Received: 28 January 2020; Accepted: 29 February 2020; Published: 3 March 2020 Abstract: Within last 17 years two widespread epidemics of severe acute respiratory syndrome (SARS) occurred in China, which were caused by related coronaviruses (CoVs): SARS-CoV and SARS-CoV-2. Although the origin(s) of these viruses are still unknown and their occurrences in nature are mysterious, some general patterns of their pathogenesis and epidemics are noticeable. Both viruses utilize the same receptor—angiotensin-converting enzyme 2 (ACE2)—for invading human bodies. Both epidemics occurred in cold dry winter seasons celebrated with major holidays, and started in regions where dietary consumption of wildlife is a fashion. Thus, if bats were the natural hosts of SARS-CoVs, cold temperature and low humidity in these times might provide conducive environmental conditions for prolonged viral survival in these regions concentrated with bats.

BMC Genomics 2014, 15:32 http://www.biomedcentral.com/1471-2164/15/32 RESEARCH ARTICLE Open Access Transcriptome sequencing and phylogenomic resolution within Spalacidae (Rodentia) Gong-Hua Lin1, Kun Wang2, Xiao-Gong Deng1,3, Eviatar Nevo4, Fang Zhao1, Jian-Ping Su1, Song-Chang Guo1, Tong-Zuo Zhang1* and Huabin Zhao5* Abstract Background: Subterranean mammals have been of great interest for evolutionary biologists because of their highly specialized traits for the life underground. Owing to the convergence of morphological traits and the incongruence of molecular evidence, the phylogenetic relationships among three subfamilies Myospalacinae (zokors), Spalacinae (blind mole rats) and Rhizomyinae (bamboo rats) within the family Spalacidae remain unresolved. Here, we performed de novo transcriptome sequencing of four RNA-seq libraries prepared from brain and liver tissues of a plateau zokor (Eospalax baileyi) and a hoary bamboo rat (Rhizomys pruinosus), and analyzed the transcriptome sequences alongside a published transcriptome of the Middle East blind mole rat (Spalax galili). We characterize the transcriptome assemblies of the two spalacids, and recover the phylogeny of the three subfamilies using a phylogenomic approach. Results: Approximately 50.3 million clean reads from the zokor and 140.8 million clean reads from the bamboo ratwere generated by Illumina paired-end RNA-seq technology. All clean reads were assembled into 138,872 (the zokor) and 157,167 (the bamboo rat) unigenes, which were annotated by the public databases: the Swiss-prot, Trembl, NCBI non-redundant protein (NR), NCBI nucleotide sequence (NT), Gene Ontology (GO), Cluster of Orthologous Groups (COG), and Kyoto Encyclopedia of Genes and Genomes (KEGG).

E-mail: Chongxuan Han, [email protected]; Xiaoning Nan, [email protected]. Received 24 October 2019; revised 19 February 2020; accepted 2 March 2020 Abstract. Zokor (Myospalacinae) is one of the subterranean rodents, endemic to east Asia. Due to the convergent and parallel evolution induced by its special lifestyles, the controversies in morphological classification of zokor appeared at the level of family and genus. To resolve these controversies about taxonomy and phylogeny, the phylogenetic relationships of 20 species of Muroidea and six species of zokors were studied based on complete mitochondrial genome and mitochondrial Cytb gene, respectively. Phylogeny analysis of 20 species of Muroidea indicated that the zokor belonged to the family Spalacidae, and it was closer to mole rat rather than bamboo rat. Besides, by investigating the phylogenetic relationships of six species of zokors, the status of two genera of Eospalax and Myospalax was affirmed because the two clades differentiated in phylogenetic tree represented two types of zokors, convex occiput type and flat occiput type, respectively.

