Wildlife is known to be a source of high-impact pathogens affecting people. However, the distribution, genetic diversity, and zoonotic potential of , , and in wildlife are poorly understood. Here, we conducted the first molecular epidemiological investigation of these three pathogens in wildlife in Zhejiang and Shanghai, China. Genomic DNAs were derived from 182 individual fecal samples from wildlife and then subjected to a nested polymerase chain reaction-based sequencing approach for detection and characterization. Altogether, 3 (1.6%), 21 (11.5%), and 48 (26.4%) specimens tested positive for species, , and , respectively. Sequence analyses revealed five known (BEB6, D, MJ13, SC02, and type IV) and two novel (designated SH_ch1 and SH_deer1) genotypes of . Phylogenetically, novel genotype SH_deer1 fell into group 6, and the other genotypes were assigned to group 1 with zoonotic potential. Three novel genotypes ( avian genotype V-like and -like 1 and 2) were identified, -like 1 and 2 formed a clade that was distinct from species. The genetic distinctiveness of these two novel genotypes suggests that they represent a new species of Zoonotic assemblage A ( = 36) and host-adapted assemblages C ( = 1) and E ( = 7) of were characterized. The overall results suggest that wildlife act as host reservoirs carrying zoonotic and , potentially enabling transmission from wildlife to humans and other animals.

Background: Nipah virus is a pathogenic virus of ruinous zoonotic potential with inflated rate of mortality in humans.

Methods: Considering the emerging threat of this pandemic virus, the present investigation amid to design vaccine by using the bioinformatics tools such as host and virus codon usage analysis, CD8+ peptide prediction, immunogenicity/allergenicity/toxicity, MHC-I allele binding prediction and subsequent population coverage and MHC-I-peptide docking analysis.

Results: In this study (conducted in 2022 at School of Biotechnology, Katra, India), a set of 11 peptides of the structural proteins of Nipah Virus were predicted and recognized by the set of MHC-I alleles that are expressed in 92% of the global human population.

Global pandemic has emphasized the needs for advanced pathogen diagnosis in dealing with newly emerged infectious threats, including the Langya henipavirus (LayV). LayV, as an emerging zoonotic pathogen, has potential to cause pandemic, but lacks of rapid diagnostic tools, particularly at point-of-care level. Here, we leveraged the merits of CRISPR-Cas12a biosensing and established a highly sensitive LayV detection method.

Rabies is a zoonotic viral disease transmitted mainly by bites of infected animals, especially dogs, which are responsible for 99% of human cases. Despite being preventable, it remains a neglected disease in low-income countries, with approximately 60,000 deaths per year, mostly concentrated in Africa and Asia. The real worldwide burden of rabies is probably underestimated, as death-reporting systems are inadequate and active surveillance is limited.

Fasciolosis, caused by the liver flukes and , is a zoonotic parasitic disease associated with substantial economic losses in livestock. The transforming growth factor-beta signalling pathway is implicated in developmental processes and biological functions throughout the animal kingdom, including the spp. It may also mediate host-helminth interactions during infection.

Worldwide, a variety of mycobacterial species have been associated with skin lesions in dogs and cats. Lesions may result from systemic dissemination or local cutaneous inoculation. Only infections with Mycobacterium tuberculosis complex organisms have the potential to be transmitted from companion animals to humans, but even then, zoonotic risk is considered low.
