Isolation of encephalomyocarditis virus from the pheasant (Phasianus colchicus) in Czechoslovakia

Area of Science:

• Veterinary Virology
• Wildlife Disease Surveillance
• Avian Pathology

Background:

• Encephalomyocarditis (EMC) virus is a known pathogen affecting various animal species.
• Understanding the geographic distribution and host range of EMC virus is crucial for disease control.
• Pheasant populations can be susceptible to viral infections, impacting wildlife health.

Purpose of the Study:

• To report the initial isolation of EMC virus from a pheasant.
• To characterize the isolated EMC virus using serological methods.
• To determine if the isolated virus is related to known arboviruses.

Main Methods:

• Virus isolation from blood and brain samples of a pheasant.
• Complement-fixation (CF) tests using reference antisera.
• Comparison with a panel of known arboviruses.

Main Results:

• Encephalomyocarditis (EMC) virus was successfully isolated from a pheasant (Phasianus colchicus) in Moravia.
• Complement-fixation tests indicated no serological relationship between the isolated EMC virus and a broad spectrum of known arboviruses.
• This finding suggests a potentially novel strain or a previously unrecognized host association for EMC virus.

Conclusions:

• This study documents the first isolation of EMC virus from a pheasant.
• The results highlight the importance of wildlife surveillance for emerging viral threats.
• Further research is needed to understand the implications of EMC virus in avian species and its relationship to other viruses.