  • Chapter 4 the Antiquity of Rhizomys and Independent Acquisition of Fossorial Traits in Subterranean Muroids
    Chapter 4 The Antiquity of Rhizomys and Independent Acquisition of Fossorial Traits in Subterranean Muroids LAWRENCE J. FLYNN1 ABSTRACT In parallel with the growing body of molecular data bearing on the relationships of muroids, particularly subterranean lineages, the relevant fossil record has improved to the point that its data constrain scenarios of evolution about both the timing and mode of evolution of burrowing muroids, especially bamboo rats, blind mole rats, and zokors. Morphologists have considered these groups phylogenetically distinct from each other, but the three lineages appear to be related as a monophyletic Family Spalacidae, sister taxon to all other living muroids, based on both nuclear and mitochondrial genes. Although living genera are fully subterranean, the fossil record shows that the three groups evolved burrowing characteristics independently. Bamboo rats (Rhizomyinae) have the longest fossil record, extending into the Late Oligocene, but do not show fossorial traits until the Late Miocene. Blind mole rats (Spalacinae) have a fossil record nearly that long, and its early members also lack burrowing traits. Zokors (Myospalacinae) show characteristics considered derived relative to other groups, and have a shorter fossil record. The fossil record of the Tribe Rhizomyini, living Asian bamboo rats, extends to about 10 million years ago, with early species distinct at the generic level from living Rhizomys. The oldest well- known species assignable to an extant genus is Rhizomys (Brachyrhizomys) shansius from the early Pliocene of Yushe Basin, China, north of the geographic range of modern Rhizomys.A hypothesis of close relationship of bamboo rats, blind mole rats, and zokors leads to a reevaluation of affinities of certain Asian fossil taxa and reevaluation of polarity of some features, but molecular data are not yet robust enough to clarify interrelationships of the groups.

This paper presents a case report on septicemia caused by Escherichia coli (Family Enterobacteriacea) in a large bamboo rat (Rhizomys sumatrensis). R. sumatrensis is a species of rodent belonging to the Family Spalacidae. This is a widespread species occurring in China (Yunnan), Myanmar, Vietnam, Cambodia, Thailand, Malay Peninsula and Indonesia (Sumatra) (Musser & Carleton, 2005; Smith & Xie, 2008). This nocturnal species (Smith & Xie, 2008) is found in secondary forests where it feeds on bamboo roots, cultivated tapioca and sugar cane (Corbet & Hill, 1992). E. coli is a gram-negative, facultatively anaerobic, rod-shaped bacterium, and are about 2.0 micrometres (μm) long and 0.25–1.0 μm in diameter. Septicemia is a systemic disease associated with the presence, multiplication and persistence of pathogenic microorganism and their toxin in the blood.

The question of whether the same holds for teeth, however, remains unanswered. We might expect species with ever-growing dentitions to alter enamel histology in response to diet. In this study we fed bamboo rats (Rhizomys sinensis) different foods to assess effects on enamel microstructure. Results indicate that gnawing fracture-resistant items (i.e., bamboo) produces substantively different dental microstructures than does eating less mechanically-challenging ones (i.e., potato). Bamboo induces a structured, anisotropic pattern of rods that strengthens incisor enamel, whereas potato produces less structured, weaker enamel. Blood tests suggest that these differences are not related to nutrient variation. Rather, these ever-growing teeth evidently require a specific mechanical environment to develop normal dental microstructure. & 2015 Southwest Jiaotong University.

