Occurrence of different subgroups of avian leukosis virus in finnish poultry

Avian Leukosis Virus

Ultrastructural studies of chick embryo cells morphological ly altered by strain MC29 avian leukosis virus revealed marked and characteristic differences from normal cells and cells al tered by infection with other avian tumor viruses. Such differ ences were manifest in part in the cytoplasm by high content of free ribosomes, poorly developed rough endoplasmic reticu lum, frequent fat droplets,...

Identifying different subgroups of rabies virus in Iran

Abstract: Background: Rabies has been reported in all provinces and cities of Iran, although there has been no molecular study regarding different groups and subgroups of rabies virus by phosphoprotein gene. In this study, firstly, 48 and then 85 recent rabies isolates recovered from cases reported throughout Iran identified the evolutionary origins by molecular method of phosphoprotein gene r...

Occurrence of avian leukosis virus subgroup J in commercial layer flocks in China.

Mortality from myeloid leukosis was observed in commercial layers from 12 farms in northern China. Affected chickens were extremely thin and dehydrated, bleeding occurred in feather follicles and claws, combs were pale and anaemic, phalanges were swollen, and many yellowish-white tumours were seen on the visceral surface of the sternum. Focal tumour cells, with spherical eosinophilic granules i...

Occupational exposure to poultry and prevalence of antibodies against Marek's disease virus and avian leukosis retroviruses.

OBJECTIVES To compare the prevalence of antibodies against Marek's disease herpes virus (MDV) and against avian leukosis viruses type C (ALV) in groups of workers exposed to poultry and in unexposed groups. METHODS Antibodies directed against avian viral proteins were detected by enzyme linked immunosorbent assay in 549 subjects. Exposure to chickens was high in two subgroups: farmers on inte...
