Successful Feeding of Amblyomma coelebs (Acari: Ixodidae) Nymphs on Humans in Brazil: Skin Reactions to Parasitism
نویسندگان
چکیده
Identifying the tick species that successfully feed on humans would increase knowledge of the epidemiology of several tick-borne diseases. These species salivate into the host, increasing the risk of pathogen transmission. However, there is a lack of data in the literature regarding the ticks that prefer to feed on humans. Herein, we describe the successful feeding of Amblyomma coelebs Neumann nymphs on two of the authors after accidental tick bites occurred during field surveys in two preserved areas of Mato Grosso do Sul, Brazil. One of the host-parasite interactions was closely monitored, and the tick development, gross host skin alterations, and related sensations are presented.

The present study aimed to evaluate the occurrence of immune resistance in dogs successively infested with Amblyomma cajennense nymphs. Five animals were submitted to four consecutive infestations with A. cajennense nymphs, at fourteen-day intervals. For each infestation, 50 nymphs were used per animal and data on the parasitic and non-parasitic periods were recorded. The average recovering rat...

In Brazil, A. cajennense is the main vector of Rickettsia rickettsii, the etiological agent of «Rocky Mountain Spotted Fever». Besides the intense blood exploitation, the parasitism can affect the animal production capacity and usually determine leather depreciation, leading to secondary infections and myiasis. Although the adult stages have the equines as their preferable hosts, some authors [...

The immature stages of Neotropical ticks are poorly known and in many cases have not been described. This work presents a morphological description of Amblyomma brasiliense larvae (F1) and a redescription of nymphs (F1). A. brasiliense is reported as one of the most aggressive ticks to humans in Brazil. Immature ticks obtained from a laboratory colony initiated from adult specimens collected in...
متن کاملNotes on population dynamics of Amblyomma ticks (Acari: Ixodidae) in Brazil.
Previous population dynamics data, generated for Amblyomma parvum Aragão and Amblyomma cajennense (Fabricius) in Argentina and southeastern Brazil, have indicated that these ticks complete 1 generation per year, with larvae predominating in autumn, nymphs in winter, and mostly adults during spring and summer. The present study reports population dynamics data for free-living Amblyomma spp. tick...
