Discussion on Bacterial oral swab study

There are many kinds of bacteria in the mouth of the human body. Нормальная флора полости рта играет определенную роль в поддержании нормальной и нормальной функции хозяина. Однако, Некоторые бактерии в нормальной флоре также могут вызывать заболевания, когда общая устойчивость хозяина и местный иммунитет низкие. Medical institutions use оральные мазки to study the distribution of normal bacteria in oral cavity patients.

Research methods:

1) With Medico sterile flocking оральный мазок smear gums and palate in patients with oral disease, and immediately separated from the sample on the blood plate, McKinsey plate at 37 ℃ 18 ~ 24dx, and then observe the colony morphology, pigment, hemolysis , Break down the characteristics of sugar, and Gram stain.

(2) The isolated Gram-positive cocci, Gram-negative bacilli for specific enzyme test and specific biochemical reactions.

(3) identification of gram positive bacilli and gram-negative cocci according to the characteristics of bacterial species. On the basis of the identification of the main fungal staining morphology, colony characteristics and sprouting, и т.д.

According to the sample analysis: Есть о 10 species of bacteria, 14 kinds of bacteria, but also a fungus, most of the living things in the oral normal resident, oral buccal separation of pathogenic bacteria in different age groups in the number of distribution, species Different
