Identification of Human Norovirus GII.3 Blockade Antibody Epitopes.

Human noroviruses are a common pathogen causing acute gastroenteritis worldwide. Among all norovirus genotypes, GII.3 is particularly prevalent in the pediatric population.

Yeast-produced RBD-based recombinant protein vaccines elicit broadly neutralizing antibodies and durable protective immunity against SARS-CoV-2 infection.

Massive production of efficacious SARS-CoV-2 vaccines is essential for controlling the ongoing COVID-19 pandemic. We report here the preclinical development of yeast-produced receptor-binding domain (RBD)-based recombinant protein SARS-CoV-2 vaccines. We found that monomeric RBD of SARS-CoV-2 could be efficiently produced as a secreted protein from transformed Pichia pastoris (P.

Identification of a blockade epitope of human norovirus GII.17.

Human noroviruses are the dominant causative agent of acute viral gastroenteritis worldwide. During the winter of 2014-2015, genotype GII.17 cluster IIIb strains emerged as the leading cause of norovirus infection in Asia and later spread to other parts of the world.

Identification of a Novel Ichthyic Parvovirus in Marine Species in Hainan Island, China.

Parvoviruses are a diverse group of viruses that are capable of infecting a wide range of animals. In this study, we report the discovery of a novel parvovirus, tilapia parvovirus HMU-HKU, in the fecal samples of crocodiles and intestines of tilapia in Hainan Province, China. The novel parvovirus was firstly identified from crocodiles fed with tilapia using next-generation sequencing (NGS).

spp. in wild rats ( spp.) from the Hainan Province, China: Molecular detection, species/genotype identification and implications for public health.

Wild rats ( spp.) carry many zoonotic pathogens including Due to the close proximity of rats to humans in urban environments, the potential for disease transmission is high. is a protozoan parasite which when ingested causes serious human illness.
