Rocky Mountain spotted fever caused by Rickettsia rickettsii and Lyme borreliosis caused by Borrelia sp. spirochetes are the most serious tick-borne diseases in Brazil and the Czech Republic, respectively. The midgut is the primary interface between the ingested pathogen and the tick. Tick-borne pathogens have to withstand the robust midgut immune reactions that maintain the midgut micro…
Ticks are ectoparasitic arthropods that necessarily feed on the blood of vertebrates and versatile vectors of a wide variety of pathogens. Among the pathogens transmitted to humans by ticks, Rickettsia rickettsii, the etiological agent of Rocky Mountain spotted fever, is one of the most lethal. R. rickettsii presents transovarial and transstadial transmissions, so that ticks, in addition …
Mass Spectrometry (MS) is a potent tool which is broadly used in the analysis of different molecules. The development of softer ionization methods, such as matrix-assisted laser desorption/ionization ionization (MALDI) and eletrospray ionization (ESI) associated with less expensive and easier-to-operate analyzers, for instance quadrupole, time-of-flight (TOF), and ion trap made possible t…
Rock Mountain Spotted Fever, known in Brazil as Brazilian Spotted Fever (BSF), is the most severe rickettsiosis that affects humans. The etiologic agent of BSF, the obligate intracellular bacterium Rickettsia rickettsii, is transmitted by bite of different tick species. In Brazil, the ticks Amblyomma cajennense and A. aureolatum are the two major vectors. Besides the low prevalence of inf…
Ticks have parasitic habit of life, feeding obligatory on blood and/or lymph of vertebrates. As a result of hematophagy, these arthropods transmit a wide variety of pathogens. Among the tick-borne rickettsial diseases, we highlight Bovine Anaplasmosis (BA) and Brazilian Spotted Fever (BSF). BA is a severe disease that affects cattle, being caused by Anaplasma marginale and transmitted by …

Rickettsia rickettsii is the etiologic agent of Rocky Mountain spotted fever. After the transmission through the bite of an infected tick, the bacterium infects the endothelial cells of the vertebrate host, where it proliferates, causing vasculitis, with a potentially fatal evolution. In Brazil, the main vector of R. rickettsii is Amblyomma sculptum [a species of the Amblyomma cajennense …

Gram-negative bacteria use the Type 4 Secretion System (T4SS) to translocate effectors (DNA and proteins) to the host cell cytosol, where they play different roles, avoiding bacterial elimination and ensuring replication. The gene modulation of T4SS components has already been described in R. rickettsii infecting organs of its tick vector Amblyomma aureolatum exposed to different environm…
Although Amblyomma sculptum (previously named Amblyomma cajennense) and Amblyomma aureolatum belong to the same genus and are important vectors of Rickettsia rickettsii, these species are distinct in relation to susceptibility to infection. A. aureolatum is more susceptible to infection than A. sculptum, providing more specimens of experimentally infected ticks. On the other hand, A. aure…

Ticks are obligate blood-sucking arthropods and vectors of numerouspathogens that cause severe diseases to humans and other animals, being of interest from the 'One Health' point of view. Besides life-threatening animal life, ticks and tick-borne diseases (TBDs) also cause severe losses to the global economy, by decreasing animal productivity. Currently, tick control relies mainly on the …
