A total of 1246 faecal and tissue samples collected/received from 119 farms located in various states of India were processed for isolation of avian influenza viruses (AIV) during 2003-2004 as part of a program to monitor AIV infection in Indian poultry population. Avian influenza virus was isolated for the first time in India from poultry farms with(More)
H9N2 avian influenza viruses are endemic in domestic poultry in Asia and are grouped into three major sublineages represented by their prototype strains A/Duck/Hong Kong/Y280/97 (Y280-like), A/Quail/Hong Kong/G1/97 (G1-like) and A/Chicken/Korea/38349-p96323/96 (Korean-like). To understand the genetic relationship of Indian viruses, we determined the partial(More)
A nucleoprotein (NP) gene based reverse transcription polymerase chain reaction (npRT-PCR) assay was developed in our laboratory which could detect 35.09% of the experimental samples negative for virus isolation in first passage but positive by third passage. Reducing the reaction volume to 12.5 μl did not alter the test sensitivity and the results did not(More)
South Asia has experienced regular outbreaks of H5N1 avian influenza virus since its first detection in India and Pakistan in February, 2006. Till 2009, the outbreaks in this region were due to clade 2.2 H5N1 virus. In 2010, Nepal reported the first outbreak of clade 2.3.2 virus in South Asia. In February 2011, two outbreaks of H5N1 virus were reported in(More)
Outbreaks of highly pathogenic avian influenza (HPAI) H5N1 virus were reported for the first time in India during February 2006. Herein, we have sequenced and analyzed the PB2 genes of five influenza virus isolates obtained from three affected states (Gujarat, Madhya Pradesh and Maharashtra) in India during the outbreaks. In the phylogenetic analysis, the(More)
Outbreaks of H5N1 avian influenza virus were reported in 15 districts of West Bengal State in India in early 2008 and subsequent re-occurrence in 5 districts in December, 2008 to May, 2009. We have sequenced complete genome of 12 viruses isolated from early 2008 outbreak and from recurrent outbreak and determined the phylogenetic relationship between the(More)
This study reports the genetic characterization of highly pathogenic avian influenza (HPAI) virus (subtype H5N1) isolated from poultry in West Bengal, India. We analyzed all the eight genome segments of two viruses isolated from chickens in January 2010 to understand their genetic relationship with other Indian H5N1 isolates and possible connection between(More)
BACKGROUND The outcomes of surgically treated acetabular fractures are dependent on many factors. The purpose of this retrospective study is to evaluate these factors in a group of patients operated on by a single surgeon in one institute. METHODS One hundred and eighteen patients, treated surgically for their displaced acetabular fracture and who had(More)
In 2008, India experienced widespread outbreaks of H5N1 virus in West Bengal, Tripura, and Assam. The virus was detected in Kamrup district of Assam in November 2008 and subsequently spread to eight more districts. Two Jungle or Large billed crows (Corvus macrohynchos) were found dead in a hospital campus at about 8 km from the foci of initial detection of(More)
