Short-Finned Pilot Whale Strandings Associated with Pilot Whale Morbillivirus, Brazil
Abstract:
Cetacean morbillivirus (CeMV) causes illness and death in cetaceans worldwide; the CeMV strains circulating in the Southern Hemisphere are poorly known. We detected a pilot whale CeMV strain in 3 short-finned pilot whales (Globicephala macrorhynchus) stranded in Brazil during July-October 2020. Our results confirm this virus circulates in this species.
Insights
Cetacean morbillivirus (CeMV) causes widespread cetacean illness. A new CeMV strain was identified in Brazilian short-finned pilot whales, confirming its circulation in the Southern Hemisphere.
Area of Science:
- Marine biology
- Virology
- Wildlife health
Background:
- Cetacean morbillivirus (CeMV) poses a global threat to marine mammals.
- Limited data exists on CeMV strains in the Southern Hemisphere.
Discussion:
- This study reports the detection of a pilot whale CeMV strain.
- The virus was identified in three short-finned pilot whales stranded in Brazil between July and October 2020.
Key Insights:
- Confirms the circulation of CeMV in short-finned pilot whales (Globicephala macrorhynchus) in Brazil.
- Highlights the presence of specific CeMV strains in the Southern Hemisphere.
Outlook:
- Further research is needed to understand the prevalence and impact of this CeMV strain.
- Monitoring CeMV in cetacean populations is crucial for conservation efforts.
