Bunyavirus

Bunyavirus has high levels of morbidity and mortality, consequently handling of these viruses must occur with a Biosafety 4 laboratory.

Arterivirus

Arteriviruses are positive-stranded RNA viruses that infect mammals and can cause persistent or symptomatic infections, but also acute diseases associated with a respiratory syndrome, abortion or lethal haemorrhagic fever

Torovirus

Torovirus primarily infects vertebrates- especially humans, cattle, pigs, and horses. It has been detected in diarrheic stool samples- prevalence rates of 22-35%. Respiratory problems viz, laryngitis, tracheitis, and pneumonia have also been documented with these viruses

Prion

Prions are the shortened term for Proteinaeous infectious particles. They are small infectious proteins that cause fatal neurodegeneration in humans and animals and have no detectable nucleic acid.

Hepatitis E virus

Hepatitis E virus is the primary cause of enterically transmitted non-A non-B hepatitis virus (NANBH). It is a non-enveloped, spherical, 32-34nm in diameter, positive ssRNA, genome enclosed within a capsid composed of 60 capsid proteins.

Hepatitis D virus

Hepatitis D virus is an RNA virus. It is an incomplete virus and requires the presence of HBV to replicate and infect other hepatocytes. Hence, HDV infection occurs only in patients who suffer from HBV infection

Hepatitis C virus

Hepatitis C virus is an important cause of parenteral non-A, non-B hepatitis (NANBH) worldwide. It is spherical (50nm in diameter), enveloped, icosahedral nucleocapsid core, positive-sense ssRNA virus (9.4 kb)

Hepatitis B virus

Hepatitis B virus is the major cause of infectious hepatitis worldwide. it shows restricted host range and limited tissue tropism, and usually causes chronic disease and is associated with hepatocellular carcinoma.

Hepatitis A virus

Hepatitis A virus is a small, non-enveloped virus measuring 27 nm in diameter with icosahedral symmetry. It has a single-stranded positive-sense liner RNA genome which is approximately 7.5kb. The capsid consists of multiple copies of 3-4 proteins (VP1 to VP4).
