Cherry virus A (CVA) is a graft-transmissible member of the genus Capillovirus that infects different stone fruits. Sweet cherry (Prunus avium L; family Rosaceae) is an important deciduous temperate fruit crop in the Western Himalayan region of India. In order to determine the health status of cherry plantations and the incidence of the virus in India, cherry orchards in the states of Jammu and Kashmir (J&K) and Himachal Pradesh (H.P.) were surveyed during the months of May and September 2009. The incidence of CVA was found to be 28 and 13% from J&K and H.P., respectively, by RT-PCR. In order to characterize the virus at the molecular level, the complete genome was amplified by RT-PCR using specific primers. The amplicon of about 7.4 kb was sequenced and was found to be 7,379 bp long, with sequence specificity to CVA. The genome organization was similar to that of isolates characterized earlier, coding for two ORFs, in which ORF 2 is nested in ORF1. The complete sequence was 81 and 84% similar to that of the type isolate at the nucleotide and amino acid level, respectively, with 5' and 3' UTRs of 54 and 299 nucleotides, respectively. This is the first report of the complete nucleotide sequence of cherry virus A infecting sweet cherry in India.

Background: The bird cherry-oat aphid, Rhopalosiphum padi, is a major pest of agriculture due to its ability to directly damage crops and transmit plant viruses. As industries move away from chemical pest control, there is interest in exploring new options to suppress the impact of this pest.
Results: We describe the production of a transinfected line of R.

Duck circovirus (DuCV) infected multiple breeds of ducks and was widespread in duck factories worldwide. Infected ducks exhibited feathering disorder, growth retardation and immunosuppression, which lead to secondary infection with other pathogens easily. But till now, there has been little research on the study of DuCV due to the absence of appropriate cultural measures.

Flavonoids are a group of plant secondary metabolites that have a number of health-promoting properties and have both preventive and therapeutic effects. Research confirms that flavonoids work, among others: antiviral and anticancer. Apigenin, luteolin, isorhamnetin, kaempferol, myricetin, quercetin, hesperetin, naringenin, epicatechin and genistein have documented antiviral activity.

Article Synopsis
- Newcastle disease virus (NDV) serves as a valuable model for studying viral mechanisms and is being utilized as a vector for vaccine development and cancer therapy.
- A reverse genetic system was created for the NDV Mukteswar strain, allowing for the insertion of the enhanced green fluorescent protein (EGFP) gene between the P and M genes to form a stable transcription unit that expresses exogenous genes over multiple generations.
- Through this system, a recombinant virus that co-expresses EGFP and cherry fluorescent protein (CFP) was developed, demonstrating efficient simultaneous expression of both proteins, though with slight differences in expression levels, and similar growth rates with mild virulence attenuation compared to the original strains.

Since 2023, an infectious upper respiratory tract disease has been persisted in outbreaks among in a flock of Cherry Valley ducks in Shandong Province, China. This outbreak was traced to avian metapneumovirus subtype C (aMPV-C), a significant pathogen associated with egg-drop and acute respiratory diseases in poultry. It is noteworthy that prior to this, aMPV-C infection had not been previously documented in Cherry Valley ducks within China.
