Avian infectious laryngotracheitis virus (ILTV) possesses an alphaherpesvirus type D DNA genome of ca. 155 kbp. Completion of our previous sequence analyses (W. Fuchs and T. C. Mettenleiter, J. Gen. Virol. 77:2221-2229, 1996) of the right end of the unique long (UL) genome region revealed the presence of two adjacent, presumably ILTV-specific genes, which were named UL0 and UL[-1] because of th...

orf is a mucocutaneous disease that occurs when non-intact skin comes into contact with contaminated sheep saliva. the lesions may complicate to lymphangitis or secondary bacterial infection, but systemic complications such as erythema multiforme, maculopapular rash, and generalized lymphadenopathy are rare. in this paper, we present two cases of erythema multiforme following orf disease.

the study was conducted to determine the type, frequency and severity of gross, histopathologic changes, effect of route of infection and also, tissue tropism of serotype 793/b (4/91) infectious bronchitis virus. 20 day-old specific pathogen free chicks were inoculated intra-tracheally and intra-orally with 793/b serotype and lesions studied histopathologically at interval up to 10 days post-in...
