Newcastle disease virus (NDV), an avian paramyxovirus, induces apoptosis in chicken embryo fibroblast (CEF) cells. In the present investigation, the ability of haemagglutinin-neuraminidase (HN) protein of NDV to cause apoptosis in CEF cells was examined. The results revealed that cells expressing the HN protein demonstrated decreased DNA content,(More)
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(More)
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. The sequence analysis revealed that the PPRV(More)
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(More)
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(More)
AIM The aim was to clone and sequence hfq gene of Salmonella Typhimurium strain PM-45 and compare its sequence with hfq gene of other serovar of Salmonella. MATERIALS AND METHODS Salmonella Typhimurium strain PM-45 was procured from the G. B. Pant University of Agriculture and Technology, Pantnagar, India. The genomic DNA was isolated from Salmonella(More)
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(More)
Certain matrix metalloproteinases like MMP-11 (Stromelysin-3) and MMP-7 (Matrilysin) are reported to be highly expressed in breast cancer, so they may act as marker enzymes for breast cancer progression. Hyperimmune sera were raised against heterologously expressed recombinant canine MMP-11 in rabbits and guinea pigs to standardize sandwich ELISA (sELISA)(More)
