zoonotic gastrointestinal helminths in rodent communities in southern guatemala.rodents are reservoirs and hosts of several pathogens around the world, including zoonotic parasite species. this study aimed to determine the occurrence of zoonotic gastrointestinal helminths in rodents captured inside households in a rural community from southern guatemala. sixty-nine rodents were captured in 33% (49/148) of the surveyed households, including rattus rattus, rattus norvegicus, mus musculus, and sigmodon hispidus. thirty-six percent (25/69) of these rodents (3 rattus and 22 mus ...202032227228
rapid host expansion of an introduced parasite, the spiny rat louse polyplax spinulosa (psocodea: phthiraptera: polyplacidae), among endemic rodents in australia.historical european exploration and colonization resulted in the introduction of four species of rodents to the australian continent from eurasia: the brown rat, rattus norvegicus, the black rat, r. rattus, the pacific rat, r. exulans, and the house mouse, mus musculus. the spread of these rodents created opportunities for their co-introduced sucking lice to parasitize and adapt to endemic rodents in australia.202032070404
synanthropic rodents as virus reservoirs and transmitters.this review focuses on reports of hepatitis e virus, hantavirus, rotavirus, coronavirus, and arenavirus in synanthropic rodents (rattus rattus, rattus norvegicus, and mus musculus) within urban environments. despite their potential impact on human health, relatively few studies have addressed the monitoring of these viruses in rodents. comprehensive control and preventive activities should include actions such as the elimination or reduction of rat and mouse populations, sanitary education, redu ...202032049206
genetic diversity and lack of molecular evidence for hemoplasma cross-species transmission between wild and synanthropic mammals from central-western brazil.globally, hemotropic mycoplasmas (hemoplasmas) comprise an emerging or remerging bacteria group that attaches to red blood cells of several mammal's species and in some cases, causing hemolytic anemia. herein, we assessed the occurrence, genetic diversity, the factors coupled to mammals infection, and the phylogeographic distribution of hemoplasmas in sylvatic and synanthropic mammals and their associated ectoparasites from brazil. we collected spleen and/or blood samples from synanthropic roden ...202031857081
tick-borne pathogens in dogs, wild small mammals and their ectoparasites in the semi-arid caatinga biome, northeastern brazil.caatinga is a biome exclusive to the semiarid zone of brazil, where studies on ticks and tick-borne diseases are scarce. herein, we investigated the occurrence of rickettsia, ehrlichia, and coxiella in wild mammals, domestic dogs and their ectoparasites using molecular and serological techniques. during 2014-2016, blood samples and ectoparasites were collected from 70 small mammals (51 rodents, 18 marsupials, 1 wild canid) and 147 domestic dogs in three areas of the caatinga. through serological ...202032111546
structural analysis of covid-19 spike protein in recognizing the ace2 receptor of different mammalian species and its susceptibility to viral infection.the pandemic covid-19 was caused by a novel coronavirus-2 (sars-cov-2) that infects humans through the binding of glycosylated sars-cov-2 spike 2 protein to the glycosylated ace2 receptor. the spike 2 protein recognizes the n-terminal helices of the glycosylated metalloprotease domain in the human ace2 receptor. to understand the susceptibility of animals for infection and transmission, we did sequence and structure-based molecular interaction analysis of 16 ace2 receptors from different mammali ...202133552834
social distancing measures differentially affected rats in north america and tokyo.because rats are commensal organisms that depend on human activities for food, shifts in human behavior will have pronounced effects on local rat populations. in the spring of 2020, social distancing measures were implemented globally to curtail the spread of sars-cov-2. this presented a unique opportunity to obtain information regarding the immediate effects of shifts in human behavior on rat populations in a variety of countries. in response to increased sightings of rats in the usa that were ...202134248453
complete genome sequences of two rat pegivirus strains in indonesia.the entire genome sequences of two pegivirus strains recovered from serum samples of wild rats (rattus rattus) in indonesia were determined. they possessed 11,013 to 11,014 nucleotides and differed from the reported rodent pegivirus strains within the pegivirus j species of the genus pegivirus by 12.7% to 40.9% in the near-entire coding region sequences.202133737352
rodent-borne orthohantaviruses in vietnam, madagascar and japan.hantaviruses are harbored by multiple small mammal species in asia, europe, africa, and the americas. to ascertain the geographic distribution and virus-host relationships of rodent-borne hantaviruses in japan, vietnam, myanmar, and madagascar, rnalater™-preserved lung tissues of 981 rodents representing 40 species, collected in 2011-2017, were analyzed for hantavirus rna by rt-pcr. our data showed hantaan orthohantavirus da bie shan strain in the chinese white-bellied rat (niviventer confucianu ...202134372549
black rats (rattus rattus) as potential reservoir hosts for rift valley fever phlebovirus: experimental infection results in viral replication and shedding without clinical manifestation.rift valley fever phlebovirus (rvfv) is an arthropod-borne virus that can cause severe disease in ruminants and humans. epidemics occur mainly after heavy rainfall, which leads to a significant increase in the occurrence of rvfv-transmitting mosquitoes. during inter-epidemic periods, the virus is assumed to be maintained between mosquitoes, susceptible livestock and yet unknown wildlife. the widespread rodent rattus rattus (black rat) has been suspected to be involved in rvfv maintenance. in ord ...202133794070
