Published: March 2022

A persistent 2-month long outbreak of Ranavirus in a natural community of amphibians contributed to a mass die-off of gopher frog tadpoles (Lithobates capito) and severe disease in striped newts (Notophthalmus perstriatus) in Florida. Ongoing mortality in L. capito and disease signs in N. perstriatus continued for 5 weeks after the first observation. Hemorrhagic disease and necrosis were diagnosed from pathological examination of L. capito tadpoles. We confirmed detection of a frog virus 3 (FV3)-like Ranavirus via quantitative PCR in all species. Our findings highlight the susceptibility of these species to Rv and the need for long-term disease surveillance during epizootics.

Article Synopsis
  • Researchers successfully created an immortal cell line (MSF) from the fin tissue of Largemouth bass, which can be cultured continuously for over 80 passages.
  • The MSF cells, maintained at 28°C and confirmed to be free from mycoplasma contamination, are identified as epithelialoid cells with specific chromosome characteristics.
  • This new cell line is highly susceptible to various viruses affecting Largemouth bass, making it a valuable tool for future studies on gene expression and viral mechanics.

Article Synopsis
  • * Turtles from the CDF showed signs of higher stress, including elevated glucose levels and altered blood metrics, compared to those from the PCM, which appeared healthier.
  • * Additionally, some turtles tested positive for Chlamydia, with a small number also showing co-infection with herpesvirus, highlighting the need to monitor the impacts of human-altered habitats on wildlife health.

Largemouth bass ranavirus (LMBRaV), also known as largemouth bass virus (LMBV), is a highly damaging viral pathogen that causes widespread mortality in cultured largemouth bass and poses a significant threat to the farming industry in China. However, there is a paucity of effective preventive methods for this disease by LMBRaV. Research has established that herbal extracts possess antiviral activity, potentially exerting a controlling effect on viruses in aquaculture.

Genome-Wide Association Study of Resistance to Largemouth Bass Ranavirus (LMBV) in .

The disease caused by Largemouth bass ranavirus (LMBV) is one of the most severe viral diseases in largemouth bass (). It is crucial to evaluate the genetic resistance of largemouth bass to LMBV and develop markers for disease-resistance breeding. In this study, 100 individuals (45 resistant and 55 susceptible) were sequenced and evaluated for resistance to LMBV and a total of 2,579,770 variant sites (SNPs-single-nucleotide polymorphisms (SNPs) and insertions-deletions (InDels)) were identified.

Largemouth bass ranavirus (LMBV) causes disease outbreaks and high mortality at all stages of largemouth bass farming. Therefore, live vaccine development is critical for largemouth bass prevention against LMBV by immersion immunization. Herein, an attenuated LMBV strain with good immunogenicity, designated as LMBV-2007136, was screened from the natural LMBV strains bank through challenge assay and immersion immunization experiment.
