摘要
以猪传染性胃肠炎(TGE)弱毒疫苗经与胃肠道疾病相关的足阳明胃经6个穴位和督脉经后海穴位共7个穴位的穴位免疫筛选试验,证明后海穴接种为3/3保护,是首选的接种穴位。以后海穴取代TGE苗原鼻内途径的第二次接种,免疫4头妊娠母猪,对所产仔猪的保护数为37/41。以小剂量0.1ml及0.2ml后海穴接种3日龄仔猪,保护率分别为60.53%及100%,而口服0.1ml只保护6.67%。针刺1.5cm及3.0cm深度注苗的穴位刺激参数试验均获全保护。针刺点旁离穴位0.5cm及1.0cm分别获100%及75%保护,而同时设的肌肉途径接种组只获25%保护,首次证明后海穴具有相对免疫特异性。TGE灭活苗后海穴一次接种被动免疫保护率为77.45%,主动免疫为95%。猪流行性腹泻(PED)灭活苗被动免疫保护率为97.03%,主动免疫试验0.1ml及0.5ml的保护率分别为77.78%m和85%。TGE、PED二联灭活苗的被动免疫试验的总保护率TGE为87.9%PED为82.4%。注苗后攻毒前TGE与PED的中和抗体价均为1∶128,攻毒后7~10天中和抗体价均为1∶256,主动免疫试验的总保护率:TGE为100%,PED为97?
points of the stomach channel of Foot Yang Ming and Hou Hai point of Du Mai derian associated with stomach and intestines diseases were inoculated with attenuated transmissible gastroenteritis(TGE)virus.The Hou Hai point was selected to be the best vaccination cupture point with 3/3 protection.Then 4 pregnantwere inoculated at Hou Hai point instead of primary nasal inoculation at the second vaccina sows tion,and protective for piglets was 37/41 with 0 1ml dose,23/38 3 day old piglets were pratected by Hou Hai point route,however,only 1/15 by oral route.Further more,both injection depths of 1 5 cm and 3 0 cm yield 100% protection.Inoculating at 0 5 cm and 1 0 cm away from Hou Hai point display similar protection,the former 4/4 and the later 3/4.On the Contrast,mere 1/4 piglets were protected by intramuscular inoculation route.These results proved that Hou Hai point characterized with a relative speciality on immunity to TGE.The passive and active immune protection for piglets to TGE and porcine epidemic diarrhoea(PED)by Hou Hai point inoculating with inactive vaccine were also evalualed.The inactive TGE vaccine induced 77 45% passive immune protection and 95% active protection.The inactive PED vaccine induced 97 03% passive protection and 77 78% to 85% active protection.The Combinated inactive TGE and PED vaccine showed passive protection 87 98% to TGE and 82 4% to PED,active protection 100% to TGE and 97% to PED.
