoconazole while resistance to fluconazole was found in 40% of C. tropicalis and 20% in C. glabrata  and 13.8% in C. albicans.  Conclusion: The present study proved that C. albicans is still the major isolate from the oral cavity after the introduction of FOA, but non-albicans species colonization is raised and FOA might be a factor for biofilm formation. The C. tropicalis and C. glabrata were more– biofilm-producers compared to C. albicans. The isolated species in the current study are less susceptible to fluconazole and drug resistant factor in the Candida species isolates was found to be associated with  biofilm formation.

Objectives:  The objective of this study was to assess the oral Candida albicans colonization ( OCAC)  in a cluster of teenagers and young adults while being treated with a fixed orthodontic appliance (FOA). Subjects and methods:  The investigational group was selected from orthodontic patients whom were examined clinically as soon as to get baseline information before active treatment.  The cluster included 210 patients; 45 males, 165 females (mean age 21.6 ± 4.5 years).  Clinical, demographic data and risk factors were collected in standard questionnaire then each individual was directed to carry out oral wash by a phosphate-buffered saline solution, which was expectorated and processed intended for the isolation of Candida species on Sabouraud’s dextrose agar. The isolated Candida species were identifying by culturing on chromogenic Candida agar and notice species-specific colony natures. Results:  The predominant Candida species isolated was C. albicans with OCAC rate equal to 13.8% extensively enhanced after the insertion of a FOA, as revealed by the oral rinse (P < 0.05) techniques. The results also revealed an increase of OCAC in male patients (24.4%) than female patients (10.9%),   21-25 years patients (17.1%), and regular smoking and Qat chewing were significant associated risk factors (OR=28.6, OR=10.7 respectively , P < 0.0001).  There was no significant association between C. albicans  colonization with oral hygiene in fixed Orthodontic patients. Conclusion:  As a whole, the current data suggest that the introduction of FOA is likely to promote OCAC. Moreover, it becomes visible that the routine oral hygiene procedures performed by these patients may not necessarily reduce OCAC while smoking and chewing Qat habits significantly increased OCAC in FOA. Also smoking and Qat chewing during FOA treatment should be banned if potential harmful effects are to be prevented. Further work with a larger sample size is required to confirm or deny these results.

Background and objective: Women at pregnancy are further susceptible to vaginal colonization and yeast infection. The responsibility of Candida colonization in the incidence of preterm birth is correctly established. Knowing regional epidemiology and identifying risk factors of preterm birth are important for management and preventive strategies. The aim of the study was to reveal the prevalence of Candida species in vaginal swabs of pregnant women and determine odds ratio of risks for vulvovaginal candidiasis (VVC). Methods:   Pregnant women attendance routine antenatal visits in Al-Olify –family Center in Sana'a city were registered into a cross-sectional study carried out from June 2018 to March 2019. The laboratory works were carried out in the National Center of Public Laboratories (NCPHL). Samples of vaginal swabs were taken from contributors after obtaining oral consent. The classification of the Candida species was done by culture on HiCrome Candida Differential Agar at 35 °C for 48 h for making of species-specific colors. Data of demographic, clinical and risk factors were collected in a pre-designed questionnaire. Results: A total of 190 pregnant women are included. The rate of VVC was 51.6%. Candida albicans accounted for 39.5% and non-Candida albicans accounted for 12.1% of isolates, mainly C. glabrata (4.7%), C. lipolytica (3.2%), and C. famata (2.1%). When VVC risk factors were considered, there were significant risk factors with the age group 20-24 years (61%, odds ratio (OR) = 1.8), first trimester of pregnancy (61.1%, OR = 1.7), Multipara of  parity (61.8%, OR = 1.9), low socioeconomic level (60.1%, OR =2.4), and illiteracy (68%, OR = 2.2). When clinical symptoms were considered, only 86.2% of affected females had clinical signs of VVC. Conclusions: There is a high probable rate of VVC is found among pregnant women in Yemen, undiagnosed and unnoticed; and this highlights the need for health authorities to develop strategies for diagnosing VVC, including vaginal swabs for candidiasis as a routine procedure for all pregnant women. This study also revealed a steady increase in time with a non-C. albicans species  prevalence rate. VVC syndrome management guidelines in Yemen should be revised to include a special protocol for pregnant women.

The outbreak of diseases caused by Candida species is growing. These opportunistic pathogens can produce biofilm on non-biological surfaces, such as removable orthodontic appliances. Over the past two decades, there has been a significant increase in resistance to several types of antifungal drugs. Recently, there is a growing interest in using herbal plants and their extracts as an alternative to antifungal drugs. A common plant is basil, which belongs to Lamiaceae family. This study aimed to determine the effect of basil extracts on the adhesion of C. albicans and C. dubliniensis to acrylic surfaces of removable orthodontic appliances. Basil dried leaves were macerated in ethanol to extract its constituent, and then the extract was dissolved in water and fractioned by other solvents, including n-hexane and ethyl acetate, successively. The minimum inhibitory concentrations (MIC) of the extracts against standard species of Candida were determined by the broth microdilution method based on clinical and laboratory standard institute (CLSI) protocol. Afterward, adherence and biofilm formation tests were done on acrylic specimens in the vicinity of proper concentration of fractions with the help of the Crystal Violet and spectrophotometry method. MIC for ethyl acetate fraction, n-hexane fraction, ethanol crude extract, and the aqueous fraction was 1024, 2048, ≥2048, >2048 µg/ml, respectively. Inhibition of adherence and biofilm formation for Candida albicans and Candida dubliniensis in the vicinity of ethyl acetate fraction was 73% and 78%, respectively. In the vicinity of n-hexane fraction was 65% and 78%, respectively. Two fractions could inhibit the growth, adherence, and biofilm formation of two Candida species.

