The Dromedary camel has a remarkable history amongst cultures across Asia and northern Africa, serving multiple purposes ranging from providing milk, textiles, racing, and acting as pack animals. Recent genetic studies have revealed that many dromedaries are genetically homogenous, indicating that they do not represent different breeds, advocating for camel 'type' over camel 'breed'. In this study, we leveraged whole genome sequencing (WGS) to sequence 15 Jordanian Alia camels for the first time, alongside 9 Jordanian mixed camels from diverse locations within the country.

Novel transmission routes can allow infectious diseases to spread, often with devastating consequences. Ectoparasitic varroa mites vector a diversity of RNA viruses, having switched hosts from the eastern to western honey bees ( to ). They provide an opportunity to explore how novel transmission routes shape disease epidemiology.

In 1977, a sample of diseased adult honeybees (Apis mellifera) from Egypt was found to contain large amounts of a previously unknown virus, Egypt bee virus, which was subsequently shown to be serologically related to deformed wing virus (DWV). By sequencing the original isolate, we demonstrate that Egypt bee virus is in fact a fourth unique, major variant of DWV (DWV-D): more closely related to DWV-C than to either DWV-A or DWV-B. DWV-A and DWV-B are the most common DWV variants worldwide due to their close relationship and transmission by Varroa destructor.

Using high-throughput sequencing technology, the complete mitochondrial genome of Awassi-Jo breed () was decoded. Mitochondrial genome was 16,617 bp in length. The genome contained 37 genes (13 protein-coding, 22 tRNA, and 2 rRNA) and a control region (D-loop region).

The Oriental Hornet () is a social insect belonging to the Vespiade family (Wasps, Hornets, Yellowjackets), genus (true Hornets). The oriental hornet is a scavenger and an agricultural pest, especially to bee farmers, but is also recently described as a harvester of solar energy. Here, we report the mitochondrial genome sequence of the Oriental Hornet, .

Apis mellifera syriaca is the native honeybee subspecies of Jordan and much of the Levant region. It expresses behavioral adaptations to a regional climate with very high temperatures, nectar dearth in summer, attacks of the Oriental wasp and is resistant to Varroa mites. The A.

Three hundred and eleven honeybee samples from 12 countries in the Middle East and North Africa (MENA) (Jordan, Lebanon, Syria, Iraq, Egypt, Libya, Tunisia, Algeria, Morocco, Yemen, Palestine, and Sudan) were analyzed for the presence of deformed wing virus (DWV). The prevalence of DWV throughout the MENA region was pervasive, but variable. The highest prevalence was found in Lebanon and Syria, with prevalence dropping in Palestine, Jordan, and Egypt before increasing slightly moving westwards to Algeria and Morocco Phylogenetic analysis of a 194 nucleotide section of the DWV Lp gene did not identify any significant phylogenetic resolution among the samples, although the sequences did show consistent regional clustering, including an interesting geographic gradient from Morocco through North Africa to Jordan and Syria.

The mitochondrial genome sequence of Levant Region honeybee, Apis mellifera syriaca, is analyzed and presented for the public for the first time. The genome of this honeybee is 15,428 bp in its length, containing 13 protein-coding genes, 22 transfer RNA genes and 2 ribosomal RNA genes. The overall base composition is A (42.
