Introduction. In the recent decade, the increased immunocompromised population such as diabetic patients makes a high incidence of invasive Candida infections. Diabetes mellitus is the most common endocrine metabolic disorder, and diabetic patients are more susceptible to oral candidiasis infection. Candidiasis is an opportunistic fungal infection caused by many species of Candida. Secretion of exoenzymes plays an important role in the virulence and pathogenesis of Candida species. The aim of this study was to evaluate the potential role of phospholipase, esterase, and hemolytic activity of Candida species isolated from oral cavity lesions of diabetic patients. Methods. A total of 108 Candida species including 75 Candida albicans and 33 non-Candida albicans species were recovered from the oral cavity of diabetic patients included in our study. Egg yolk agar, Tween 80 opacity medium, and blood agar plate assays were used for determining phospholipase, esterase, and hemolytic activities, respectively. Results. Candida albicans species had the most exoenzyme activity in comparison to non-albicans isolates. Candida albicans isolates showed 97.3%, 100%, and 77.3% phospholipase, hemolysin, and esterase activities, respectively. The difference between Candida albicans and non-Candida albicans was significant in phospholipase ( P < 0.001 ) and hemolytic activity ( P = 0.027 ), but not significant in esterase activity ( P = 0.076 ). Conclusion. This study showed that most of the isolates had different enzymatic patterns, and Candida albicans isolates had the most exoenzyme activity. So due to the potential effects of these enzymes in pathogenesis and virulence effects of Candida species, we can conclude that the severity of extracellular enzymes may play a role in the severity of signs and symptoms of Candida oral cavity infections in diabetic patients.

Introduction: Diabetes mellitus is a chronic metabolic disorder that induces elevated plasma glucose levels. Diabetic patients are more susceptible to infections, especially fungal infections. There is a direct relationship between increased blood glucose levels and the number of Candida hyphae in the oral mucosa. This study aimed to evaluate oral candidiasis and the different Candida species found in patients with and without diabetes mellitus. Methods: A search for studies on oral candidiasis and diabetes mellitus was carried out in the following databases: PubMed (MEDLINE, Cochrane Library), Web of Science (WoS) and Google Scholar. For dichotomous outcomes, the estimates of effects of an intervention were expressed as odds ratios (OR) using the Mantel-Haenszel (M-H) method with 95% confidence intervals. Results: 25 studies were included in this meta-analysis. Diabetes Mellitus patients tripled the probability of being infected by Candida species (OR:3.16, p<0.001). Likewise, Candida species infections were more likely in patients with poor glycemic control (OR:2.94, p<0.001) and with dentures (OR:2.22, p<0.001). In contrast, neither gender nor diabetes mellitus type of diabetes conditioned fungal infections (p>0.05). The most prevalent Candida species in both diabetics and controls were C. albicans and C. tropicalis. Diabetics had significantly fewer C. non-albicans species oral infections than non-diabetics (p=0.04). Conclusions: Diabetics are more prone to oral candidiasis, especially C. albicans infections.

  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.

Candida Colonisation

Oral candidiasis is an opportunistic infection caused primarily by Candida albicans. However, in recent years, species of non-albicans Candida have been implicated more frequently in mucosal infection. Candida species usually reside as commensal organisms and are part of normal oral microflora. Determining exactly how transformation from commensal to pathogen takes place and how it can be prevented is continuous challenge for clinical doctors. Candidal adherence to mucosal surfaces is considered as a critical initial step in the pathogenesis of oral candidiasis. Acrylic dentures, acting as reservoirs, play an important role in increasing the risk from Candida colonisation. Thus, this review discusses what is currently known about the adhesion of non-albicans Candida species of oral origin to buccal epithelial cells and denture acrylics.

