“…1 Related to the bacterial diseases transmitted by ticks are Lyme disease, rickettsioses, and tularemia. [2][3][4][5][6][7] Tiboviruses (tick-borne viruses) cause many symptoms with severe effects that affect the central nervous system, such as meningitis, meningoencephalitis with high sequelae, and hemorrhagic diseases. [8][9][10] Protozoan infections, for example, the babesiosis (Babesia bigemina), may also be transmitted by ticks.…”

This overview highlights the importance of characterization of biogenic nanoparticles of silver and silver chloride in order to understand the action on ticks or pathogens transmitted by them. These nanoparticles appear as important active principles in this area. They can act against ticks or against major pathogens transmitted by the bite of ticks such as bacteria, viruses or protozoa with equal or better efficacy of antibiotics, antiviral or antiparasitic agents. Anti-tick activities on Rhipicephalus (Boophilus) microplus, Hyalomma anatolicum, Hyalomma isaaci and Haemaphysalis bispinosa are discussed. Perspectives of these nanoparticles acting on bacteria, viruses and protozoa infections are also discussed.

“…Additional Rickettsia species, like R. massiliae, R. monacensis, R. aeschlimannii and R. helvetica, are considered as etiological agents of Mediterranean spotted fever-like illness in the Mediterranean basin. 2 Four tick-borne Rickettsiae have been currently identified in humans in Greece: R. conorii, R. aeschlimannii, R. sibirica mongolotimonae and R. slovaca, while R. massiliae and R. rhipicephali were identified only in ticks. [3][4][5][6][7][8][9] Unusual increased tick aggressiveness was observed in summer 2008 in northeastern Greece resulting in increased number of persons bitten by ticks, and two fatal cases, one caused by R. conorii and one by Crimean-Congo hemorrhagic fever virus (the first and only report in Greece).…”

Background: Ticks serve as vectors and reservoirs for a variety of bacterial, viral and protozoan pathogens affecting humans and animals. Unusual increased tick aggressiveness was observed in 2008-2009 in northeastern Greece. The aim of the study was to check ticks removed from persons during 2009 for infection with Rickettsia species.Methods: A total of 159 ticks were removed from 147 persons who sought medical advice in a hospital. Tick identification was performed morphologically using taxonomic keys. DNA was extracted from each individual tick and a PCR assay targeting the rickettsial outer membrane protein A gene of Rickettsia spp. was applied.Results: Most of the adult ticks (132/153, 86.3%) were Rhipicephalus sanguineus. Rickettsiae were detected in 23 of the 153 (15.0%) adult ticks. Five Rickettsiae species were identified: R. aeschlimannii, R. africae (n=6), R. massilae (4), R. monacensis (1), and Candidatus R. barbariae (1). To our knowledge, this is the first report of R. africae, R. monacensis, and Candidatus R. barbariae in Greece.Conclusions: Several Rickettsia species were identified in ticks removed from humans in Greece, including those that are prevalent in northern and southern latitudes.

“…The rickettsiae are a group of obligate intracellular gram-negative bacteria responsible for serious human diseases, such as Lymphangitis-associated rickettsioses (LAR), and Mediterranean spotted fever (Parola et al 2013;Portillo et al 2015). Rickettsial infections are one of the oldest known vector borne diseases, and infections are mainly spread through fleas, mites (chiggers), lice, or ticks (Portillo et al 2015).…”

“…Rickettsial infections are one of the oldest known vector borne diseases, and infections are mainly spread through fleas, mites (chiggers), lice, or ticks (Portillo et al 2015). To date, 10 spotted fever group (SFG) rickettsiae, namely Candidatus Rickettsia vini, R. aeschlimannii, R. africae, R. conorii, R. felis, R. helvetica, R. hoogstraalii, R. monacensis, R. raoultii and R. slovaca, have been molecularly detected in ticks mainly collected from humans in Turkey (Gargili et al 2012;Orkun et al 2014;Keskin et al 2014Keskin et al , 2016.…”

“…sibirica mongolitimonae, etiological agent of Lymphangitis-associated rickettsioses (LAR), is a member of Rickettsia sibirica species complex within the spotted fever group (SFG) of rickettsiae (Edouard et al 2013;Parola et al 2013). Maculopapular rash, fever, and multiple eschars are basic clinical signs and symptoms of R. sibirica mongolitimonae infection (Ramos et al 2013;Portillo et al 2015). The first human infection caused by R. sibirica mongolitimonae was reported in France in 1996 (Raoult et al 1996).…”
