There are several studies on the molecular detection of different pathogens in ticks, mainly within the Ixodidae family. However, the number of studies related to the molecular detection of pathogens in Argasids is considerably smaller, but no less important. Studies of molecular detection of pathogens in ticks are of fundamental importance because they give us information about which age…
The genus Bartonella (Rhizobiales; Bartonellaceae) encompasses facultative intracellular Gram-negative bacteria that mainly parasitize erythrocytes and endothelial cells of mammals, and can cause zoonoses with clinical manifestations ranging from moderate to severe, depending on the Bartonella species involved and the immune status of the mammalian host. Cats, rodents and bats act as rese…
Ticks are arthropods of great medical and veterinary importance, with many species responsible for transmitting viruses, bacteria and protozoa to their hosts. Some of the tick-borne pathogens are difficult to grow in vitro, and do not grow in artificial media. Tick cell culture has been an excellent tool to isolate and study pathogens, allowing the production of antigenic material for dia…
The first line of embryonic tick cells established in Brazil was to Amblyomma sculptum Berlese, whose cellular products were patented (see background). This species, until recently was synonym of Amblyomma cajennense (Fabricius). The species A. cajennense is restricted to the Amazon and part of the Midwest, while A. sculptum occurs in the rest of the country, and this is the main species …

Chigger mites (Thrombidiformes: Trombiculidae) are parasites of terrestrial vertebrates, and can even parasite human beings. During feeding, these animals inject digestive enzymes into the host skin, which can trigger inflammatory reactions, known usually as thrombiculiasis. There is also the possibility, if these mites are infected, from transmitting pathogens to the host. The present wo…
Among the mites of medical-veterinary importance, the families Trombiculidae and Macronyssidae, which parasitize bats, are poorly studied, especially their participation in the epidemiological chain of pathogens, some of which cause serious diseases. Chigger mites have about 70 species recorded for Brazil. Of these, only eight have already been found parasitizing bats, while of the 26 spe…
Brazil has 59 species of Trombiculidae parasitizing different animal groups. Of these, only 7 species were reported for birds, 1 of Apolonia, 1 of Blankaartia, 2 of Eutrombicula, 1 of Neoschoengastia and 2 of Parasecia. The larvae can cause deep and pruritic lesions at the site of the bite, in addition to intense skin reactions in the host, this dermatitis is popularly known as trombiculi…

The tick cell lines represent a useful tool when it comes to genetic manipulation of pathogens, as well as for gene expression studies. Through transcriptomic analysis, it is possible to identify expressed transcripts involved in the tick-pathogen interaction, and to obtain a better understanding of the molecular mechanisms associated with this interaction. However, little is known about …
There are about 3,300 species of chiggers, and most of these type species are deposited in the Systematic Entomology Laboratory (SEM), in the United States Department of Agriculture (USDA), Beltsville MD. Then, before the elaboration the redescriptions of several species, due to the poor original descriptions, a type catalogue is necessary to have the exact dimension of that collection. T…