  • On the Subspecies of Rhizomys Sumatrensis (Raffles) with Some Notes on Related Species
    ON THE SUBSPECIES OF RHIZOMYS SUMATRENSIS (RAFFLES) WITH SOME NOTES ON RELATED SPECIES by Dr L. D. BRONGERSMA Rijksmuseum van Natuurlijke Historie, Leiden With 4. textfigures The present paper, chiefly dealing with Rhizomys sumatrensis (Raffl.), is based on the examination of a series of specimens in the collections of the Rijksmuseum van Natuurlijke Historie, Leiden; Zoologisch Museum, Amsterdam; British Museum (Natural History), London; Museum d'Histoire Naturelle, Geneve; Naturhistorisches Museum, Bern and the Collection of Mr. H. J. V. Sody, Amsterdam. To the following gentlemen I am indebted for the permission to study the specimens under their care: Prof. Dr F. Baumann and Dr W. Kiienzi, Bern; Mr. A. C. V. van Bemmel, Amsterdam; Dr M. A. C. Hinton and Mr. R. W. Hayman, London; Dr G. C. A. Junge, Leiden; Prof. Dr P. Revilliod, Geneve; Mr. H. J. V. Sody, Amsterdam. To Mr. M. A. Koekkoek, Rijksmuseum van Natuurlijke Historie, Leiden, my thanks are due for the carefully prepared drawings (textfigs. 1—4). For some unknown reason Raffles (1822, p. 258) gave the name Mus sumatrensis to a rodent, which was known from Malacca, but which at the time had not yet been recorded from Sumatra1). Temminck (1832, p. 7, pi. 1), who thought the name inappropriate, redescribed the species as 1) In the older literature the species has been mentioned from Sumatra by several authors, e.g., Lesson (1827, p. 265), Schlegel (1837, p. 235), M'Clelland (1842: fide Cantor 1846, p. 255), Murray (1866, p. 383), W. H. Flower & Garson (1884, p. 612), but they were probably misled by the name sumatrensis.

  • Giardia Duodenalis Infection in Bamboo Rats Xun Ma†, Yi Wang†, Hui-Jun Zhang, Hao-Xian Wu and Guang-Hui Zhao*
    Ma et al. Parasites & Vectors (2018) 11:520 https://doi.org/10.1186/s13071-018-3111-2 SHORTREPORT Open Access First report of Giardia duodenalis infection in bamboo rats Xun Ma†, Yi Wang†, Hui-Jun Zhang, Hao-Xian Wu and Guang-Hui Zhao* Abstract Background: The zoonotic parasite, Giardia duodenalis (syns. G. lamblia and G. intestinalis), has been widely reported in humans and animals, including rodents. The bamboo rat, a rodent species belonged to the subfamily Rhizomyinae, is farmed in China because of its medicinal and edible values. However, no information of G. duodenalis infection was available in bamboo rats prior to the present study. Here, the prevalence and genetic diversity of G. duodenalis in bamboo rats from Hunan Province of China were investigated. Results: Of 480 faecal samples collected from six farms located in four cities (Wugang, Chenzhou, Huaihua and Jishou) of Hunan Province, 52 (10.8%) were positive for G. duodenalis infection by using a nested PCR approach targeting the beta giardin (bg) gene. Significant differences (P < 0.01) in prevalence were found among different age groups and geographical localities, and among different farms in Wugang city. Sequence analysis revealed existence of the zoonotic assemblage B and genetic diversity of G. duodenalis in these animals. Multilocus genotyping analysis also indicated broad genetic diversity of assemblage B isolates in these bamboo rats. Conclusions: This is the first report of the infection and genetic variations of G. duodenalis in bamboo rats. These findings will provide basic data for implementing effective strategies to control giardiasis in bamboo rats. Keywords: Giardia duodenalis, Prevalence, Bamboo rat, Hunan Province Background or immunocomprised individuals [24, 25].

Conventional stain- ing, GTG-, CBG-, and Ag-NOR banding, and high-resolution analysis were carried out on standard whole blood T-lymphocyte cultures from six specimens of R. pruinosus from three localities. The re- sults showed that 2n=50 and the fundamental number is 100 in both sexes. The autosomes consisted of 12 large acrocentric, 4 medium submetacentric, 6 medium acrocentric, 6 small metacentric, and 20 small acrocentric chromosomes. The X chromosome is the largest metacentric chromosome, while the Y chromosome is a small acrocentric chromosome. A multiple sex chromosome system of the X1Y,X2Y/X1X2 type was found in R. pruinosus, which is the first description in the subfamily Rhizomyinae. From GTG-banding and high-resolution techniques, the numbers of bands and loca- tions in R. pruinosus are determined to be 234 and 280, respectively, and each chromosome pair could be clearly differentiated.
