Well known and acute viral diseases result in serious after-effects, but these are often present as well after mild infections. Research is now being carried out on, amongst others, the putative role of viruses in neuro-psychiatric diseases which have been known to even lead to the development of anti-social behaviour in humans. Some of the data presented in this review concern: virokines as mediators of virus-host interaction; control of early viral distribution by natural antibodies; viral aetiology of fowl glioma; BAC-VAC - a new generation of DNA vaccines; effective drugs used against entero-viruses; the genetic relation of big liver and spleen (BLS) disease virus of hens to human hepatitis E virus; swine hepatitis E virus - a new pathogen; influenza A virus as a cause of sporadic-milk-drop syndrome in dairy cows; the adenovirus vector of p53 gene; molecular prosthesis restoring conformation and function of mutant p53 protein.
