R-spondins constitute a recently discovered small family of growth factors, and the evidence of their role in several developmental pathways is growing fast. In this work we describe the chromosomal location of the four RSPO genes in the donkey. Using horse BACs, we localized RSIPO1 on EAS 5q23, RSPO2 on EAS 12q13, RSPO3 on EAS 24q26, and RSPO4 on EAS 15p13. Moreover, RSPO2, RSPO3, and RSPO4 are the first genes mapped on donkey chromosomes 12, 24, and 15, respectively.
The endoparasites of horses and donkeys of different ages from the Konya region in Turkey, between May 2003 and June 2005 were determined. The samples of fresh faeces were collected from 111 horses and 81 donkeys and sent to diagnostic laboratories for the examination by floatation, sedimentation, and Baermann-Wetzel methods. In addition, faecal cultures were prepared for the differentiation of larvae of Strongylidae. Parasites were encountered in 100% of horses and donkeys. Among the parasites determined in horses, the prevalence of Strongylidae, Parascaris equorum, Strongyloides westeri, Fasciola sp., Anoplocephalidae, Oxyuris equi, Trichuris sp., Dicrocoelium dendriticum, Eimeria leucarti, and Eimeria sp. was 100%, 10.81%, 7.2%, 3.6%, 2.7%, 1.8%, 0.9%, 0.9%, 4.5%, and 12.61%, respectively. In donkeys, the prevalence of Strongylidae, S. westeri, P. equorum, Fasciola sp., Anoplocephalidae, Oxyuris equi, Dicrocoelium dendriticum, Eimeria leucarti, and other Eimeria sp. was 100%, 12.34%, 9.8%, 6.17%, 6.17%, 1.23%, 1.23%, 3.7%, and 22.22%, respectively. According to faecal cultures, the prevalence of Strongylus vulgaris, Strongylus edentatus, Trichonema sp., Triodontophorus sp., and Poteriostomum sp. was 31.53%, 17.11%, 58.55%, 6.3%, and 5.40% in horses, respectively, and 23.45%, 14.81%, 74.07%, 4.93%, and 2.46% in donkeys, respectively.
The study investigated the anatomy of the arteries of the brain in seven donkeys following intravascular injection of colored latex via the a. vertebralis and a. carotis communis. Arterial blood washed the brain via the bilateral a. carotis interna and a. vertebralis and via the unpaired a. basilaris. A. carotis interna entered the cavum cranii at the level of sulcus pontocruralis, and ramified at the level of the corpus mamillare into a. cerebri rostralis and a. communicans caudalis. At the level intracranial entry, a. carotis interna gave rice to a. caroticobasillaris which was bilaterally present in 4 cases and unilaterally in 1 animal, a. caroticobasillaris, whereas the other branch was and a. constant a. intercarotica caudalis which was located at the level of sulcus pontocruralis. In one cadaver, a very slender a. intercarotica rostralis originated from a. carotis interna at the level of the origin of a. cerebri rostralis, and joined its counterpart vessel at the border between tuber cinereum and chiasma opticum. In all cases, a. ethmoidalis interna originated from a. cerebri rostralis. It was observed that a. cerebri rostralis dextra et sinistra fused directly into a. single median vessel named a. communicans rostralis.
Thirty-four donkeys from Henan Province, China, were examined at necropsy for strongyloid nematodes in the caecum (February 2006 to January 2007). Twenty-two species, including 18 Cyathostominae (small strongyles) and 4 Strongylinae (large strongyles), were identified. The five most prevalent Cyathostominae were Cylicocyclus nassatus (73.5%), Coronocyclus labratus (70.6%), Coronocyclus labiatus (67.6%), Cyathostomum tetracanthum (61.8%) and Coronocyclus coronatus (52.9%), accounting for 70.2% of all species identified; C. labratus (124.2 ± 256.4), Cyathostomum tetracanthum (96.4 ± 210.5) and Cylicocyclus nassatus (80.9 ± 117.1) had the greatest mean abundance, whereas Strongylus vulgaris was the most prevalent (88.2%) of the Strongylinae and had the highest mean abundance (34.9 ± 37.8). The numbers of species per donkey ranged from 1 to 15 (with a median of 7.1). Only a small percentage (5.9%) of donkeys were infected by a single species, whereas the other donkeys had infections with multiple species.
