The emerging tick-borne pathogen Anaplasma phagocytophilum is under increasing scrutiny for the existence of subpopulations that are adapted to different natural cycles. Here, we characterized the diversity of A. phagocytophilum genotypes circulating in a natural system that includes multiple hosts and at least 2 tick species, Ixodes ricinus and the small mammal specialist I. trianguliceps. We ...
Habitat fragmentation commonly influences distribution of zoonotic disease reservoirs. In Panama, populations of rodent hosts of hantaviruses are favored by small habitat fragments isolated by agricultural lands. We expected a similar relationship between landscape characteristics and host distribution at fine geographical scales in southern Panama. The relative abundance of Zygodontomys brevic...
We compare and contrast the results of immunizing mice with irradiated sporozoites of Plasmodium berghei and Plasmodium yoelii. Host genetic control of protective immunity is different in the two rodent malarias. Few mouse strains are strongly protected by P. yoelii sporozoites, while all are protected by P. berghei sporozoite immunization. The role of CD8+ T cells in the protective immune resp...
In an effort to understand what limits the virulence of malaria parasites, we infected inbred mice of three genotypes (C57Bl/6J, CBA/Ca and DBA/2) with one of two parasite lines of the rodent malaria Plasmodium chabaudi. One of these parasite lines had been serially passaged through C57Bl/6J mice and had evolved higher asexual growth rate, virulence and transmission in the process. The other pa...
Abstract This checklist of parasites Kerodon rupestris, an endemic rodent from the Brazilian semiarid region, revealed records 25 enteroparasite taxa comprising Cestoda (Anoplocephalidae), Trematoda, Acanthocephala and Nematoda (Ancylostomidae, Ascarididae, Heterakidae, Oxyuridae, Pharyngodonidae, Trichuridae, Capillariidae, Trichostrongylidae, Strongyloididae), two coccidian. Paleoparasitologi...
Due to their special environments, rural areas are susceptible to rodent outbreaks. Extensive damage to agricultural produce, equipment and buildings on the one hand and outbreaks of zoonotic diseases on the other are among the health and economic impacts of a rodent outbreak. Failure in controlling such events may even result in social issues, such as, village abandonment and mass migration to...
Rodent herpesviruses such as murine cytomegalovirus (host, Mus musculus), rat cytomegalovirus (host, Rattus norvegicus), and murine gammaherpesvirus 68 (hosts, Apodemus species) are important tools for the experimental study of human herpesvirus diseases. However, alphaherpesviruses, roseoloviruses, and lymphocryptoviruses, as well as rhadinoviruses, that naturally infect Mus musculus (house mo...
leishmania infantum, an etiologic agent of zoonotic visceral leishmaniasis (vl), is spreading in iran. dogs are the main reservoirs but l.infantum has been detected in jackals, foxes and wild rodents too. despite high number of rodents in the world, the exact role of them in epidemiology of vl is not clear. in recent years the number of sporadic cases of dogs and humans vl has been increased in...
background: to determine the prevalence and intensity of helminths and their zoonotic importance in small rodents inhabiting in the suburban areas of hamadan city,iran. methods: the present survey was conducted on the helminth infections of two species of rodents apodemus sylvaticus (n=60) and mus musculus (n=72) in the suburban areas of hamadan city during 2010-2012. rodents were collected and...
