Real-time PCR for differential quantification of CVI988 vaccine virus and virulent strains of Marek’s disease virus [PDF]
CVI988/Rispens vaccine, the 'gold standard' vaccine against Marek's disease in poultry, is not easily distinguishable from virulent strains of Marek's disease herpesvirus (MDV). Accurate differential measurement of CVI988 and virulent MDV is commercially important to confirm successful vaccination, to diagnose Marek's disease, and to investigate causes

Depression of Vaccinal Immunity to Marek’s Disease by Infection with Chicken Infectious Anemia Virus [PDF]
Marek’s disease (MD) has been occurring with increasing frequency in chickens in recent years. To our knowledge, however, there has been no report of the very virulent plus (vv+) MD virus (MDV) field isolate in China.

Induction of lymphomas by inoculation of Marek's disease virus-derived lymphoblastoid cell lines: prevention by CVI988 vaccination [PDF]
Lymphoblastoid cell lines 265(L) and 990(O) are monoclonal lymphomas, derived respectively from liver and ovarian tumours, generated in inbred P-line (MHC B(19)/B(19)) chickens infected with RB-1B strain of Marek's disease virus (MDV) and pRB-1B5 BAC clone respectively. These were inoculated into inbred, MDV-susceptible, P-line chickens by intra-venous

Pathology and Molecular Diagnosis of Marek's Disease Virus in Chickens in Nigeria. [PDF]
Marek’s disease caused by Marek’s disease virus (MDV) serotype 1 is an economically important neoplastic disease of poultry. Diagnosis of this disease is usually based on clinical signs, postmortem lesions, and diagnostic tests like cytology, histopathology, and molecular‐based methods.

High-fidelity long-read sequencing of an avian herpesvirus reveals extensive intrapopulation diversity in tandem repeat regions. [PDF]
Comparative genomic studies of Marek's disease virus (MDV) have suggested that attenuated and virulent strains share >98% sequence identity. However, these estimates fail to account for variation in regions of the MDV genome harboring tandem repeats.

Regulation of Wnt/β-catenin signaling by Marek’s disease virus in vitro and in vivo [PDF]
Marek’s disease virus (MDV) infection causes immunosuppression in the host, ultimately inducing tumor formation and causing significant economic losses to the poultry industry.

Genomic analysis of a Chinese MDV strain derived from vaccine strain CVI988 through recombination
Disease caused by Marek's disease virus (MDV), a highly oncogenic alpha-herpesvirus, is controlled mainly by vaccination. Since 1990s, CVI988 has been widely used as vaccine strain. However, as an attenuated live vaccine, CVI988 has the potential of virulence enhancement and the risk of recombination that should be considered.

Differences in Pathogenicity and Vaccine Resistance Discovered between Two Epidemic Strains of Marek’s Disease Virus in China [PDF]
Despite highly effective vaccines, Marek’s disease (MD) causes great economic loss to the poultry industry annually, largely due to the continuous emergence of new MD virus (MDV) strains.
