Summary
Bovine rotavirus strains, identified as G(6)P(1), were isolated from diarrheic turkeys. This suggests a cattle-to-turkey transmission route, impacting turkey farm health.
Area of Science:
- Veterinary Virology
- Animal Gastroenteritis
Background:
- Rotaviruses cause diarrhea in animals and humans.
- Poult enteritis and mortality syndrome is linked to avian rotaviruses.
- Rotavirus infection in turkeys is not well understood.
Purpose of the Study:
- To investigate rotavirus strains in diarrheic turkeys.
- To determine the origin and genetic characteristics of turkey rotaviruses.
Main Methods:
- Isolation of rotavirus strains from turkey enteric contents in MA-104 cell culture.
- Genotyping of rotavirus strains (G and P types).
- Electropherotyping and NSP4 gene phylogenetic analysis.
Main Results:
- Six group A rotavirus strains were isolated and identified as G(6)P(1).
- These strains share genetic characteristics with bovine rotaviruses (Nebraska calf diarrhea virus).
- Phylogenetic analysis of the NSP4 gene placed all strains within genotype E2.
Conclusions:
- Bovine-origin rotaviruses can infect turkeys.
- A cattle-to-turkey transmission route for rotavirus is proposed.
- This finding is crucial for improving turkey farm health management.

01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
01:21Acute Pancreatitis II: Pathophysiology
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
