From the Spiny Mouse, Acomys Dimidiatus, in Saudi Arabia J. Helminthol. Soc. Wash. 60(1), 1993, pp. 14-21 Dentostomella tamimi sp. n. (Nematoda: Heteroxynematidae) from the Spiny Mouse, Acomys dimidiatus, in Saudi Arabia H. S. HUSSEIN AND A. M. N. KALANTAN Department of Zoology, College of Science, King Saud University, P.O. Box 2455, Riyadh 11451, Saudi Arabia ABSTRACT: Dentostomella tamimi sp. n. was collected from the anterior third of the small intestine of the spiny mouse, Acomys dimidiatus (Cretzschmar, 1826), trapped at Hotut Beni Tamim and at Heet, Riyadh Province, Saudi Arabia. The worms are long and slender and have the largest cervical inflation in the genus Dentostomella. On top of this inflation, there are 4 large submedian papillae, 2 on either side, together with 2 lateral amphids, on either side between the submedian papillae. Three pairs of small, hardly discernible papillae surround the small, circular mouth opening, 1 pair dorsally and 2 pairs ventrally. The mouth opens into a shallow, triradiate buccal cavity surrounded by 3 esophageal sectors. Each sector has 2 small lateral teeth and a single, large median tooth. Females are 21.0-25.0 (22.5) mm long, 0.49-0.55 (0.52) mm wide, at the region of the vulva, which is located at about the middle of the body. Males are 14.0-16.0 (15.4) mm long and of a maximum width of 0.34- 0.38 (0.354) mm. The male has a median rugose and fleshy bursa without supporting rays, and its tail bears 7 caudal papillae, 1 pair preanal, 1 pair adanal, an unpaired papilla just under the cloaca, and 1 pair subanal. The single male spicule is lightly sclerotized, with an irregular depression on its anterior end; its distal tip is bifid in ventral view. The tip of the tail in both sexes has an arrowhead appearance dorsoventrally and is more pronounced in males. This is due to the presence of 2 small, ventrolateral protuberances containing the phasmids.

  • Monkeys, Mice and Menses: the Bloody Anomaly of the Spiny Mouse
    Journal of Assisted Reproduction and Genetics (2019) 36:811–817 https://doi.org/10.1007/s10815-018-1390-3 COMMENTARY Monkeys, mice and menses: the bloody anomaly of the spiny mouse Nadia Bellofiore1,2 & Jemma Evans3 Received: 18 November 2018 /Accepted: 17 December 2018 /Published online: 5 January 2019 # Springer Science+Business Media, LLC, part of Springer Nature 2019 Abstract The common spiny mouse (Acomys cahirinus) is the only known rodent to demonstrate a myriad of physiological processes unseen in their murid relatives. The most recently discovered of these uncharacteristic traits: spontaneous decidual transformation of the uterus in virgin females, preceding menstruation. Menstruation occurring without experimental intervention in rodents has not been documented elsewhere to date, and natural menstruation is indeed rare in the animal kingdom outside of higher order primates. This review briefly summarises the current knowledge of spiny mouse biology and taxonomy, and explores their endocrinology which may aid in our understanding of the evolution of menstruation in this species. We propose that DHEA, synthesised by the spiny mouse (but not other rodents), humans and other menstruating primates, is integral in spontaneous decidualisation and therefore menstruation. We discuss both physiological and behavioural attributes across the menstrual cycle in the spiny mouse analogous to those observed in other menstruating species, including premenstrual syndrome. We further encourage the use of the spiny mouse as a small animal model of menstruation and female reproductive biology. Keywords Menstruation . Novel model .

It is also known that organism for regeneration studies. For a mammal, it displays several individual mammalian tissues can regenerate, such as surprising powers of regeneration because it does not fibrose (i.e. skeletal muscle after myotoxin administration (Musarò, 2014) and scar) in response to tissue injury as most other mammals, including the liver, which displays prodigious powers of proliferation during humans, do. In this Primer article, we review these regenerative compensatory hypertrophy (Fausto et al., 2012). This compensatory abilities, highlighting the phylogenetic position of the spiny mouse hypertrophy is a process which the lungs can also undergo (Hsia, relative to other rodents. We also briefly describe the Acomys tissues 2017), whereby the tissue remaining after removal of part of the that have been used for regeneration studies and the common organ expands to compensate for the missing part. Many features of their regeneration compared with the typical mammalian mammalian epithelial tissues, such as the epidermis or the response. Finally, we discuss the contribution that Acomys has made intestinal lining, also exhibit continuous replacement, although in understanding the general principles of regeneration and elaborate this is a property of all animals and so is not considered an unusual hypotheses as to why this mammal is successful at regenerating.

Fourteen other valid species of Moniliformis Travassos, 1915 are recognised. The new species of Moniliformis is distinguished by having a small proboscis (315–520 µm long and 130–208 µm wide) with two apical pores, 14 rows of 8 hooks each and small hooks, thre largest being 25–31 µm long anteriorly. Distinguishing features are incorporated in a dichotomous key to the species of Moniliformis. The description is augmented by scanning electron microscopical (SEM) observation and DNA analysis of nuclear (18S rRNA) and mitochondrial (cytochrome oxidase subunit 1; cox1) gene sequences. Attached worms cause ex- tensive damage to the immediate area of attachment in the host intestine. This includes tissue necrosis and blood loss due to damage to capillary beds. Worms also obstruct essential absorbing surfaces.

This study assesses the systematic and geographic distribution of Acomys from northern Tanzania using a multidisciplinary approach that includes molecular, cytogenetic, traditional and geometric morphometric analyses, and classical morphology of the same individuals. The molecular analysis was based on 1140 base pairs (bp) of the mitochondrial cytochrome b and 1297 bp of the nuclear interphotoreceptor retinoid binding protein (IRBP) gene sequences. These data were subjected to phylogenetic analyses using Maximum likelihood, Bayesian, Maximum parsimony, and Minimum evolution analyses. The cytogenetic analysis included G-banding of metaphase chromosomes.
