Development of a multiplexed Luminex assay for simultaneous detection of enteric viruses in cattle.

Viral and bacterial gastroenteritis and diarrhea have long been a problem in livestock with devastating effects on animal health and production causing a heavy financial burden on producers. Therefore, the bead-based multiplex detection assay was created for simultaneous detection of three livestock viral diarrheic agents . bovine rotavirus (BRV), bovine coronavirus (BCoV) and bluetongue virus (BTV).

Development of real-time RT-PCR systems for detection and quantitation of bovine enteric viral pathogens.

The enteric viruses in animals are responsible for severe and devastating losses to the livestock owners with a profound negative impact on animal, health, welfare, and productivity. These viruses are usually transmitted via the feco-oral route and primarily infect the digestive tract of the humans, bovines and different mammals as well as birds. Some of the important enteric viruses in ruminants are: Rotavirus A (RVA), Peste des petits virus (PPRV), Norovirus (NV), Bovine corona virus (BoCV) and Bluetongue virus (BTV).

Genetic Analysis of HIBM Myopathy-Specific GNE V727M Hotspot Mutation Identifies a Novel COL6A3 Allied Gene Signature That Is Also Deregulated in Multiple Neuromuscular Diseases and Myopathies.

The GNE-associated V727M mutation is one of the most prevalent ethnic founder mutations in the Asian HIBM cohort; however, its role in inducing disease phenotype remains largely elusive. In this study, the function of this hotspot mutation was profoundly investigated. For this, V727M mutation-specific altered expression profile and potential networks were explored.

Dissecting role of founder mutation p.V727M in GNE in Indian HIBM cohort.

GNE gene-specific c.2179G>A(p.V727M) is a key alteration reported in patients with hereditary inclusion body myopathy (HIBM) and represents an ethnic founder mutation in the Indian cohort.

Challenges and Advances in Molecular Diagnosis of Myopathies and Dystrophies in Perspective of Their Use in Developing Countries: Past, Present, and Future.

Background: Proper diagnosis is the first and most critical step for effective identification and treatment of myopathy and dystrophy disorders. Although various histochemical and biochemical studies have paved the way for efficient testing of these disorders, they are insufficient for accurate diagnosis. To overcome this, the diagnostic procedure has now shifted more toward the "genetic first approach," with the remarkable role played by various genetic and molecular techniques.

Real-time monitoring of air pollutants in seven cities of North India during crop residue burning and their relationship with meteorology and transboundary movement of air.

Air pollutants emissions due to the burning of crop residues could adversely affect human health, environment, and climate. Hence, a multicity campaign was conducted during crop residue burning period in Indo Gangetic Plains (IGP) to study the impact on ambient air quality. Seventeen air pollutants along with five meteorological parameters, were measured using state of the art continuous air quality monitors.

Emergence of sulfadoxine-pyrimethamine resistance in Indian isolates of Plasmodium falciparum in the last two decades.

Genotyping the sulfadoxine-pyrimethamine (SP) genes will help in identifying the genes under drug selection and the emergence of resistance in dhfr and dhps genes. India is an important hotspot for studying malaria due to the immense climatic diversity prevalent in the country. The central and eastern parts of the country are most vulnerable sites where malaria cases are reported throughout the year.

Sequence and topological characterization of Toll-like receptor 8 gene of Indian riverine buffalo (Bubalus bubalis).

In this study, buffalo (Bubalus bubalis) Toll-like receptor 8 (TLR8) gene has been characterized by sequence analysis and detecting polymorphism. Complete ORF of buffalo TLR8 gene was amplified using the RNA isolated from spleen tissue, which was found to be 3,102 nucleotides long encoding a 1,033 amino acid protein. Buffalo TLR8 had 10 nucleotide changes as compared to other livestock species resulting in six unique amino acid changes, four of them lying within leucine-rich repeat (LRR) domains.

Development of an in vitro system to measure the sensitivity to the antiviral Mx protein of fish viruses.

Mx is a structural protein, induced by type I interferon (IFN), with direct antiviral properties. In fish the inherent contribution of Mx protein to viral protection is unknown. The transgenic Chinook salmon embryonic (CHSE)-TOF cell line was genetically modified to express the rainbow trout Mx (rbtMx1) protein under the control of the tetracycline derivative, doxycycline (DOX).

Expression of interferon and interferon--induced genes in Atlantic salmon Salmo salar cell lines SHK-1 and TO following infection with Salmon AlphaVirus SAV.

Salmon AlphaVirus (SAV) is the aetiological agent of Salmon Pancreas Disease (SPD), a serious disease in farmed Atlantic salmon. Currently there is no available information on the ability of this virus to stimulate or suppress aspects of innate immunity in host cells. Two different Atlantic salmon cell lines (SHK-1 and TO), both derived from head kidney leucocytes, were infected with SAV and the kinetics and magnitude of gene expression were studied by real-time quantitative PCR.

Infectious pancreatic necrosis virus suppresses type I interferon signalling in rainbow trout gonad cell line but not in Atlantic salmon macrophages.

RTG-P1 cells are a rainbow trout fibroblastic cell line permanently transfected with the luciferase gene under the control of the Mx promoter. On exposure to interferon (IFN) or IFN inducing agents, the cells produce luciferase. IPNV did not induce luciferase production up to 24h post-infection but did not suppress constitutive luciferase production.
