In Vitro Bactericidal Activity Of Jinghua Weikang Capsule (Ei Dagger Es +/- E Integral Integral A(0)Center Dot E Integral A) And Its Individual Herb Chenopodium Ambrosioides L. Against Antibiotic-Resistant Helicobacter Pylori

To investigate the bactericidal effects of Jinghua Weikang Capsule (ei dagger eS +/- e integral integral a(0)center dot e integral a) and its major component Chenopodium ambrosioides L. on antibiotic-resistant Helicobacter pylori.Four clinical antibiotic-resistant H. pylori strains were isolated and incubated in liquid medium containing Jinghua Weikang Capsule or Chenopodium ambrosioides L. By means of time-kill curve method, the average colony counts and bactericidal rate were calculated at time points of 0, 4, 8 and 24 h after the incubation and the time-kill curves were charted.Both Jinghua Weikang Capsule and Chenopodium ambrosioides L. at a concentration of 0.64 g/L showed obvious bactericidal effect against antibiotic-resistant H. pylori after 4 h of incubation.Jinghua Weikang Capsule and Chenopodium ambrosioides L. are considered to be active against antibiotic-resistant H. pylori in vitro.
