Rodents, both commensal and wild, serve as reservoirs for a variety of diseases in nature communicable to man. Forty-six percent of the 30 human plague cases in the past two decades in California are associated with campgrounds and public use recreational sites. In addition, human cases of tularemia, giardiasis, relapsing fever, Rocky Mountain spotted fever, Colorado tick fever, and Lyme diseas...

abstract rodent have global spread and include the largest order of mammals that their broad range of adaptation is extensive. so far don’t perform a study on rodent fauna of ferdows county. therefore, the aim of this study is to identify this part of the vertebrates in this area. in this regard in order to identification and biosystematics survey of rodent fauna from winter 2014 to june 2014 i...

during a search of burrows for the purpose of capturing rodents in 1972, a number of soil samples were inspected for the collection of sand fly larvae. in this study, a total of 472 plastic bags of soil samples were collected from different depths of 30 rodent burrows. fourteen of these samples were found positive, from which 27 larvae were removed. most of the larvae were found in the depths o...

To clarify how Borrelia miyamotoi is maintained in the environment in Hokkaido, we examined Ixodes persulcatus for its prevalence among wild rodents and its tick vector by detecting a portion of the borrelial flaB gene in rodent urinary bladder and blood samples, and from whole ticks. We compared B. miyamotoi infection rates to Borrelia garinii and Borrelia afzelii, which are human Lyme disease...

In this study we examine the size of primary sensory areas in the neocortex and the cellular composition of area 17/V1 in three rodent groups: laboratory nocturnal Norway rats (Long-Evans; Rattus norvegicus), wild-caught nocturnal Norway rats (R. norvegicus), and laboratory diurnal Nile grass rats (Arvicanthis niloticus). Specifically, we used areal measures of myeloarchitecture of the primary ...

background: zoonotic cutaneous leishmaniasis (zcl) is a neglected disease with public health importance that is common in many rural areas of iran. in recent years, behavioral resistance and/or bait shyness against the common rodenticide among reservoir hosts of zcl have been reported. the aim of this study was to evaluate the effectiveness of klerat® and zinc phosphide against natural reservoi...

UNLABELLED Hepatitis C virus (HCV) and human pegivirus (HPgV or GB virus C) are globally distributed and infect 2 to 5% of the human population. The lack of tractable-animal models for these viruses, in particular for HCV, has hampered the study of infection, transmission, virulence, immunity, and pathogenesis. To address this challenge, we searched for homologous viruses in small mammals, incl...

Background: Chlamydia (C.) trachomatis is an obligate intracellular gram-negative pathogen affecting over 600 million people worldwide with 92 million new cases occurring globally each year. Genital C. trachomatis infection has been recognized as the most common cause of pelvic inflammatory disease leading to severe tubal damage, ectopic pregnancy, hydrosalpinx and infertility. However, the mec...

Small mammals are found naturally infected by Schistosoma mansoni, becoming a confounding factor for control programs of schistosomiasis in endemic areas. The aims of this study were: to investigate the infection rates by S. mansoni on the water-rat Nectomys squamipes during four years in endemic areas of Sumidouro, state of Rio de Janeiro, using mark-recapture technique; to compare two diagnos...

Rodent mandibular incisors have a unique anatomical structure that allows teeth to grow throughout the lifetime of the rodent. This report presents a novel transplantation technique for studying the apical bud differentiation of rodent mandibular incisors. Incisal apical end tissue with green fluorescent protein from transgenic mouse was transplanted to wild type mice, and the development of th...
