30. Hepeviridae, Hepadnaviridae, Genus Deltavirus, Nodaviridae, Unclassified

Question 2

MEMBERS OF THE FAMILY HEPEVIRIDAE (2 genera)

Answer 2

1. Genus Orthohepevirus with four separate species (Orthohepeviruses A-D) that include the so-called “hepatitis E-like viruses”—reflecting the sequential designation of human viral hepatitis—from mammals and birds
2. Genus Piscihepevirus with a single virus species from fish: Piscihepevirus A, which is more commonly known by its historic name of cutthroat trout virus.

Question 3

MEMBERS OF THE GENUS ORTHOHEPEVIRUS (FAM. HEPEVIRIDAE) (4 species)

Answer 3

1. Orthohepevirus A (the type species of hepatitis E virus), including hepeviruses from humans, domestic and wild pigs, deer, mongoose, rabbits, and camels;
2. Orthohepevirus B, which includes the avian hepeviruses;
3. Orthohepevirus C, which includes strains of hepevirus from rats, Asian musk shrews, ferrets, and mink;
4. Orthohepevirus D, which includes hepeviruses from bats.

Question 4

MEMBERS OF THE GENUS HEPACIVIRUS

Answer 4

Nonprimate hepaciviruses (contains hepatitis C virus, an important cause of human hepatitis) / Horses, dogs, etc. / Uncertain Hepatitis possibly in horses. Persistent infection / Apparently worldwide

Question 5

MEMBERS OF THE FAMILY HEPADNAVIRIDAE - hepatitis DNA viruses -(2 genera)

Answer 5

1. Genus Orthohepadnavirus includes:
   
   1. human hepatitis B
   2. a number of genotypes of related primate hepatitis B virus that infect great apes and woolly monkeys, as well as
   3. several viruses that infect members of the squirrel family: woodchuck hepatitis virus, which infects woodchucks (Marmata monax) and chipmunks (family Sciuridae), and
   4. ground squirrel hepatitis virus, which infects ground squirrels (Spermophilus beecheyi, richardsonii and S. parryi).
   5. Bats also can be infected with a hepadnavirus.
2. Genus Avihepadnavirus include:
   
   1. duck hepatitis B virus, ducks and geese;
   2. a number of similar viruses occur in other species of birds, including storks, herons, and cranes.

Question 6

MEMBERS OF THE FLOATING GENUS DELTAVIRUS (1 species)

Answer 6

Hepatitis D virus, also called hepatitis delta virus, is a small, replication-defective RNA virus.

The virus requires the simultaneous presence of hepatitis B virus for its replication and assembly in natural infections.
