Abstract
Recognizing the economic importance of Camelus dromedarius underscores the need for attention to parasitic diseases that threaten their health and productivity, particularly blood parasites and ticks. To investigate this issue, camel blood samples were collected at the Al-Basatein and Berqash Slaughterhouses to diagnose blood parasites using microscopic and molecular techniques. Additionally, evaluate the effectiveness of the entomopathogenic fungus, Metarhizium anisopliae, in controlling these as an alternative biological agent. Three genera of ticks were identified: Hylomma sp., Amblyomma sp., and Rhipicephalus sp. Specifically, four species were characterized among the ticks: H. dromedarii (79.4%), A. lepidum (18.9%), A. variegatum (0.7%), and R. pulchellus (1.1%). Microscopic examination revealed the presence of several parasites, including Theileria spp. (53.01%), Trypanosoma evansi (2.2%), and Dipetalonema evansi (0.75%). Phylogenetic analysis of T. annulata tams1 gene sequences revealed two isolates that have been deposited in the GenBank database under the accession numbers OQ640226 and OQ640227. The alternative tick control strategy used Metarhizium anisopliae (at a concentration of 106 spores/ml), which was tested against H. dromedarii ticks by dipping and spraying applications. The mortality rates reached 63.33% and 76.66% for both applications. Additionally, there was a reduction in all reproductive parameters.
