Summary
Two aquatic morbilliviruses cause marine mammal deaths, impacting multiple species with varying susceptibility. Interspecific transmission likely drives differences between aquatic and terrestrial morbillivirus dynamics.
Area of Science:
- Marine biology
- Virology
- Ecology
Background:
- Morbilliviruses are known pathogens causing significant mortality in terrestrial mammals.
- Recently discovered aquatic morbilliviruses pose a threat to marine ecosystems.
- Two specific aquatic morbilliviruses have been linked to mass mortality events in marine mammals.
Purpose of the Study:
- To investigate the transmission dynamics of aquatic morbilliviruses.
- To compare the ecological behavior of aquatic morbilliviruses with their terrestrial relatives.
- To understand the factors influencing susceptibility and mortality in different marine host species.
Main Methods:
- Analysis of mortality data from marine mammal populations.
- Comparative analysis of host species susceptibility.
- Epidemiological modeling to assess transmission patterns.
Main Results:
- Two aquatic morbilliviruses identified as causes of significant marine mammal die-offs.
- Observed variation in susceptibility to infection across different marine mammal species.
- Evidence suggesting high levels of interspecific transmission are characteristic of these aquatic viruses.
Conclusions:
- Aquatic morbilliviruses exhibit unique transmission dynamics compared to terrestrial strains.
- Interspecific transmission is a key factor shaping the epidemiology of marine mammal morbilliviruses.
- Understanding these dynamics is crucial for marine mammal conservation and disease management.

Viral Recombination
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
Retroviruses
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
