Pus samples of 30 patients with closed dentoalveolar abscesses who had not received antimicrobial therapy for at last two months were screened for the presence of beta-lactamase-producing anaerobic bacteria. From these 30 pus samples, a total of 112 bacterial strains were isolated; 83 of them were strict anaerobes and 29 were aerobes. beta-lactamases activity of the selected anaerobic bacteria was tested after identification of the isolates and was detected in 5 of the total 83 (6%) strict anaerobic isolates, whereas these 5 strains were isolated in 4 of the 30 (13.3%) pus samples. The species with beta-lactamase activity were in the Prevotella intermedia (4 from 14 isolates) and the Fusobacterium nucleatum (1 from 9 isolates) groups. None of the gram-positive and the other gram-negative anaerobic strains were beta-lactamase positive.
对30例近两个月未接受抗菌治疗的闭合性牙槽脓肿患者的脓液样本进行筛选，以检测产β-内酰胺酶厌氧菌的存在情况。从这30份脓液样本中，共分离出112株细菌菌株；其中83株为严格厌氧菌，29株为需氧菌。对分离出的厌氧菌进行鉴定后，检测其β-内酰胺酶活性，在总共83株严格厌氧菌分离株中有5株（6%）检测到β-内酰胺酶活性，而这5株菌株来自30份脓液样本中的4份（13.3%）。具有β-内酰胺酶活性的菌种属于中间普氏菌（14株分离株中有4株）和具核梭杆菌（9株分离株中有1株）组。革兰氏阳性和其他革兰氏阴性厌氧菌株均无β-内酰胺酶阳性。
