Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

Rheumatic Heart Disease I: Introduction

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Summary

This summary is machine-generated.

A female reticulated python experienced lethargy and weakness due to dystocia and stomatitis. Postmortem revealed 26 eggs and an endocardial fibrosarcoma, a rare cardiac tumor in reptiles.

Area of Science:

Veterinary Pathology
Reptile Medicine
Comparative Oncology

Background:

Dystocia and coelomic distention are critical conditions in female reptiles.
Reproductive and cardiac pathologies can present with similar clinical signs.
Reticulated pythons (Python reticularis) are susceptible to various health issues.

Observation:

A female reticulated python presented with severe lethargy, weakness, and abdominal distention.
Clinical signs included severe dystocia and stomatitis.
Euthanasia was elected due to the poor prognosis.

Findings:

Postmortem examination revealed a distended reproductive tract with 26 large eggs and significant pericardial effusion.
A cardiac mass adhered to the endocardium at the aortic base was identified.
Histopathology and electron microscopy confirmed the mass as an endocardial fibrosarcoma.

Implications:

This case highlights the importance of thorough postmortem diagnostics in reptiles with complex presentations.
Endocardial fibrosarcoma is a rare cardiac tumor, and this is a notable case in a python.
Understanding reproductive and cardiac disease interactions is crucial for reptile veterinary care.
