Abstract

Background and Aims: Candida albicans is the most prevalent opportunistic fungal species in the oral cavity. To date, several studies have been investigated the various factors associated with oral candidiasis. On the other hand, it has been proven that blood types antigens lead to some infectious factors. This study aimed to evaluate Candida albicans colonies in the saliva of dentistry students based on their blood type to detect a relationship between blood group and incidence of oral candidiasis. Materials and Methods: In this descriptive cross-sectional study, 200 dentistry students were selected by a simple sampling method, including 100 individuals with blood type O and 100 with other blood types. The unstimulated salivary samples of all the participants were collected by spitting, cultured on Sabouraud medium, and then the isolated Candida albicans colonies were enumerated and recorded. Results: In the present study, samples comprised 77 males and 123 females, of whom 15.5% (31 individuals) carried colony-forming units > 40. The mean of Candida albicans colonies in the individuals' saliva with blood type O was 21.55, and it was 10.68 in the other groups. Besides, the differences were statistically significant (p = 0.024). There was no significant difference in Candida albicans colony count between O positive and O negative blood groups. Conclusions: The result of this study showed a significant relationship between the number of Candida albicans colonies of saliva and the individual’s blood type.
牙科学生唾液白色念珠菌菌落计数与血型抗原的关系
背景与目的:白色念珠菌是口腔中最常见的机会性真菌。迄今为止,已有几项研究调查了与口腔念珠菌病相关的各种因素。另一方面,已经证明血型抗原会导致一些感染因素。本研究旨在基于血型对牙科学生唾液中的白色念珠菌菌落进行检测,以探讨血型与口腔念珠菌病发病率的关系。材料与方法:采用简单抽样的方法,选取200名牙科专业学生进行描述性横断面研究,其中O型血100人,其他血型100人。所有受试者均采用吐痰法收集未受刺激的唾液样本,在Sabouraud培养基上培养,并对分离的白色念珠菌菌落进行计数和记录。结果:本研究共有雄虫77只,雌虫123只,其中15.5%(31只)携带> 40个菌落形成单位。O型血人群唾液中白色念珠菌菌落数平均值为21.55个,其他组为10.68个。差异有统计学意义(p = 0.024)。O阳性和O阴性血型间白色念珠菌菌落计数无显著差异。结论:本研究结果显示唾液中白色念珠菌菌落数量与个体血型之间存在显著关系。
