Specific IgM Antibody in Serum of Patients with Herpes Zoster Infections

Specific IgM varicella-zoster antibody was detected in “convalescent” sera from 20 out of 40 patients (50%) with herpes zoster infections. Since these were not primary infections with varicella-zoster virus, it seems that detection of IgM antibody specific for a particular virus may not differentiate a primary infection from secondary infections with that virus.     

Herpes Zoster and Multiple Sclerosis

No significant difference was found between 50 consecutive patients with multiple sclerosis and matched controls in respect of previous infection with rubella or measles and chicken-pox, or of previous vaccination and immunizing injections. Significantly more patients had a past history of herpes zoster compared with the controls.     

网状内皮增生病病毒感染SPF鸡对疫苗免疫反应的抑制作用

我国鸡群中网状内皮增生病病毒(REV)感染已相当普遍,但对其造成的实际危害却不太清楚.本研究结果表明,1日龄SPF鸡感染REV会显著抑制对新城疫病毒(NDV)和禽流感病毒(AIV,H5和H9)疫苗的免疫反应.1周龄用相应灭活疫苗免疫后3周、4周和5周,REV感染组对不同病毒疫苗免疫后的HI效价显著低于对照组.高剂量REV感染组的抑制作用大于低剂量感染组,但统计学差异不显著.REV感染可造成中枢免疫器官萎缩,REV感染组的胸腺、法氏囊与体重比显著低于对照组.本研究证明了,REV早期感染会干扰鸡群对NDV、AIV的免疫效果,特别是会严重干扰对AIV疫苗的免疫效果.
