Human Infections withRickettsia raoultii, China

Abstract

We used molecular methods to identify Rickettsia raoultii infections in 2 persons in China. These persons had localized rashes around sites of tick bites. R. raoultii DNA was detected in 4% of Dermacentor silvarum ticks collected in the same area of China and in 1 feeding tick detached from 1 patient.

Landscape of emerging and re-emerging infectious diseases in China: impact of ecology, climate, and behavior

“…However, in the following 13 years (2003-2016), a total of 26 infectious disease outbreaks/events, which was more than doubled, was reported. These 26 events involved humans with the following viral or bacterial infections: severe SARS [28], avian influenza virus H5N1 (2005)(2006), Neisseria mengititds serotype C sequence type complex T4821 (2003)(2004)(2005) [29], S. suis ST7 (2005) [30], avian influenza H5N1 [31], HGA (2006) [32], influenza H1N1 (2009) [33], New Bunyavirus (2009) [34][35][36], avian influenza H7N9 (2013) [37], dengue fever (2013) [38], West Nile virus (2014) [39], Zika virus (2015) [40], yellow fever (2016) [41], Rift Valley fever (2016) [42], Middle East respiratory syndrome (MERS) (2015) [43], poliomyelitis (Xinjiang) (2011) [6], Anaplasma capra (2014) [44], Shigella flexneri Xv (2003) [45], Tahyna virus (2006) [46], Babesia venatorum (2014) [47], Rickettsia sibirica BJ-90 (2012) [48], R. tarasevichiae (2012) [49], R. raoultii (2012) [50], Borrelia valaisiana (2010) [51], Anaplasma ovis-like (2014) [44], Wolbachia (2012) [52], adenovirus serotype 50 (2010) [53], and Creutzfeldt-Jakob disease [54].…”

Genetic variability of Rickettsia spp. in Ixodes persulcatus/Ixodes trianguliceps sympatric areas from Western Siberia, Russia: Identification of a new Candidatus Rickettsia species

“…ticks (Shpynov et al, 2006b). Widely distributed in Siberia Ixodes persulcatus ticks are commonly infected by Candidatus R. tarasevichiae, more rarely, by R. helvetica and, in solitary cases, by R. raoultii and R. sibirica (Rudakov et al, 2006;Shpynov et al, 2003Shpynov et al, , 2006a probably caused by these species have been described in Europe and China (Fournier et al, 2000;Mediannikov et al, 2008;Nilsson et al, 2010;Oteo and Portillo, 2012;Foldvari et al, 2013;Jia et al, 2013Jia et al, , 2014.…”

Molecular screening of ticks for the presence of Rickettsia species: A public health concern

“…Human infections with R. slovaca have been reported in some European countries such as France, Slovakia, Italy, Germany, Hungary, Spain, and Poland and recently in China [42][43][44][45]. While in northern Africa, R. slovaca and R. raoultii have only been detected in Morocco and in Algeria in Dermacentor marginatus ticks [46,47] though, no cases of human infection has been detected in northern Algeria.…”
