We selected mecA gene and femA factor asβ-lactam antibiotic-resistant genes, ermA, ermC, msrAgene as macrolides-lincosamids antibiotic-resistant genes, norA, grlA, gyrA, gene as Quinolonesantibiotic-resistant genes, and tetM gene as Tetracycline antibiotic-resistant genes on the basis of the latestresearch. We designed primers with GenBank enunciable gene sequence, cloned the drug resistantgenes, and sequenced these genes.

The pathogenic bacterium of prepartum and intrapartum infectious pneumonia mostly were G- bacilli,the pathogenic bacterium of postpartum infectious pneumonia mostly were G- bacilli and staphylococcus aureus.6.The drug resistant rates of G- bacteria to penicillins,cephalosporins,and monocyclicβ-lactam antibiotic were high,However,their compound of addingβ-lactamase inhibitor agents was relatively low resistance,and all G- bacteria were sensitive to carbapenem antibiotics.

产前及产时感染性肺炎的病原菌以G-杆菌多见，而产后感染性肺炎的病原菌主要为G-杆菌和金葡菌。6.G-菌对青霉素类、头孢菌素类及单环类的β内酰胺类抗生素耐药率高，但对其添加β内酰胺酶抑制剂的复合制剂耐药率较低，对碳青霉烯类抗生素均敏感；金葡菌对苯唑西林耐药率低，对万古霉素均敏感。7。
