| chromosomal rearrangements in a somali wild ass pedigree, equus africanus somaliensis (perissodactyla, equidae). | chromosome analyses were conducted on 15 animals in a pedigree of somali wild ass, equus africanus somaliensis. g- and c-banded karyotypes are presented for the first time on this endangered species. the diploid number ranged from 62 to 64. numerical chromosomal variation was the result of a centric fission which was accompanied by a heterochromatic deletion. the fission polymorphism involved acrocentric elements 19 and 21 as determined by g-banding. these autosomes are homologous to those invol ... | 1998 | 9678344 |
| clinical, virological and immune responses of normal and immunosuppressed donkeys (equus asinus africanus) after inoculation with african horse sickness virus. | to elucidate the role that donkeys may play in african horse sickness virus (ahsv) persistence during inter-epizootic periods we looked for clinical signs of infection and studied the viraemia and neutralising antibody kinetics in 3 immunocompetent and 3 immunosuppressed donkeys inoculated with ahsv-4. none of the donkeys developed signs of ahs. however infectious ahsv was isolated from the blood of the immunocompetent donkeys for up to 17 days post infection (dpi) and viral antigens were detect ... | 1998 | 9785495 |
| the prevalence and transmission to exotic equids (equus quagga antiquorum, equus przewalskii, equus africanus) of intestinal nematodes in contaminated pasture in two wild animal parks. | wild equids maintained in large enclosures may suffer from helminth diseases because common hygiene practices have only limited effects on parasite populations. weekly monitoring of helminth prevalences and pasture infestation was performed for 1 yr in several extensive maintenance systems of two wildlife parks with similar climates to determine when veterinary intervention to control parasites would be useful. we also sought evidence of natural immunogenic reactions among herds of chapman zebra ... | 2001 | 12790423 |
| [study on mitochondrial dna d-loop polymorphism in chinese donkeys]. | the mitochondrial dna (mtdna) d-loop sequences with 399 bp in 26 individuals from 5 donkey breeds in china were analyzed. aligned by clustal w software,the results showed that 23 polymorphic nucleotide sites and only transition with the percentage of 5.76% in 399 bp were observed. in reference to mtdna d-loop sequences of european domestic donkey as a control, the average percentage of mtdna d-loop nucleotide variation in 5 chinese donkey breeds was 1.80%. the average percentages of d-loop nucle ... | 2005 | 16018258 |
| mass spectral analysis of domestic and wild equine apoa-i and a-ii: detection of unique dimeric forms of apoa-ii. | in pigs, humans, chimpanzees and probably other great apes, a cysteine at residue 6 enables apolipoprotein a-ii to form a homodimer. however, the apoa-iis of other primates, lacking a cysteine residue, are monomeric. we have already reported that horse apoa-iis form homodimers due also to a cysteine at residue 6. in this study, we wanted to determine whether other equine apoa-iis might be monomeric. the high density lipoproteins were ultracentrifugally isolated from the plasmas of a horse (equus ... | 2005 | 16230041 |
| [african origin of chinese domestic donkeys]. | analysis of the 367 mtdna d-loop sequences (of which 241 sequences were collected from literature) of 399 bp in 13 chinese domestic donkey breeds revealed 96 different haplotypes with 57 polymorphic sites. the haplotype diversity and the nucleotide diversity were 0.767-0.967 and 0.014-0.032, respectively, indicating abundant genetic diversity in chinese domestic donkeys. the neighbor-joining tree of chinese domestic donkey sequences was constructed with 3 nubian wild ass sequences, 3 somali wild ... | 2008 | 18332001 |
| domestication of the donkey: timing, processes, and indicators. | domestication of the donkey from the african wild ass transformed ancient transport systems in africa and asia and the organization of early cities and pastoral societies. genetic research suggests an african origin for the donkey, but pinpointing the timing and location of domestication has been challenging because donkeys are uncommon in the archaeological record and markers for early phases of animal domestication are hard to determine. we present previously undescribed evidence for the earli ... | 2008 | 18332433 |
| ancient dna from nubian and somali wild ass provides insights into donkey ancestry and domestication. | genetic data from extant donkeys (equus asinus) have revealed two distinct mitochondrial dna haplogroups, suggestive of two separate domestication events in northeast africa about 5000 years ago. without distinct phylogeographic structure in domestic donkey haplogroups and with little information on the genetic makeup of the ancestral african wild ass, however, it has been difficult to identify wild ancestors and geographical origins for the domestic mitochondrial clades. our analysis of ancient ... | 2011 | 20667880 |
| affiliative and aggressive behavior in a group of female somali wild ass (equus africanus somalicus). | we observed a group of three young female somali wild asses to develop an ethogram of social behavior in the first phase of a longer term study of social, sexual, and maternal/infant behavior. the most unexpected finding was the frequency and extent of aggressive interactions, which included charge, drive, neck wrestle, head butt, and body slam, behaviors previously reported only for males of other equid species. the overall frequency of aggressive behavior was higher than that of affiliative be ... | 2011 | 21541987 |

| genetic diversity of donkey populations from the putative centers of domestication. | donkey domestication drastically changed ancient transport systems in africa and asia, enabling overland circulation of people and goods and influencing the organization of early cities and pastoral societies. genetic studies based on mtdna have pointed to the african wild ass as the most probable ancestor of the domestic donkey, but questions regarding its center of origin remain unanswered. endeavoring to pinpoint the geographical origin of domestic donkey, we assessed levels and patterns of g ... | 2015 | 25516010 |
| ancient dna provides new insight into the maternal lineages and domestication of chinese donkeys. | the donkey (equus asinus) is an important domestic animal that provides a reliable source of protein and method of transportation for many human populations. however, the process of domestication and the dispersal routes of the chinese donkey are still unclear, as donkey remains are sparse in the archaeological record and often confused with horse remains. to explore the maternal origins and dispersal route of chinese donkeys, both mitochondrial dna d-loop and cytochrome b gene fragments of 21 s ... | 2014 | 25433485 |
| de novo assembly of the donkey white blood cell transcriptome and a comparative analysis of phenotype-associated genes between donkeys and horses. | prior to the mechanization of agriculture and labor-intensive tasks, humans used donkeys (equus africanus asinus) for farm work and packing. however, as mechanization increased, donkeys have been increasingly raised for meat, milk, and fur in china. to maintain the development of the donkey industry, breeding programs should focus on traits related to these new uses. compared to conventional marker-assisted breeding plans, genome- and transcriptome-based selection methods are more efficient and ... | 2015 | 26208029 |
| pathology of gastric lesions in donkeys: a preliminary study. | donkeys (equus africanus asinus) are important working animals, particularly in countries where the majority of the population lives below the poverty line. gastric ulceration has been shown to be common in british donkeys but donkeys from other parts of the world have not been as extensively researched. | 2015 | 25138464 |
