Genetic divergence of Chikungunya viruses in India (1963-2006) with special reference to the 2005-2006 explosive epidemic.
TLDR
To examine relatedness of the Indian isolates of Chikungunya with Reunion Island isolates (RU), full-genome sequences of five CHIK virus isolates representative of different Indian states were determined and may help in understanding the association of the unique mutations with the explosive nature of the CHIK outbreak. Expand
Chikungunya Outbreaks Caused by African Genotype, India
TLDR
Phylogenic analysis based on partial sequences of NS4 and E1 genes showed that all earlier isolates (1963–1973) were Asian genotype, whereas the current and Yawat (2000) isolates were African genotype. Expand
Prevalence of anti‐hepatitis E virus antibodies in different Indian animal species
TLDR
The results document varied prevalence of anti‐HEV antibodies in different animal species from India and of inability of Indian pigs and goats to support replication of at least one human strain of HEV. Expand
A large outbreak of acute encephalitis with high fatality rate in children in Andhra Pradesh, India, in 2003, associated with Chandipura virus
TLDR
The findings suggest that this outbreak of acute encephalitis in Andhra Pradesh was associated with Chandipura virus, adding to the evidence suggesting that this virus should be considered as an important emerging pathogen. Expand
Thermal stability of hepatitis E virus.
TLDR
Although HEV was less stable than was HAV, some HEV would most likely survive the internal temperatures of rare-cooked meat. Expand
West Nile virus isolates from India: evidence for a distinct genetic lineage.
TLDR
This study documents circulation of WNV strains typical to India for 27 years and the introduction of lineage 1 strains during 1967-1968, indicating strongly that WNV should be classified into five genetic lineages, with Indian viruses constituting the distinct genetic lineage 5. Expand
Human and swine hepatitis E viruses from Western India belong to different genotypes.
TLDR
This study attempts to identify and partially characterize swine HEV from India and concludes that at least one human HEV strain could not infect pigs and circulates in Indian pigs. Expand
Chandipura virus: A major cause of acute encephalitis in children in North Telangana, Andhra Pradesh, India
TLDR
CHPV appears to be the major cause of acute viral encephalitis in children in endemic areas during earlymonsoon months during early monsoon months. Expand
Seroepidemiology of water-borne hepatitis in India and evidence for a third enterically-transmitted hepatitis agent.
TLDR
16 of the 17 epidemics of water-borne hepatitis in India were caused at least in part by serologically closely related hepatitis E viruses, however, one epidemic, in the Andaman Islands, and possibly a significant minority of cases in other epidemics, appears to have been caused by a previously unrecognized hepatitis agent. Expand
An outbreak of Chandipura virus encephalitis in the eastern districts of Gujarat state, India.
TLDR
Serologic and molecular assays documented the absence of Japanese encephalitis virus, West Nile virus, dengue virus, and paramyxoviruses in clinical samples, and the etiologic agent was Chandipura virus, which has become an important ennceitis-causing virus in India. Expand
