| O presente trabalho teve como objetivo verificar a forma de penetração do fungo Metarhizium anisopliae [METSCH. (SOROKIN, 1883)] em carrapatos da espécie Rhipicephalus sanguineus (LATREILLE, 1806), assim como as lesões infringidas nos tecidos internos do ácaro. A forma de aderência e penetração do fungo foi estudada através da microscopia eletrônica de varredura e a ação do fungo nos tecidos internos avaliada em secções histológicas convencionais. Para observação destes eventos, realizaram-se infecções experimentais em 11 grupos de fêmeas ingurgitadas do carrapato R. sanguineus contendo 12 fêmeas ingurgitadas cada. Para tal, as fêmeas ingurgitadas foram banhadas durante 3 minutos, sob agitação manual, em suspensão com concentração 108 conídios/mL. No caso... |

| We herein report tick (Acari: Ixodidae) infestation of four domestic dogs wandering inside Serra de Caldas Novas State Park, Goiás. Twenty seven ticks were collected from these hosts along nine days in November 2008. Ticks were identified as adults of Amblyomma cajennense, Amblyomma ovale, Amblyomma tigrinum and Rhipicephalus sanguineus as well as Amblyomma spp. nymphs. One of the dogs displayed facial myoclonus, a symptom of canine distemper. Such disease is a serious viral and contagious disease of dogs and also of several wild animals. Overall tick species found on dogs clearly showed the transit of these hosts between the natural areas of the park and anthropic areas, urban or rural. Such situation illustrates the potential of dogs to transmit... |

| We herein describe ticks parasitizing birds in forest fragments along the Uberabinha River, a major watercourse that cuts through patches of remnants of Brazilian savannah in Uberlândia, Minas Gerais, Brazil. Overall 352 birds from 62 species, overwhelmingly, Passeriformes, were captured with mist-nets. The most abundant bird species was Basileuterus hypoleucus (n=36), followed by Lanio penicillata (n=24) and Thalurania furcata (n=23). Thirty one birds, all Passeriformes, were found infested with 56 ticks from which 12 were larvae and 44 nymphs, all from the Amblyomma genus. Highest infestation prevalence was found on Taraba major (66.6%), Thamnophilus pelzeni (60%) and Saltator maximus (50%). The mean intensity of tick infestation was low (1.8 tick per... |
