This study aimed to determine the occurrence of Candida spp. in the oral cavity of predominantly breastfed infants and in their mothers' mouths and breasts, as well as in the oral cavity of bottlefed infants and in non-lactating women. One hundred and sixty nine women and eighty-five milk-fed infants took part in this study and were divided into four groups: 1) infants predominantly on breastfeeding (n = 55) and their mothers (n = 55); 2) infants on bottlefeeding (n = 30); 3) non-lactating women on whom oral collections were performed (n = 80) and, 4) non-lactating women on whom breast collections were performed (n = 34). Oral and mammary swabs were cultured on Sabouraud agar dextrose with chloramphenicol. The Candida yeast strains found were isolated and identified through morphological and biochemical tests. Candida species were much less frequent in infants who were predominantly breastfed than in those who were bottlefed. Yeasts were much more frequent on the breasts of lactating women, with statistical difference in relation to the control group.

  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 species including Candida albicans, Candida krusei and Candida glabrata are opportunistic microorganisms that inhabit oral cavity. The objective of this study is to determine the effect of dental caries on Candida spp. biofilm-forming ability on nano- composite with the hypothesis that dental caries enhances the colonization of Candida spp. To assess Candida spp. colonisation in the oral cavity of the paediatric patient, samples were obtained from 30 subjects aged five to six years old from Kuantan, Pahang, Malaysia. The samples were collected from buccal mucosa, palate and tooth surfaces using sterile swabs. 10 mL of patient’s saliva suspension was also collected. Following that, the samples were inoculated on CHROMagar and incubated for 24 h at 37 ºC. Candida biofilm of caries isolate C. albicans (HNFC2), and C. albicans ATCC 32354 were developed on three different types of nano-composites. The study showed that no C. albicans was isolated from the caries-free oral cavity while 76% of children with caries possessed Candida spp. 65% of the yeasts were isolated from the tooth surface. Only 35% of the total isolates were obtained from soft tissues, including palatal and buccal mucosa. C. albicans is the most isolated Candida spp. with 82% and 67% of the yeast were obtained from the tooth surface and buccal mucosa, respectively. Besides, HNFC2 significantly colonised the nano- composites more than the ATCC (P < 0.05). In the comparison of the three types of nano- composites, nano-hybrid-based containing pre-polymerised filler (cB) exhibited the least C. albicans HNFC2 cells colonisation with 7.7 x 10³ cells mL-1. In contrast, the nano-composite that contained bulk-filled nanohybrid (cC) was the most colonised with 14.3 x 10³ cells mL-1. In conclusion, dental caries enhances the colonization of Candida spp. in children's oral cavity, and that caries isolate form more biofilm on nano-composites compared to the lab strain C. albicans.

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.

Abstract The aim of this study was to evaluate the frequency of Candida species between a non-hospitalized and a hospitalized population. For this purpose, samples of saliva were sampled through sterile swabs, moistened in peptone water and rubbed in the oral cavity of 140 individuals, from which, 70 were hospitalized patients from the Medical Clinic of a Teaching Hospital and the other 70 were non-hospitalized subjects. All saliva samples were plated in Sabouraud Dextrose agar added with Chloramphenicol and incubated at 36 °C for 48 hours. The morphology identification was performed through macroscopic and microscopic characterization, the CHROMagar Candida medium and the VITEK® system Yeast Biochemical Card (bio Mérieux SA, France). The results showed a colonization of Candida spp. in 85.7% the hospitalized individuals, where the species found were C. albicans (60%), C. tropicalis (23.4%), C. krusei (3.3%) and Candida spp. (13.3%). In the non-hospitalized individuals the colonization by Candida spp was 47.1%, and the species found were: C. albicans (45.5%), C.krusei (9.1%), C. guilliermondii (9.1% %), C. tropicalis (3.0%), C. famata (3.0%) and Candida spp. (30.3%). In spite of their presence in oral cavity in both groups, Candida spp. was more frequently isolated in hospitalized individuals, who were 6.73 times more likely to have this fungus in the oral cavity and were 3.88 times more likely to have Candida albicans.
