The oral microbiota of humans and animals is made up of a wide variety of yeasts and bacteria, but microbiota of dogs is not totally described. Although such identification is an important step to establish the etiopathogenesis and adequate therapy for the periodontal disease The aim of this study was to evaluate and correlate oral alterations with the presence of yeasts in oral cavity of female dogs. After clinical evaluation samples from healthy and from dogs with oral diseases were obtained from three different oral sites by swabs, curettes, millimeter periodontal probes and HA membrane tip in cellulose ester. Yeast identification was performed through macroscopic and microscopic colony features and biochemical tests. Dental calculus was the most prevalent occurrence in the oral cavity of 59 females. However, the isolation of yeasts was significantly higher (p < 0.05) in animals suffering from halitosis. Eleven yeast species were identified, namely: Malassezia pachydermatis, Rhodotorula spp., Candida albicans, C. catenulata, C. famata, C. guilliermondii, C. parapsilosis, C. intermedia, Trichosporon asahii, T. mucoides and Cryptococcus albidus. It could be concluded that the yeasts are part of the microbiota from the different sites of the oral cavity of the female canines studied without causing any significant alterations except halitosis.
人和动物的口腔微生物群由各种各样的酵母和细菌组成，但犬类的微生物群尚未完全描述。虽然这种鉴定是确定牙周病病因和适当治疗的重要步骤，但本研究旨在评估和关联口腔变化与女性犬口腔中酵母的存在。在临床评估后，通过拭子、刮匙、毫米牙周探针和 HA 膜尖端在纤维素酯中从三个不同的口腔部位采集健康犬和患有口腔疾病犬的样本。通过宏观和微观菌落特征和生化试验进行酵母鉴定。牙结石是 59 只雌性口腔中最常见的发生，但口臭的动物中酵母的分离率显著更高（p<0.05）。鉴定出 11 种酵母，分别是：厚皮马拉色菌、红酵母属、白色念珠菌、假热带念珠菌、弗氏念珠菌、光滑念珠菌、近平滑念珠菌、中间念珠菌、近平滑假丝酵母、粘滑假丝酵母和白假丝酵母。可以得出结论，酵母是研究的雌性犬口腔不同部位微生物群的一部分，除口臭外，不会引起任何明显变化。