Microbial Invasion

Candida albicans is the most common Candida species isolated from the oral cavity both in healthy and diseased. Candida albicans is a dimorphic fungus existing both in blastopore phase (yeast phase) and the hyphal or mycelial phase. Although these organisms typically colonize mucocutaneous surfaces, the latter can be portals of entry into deeper tissues when host defences are compromised. Denture stomatitis is a common form of oral candidiasis that manifests as a diffuse inflammation of the maxillary denture bearing areas & is associated with angular cheilitis. At least 70% of individuals with clinical signs of denture stomatitis exhibit fungal growth & these conditions most likely result from yeast colonization of the oral mucosa combined with Bacterial colonization. Candida species act as an endogenous infecting agent on tissue predisposed by chronic trauma to microbial invasion. At one time, oral fungal infections were rare findings in general dentist's office. They were more commonly seen in hospitalized and severely debilitated patients. However with enhanced medical and pharmaceutical technology, increasing numbers of ambulatory immunosuppressed individuals with oral fungal infections are seeking out general dentists for diagnosis and treatment of these lesions.

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: Oral candidiasis is caused by the mycotic activity of Candida albicans present in the oral cavity, and it is one of the most common opportunistic infections found in patients with Human Immunodeficiency Virus (HIV)/acquired immune deficiency syndrome (AIDS). The growing resistance and side effects to common antifungal drugs have promoted herbal essential oils as antifungal agents in recent years. In this study, essential oils (EO) of Rosmarinus officinalis (Lamiaceae) were examined for in vitro antifungal activ­ity against Candida species. Purpose: To evaluate the antifungal activity of essential oils of Rosmarinus officinalis (Lamiaceae) and nystatin using the microdilution technique by determining the minimum inhibitory concentration (MIC) and the minimum fungicidal concentration (MFC) of Candida spesies. Methods: This was an experimental laboratory study with a post-test-only design conducted in Dr. Soetomo General Academic Teaching Hospital, Surabaya. Forty isolates consisted of twenty isolates of Candida albicans and twenty isolates of Candida non-albicans were collected. The isolates were tested for antifungal activity using the microdilution on 96-well plates. Result: There was a significant difference from the results of the MIC concentration of rosemary essential 100% to 6.25% microdilution method between nystatin and rosemary essential oil (p < 0.05). Conclusion: The antifungal activity of rosemary essential oil was better than nystatin that the lowest MIC value, which was 6.25%, has been obtained the microdilution method. The minimum fungicidal concentration of rosemary essential oil was 25%, while the minimum fungicidal concentration nystatin was higher than 100%.

Background. A correlation has been noted between diabetes mellitus (DM) and changes in the oral cavity. The present study aimed to estimate, compare, and correlate serum and salivary glucose and IgA levels and salivary candidal carriage in diabetic and non-diabetic individuals. Methods. Eighty-eight subjects were categorized into three groups: group 1 (controlled DM; n=27), group 2 (uncontrolled DM; n=32) and group 3 (non-diabetics; n=29). Serum and salivary glucose levels were estimated by glucose oxidase/peroxidase method, serum and salivary IgA by a diagnostic kit, and candidal colonization by inoculating samples into Sabouraud dextrose agar plate. Statistical analyses were carried out by one-way ANOVA, post hoc Tukey tests, and Pearson’s correlation coefficient. Results. Significant elevation of serum IgA levels was observed in group 2 compared to group 3 and significant decreases in salivary IgA levels in groups 1 and 2. The candidal carriage was significantly higher in group 2 compared to group 3. Serum glucose and salivary IgA levels showed a significant correlation in group 1. There was a positive correlation between serum/ salivary glucose and serum/salivary IgA levels in group 2. In addition, there was a significant correlation between serum glucose and serum IgA levels in group 3. Conclusion. Saliva could be a potential, non-invasive diagnostic tool to estimate glucose levels. The evaluation of salivary components, like IgA, might be useful in diagnosing and managing oral manifestations in diabetic individuals. Elevated salivary glucose levels contribute to elevated candidal carriage, making individuals susceptible to oral candidiasis.
