microbiological survey of mice (mus musculus) purchased from commercial pet shops in kanagawa and tokyo, japan.information regarding the prevalence of infectious agents in mice in pet shops in japan is scarce. this information is particularly useful for minimizing the risk of potential transmission of infections to laboratory mice. therefore, we surveyed infectious agents in mice from pet shops in kanagawa and tokyo, japan. the survey was conducted in 28 mice from 5 pet shops to screen for 47 items (17 viruses, 22 bacteria and fungi, 10 parasites) using culture tests, serology, pcr, and microscopy. the m ...201425502736
hematopoietic changes and altered reactivity to il-17 in syphacia obvelata-infected mice.pinworm parasites commonly infect laboratory mice with high prevalence even in well-managed animal colonies. although often considered as irrelevant, these parasites if undetected may significantly interfere with the experimental settings and alter the interpretation of final results. there are a few reports documenting the effects of pinworms on research and the effects of pinworms on the host hematopoiesis have not yet been investigated. in this study we examined the changes within various hem ...200616325460
efficacy of selamectin against mites (myobia musculi, mycoptes musculinus and radfordia ensifera) and nematodes (aspiculuris tetraptera and syphacia obvelata) in mice.the effects of selamectin were studied in mice naturally infected with the mites myobia musculi, myoceptes musculinus and radfordia ensifera and with the oxyurid nematodes aspiculuris tetraptera and syphacia obvelata. the mice were divided into three treated and three control groups (n=9). selamectin in the range 10-12.4 mg/kg was applied topically to the skin in a single spot at the base of the neck in front of the scapulae. the mice of treated and control groups were necropsied on the 4th, 7th ...200616600081
antihelminthic activity of some newly synthesized 5(6)-(un)substituted-1h-benzimidazol-2-ylthioacetylpiperazine derivatives.piperazine derivatives of 5(6)-substituted-(1h-benzimidazol-2-ylthio)acetic acids were synthesized by using two methods and studied for antihelminthic activity. the antiparasitic screening showed that compounds 18-24 exhibited higher activity against trichinella spiralis in vitro in comparison to methyl 5-(propylthio)-1h-benzimidazol-2-yl-carbamate (albendazole). most active were compounds 2-({2-[4-(4-chlorophenyl)piperazin-1-yl]-2-oxoethyl}thio)-1h-benzimidazole 21 and 2-{[2-oxo-2-(4-benzhydryl ...200616996654

decontamination of a barrier facility using microisolator cages and provisional 2000, the authors found endemic infections of mouse hepatitis virus, minute virus of mice, syphacia obvelata, and myobia musculi among mice in a large barrier facility at the university of mainz. to eliminate the infections, they subdivided the facility into two distinct hygiene units. however, architectural constraints made it impossible to completely separate the hvac systems of both hygiene units and to establish adequate personnel locks. to compensate for these suboptimal barrier conditio ...200717585355
sequence variability in internal transcribed spacers of nuclear ribosomal dna among isolates of the oxyurid nematodes syphacia obvelata and aspiculuris tetraptera from mice reared in laboratories in china.this study examined sequence variability in internal transcribed spacers (its) of nuclear ribosomal dna among syphacia obvelata and aspiculuris tetraptera isolates from laboratory mice from different geographical locations in china. its1, 5.8s and its2 rdna were amplified separately from adult s. obvelata and a. tetraptera individuals by polymerase chain reaction (pcr), and the amplicons were subjected to sequencing from both directions. the lengths of the sequences of its1, 5.8s and its2 rdna f ...201626693888
modulation of infection-induced inflammation and locomotive deficit and longevity in senescence-accelerated mice-prone (samp8) model by the oligomerized polyphenol oligonol.oligonol is produced from the oligomerization of polyphenols (typically proanthocyanidin from a variety of fruits such as lychees, grapes, apples, persimmons, etc.) and contains catechin-type monomers and oligomers of proanthocyanidins. the ability of oligonol to affect infection-dependent eye inflammation, locomotion and longevity in senescence-accelerated prone mice (samp8) (a model of senescence acceleration and geriatric disorders with increased oxidative stress and neuronal deficit) was inv ...200717644302

genetic variability among syphacia obvelata isolates from laboratory mice in four different geographical locations of china revealed by sequence analyses of five mitochondrial genes.syphacia obvelata is a rodent nematode with high prevalence in laboratory mice. in the present study, we examined the genetic variability of s. obvelata from naturally infected laboratory mice in four different provinces, china. five mitochondrial (mt) dna regions, namely cytochrome c oxidase subunit 1 (pcox1), cytochrome b (pcytb), large subunit ribosomal rna (prrnl) and nadh dehydrogenase subunits 1 and 5 (pnad1 and pnad5), were amplified separately from individual nematodes by pcr, and then s ...201524708136
development and characterization of multiplex panels of microsatellite markers for syphacia obvelata, a parasite of the house mouse (mus musculus), using a high throughput dna sequencing approach.syphacia obvelata is a common gastro-intestinal parasitic nematode of the house mouse (mus musculus), a prime model rodent species. investigations of the genetic structure, variability of parasite populations and other biological aspects of this host-parasite system are limited due to the lack of genetic resources for s. obvelata. to fill this gap, we developed a set of microsatellite markers for s. obvelata, using a 454 pyrosequencing approach. we designed three multiplex panels allowing genoty ...201222820294
parasitic nematodes of the genus syphacia seurat, 1916 infecting muridae in the british isles, and the peculiar case of syphacia frederici.syphacia stroma (von linstow, 1884) morgan, 1932 and syphacia frederici roman, 1945 are oxyurid nematodes that parasitize two murid rodents, apodemus sylvaticus and apodemus flavicollis, on the european mainland. only s. stroma has been recorded previously in apodemus spp. from the british isles. despite the paucity of earlier reports, we identified s. frederici in four disparate british sites, two in nottinghamshire, one each in berkshire and anglesey, wales. identification was based on their s ...201728831960
