Effect of ionizing radiation exposure on Trypanosoma cruzi ubiquitin-proteasome...
Cerqueira, Paula Gonçalves; Silva, Danielle Gomes Passos; Rocha, João Pedro Vieira da; Mendes, Isabela Cecilia; Oliveira, Karla Andrade detIn recent years, proteasome involvement in the damage response induced by ionizing radiation (IR)became evident. However, whether proteasome plays a direct or indirect role in IR-induced damageresponse still unclear. Trypanosoma cruzi is a human parasite capable of remarkable high tolerance toIR, suggesting a highly efficient damage response system. Here, we investigate the role of T. cruzi pro-teasome in the ...
Amblyomma imitator: a novel vector for Rickettsia rickettsii in Mexico and Sout...
Oliveira, Karla Andrade deCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Rickettsioses, doenças de importância mundial, são causadas por bactérias pequenas, gram-negativas e intracelulares obrigatórias, que são transmitidas ao homem através de carrapatos, pulgas, ácaros e piolhos. O gênero Rickettsia tem sido classicamente dividido em dois grupos, o grupo tifo (TG) e o grupo de febre maculosa (SFG). Nos Estados Unidos e Mé...
Molecular identification of Rickettsia felis in ticks and fleas from an endemic...
Oliveira, Karla Andrade de; Oliveira, Luciana Souza de; Dias, C. C. A.; Silva Júnior, Abelardo; Lamëgo, Márcia Rogéria de Almeida; Amalda, G.Rickettsioses are arthropod-borne diseases caused by parasites from the Order Rickettsiales. The most prevalent rickettsial disease in Brazil is Brazilian Spotted Fever (BSF). This work intends the molecular detection of those agents in ectoparasites from an endemic area of BSF in the state of Espírito Santo. A total of 502 ectoparasites, among them Amblyomma cajennense, Amblyomma dubitatum (A. cooperi), Riphic...
Amblyomma imitator ticks as vectors of Rickettsia rickettsii, Mexico.
Oliveira, Karla Andrade de; Pinter, Adriano; Medina Sanchez, Aaron; Boppana, Venkata D.; Wikel, Stephen Kenneth; Saito, Tais B.; Shelite, ThomasRickettsia rickettsii is a gram-negative, obligate, intracellular bacterium and the cause of Rocky Mountain spotted fever (RMSF). In Mexico, its transmission has been attributed to Rhipicephalus sanguineus and Amblyomma cajennense ticks. Amblyomma imitator has close affi nity with A. cajennense and was formerly confused with this species. These ticks’ distributional range extends from southern Texas, southward ...
