Abstract

A total of 967 isolates of Gram-positive and Gram-negative bacteria were tested for the production of beta-lactamase by the PADAC test strip, and the results were compared with acidometric, disk diffusion and antibiotic dilution procedures. All the penicillinase producing strains of gonococci (23) and Haemophilus influenzae (36) gave positive results with PAD AC, but the 361 isolates of Staphylococcus aureus and S. epidermidis remained negative. All of the 547 strains of penicillin sensitive strains of gonococci, Haemophilus and staphylococci were negative with PADAC test.

PADAC试纸条快速检测内酰胺酶
采用PADAC试纸条对967株革兰氏阳性菌和革兰氏阴性菌进行β -内酰胺酶产酶试验,并与酸度法、纸片扩散法和抗生素稀释法进行比较。所有产青霉酶的淋球菌(23株)和流感嗜血杆菌(36株)的PAD AC检测结果均为阳性,但361株金黄色葡萄球菌和表皮葡萄球菌检测结果为阴性。547株淋球菌、嗜血杆菌和葡萄球菌青霉素敏感菌株PADAC试验均为阴性。
