Summary
Rabbit coronavirus (RbCoV) and parvovirus (LBoV) are implicated in rabbit digestive diseases. Their presence and associated lesions confirm their role, especially in growing rabbits alongside bacterial agents.
Area of Science:
- Veterinary Virology
- Rabbit Pathology
- Gastroenterology
Background:
- The role of rabbit coronavirus (RbCoV) and parvovirus (LBoV) in rabbit enteric diseases is not well understood.
- Digestive issues significantly impact rabbit farming operations.
Purpose of the Study:
- To investigate the prevalence and role of RbCoV and LBoV in rabbit enteric diseases.
- To identify potential co-factors and risk factors associated with these viral infections.
Main Methods:
- Quantitative PCR (qPCR) for viral detection and quantification.
- Histopathological examination of intestinal lesions.
- Epidemiological analysis of viral prevalence in relation to age and bacterial co-infections.
Main Results:
- qPCR detected RbCoV and LBoV in rabbits with digestive disorders, with varying Cq values.
- Lesional studies confirmed characteristic viral pathology, often alongside other infectious agents.
- Epidemiological data showed higher viral prevalence in growing rabbits, associated with *Escherichia coli* and *Clostridium spiroforme*.
Conclusions:
- RbCoV and LBoV are significant contributors to the aetiology of rabbit enteric disease.
- These viruses should be considered in the diagnostic profile for rabbit enteritis.
- Understanding viral-bacterial interactions is crucial for managing rabbit digestive health.

01:29Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
01:28Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
