Abu Hammad Virus
Abu Hammad virus (AHV), is a species of virus in the genus ''Orthonairovirus''. It was isolated from a tick, ''Argas hermanni'', in Egypt. This virus doesn't cause disease in humans. Abu Hammad virus shares an intergroup relationship with viruses of serogroups (CHF-CON, HUG, NSD, QYB, and SAK), all of which make up the ''Nairovirus ''Orthonairovirus'' is a genus of viruses in the family ''Nairoviridae'' of the order ''Hareavirales'' which includes viruses with circular, RNA virus#Group V - negative-sense ssRNA viruses, negative-sense single stranded RNA.

Orthonairovirus
''Orthonairovirus'' is a genus of viruses in the family '' Nairoviridae'' of the order '' Hareavirales'' which includes viruses with circular, negative-sense single stranded RNA. The name is derived from the Nairobi sheep disease which affects the gastrointestinal tracts of sheep and goats. All viruses in this genus are tick-borne viruses with human or other vertebrate hosts. Structure The virions for viruses in this genus have a spherical shape. They range in size from about 80–120 nm in diameter, with 50% of their weight attributed to proteins and 20–30% of their weight attributed to lipids. The ribonucleocapsid is filamentous, having a length of about 200-300 nm and a width of about 2–2.5 nm. These nucleocapsids are surrounded by a single envelope that has projections made of glycoproteins protruding from its surface. These projections evenly cover the surface of the virion, and are about 5–10 nm long. They aid in attachment to the host r ...

Tick
Ticks are parasitic arachnids of the order Ixodida. They are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, and species, but can become larger when engorged. Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are around 100 million years old, and come from the Cretaceous period. Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families: the Ixodidae, or hard ticks, and the Argasidae, or soft ticks. '' Nuttalliella'', a genus of tick from southern Africa, is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks. Adults have ovoid/pear-shaped bodies (idiosomas) which become engorged with blood when they feed, and eight legs. Their cephalotho ...
