Evidence of a bacterial receptor for lysozyme: binding of lysozyme to the anti-σ factor RsiV controls activation of the ecf σ factor σV. [PDF]

PLoS Genetics, 2014
σ factors endow RNA polymerase with promoter specificity in bacteria. Extra-Cytoplasmic Function (ECF) σ factors represent the largest and most diverse family of σ factors. Most ECF σ factors must be activated in response to an external signal.

Complete Genome Sequences and Pathogenicity Analysis of Two Red Sea Bream Iridoviruses Isolated from Cultured Fish in Korea

Fishes, 2021
In Korea, red sea bream iridovirus (RSIV), especially subtype II, has been the main causative agent of red sea bream iridoviral disease since the 1990s. Herein, we report two Korean RSIV isolates with different subtypes based on the major capsid protein ...

Antibody Detection against Red Sea Bream Iridovirus (RSIV) in Yellowtail Seriola quinqueradiata Using ELISA

Fish Pathology, 2010
FBS components in viral culture fluid inter- fere with the detection of specific antibody in imm unized fish. In the present study, we developed a method to elimi- nate the interference of FBS using a model of red sea bream iridovirus (RSIV) vaccine. In an experiment using yellowtail antiserum against BSA, which is a major compo- nent of FBS in cell ...

Expression of the red sea bream iridovirus (RSIV) capsid protein using a yeast surface display method

Journal of the Korea Academia-Industrial cooperation Society, 2014
The red seabream iridovirus (RSIV), which belongs to the iridoviridae, causes infectious fish diseases in many Asian countries, leading to considerable economic losses to the aquaculture industry. Using the yeast surface display (YSD) technique, a new experimental system was recently developed for the detection and identification of a variety of marine

Establishing environmental DNA and RNA protocols for the simultaneous detection of fish viruses from seawater

Environmental DNA
Aquatic viruses are major threats to global aquacultural productivity. While conventional diagnostic methods for disease investigation are laborious, time‐consuming, and often involve the sacrifice of animals, environmental DNA and RNA (eDNA/eRNA) tools ...

MiR-181a Negatively Regulates Claudin-3 to Facilitate Lateolabrax maculatus Iridovirus Replication in Lateolabrax maculatus Astroglia Cells [PDF]

Viruses
Lateolabrax maculatus iridovirus (LMIV) is a variant strain of red sea bream iridovirus (RSIV), causing serious economic losses in aquaculture. Claudins (CLDNs) are major components of tight junctions (TJs) forming an important line of defense against ...

Divergent survival and viral shedding patterns of red sea bream iridovirus in black sea bream and Japanese sea bass. [PDF]

J Fish Biol
Abstract In open marine aquaculture, rearing diverse fish species in adjacent net pens facilitates the waterborne spread of red sea bream iridovirus (RSIV). This study systematically evaluated the horizontal transmission dynamics of RSIV in black sea bream (BSB, Acanthopagrus schlegelii) and Japanese sea bass (JS, Lateolabrax japonicus) under immersion

A Formalin-Inactivated Vaccine Enhances Survival and Mitigates Horizontal Transmission of Red Sea Bream Iridovirus (RSIV) in Rock Bream (Oplegnathus fasciatus): Insights From Viability Quantitative PCR. [PDF]

J Fish Dis
ABSTRACT Formalin‐inactivated vaccines are widely employed as a primary preventive strategy against red sea bream iridoviral disease (RSIVD), which poses a substantial economic threat to the aquaculture of rock bream (Oplegnathus fasciatus). However, conventional quantitative PCR (qPCR) cannot differentiate infectious virions from noninfectious vaccine
