| ultrastructure of major intraglandular ducts in the parotid gland of the african mole-rat. | the parotid gland of a female african mole-rat, tachyoryctes splendens, was examined by light and electron microscopy. a pure seromucous gland of conventional histology, its striated and excretory ducts contain prominent cytoplasmic inclusions that are lightly stained with toluidine blue. at the ultrastructural level, the inclusions are seen to consist of a light to moderately dense structureless matrix in which are suspended scattered, randomly oriented filaments that either are 4-7 nm or appro ... | 1998 | 9825888 |
| infectivity, pathogenicity, and genetic characteristics of mammalian gastric cryptosporidium spp. in domestic ruminants. | farm ruminants were infected experimentally with four mammalian gastric cryptosporidium, namely cryptosporidium andersoni li03 originated from cattle and three isolates of cryptosporidium muris from brown rat (isolate rn66), bactrian camel (isolate cb03) and firstly characterized isolate from east african mole rat (isolate ts03). sequence characterizations of the small-subunit rrna gene showed that the li03 isolate was c. andersoni and the other three isolates belonged to c. muris, although the ... | 2008 | 18343038 |
| nucleotide sequences of b1 sine and 4.5s(i) rna support a close relationship of zokors to blind mole rats (spalacinae) and bamboo rats (rhizomyinae). | until recently, zokors (myospalacinae) were assigned to the cricetidae family. however, analysis of mitochondrial and nuclear genes suggests a sister relationship between zokors and subterranean rodents of the spalacidae family, namely blind mole rats (spalacinae) and bamboo rats (rhizomyinae). here, we cloned and sequenced copies of the b1 short interspersed element (sine) from the genome of zokor myospalax psilurus. the consensus nucleotide sequence of zokor b1 was very similar to spalacids an ... | 2010 | 20399257 |
| development of a multilocus sequence tool for typing cryptosporidium muris and cryptosporidium andersoni. | although widely used for the characterization of the transmission of intestinal cryptosporidium spp., genotyping tools are not available for c. muris and c. andersoni, two of the most common gastric cryptosporidium spp. infecting mammals. in this study, we screened the c. muris whole-genome sequencing data for microsatellite and minisatellite sequences. among the 13 potential loci (6 microsatellite and 7 minisatellite loci) evaluated by pcr and dna sequencing, 4 were eventually chosen. dna seque ... | 2010 | 20980577 |
| cryptosporidium proliferans n. sp. (apicomplexa: cryptosporidiidae): molecular and biological evidence of cryptic species within gastric cryptosporidium of mammals. | the morphological, biological, and molecular characteristics of cryptosporidium muris strain ts03 are described, and the species name cryptosporidium proliferans n. sp. is proposed. cryptosporidium proliferans obtained from a naturally infected east african mole rat (tachyoryctes splendens) in kenya was propagated under laboratory conditions in rodents (scid mice and southern multimammate mice, mastomys coucha) and used in experiments to examine oocyst morphology and transmission. dna from the p ... | 2016 | 26771460 |
| comparative gastrointestinal morphology of tachyoryctes splendens (rüppell, 1835) and heliophobius emini, (noack, 1894) two species of east african mole-rats. | tachyoryctes splendens (northeast african mole-rat) and heliophobius emini (emin's mole-rat) are two african mole-rats that represent separate allopatric rodent families namely spalacidae and bathyergidae respectively. while these species consume a similar diet of underground plant storage organs such as roots and tubers, t. splendens has been reported to additionally consume small amounts of aerial foliage. this study aims to provide detailed gross morphological and histological morphometric an ... | 2017 | 28370359 |
| functional morphology of the olfactory mucosa and olfactory bulb in fossorial rodents: the east african root rat (tachyoryctes splendens) and the naked mole rat (heterocephalus glaber). | optimal functioning of the olfactory system is critical for survival of fossorial rodents in their subterranean lifestyle. this study examines the structure of the olfactory mucosa and olfactory bulb of two fossorial rodents exhibiting distinct social behaviors, the east african root rat and the naked mole rat. the social naked mole rat displayed simpler ethmoturbinates consisting of dorsomedial and broad discoid/flaplike parts that projected rostrally from the ethmoid bone. in the solitary root ... | 2017 | 28780992 |
| mima mounds in the kenya highlands: significance for the dalquest-scheffer hypothesis. | the dalquest-scheffer hypothesis that mima mounds in western north america are the long-term product of burrowing activities of geomyid pocket gophers was tested by examination of areas of similar topography in the highlands of kenya. two mound areas, located near nyahururu at an elevation of about 2,400 m, were studied in detail. the mounds ranged from less than 25 cm to 2 m in height and from a few m to about 20 m in diameter, and were not the remains of large termite nests. populations of the ... | 1983 | 28310172 |
| ethiopian highlands as a cradle of the african fossorial root-rats (genus tachyoryctes), the genetic evidence. | root-rats of the genus tachyoryctes (spalacidae) are subterranean herbivores occupying open humid habitats in the highlands of eastern africa. there is strong disagreement about species diversity of the genus, because some authors accept two species, while others more than ten. species with relatively high surface activity, the giant root-rat tachyoryctes macrocephalus, which is by far largest member of the genus, and the more fossorial african root-rat tachyoryctes splendens, which eventually h ... | 2018 | 29626665 |
