| invasive rats strengthen predation pressure on bird eggs in a south pacific island rainforest. | invasive rats (rattus spp.) are known to have pervasive impacts on island birds, particularly on their nesting success. to conserve or restore bird populations, numerous invasive rat control or eradication projects are undertaken on islands worldwide. however, such projects represent a huge investment and the decision-making process requires proper assessment of rat impacts. here, we assessed the influence of two sympatric invasive rats (rattus rattus and r. exulans) on native bird eggs in a new ... | 2017 | 29492018 |
| predicting reintroduction outcomes for highly vulnerable species that do not currently coexist with their key threats. | predicting reintroduction outcomes before populations are released is inherently challenging. it becomes even more difficult when the species being considered for reintroduction no longer coexists with the key threats limiting its distribution. however, data from other species facing the same threats can be used to make predictions under these circumstances. we used an integrated bayesian modeling approach to predict growth of a reintroduced population at a range of predator densities when no da ... | 2018 | 29455467 |
| investigations into the role of rats as intermediate hosts for neospora caninum in chennai, india. | attempts were made to detect neospora caninum in rats (rattus rattus) in and around chennai, india. during the study, 112 feral rats were trapped and blood, brain, heart, lungs and diaphragm samples were collected for serological, parasitological and molecular identification of n. caninum. out of 112 rats, cyst-like structures were identified in 16 brain squash samples. however, the identity of the cysts could not be confirmed as n. caninum. a total of 12 sera samples were positive for n. caninu ... | 2017 | 31014654 |
| [(acari: trombiculidae) (the infestation of small mammals in south-eastern vietnam with harvest mites (acari: trombiculidae))]. | this investigation was conducted in three provinces of southern vietnam in september-october 2011. a total of 257 small mammals of 11 species were caught; among them 120 rodents were infected with harvest mites of 8 species (trom- biculidac). about 4000 mites of nearly 1200 identified species were collected from the small mammals. 17 species of harvest mites were identified. walchia lupella, leptotrombidium deliense, walchia kritochaeta, and walchia micropelta predominated in the collections. mo ... | 2017 | 30721614 |
| 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 ... | 2021 | 33552834 |
| 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 ... | 2021 | 34248453 |
| 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. | 2021 | 33737352 |
| 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 ... | 2021 | 34372549 |
| 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 ... | 2021 | 33794070 |
| molecular characterization of encephalomyocarditis virus strains isolated from an african elephant and rats in a french zoo. | in november 2013, a fatal encephalomyocarditis virus (emcv) case in a captive african elephant (loxodonta africana) occurred at the réserve africaine de sigean, a zoo in the south of france. here we report the molecular characterization of the emcv strains isolated from samples collected from the dead elephant and from 3 rats (rattus rattus) captured in the zoo at the same time. the emcv infection was confirmed by reverse-transcription real-time pcr (rt-rtpcr) and genome sequencing. complete gen ... | 2020 | 33292091 |
