摘　　要：为研究大蒜、生姜、辣椒和韭菜的榨取原汁对金黄色葡萄球菌、大肠埃希氏菌和铜绿假单胞菌这3种常见致病菌的抑制作用,采用滤纸片法,经实验培养后可知,大蒜原汁在这3种常见致病菌上的抑菌圈直径分别为4.40 cm、3.35 cm和2.60 cm,生姜原汁在这3种常见致病菌上的抑菌圈直径均≤1.60 cm,韭菜原汁在这3种常见致病上的抑菌圈直径分别为3.00 cm、2.10 cm和2.60 cm,辣椒原汁在这3种常见致病菌上的抑菌圈直径分别为3.20 cm、2.10 cm和1.85 cm。通过对比培养基上抑菌圈的直径大小可知大蒜、辣椒和韭菜原汁对这3种致病菌均有抑制作用,而生姜原汁对这3种致病菌没有抑制作用。这4种天然抑菌植物原汁中大蒜原汁对金黄色葡萄球菌、大肠埃希氏菌和铜绿假单胞菌的抑制作用最大。3种致病菌中生长受抑制最大的是金黄色葡萄球菌。For the study of extract of garlic,ginger,pepper and leek juice on Staphylococcus aureus,Escherichia coli,Pseudomonas aeruginosa and the three kinds of common pathogens inhibition,using the filter method,after the experimental training,the garlic juice on the three kinds of common pathogens of bacteriostatic circle diameter 4.40 cm,3.35 cm and 2.60 cm,the diameters of the inhibition zones of ginger juice on the three common pathogenic bacteria were all≤1.60 cm,and the diameters of the inhibition zones of leek juice on the three common pathogenic bacteria were 3.00 cm,2.10 cm and 2.60 cm,respectively.The diameters of inhibition zones on the three common pathogens were 3.20cm,2.10 cm and 1.85 cm,respectively.By comparing the diameters of bacteriostatic circles on the culture medium,we can see that garlic,pepper and leek juice have inhibitory effects on these three kinds of pathogenic bacteria,while ginger juice has no inhibitory effect on these three kinds of pathogenic bacteria.Among the four natural antibacterial plant juices,garlic juice had the greatest inhibitory effect on Staphylococcus aureus,Escherichia coli and Pseudomonas aeruginosa.Staphylococcus aureus was the most inhibited among the three pathogenic bacteria.
