Replication of Gross Leukemia Virus in Long-Term Cultures of Rat Thymomas: Bioassays and Electron Microscopy1

Replication of gross leukemia virus in long-term cultures of rat thymomas: bioassays and electron microscopy.

Two cultures of leukemic cells were established from Gross virus-induced rat thymomas and grown in vitro for 29 and 36 months. A constant and predictable virus yield was obtained that resulted in 100% induction of leukemia when cell-free materials from these cultures were assayed in susceptible animals. Electron microscopic studies of these cultures confirmed the abundance of virus and permitte...

Effects of Sodium Valproate on the Replication of Herpes Simplex Virus Type 1: An in Vitro Study

Background: Sodium valproate, an anticonvulsant drug, is reported to stimulate Human Immunodeficiency Virus type 1 and Human cytomegalovirus replication. Since epileptic patients undergoing sodium valproate therapy may suffer from various virus infections, the effect of this drug on replication of viruses especially those affecting neuronal tissues such as Herpes simplex virus type 1 is worthy ...

Studies on the replication of African Horse Sickness Virus in two different cell line cultures

Replication Characteristics of Herpes Simplex Virus Type-1 (HSV-1) Recombinants in 3 Types of Tissue Cultures

A complication in the analysis of the role of ICP34.5 gene in the herpes simplex virus type-1 (HSV-1) lifecycle is the presence of overlapping antisense gene, open reading frame P (ORF P), which is also deleted in HSV-1 ICP34.5 negative mutants. A HSV-1 wild type strain (17+) ICP34.5/ORF P deletion mutant (1716) is totally avirulent in animal models and impaired in a number of in vitro function...

Replication Kinetic of Infectious Laryngotracheitis Virus in Embryonic Chicken Neural Stem Cell

Background and Aims: Infectious laryngotracheitis virus (ILTV) infection causes a highly contagious respiratory disease in poultry leads to significant economic losses in the poultry industry. The genomic and antigenic characteristics between virulent and vaccine strains of ILTV are very similar. The ability of embryonated chicken neural stem (CNS) cell for differential diagnosis of ILTV strain...
