Ornithodoros erraticus is a species of tick in the family Argasidae. The tick was described by Hippolyte Lucas in 1849 as Argas erraticus from individuals collected in northern Algeria.
Description
The tick is native to the Middle East and Mediterranean. It is one of the more common soft ticks to bite humans. Their main food sources in Spain are pigs; the tick has been found in pig pens in the provinces of Salamanca, Badajoz, and Huelva. The only human habitats the tick can enter are places in poor condition.
The tick feeds at night, ingesting blood to repletion in about 15 minutes. Small mammals are the most common hosts; this species rarely bites humans, preferring other vertebrates. The tick has substances in its saliva, such as antihemostatic, anti-inflammatory, and immunomodulatory molecules, which help the tick get blood from the host and transfer pathogens easily. Major factors in their feeding relationship are mating, recent feeding, and size.
Some strains of entomopathogenic fungi have been found to be effective against this tick and others in the related genus Ornithodoros in a study which concluded the fungi could be used as biocontrol agents for argasid ticks; the name of this is called hyperparasitism.
