New All-Species Test Offers Enhanced Insights into COVID-19 Infection in Animals
In a groundbreaking development, researchers have unveiled a new all-species test capable of detecting the presence of the COVID-19 virus in animals. This pioneering test represents a significant advancement that promises to enhance our ability to track COVID-19 variants in both wild and domesticated animals.
The urgent need for highly sensitive and specific diagnostic tools in animals prompted the researchers to explore this innovative approach. The study was led by Ying Fang, a distinguished virologist and pathobiology professor at the University of Illinois Urbana-Champaign. The team’s findings, published on July 6 in the journal mSphere, shed light on the importance of this new testing method.
It is well-known that animals such as cats, dogs, rodents, deer, apes, and various farm and zoo animals can host the SARS-CoV-2 virus, which causes COVID-19. Moreover, the virus has the ability to mutate within these animal hosts, giving rise to new variants that have the potential to impact human health.
The test developed by Fang and her team stands apart from conventional coronavirus tests by targeting antibodies against the nucleocapsid (N) protein. The N-protein is an essential component of the virus found within the nucleocapsid. Unlike other proteins used in most tests, the N-protein is more abundant and remarkably consistent across different species. This inherent stability makes it an excellent marker for all-species antibody tests.
To validate their test, the researchers used samples from various animals with known COVID-19 infection statuses. The tests exhibited an impressive 97% sensitivity and 98% specificity, ensuring accurate and reliable results. Notably, the test proved effective in detecting infection in domestic cats within just seven days of exposure to the virus.

The implications of this breakthrough are vast. With the ability to accurately identify COVID-19 infections in animals, scientists can now conduct surveillance and closely monitor animal populations. This proactive approach will not only aid in preventing future disease outbreaks but also provide crucial insights into the transmission dynamics and potential cross-species transmission of the virus.
The research was generously supported by the U.S. National Institutes of Health, highlighting the significance of this work in understanding and combating the COVID-19 pandemic.
In conclusion, the advent of the all-species test signals a major step forward in our fight against the global health crisis that is COVID-19. With its high sensitivity and specificity, this test equips researchers and healthcare professionals with an invaluable tool for understanding the virus’s behavior and its impact on both humans and animals. By comprehensively monitoring the spread of the virus in animal populations, we gain a vital edge in preventing future disease outbreaks and protecting public health.
