| 1 | Rodent control to fight plague:field assessment of methods based on rat density reduction显示文摘Rodents represent a serious threat to food security and public health.The extent to which rodent control can mitigate the risk from rodent-borne disease depends on both the effectiveness of control in reducing rodent abundance and the impact on disease epidemiology.Focusing on a plague-endemic region of Madagascar,this study compared the effectiveness of 3 methods:live-traps,snap-traps,and rodenticides.Control interventions were implemented inside houses between May and October 2019.Tracking tiles monitored rodent abundance.Rodent fleas,the vector involved in plague transmission,were collected.Rodent populations consisted of Rattus rattus and Mus musculus.In terms of trap success,we found that our live-trap regime was more effective than snap-traps.While all 3 control strategies appeared to reduce in-house rodent activity in the short term,we found no evidence of a longer-term effect,with in-house rodent abundance in treated sites comparable to non-treatment sites by the following month.Endemic flea,Synopsyllus fonquerniei,is a key plague vector usually found on rats living outdoors.Although we found no evidence that its abundance inside houses increased following control,this may have been due to a lack of power caused by significant variation in S.fonquerniei abundance.The presence of S.fonquerniei in houses was more likely when S.fonquerniei abundance on outdoor rats was higher,which in turn correlated with high rat abundance.Our results emphasize that control strategies need to consider this connectivity between in-house rat–flea populations and the outdoor populations,and any potential consequences for plague transmission. | Soanandrasana RAHELINIRINA Kathryn SCOBIE Beza RAMASINDRAZANA Voahangy ANDRIANAIVOARIMANANA Fanohinjanaharinirina RASOAMALALA Lovasoa Nomena RANDRIANTSEHENO Jerry Sylvio RAKOTONIAINA Olivier GORGÉ Xavier LAMBIN Eric VALADE Sandra TELFER Minoarisoa RAJERISON | 2021 | Integrative Zoology2021，16，6： | 1 |
| 2 | Plague reservoir species throughout the world显示文摘Plague has been known since ancient times as a re-emerging infectious disease,causing considerable socioeconomic burden in regional hotspots.To better understand the epidemiological cycle of the causative agent of the plague,its potential occurrence,and possible future dispersion,one must carefully consider the taxonomy,distribution,and ecological requirements of reservoir-species in relation either to natural or human-driven changes(e.g.climate change or urbanization).In recent years,the depth of knowledge on species taxonomy and species composition in different landscapes has undergone a dramatic expansion,driven by modern taxonomic methods such as synthetic surveys that take into consideration morphology,genetics,and the ecological setting of captured animals to establish their species identities.Here,we consider the recent taxonomic changes of the rodent species in known plague reservoirs and detail their distribution across the world,with a particular focus on those rodents considered to be keystone host species.A complete checklist of all known plague-infectable vertebrates living in plague foci is provided as a Supporting Information table. | Ahmad MAHMOUDI Boris KRYŠTUFEK Alexander SLUDSKY Boris V.SCHMID Alzira M.P.DE ALMEIDA Xu LEI Beza RAMASINDRAZANA Eric BERTHERAT Aidyn YESZHANOV Nils ChrSTENSETH Ehsan MOSTAFAVI | 2021 | Integrative Zoology2021，16，6： | 0 |
