The preferred hosts of this tick are camels (Camelus dromedarius), but cattle, sheep, goats and horses may also be infested. The larvae and the nymphs feed on small burrowing animals and on hares, but the nymphs may also infest camels, cattle and horses. I think yes it may infest also bacterian camel.
The worst damage of Hy dromedarii is caused by the his nymphs. In immature and calves they can be literally 10 thousands plus causing profound anemia. Nymphs prefer to attach on the body area with longer coat: chest , hump. They are therefore not visible and the only way to detect them is by manually touching these area and detecting the ticks.
I think the Hyaloma tick need more blood and this area riched with blood and also this place of nostrils is worm environment and tick also need warm places to live and scking blood.
