“…The bites showed the characteristic formation of blisters keeps the blood of the hosts flowing. Although these lesions can be considered "benign", some cases associated with certain species of Ornithodoros can be extremely painful and produce severe effects, causing strong allergic reactions, and even anaphylactic shocks (24,43,46,(50)(51)(52). Moreover, some Ornithodoros species (e.g.…”

Tick bites in humans are associated with the transmission of pathogens, anaphylactic shock, paralysis, and secondary infections. In this work we described six cases of tick bites in patients from Panama and Costa Rica. These bites were provoked for adults of Ornithodoros puertoricensis, Amblyomma cf. oblongoguttatum, Amblyomma ovale, and Ixodes cf. boliviensis, and a nymph of Amblyomma mixtum. The relationships of these species of ticks with the environment are explained. Among the reactions observed in the patients there are blisters, maculo-papular rash, granuloma, lymphadenopathy, and erythema migrans-like rash, but none referred symptoms compatible with an infectious disease. In the collected ticks a PCR battery was developed to rule out Borrelia, Rickettsia, Anaplasmataceae, and Coxiella diseases to the ticks from the cases 1, 2, 3 and 4, with negative results. Although no pathogen infections were evidenced, these finding indicate that the tick bites constitute a public health problem what goes unnoticed in many countries.

“…Considering previous published papers, the presumed geographical distribution of Ornithodoros species that are probable vectors of RFGB in Brazil is as follows (Fig. 1 ; Additional file 1 : Table S1): Ornithodoros brasiliensis in Rio Grande do Sul State [ 99 – 103 , 110 ]; O. rudis in the states of Maranhão and Goiás [ 104 , 105 , 111 ]; O. mimon in the states of Minas Gerais, Maranhão, Mato Grosso, Rio Grande do Norte, Pernambuco, Goiás, Ceará and São Paulo [ 105 , 106 , 111 – 113 ]; O. hasei in the states of Ceará, Maranhão, Espírito Santo, Mato Grosso, Mato Grosso do Sul and Amapá [ 105 , 114 – 116 ]; O. rietcorreai in the states of Ceará, Maranhão, Piauí, Tocantins, Bahia and Paraíba [ 105 , 107 , 108 , 111 , 113 , 117 – 119 ]; and O. tabajara in Ceará State [ 105 , 120 ].…”

Historical overview and update on relapsing fever group Borrelia in Latin America

Relapsing fever group Borrelia (RFGB) are motile spirochetes transmitted to mammalian or avian hosts through the bite of hematophagous arthropods, such as soft ticks (Argasidae), hard ticks (Ixodidae) and the human clothing lice. RFGB can infect pets such as dogs and cats, as well as birds, cattle and humans. Borrelia recurrentis, B. anserina and B. theileri are considered to have worldwide distribution, affecting humans, domestic birds and ruminants, respectively. Borrelia spp. associated with soft ticks are transmitted mainly by Ornithodoros ticks and thrive in endemic foci in tropical and subtropical latitudes. Nowadays, human cases of soft tick-borne relapsing fever remain neglected diseases in several countries, and the impact these spirochetes have on the health of wild and domestic animals is largely understudied. Human infection with RFGB is difficult to diagnose, given the lack of distinguishing clinical features (undifferentiated febrile illness). Clinically, soft tick or louse-borne relapsing fever is often confused with other etiologies, such as malaria, typhoid or dengue. In Latin America, during the first half of the twentieth century historical documents elaborated by enlightened physicians were seminal, and resulted in the identification of RFGB and their associated vectors in countries such as Mexico, Panama, Colombia, Venezuela, Peru and Argentina. Almost 80 years later, research on relapsing fever spirochetes is emerging once again in Latin America, with molecular characterizations and isolations of novel RFGB members in Panama, Bolivia, Brazil and Chile. In this review we summarize historical aspects of RFGB in Latin America and provide an update on the current scenario regarding these pathogens in the region. To accomplish this, we conducted an exhaustive search of all the published literature for the region, including old medical theses deposited in libraries of medical academies. RFGB were once common pathogens in Latin America, and although unnoticed for many years, they are currently the focus of interest among the scientific community. A One Health perspective should be adopted to tackle the diseases caused by RFGB, since these spirochetes have never disappeared and the maladies they cause may be confused with etiologies with similar symptoms that prevail in the region.

“…Indeed, lizards have been found infested by larvae and nymphs of Ixodes pacificus in the Nearctic region, and I. ricinus in the Palearctic region ( Mendoza-Roldan et al, 2019 ). Conversely, B. burgdorferi sensu lato in the Neotropical region probably is maintained by birds and small mammals, rather than lizards ( Barbieri et al, 2013 ; Ogrzewalska et al, 2016 ; De Oliveira et al, 2018 ). Furthermore, another paradigmatic example of the participation of ticks, associated to a certain level to reptiles, in the eco-epidemiology of zoonotic pathogens, is represented by Hyalomma aegyptium .…”

Reptile vector-borne diseases (RVBDs) of zoonotic concern are caused by bacteria, protozoa and viruses transmitted by arthropod vectors, which belong to the subclass Acarina (mites and ticks) and the order Diptera (mosquitoes, sand flies and tsetse flies). The phyletic age of reptiles since their origin in the late Carboniferous, has favored vectors and pathogens to co-evolve through millions of years, bridging to the present host-vector-pathogen interactions. The origin of vector-borne diseases is dated to the early cretaceous with Trypanosomatidae species in extinct sand flies, ancestral of modern protozoan hemoparasites of zoonotic concern (e.g., Leishmania and Trypanosoma ) associated to reptiles. Bacterial RVBDs are represented by microorganisms also affecting mammals of the genera Aeromonas, Anaplasma, Borrelia , Coxiella , Ehrlichia and Rickettsia , most of them having reptilian clades. Finally, reptiles may play an important role as reservoirs of arborivuses, given the low host specificity of anthropophilic mosquitoes and sand flies. In this review, vector-borne pathogens of zoonotic concern from reptiles are discussed, as well as the interactions between reptiles, arthropod vectors and the zoonotic pathogens they may transmit.
