What are symptoms of reovirus?
Infants and young children most commonly have fever, vomiting, diarrhea, and (occasionally) dehydration. Vomiting, usually short-lived, can occur before or after the onset of diarrhea. Symptoms of an apparent respiratory infection may be present.
How is reovirus diagnosis?
Diagnosis is commonly accomplished via serology (ELISA, MFIA™, IFA), but may also be performed via PCR. Natural infection with reovirus is not proven to be specifically linked to interference with research.
Can humans get reovirus?
Reovirus infections occur often in humans, but most cases are mild or subclinical. Rotaviruses, however, can cause severe diarrhea and intestinal distress in children, and lab studies in mice have implicated orthoreoviruses in the expression of coeliac disease in pre-disposed individuals.
What causes reovirus?
Most of the plant-infecting reoviruses are transmitted between plants by insect vectors. The viruses replicate in both the plant and the insect, generally causing disease in the plant, but little or no harm to the infected insect.
What type of virus is reovirus?
Reovirus is a nonenveloped double-stranded RNA virus. This virus was initially not known to be related to any specific disease, and so was named Respiratory Enteric Orphan virus. However, some members of the reovirus family have been shown to cause mild illnesses such as diarrhea [5,30].
What causes human reovirus?
Human volunteer studies have failed to demonstrate a clear cause-and-effect relationship between reoviruses and human illness. The method of transmission of reoviruses is unknown. However, because these viruses are recovered most frequently from the feces, primary spread seems most likely to be by the fecal-oral route.
What are the symptoms of reovirus in chickens?
The most frequent reovirus-associated disease in poultry is viral arthritis. Clinically it is manifested by lameness and swellings affecting primarily tarsometatarsal joints and the feet. Many infected birds are in a good general condition, but some could be lethargic and exhausted.
What is the most common reovirus in poultry?
271. Viral arthritis/tenosynovitis. The most frequent reovirus-associated disease in poultry is viral arthritis. Clinically it is manifested by lameness and swellings affecting primarily tarsometatarsal joints and the feet. Many infected birds are in a good general condition, but some could be lethargic and exhausted. The mortality is very low.
What are the risks of avian reoviruses?
This family of viruses can cause a range of health problems in poultry. Avian reoviruses are a costly challenge for poultry producers, leading to lameness in broilers, increased culling and mortality and low rates of weight gain and poor feed efficiency.
How do you control avian reoviruses in poultry?
Carefully-planned biosecurity measures are the best want to control avian reoviruses in poultry flocks. “Some control measures include biosecurity, such as limited distribution of eggs and chicks from infected breeder flocks and limiting moves of outside eggs that may not be coming from vaccinated breeders.
