Emergence of novel Porcine circovirus 2 genotypes in Southern India.

A total of 200 samples from Porcine circovirus 2 suspected (n = 112) and healthy (n = 88) swine populations collected from different districts of Tamil Nadu, south India were used in this study. The samples comprising of serum (n = 124), swabs from natural orifices (n = 52), and postmortem tissues (n = 24). All the samples were processed and subjected to the screening and detection of the PCV2 genome by a specific PCR assay.

Complete nucleotide sequence analysis of the oncogene "Meq" from serotype 1 Marek's disease virus isolates from India.

1. A study was undertaken to characterise the oncogene Meq at the molecular level for three serotype 1 Marek's disease virus (MDV) field isolates from vaccinated poultry flocks which had encountered a Marek's disease outbreak in the southern part of India. The isolates were named Ind/TN/11/01, Ind/KA/12/02 and Ind/TN/12/03.

Pathotyping of recent Indian field isolates of Marek's disease virus serotype 1.

A study was undertaken to assess the virulence of Marek's disease virus (MDV) serotype 1 field isolates obtained from poultry flocks of southern part of India. Five representative MDV serotype 1 strains were isolated from eighty-six blood samples collected from fifteen farms. Three out of five isolates which were free from avian leukosis virus (ALV) and reticuloendotheliosis virus (REV) were adapted in chicken embryo fibroblast (CEF) culture and designated as Ind/TN/11/01, Ind/KA/12/02 and Ind/TN/12/03.
