摘要 进行了芒果叶水提物对部分畜禽常见致病菌的体外抑制试验以及对10日龄鸡胚人工感染鸡新城疫病毒(NDV)的抑制试验。抑菌试验结果表明,芒果叶水提物对大肠杆菌、多杀性巴氏杆菌、鸡白痢沙门氏菌、猪丹毒杆菌43-6混43-8、金色葡萄球菌86003、鸭疫里默氏杆菌、链球菌等致病菌有良好的抑菌效果。抑制NDV增殖试验结果表明,NDV强毒组在48h时的鸡胚保护率为10.00%,2.500g/mL芒果叶生药+NDV组的鸡胚保护率为63.64%,两者差异显著(P<0.05);1.250g/mL+NDV组、0.625g/mL+NDV组、0.313g/mL+NDV组的鸡胚保护率分别为72.72%、70.00%、69.23%,与强毒组相比,差异极显著(P<0.01),可见芒果叶水提物对NDV增殖具有抑制作用。 An inhibiting-bacteria test was done about effects of extract of Mangifera indica L.leaf on some pathogenic bacteria of domestic animal and poultry by using paper method,and an inhibiting-NDV experiment by extract of M.indica leaf with chicken embryos infected artificially was carried out.The result of inhibiting-bacteria test showed that extract of M.indica leaf had strong inhibiting effect on Escherichia coli,Pasteurella multocida,Salmonella pullorum.Erysipelothrix rhusiopathiae,Staphylococcus aureus,Riemerella anatipestifer,Streptococci suis.The results of inhibiting-NDV showed that at 48 h the chicken embryos protective rate of NDV control group and 2.500 g/mL+NDV group were 10.00% and 63.64%,respectively.There was significant difference between groups (P<0.05).The protective rate of 1.250g/mL+NDV group,0.625g/mL+NDV group and 0.313g/mL+NDV group were 72.72%,70.00%,69.23%,respectively. There were extremely significant differences (P<0.01) compared with NDV control.It was suggested that extract of Mangifera indica leaf had inhibiting-NDV effects.
