Abstract:
Pneumatosis intestinalis (PI) has been described as an incidental finding in domestic animals and humans where it is associated with human immunodeficiency virus infection among other comorbidities. This report describes emphysematous changes consistent with PI in a simian immunodeficiency virus (SIV)-infected rhesus macaque (Macaca mulatta).
Insights
Pneumatosis intestinalis (PI) was observed in a simian immunodeficiency virus (SIV)-infected rhesus macaque. This finding suggests PI may occur in SIV-infected non-human primates, similar to human immunodeficiency virus (HIV) cases.
Area of Science:
- Veterinary Pathology
- Primate Virology
- Gastrointestinal Diseases
Background:
- Pneumatosis intestinalis (PI) is a rare condition characterized by gas in the intestinal wall.
- PI is often an incidental finding in domestic animals and humans.
- PI has been associated with various comorbidities, including human immunodeficiency virus (HIV) infection.
Observation:
- This report details emphysematous changes consistent with PI.
- The observation was made in a rhesus macaque (Macaca mulatta).
- The rhesus macaque was infected with simian immunodeficiency virus (SIV).
Findings:
- This case presents emphysematous changes indicative of PI in an SIV-infected non-human primate.
- This finding expands the known associations of PI to SIV infection in macaques.
Implications:
- The study suggests a potential link between SIV infection and PI in non-human primates.
- This finding may inform veterinary diagnostics and research into gastrointestinal manifestations of lentiviral infections.
- Further research is warranted to understand the pathogenesis and clinical significance of PI in SIV-infected macaques.
