Dear MARMAM community,

on behalf of my co-authors, I am happy to share with you a new publication:

"First description of a Gammaherpesvirus in a common dolphin (Delphinus
delphis) from the Eastern Mediterranean Sea"

Abstract

In September 2020, a male common dolphin (*Delphinus delphis*) was found
dead on a beach near Bat-Yam, Israel. A small, raised, well circumscribed
penile lesion (*i.e.,* mass) was identified and removed for histology and
molecular characterizations. By histology, the penile mass presented focal
keratinization of the squamous epithelium and a mild ballooning of
acanthocytes in lower epithelium levels, as well as features compatible
with viral plaques, and tested positive for a gammaherpesvirus through
molecular characterization analyses. Tissue samples from the lungs, liver,
and spleen, however, tested negative for herpesvirus infection. The
gammaherpesvirus detected herein is similar to other isolates found in
several areas worldwide in different cetacean species. This is the first
reported case of gammaherpesvirus infection in dolphins from the eastern
Mediterranean Sea, indicative of the need for long-term assessments to
create viral infections databases in cetaceans, especially in a climate
change context, which is likely to intensify infectious disease outbreaks
in marine mammals in the future.
