[Spontaneous coronavirus infection in monkeys]
Coronavirus (CV) infection is widespread in monkeys, affecting the gastrointestinal and respiratory systems. This animal model offers insights into human CV infection pathogenesis and epidemiology.
Area of Science:
- Veterinary Virology
- Primate Infectious Diseases
- Coronaviruses
Background:
- Coronaviruses (CV) can infect various primate species.
- Understanding CV tropism and disease course in animal models is crucial.
Purpose of the Study:
- To investigate the prevalence and characteristics of spontaneous coronavirus infection in hamadryas baboons and macaques.
- To explore the potential of using simian CV infection models for human CV research.
Main Methods:
- Serological testing to determine antibody titers against simian and human CV strains.
- Clinical and pathological examination of infected animals.
Main Results:
- A high prevalence (approx. 50%) of CV infection was observed in resident and imported hamadryas baboons and macaques.
- CV tropism was confirmed in the gastrointestinal and respiratory tracts.
- Infected macaques showed elevated antibody titers to homologous and related human CV strains (0043).
- Infection manifested as enterocolitis, pneumonia, inapparent forms, or persistent infections.
Conclusions:
- Spontaneous CV infection is common in these monkey species.
- The observed clinical and immunological responses provide a valuable model for studying CV pathogenesis and epidemiology in humans.
