“…The absence of any typhus group rickettsiae in ixodid ticks in this study is consistent with previous studies that did not detect this bacterium in hard ticks in Ethiopia (Mediannikov et al, 2012a;Mura et al, 2008;Pader et al, 2012), suggesting that other hematophagous arthropods might play a role in the transmission of TG rickettsiae.…”

“…R. aeschlimannii, the agent of SFG rickettsiosis, had been detected in Hyalomma marginatum rufipes and R. africae, the agent of African tick bite fever (ATBF), has been detected in Amblyomma lepidum and Am. variegatum ticks from eastern Ethiopia (Mura et al, 2008), and also R. africae had been detected in pools of Amblyomma and Rhipicephalus ticks (Pader et al, 2012) (summarized in Fig. 1).…”

“…of the Spotted Fever and Transitional groups have been reported in A. (P.) persicus from Europe (Rehácek et al, 1977) and Africa (Pader et al, 2012), respectively. However, the vector competence of this tick in relation with these microorganisms must still be assessed.…”

High similarity of morphological traits has historically overshadowed the identities and distributions of poultry-associated soft ticks Argas (Persicargas) miniatus and Argas (Persicargas) persicus in America. In order to model the occurrence of both parasites in the continent, in the current study we performed morphological and molecular analyses to identify ticks collected in hen houses from Brazil and northern Chile. Combining these results with literature data, and the examination of Argas allotments deposited in the tick collections "Coleção Nacional de Carrapatos Danilo Gonçalves Saraiva" (Brazil), the "Coleção Acarológica do Instituto Butantan São Paulo" (Brazil), and the "Colección Zoológica de la Academia de Ciencia de Cuba" (Cuba), we present a critical list with the localities where A. (P.) miniatus and A. (P.) persicus have been reported in the American continent. Our results confirmed the presence of A. (P.) miniatus in Brazil and Cuba, and A. (P.) persicus in Chile, which in particular, constitutes the first molecularly confirmed report of the later species for South America. Although A. (P.) miniatus and A. (P.) persicus have been documented in 21 American countries, the identity of some reports must still be considered as uncertain until detailed morphological and/or molecular studies are performed. When contrasted to a Köppen-Geiger climate classification, A. (P.) miniatus predominantly occurs in equatorial and A. (P.) persicus in arid climates. However, until undetermined reports of both species are correctly identified, any conclusion on their geo-climatological occurrence throughout the American continent would be rather speculative.

“…ticks: H. punctata and H. sulcata in Spain [29,39], H. punctata in Cyprus [3] and H. parva in Turkey [20,36]. In other continents, R. hoogstraalii was associated to soft ticks [8,19,33,37]. Our finding of this organism not only in H. sulcata but also in I. ricinus could suggest a spillover of the rickettsia into I. ricinus, determined either by the intake of rickettsemic bloodmeals from lizards or by the cofeeding of the two tick species [59].…”

Importance of Common Wall Lizards in the Transmission Dynamics of Tick-Borne Pathogens in the Northern Apennine Mountains, Italy

During the investigations on ticks and tick-borne pathogens (TBP) range expansion in the Northern Apennines, we captured 107 Podarcis muralis lizards. Sixtyeight animals were infested by immature Ixodes ricinus, Haemaphysalis sulcata and H. punctata. Borrelia burgdorferi s.l. was detected in 3.7% of I. ricinus larvae and 8.0% of nymphs. Together with the species-specific B. lusitaniae, we identified B. garinii, B. afzelii and B. valaisiana. Rickettsia spp. (18.1% larvae, 12.0% nymphs), namely R. monacensis, R. helvetica and R. hoogstraalii, were also found in I. ricinus. R. hoogstraalii was detected in H. sulcata nymphs as well, while the two H. punctata did not harbour any bacteria. One out of 16 lizard tail tissues was positive to R. helvetica. Our results support the hypothesis that lizards are involved in the epidemiological cycles of TBP. The heterogeneity of B. burgdorferi genospecies mirrors previous findings in questing ticks in the area, and their finding in attached I. ricinus larvae suggests that lizards may contribute to the maintenance of different genospecies. The rickettsiae are new findings in the study area, and R. helvetica infection in a tail tissue indicates a systemic infection. R. hoogstraalii is reported for the first time in I. ricinus ticks. Lizards seem to favour the bacterial exchange among different tick species, with possible public health consequences.