  Background and Purpose: Candida dubliniensis is closely related to the most pathogenic and prevalent yeast, namely C. albicans. Candida species can opportunistically overgrow in vulnerable individuals and cause a variety of diseases. The current study aimed to identify and isolate C. dubliniensis species present in the Candida albicans species complex identified in the oral cavity of drug abusers. Materials and Methods: This study was conducted on 53 strains of C. albicans species complex, isolated from the oral mucosa of drug abusers in Isfahan, Iran. DNA extraction was accomplished through boiling procedure. Duplex polymerase chain reaction (PCR) was performed to amplify ITS1-5.8S-ITS2 region using four specific primers. Fungal species were identified based on the difference in the size of the bands created in the Agarose gel. Results: Out of the 53 isolates under study, 30 (56.6%) and 14 (26.4%) samples were identified as C. albicans and C. dubliniensis, respectively. In the remaining 9 samples (17%), both types of Candida species were confirmed. Conclusion: The findings of the present study revealed the presence of a noticeable amount of C. dubliniensis in the oral cavity of drug abusers. Therefore, the probable presence of this fungus should be considered during the examination of oral infection among this group. To date, no research has directly investigated this issue in Iran.

Background: Candida species are common inhabitants of the normal oral microbiota. A few studies founded a relationship between high levels of Candida albicans in the oral cavity and high DMF scores. Toothbrushes can also be reservoirs of microorganisms, the proliferation of these microorganism on a toothbrush could be a major factor for its distribution in the oral cavity. Aim: To examine the associations between salivary Candida and DMF, and between salivary Candida and Candida in the toothbrush. Method: 46 healthy school children, who attended a University pediatric dental clinic, were tested for Candida in their saliva and in their toothbrush. Their DMF was recorded. Results: 38 children were Candida-positive (79.2%), out of whom 5 demonstrated a positive growth of Candida in the toothbrushes. No correlation was found between Candida in the saliva and in the toothbrush. The number of Candida-positive girls was significantly higher than the number in boys. No significant relationship between caries experience and the presence of Candida was found. Conclusions: No correlation was found between Candida in the saliva and in the toothbrush. The origin of the Candida in the toothbrush is not totally clear.

Background and objectives: Vulvovaginal candidiasis is known to be a global issue of concern due to its association with economic costs, sexually transmitted diseases, and the escalation of genital tract infections.  This study aimed to determine the prevalence, species distribution and risk factors associated with Candida species causing vulvovaginal candidiasis. Subjects and Methods:  Non-pregnant women attending routine antenatal visits at Al-Olaifi-Family Center in Sana'a were enrolled in a cross-sectional study conducted from June 2018 to March 2019. Laboratory work was carried out at the National Center of Public Laboratories (NCPHL). Vaginal swabs were sampled from participants after oral consent was obtained. The swabs were inoculated in Sabouraud glucose agar supplemented with chloramphenicol and incubated at 37°C for 24 to 48 h under aerobic conditions in order to perform a fungal culture. Candida species were determined by culturing on HiCrome Candida differential Agar at 35°C for 48 h to produce species-specific colours. Data on demographic, clinical, and risk factors were collected in a pre-designed questionnaire. Results:  A total of 190 non-pregnant women were included. The prevalence of VVC was 22.1%. Candida albicans accounted for 16.3% and non-Candida albicans accounted for 5.8% of the isolates, mainly C. glabrata (3.2%), C. rugosa (1.05%), C. lipolytica (1.05%), and C. dubliniensis (0.53%). When VVC risk factors were considered, there were significant risk factors with age group 30-34 years (33.3%, odds ratio=2.1) and age group  ≥35 years (62.5%, odds ratio=10.3), residence in a rural area (39.5 %, OR=3.3), negative emotions (30.2%, OR=2.3), underwear replacement over 1 day (29.3%, OR=4.2), impure cotton underwear (29.4%, OR=4.9), while Condom use and vulvar cleaning before or after sexual life were found to be highly significant protective factors against VVC (p=0.008, 0.03, respectively). Conclusions: Guidelines for the management of VVC syndrome in Yemen should be revised to include a protocol specifically for women over 30 years of age. VVC undoubtedly poses a significant threat to women's reproductive health. Risk factors for VVC are varied, and include ages, health habits, history of the disease, and other aspects. It is necessary to take appropriate measures to avoid risk factors and to help reduce the prevalence of VVC among women of childbearing age.                    Peer Review History: Received: 3 May 2021; Revised: 23 June; Accepted: 30 June, Available online: 15 July 2021 Academic Editor: Dr. Ali Abdullah Al-yahawi, Al-Razi university, Department of Pharmacy, Yemen, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Introduction: -Oral candidiasis is an infection of oral cavity caused by an over growth of candida species. The proportions of yeast in the periodontal pockets are similar to some of periodontal bacteria, thus suggesting the possible role of Candida species in pathogenesis of periodontal pocket. The plant extract such as garlic and propolis, contain bioactive components which act against these organisms with no or less side effects than by the conventional antibiotics. Objectives: - To evaluate the efficacy of garlic and propolis extracts against candida albicans and compare it with Amphotericin-B as control at 3 different concentrations Methodology: - Subgingival plaque samples were collected and selectively cultivated for candida albicans. The antimicrobial activity of propolis and garlic was assessed and compared with Amphotericin-B. Conclusion: Garlic extract can be used as a potent agent in the eradication of candida albicans in chronic periodontitis patient.
