malacoherpesviruses

Malacoherpesviruses are a family of viruses that infect mollusks. The name comes from the Greek word "malakion" meaning mollusk and "herpes" referring to their resemblance to herpesviruses. These viruses are characterized by their double-stranded DNA genome and their icosahedral capsid. They are enveloped viruses, meaning they have an outer lipid membrane.

Malacoherpesviruses have been identified in a wide range of mollusk species, including bivalves like oysters and mussels, as well as gastropods like snails and slugs. The infections can range from asymptomatic to causing significant mortality in host populations. Symptoms, when present, can include tissue lesions, developmental abnormalities, and reduced growth rates.

Research into malacoherpesviruses is ongoing, with a focus on understanding their replication cycles, pathogenesis, and ecological impact. Their study is important for both understanding mollusk health and for potential applications in fields such as aquaculture. Some malacoherpesviruses have been shown to be specific to certain mollusk species, while others may have a broader host range. The prevalence and impact of these viruses can vary greatly depending on environmental factors and the health of the mollusk populations.
