“…[126][127][128] Despite the wide tolerance range, rapid fluctuation in salinity is associated with increased susceptibility to pathogens and increased incidence of disease outbreaks. [129][130][131][132] Beyond the physiological stress and energetic cost to maintain osmotic homeostasis resulting in reduced capacity for immune response, 124,133 fluctuating salinity may also be a key mechanism of viral entry into shrimp. 81 During conditions causing increased frequency of urination (i.e., osmotic stress following a sudden drop in environmental salinity), the recurrent opening of the nephropore (antennal gland) for urination to regulate haemocoel volume may increase the opportunity for pathogen exposure to the nephrocomplex.…”

The success of contemporary disease management strategies in shrimp aquaculture, such as the ‘systems’ approach, is predicated on robust knowledge of the conditions and interactions between the host, pathogen and environment that promote disease. Pathogen challenge experiments (PCEs) are a power tool for investigating these conditions and interactions. However, absence of accurately reported experimental detail in published PCEs limits scientific transparency, reproducibility, and the potential for the research to make progressive advancements contributing to contemporary shrimp disease management strategies. This review identifies and discusses key factors relating to the host (shrimp), pathogen (virus), and environment that should be carefully considered during the design and publication of PCEs. We offer substantial evidence of their impact on viral disease outcomes, drawn from the existing body of literature, to supporting their consideration. The prevalence of reported experimental details for these factors across 186 viral PCEs in shrimp were evaluated. The review highlights a concerning paucity of experimental detail reported in published shrimp PCEs. We propose a checklist for the minimum reportable information in the publication of shrimp viral PCEs, hereafter referred to as the Shrimp PCE Reporting Guidelines (SPERG). The guidelines aim to enhance the transparency and standardisation of reporting in published PCEs, ensuring that key factors pertaining to the shrimp, pathogen, and environment are adequately considered and documented. Adoption of SPERG is envisaged to empower researchers, reviewers, and readers to assess the internal and external validity of PCEs, facilitating critical evaluation and improved utility of PCE findings for contemporary disease management.

“…Based on genomic mapping conducted by Marks et al (2004) on WSSV strains collected La identificación de las regiones variables del ADN, han permitido tipificar al genoma del VSMB en diferentes países de América (Muller et al, 2010;Ramos-Paredes et al, 2017;Pereira et al, 2019;Rodrigues et al, 2020), África (Tang et al, 2013;Onihary et al, 2021) y Asia (Dieu et al, 2004;Pradeep et al, 2008;Li et al, 2016;Min et al, 2023). Además, ha permitido reconstruir las rutas epidemiológicas que ha seguido el VSMB durante su dispersión a través del mundo (Zeng, 2021), así como también evaluar los cambios que se pueden presentar en su virulencia (Marks et al, 2005;Li et al, 2016;Ramos-Paredes et al, 2017;Min et al, 2023).…”

This information has enabled the reconstruction of the epidemiological routes taken by WSSV during its global dissemination (Zeng, 2021), and the assessment of potential changes in virulence (Marks et al, 2005;Li et al, 2016;Ramos-Paredes et al, 2017;Min et al, 2023).…”

El virus del síndrome de las manchas blancas (VSMB), es uno de los principales patógenos de langostinos peneidos reportado a nivel mundial. Desde su primera aparición hasta la actualidad, el VSMB ha mostrado una notable capacidad para alterar su estructura genética, lo que ha dado lugar a diversidad de genotipos. Con el objetivo de detectar las variantes genotípicas del VSMB presentes en el cultivo de langostinos de la costa norte del Perú (Región Tumbes), en esta investigación, se evaluaron 89 muestras de branquias y postlarvas de langostinos infectados con el VSMB que fueron colectados entre los años 2014 y 2021. El análisis fue realizado mediante la PCR (reacción en cadena de la polimerasa) y secuenciamiento de regiones variables del ADN, ubicados en los marcos de lectura abierta (ORFs= open reading frame) 75, 94, 125, 14/15, 23/24 y un gen transposasa presuntiva. En comparación con los genomas de referencia del VSMB, todas las muestras analizadas presentaron deleciones de 5138 pb en el ORF 14/15, de 11110 pb en el ORF 23/24 y de 1338 pb en un gen transposasa presuntiva. A nivel de los ORFs 75, 94 y 125, se observó variación en la cantidad de secuencias repetitivas de 6 a 8, 1 a 3 y 2 a 13, respectivamente; esta variación permitió detectar hasta 8 genotipos de VSMB presentes en los langostinos de cultivo de la zona norte de Perú. El hallazgo inicial de estos genotipos representa un logro significativo que sentará las bases para futuros estudios epidemiológicos del VSMB en langostinos de cultivo y silvestres en esta región geográfica.

White spot syndrome virus (WSSV) has been one of the most devastating pathogens affecting the global shrimp industry since its initial outbreaks in Asia in the early 1990s. In this study, we recovered 13 complete metagenome-assembled genomes (MAGs) of Japanese WSSV isolates and 30 draft WSSV MAGs recovered from publicly available sequencing data, to investigate the genomic evolution of WSSV. Phylogenetic analysis revealed two major phylotypes, designated phylotypes I and II. Bayesian divergence time estimates placed the divergence time of the two phylotypes between 1970 and the early 1980s, with an estimated substitution rate of 1.1 × 10–5 substitutions per site per year, implying the existence of pre-pandemic genetic diversity of WSSV in Asia. Based on this scenario, phylotype I was responsible for the 1990s pandemic and spread worldwide, whereas phylotype II was localized in Asia and infiltrated Australia. Two cross-phylotype recombinant lineages were identified, which demonstrate the role of genomic recombination in generating the genetic diversity of WSSV. These results provide important insights into the evolution of WSSV and may help uncover the ultimate origins of this devastating pathogen.
