Cross-species transmission of coronaviruses (CoVs) represents a serious threat to both animal and human health. Although CoVs have relatively low mutation rates, recombination within certain genera is common. Cats and dogs, often overlooked in viral disease transmission, play a critical role, particularly concerning their similarities to human coronaviruses. Recent findings report a new, highly pathogenic recombinant of feline coronavirus (FCoV) and canine coronavirus (CCoV) responsible for a significant outbreak of feline infectious peritonitis (FIP) in Cyprus. This recombinant demonstrates high sequence identity to the pantropic canine coronavirus, emphasizing the potential for transmission dynamics.
Cross-species transmission of coronaviruses (CoVs) poses a serious threat to both animal and human health. Companion animals, particularly cats and dogs, are critical in this transmission cycle.
A novel, highly pathogenic FCoV-CCoV recombinant has been observed, responsible for a rapidly spreading outbreak of feline infectious peritonitis (FIP) in Cyprus.
The close relationship of feline (FCoV) and canine CoV (CCoV) to human coronaviruses highlights the importance of these animals in potential transmission cycles.
Recombination between coronaviruses, particularly between CCoV and FCoV, has been frequently observed, further complicating the understanding of viral epidemiology.
