Three newly identified Immediate Early Genes of Bovine herpesvirus 1 lack the characteristic Octamer binding motif- 1.

Only three immediate early genes (IE) BICP0, BICP4 and BICP22 of Bovine herpesvirus 1 (BoHV-1) are known. These genes are expressed coordinately and their promoters are well characterized. We provide evidence for expression of three additional IE genes of BoHV-1 i.

Detection of Peste Des Petits Ruminants Virus (PPRV) Genome from Nasal Swabs of Dogs.

Peste des petits ruminants virus (PPRV) one of the most important viruses of small ruminants has a restricted host range. We report here the presence of PPRV virus in the nasal swabs of 3 out of 12 dogs in a routine microarray screening. The presence of PPRV sequence was further confirmed by PCR and sequencing.

Viral diagnosis in Indian livestock using customized microarray chips.

Viral diagnosis in Indian livestock using customized microarray chips is gaining momentum in recent years. Hence, it is possible to design customized microarray chip for viruses infecting livestock in India. Customized microarray chips identified Bovine herpes virus-1 (BHV-1), Canine Adeno Virus-1 (CAV-1), and Canine Parvo Virus-2 (CPV-2) in clinical samples.

Bovine Herpes Virus 1 Major Immediate Early Transcription Unit 1 (IETU-1) Uses Alternative Promoters to Transcribe BICP0 and BICP4 Transcripts.

Immediate early (IE) genes are transcribed immediately after infection in BHV1 from two different immediate early transcription units. It is reported that the immediate early transcription unit I (IE TU1) of Bovine herpesvirus 1 (BHV1) transcribes two proteins BICP0 and BICP4 from a single promoter by alternative splicing but with identical 5'UTR. We found that the transcripts of BICP0 and BICP4 have different 5'UTRs.

Animal Viruses Probe dataset (AVPDS) for microarray-based diagnosis and identification of viruses.

AVPDS (Animal Viruses Probe dataset) is a dataset of virus-specific and conserve oligonucleotides for identification and diagnosis of viruses infecting animals. The current dataset contain 20,619 virus specific probes for 833 viruses and their subtypes and 3,988 conserved probes for 146 viral genera. Dataset of virus specific probe has been divided into two fields namely virus name and probe sequence.

Microarray chip based identification of a mixed infection of bovine herpesvirus 1 and bovine viral diarrhea 2 from Indian cattle.

Bovine herpesvirus 1 (BHV1) and bovine viral diarrhea virus 2 (BVD2) are endemic in India although no mixed infection with these viruses has been reported from India. We report first mixed infection of these viruses in cattle during routine screening with a microarray chip. 62 of the 69 probes of BHV1 and 42 of the 57 BVD2 probes in the chip gave positive signals for the virus.

Isolation of Newcastle disease virus from a non-avian host (sheep) and its implications.

Newcastle disease virus (NDV) is an avian virus that has not been isolated from naturally infected non-avian and non-human hosts except for one report in which it was isolated from cattle in 1952. We report here for the first time the isolation and identification of NDV from sheep and suggest that this virus be included in the screening of viruses from non-avian hosts.
