Journal ArticleDOI
In vitro assessment of Metarhizium anisopliae isolates to control the cattle tick Boophilus microplus
Ana Paula Guedes Frazzon,Itabajara da Silva Vaz Junior,Aoi Masuda,Augusto Schrank,Marilene Henning Vainstein +4 more
TL;DR: Isolates of M. anisopliae taken from experimentally infected ticks proved to be more pathogenic than fungus maintained on culture media and suggested that, in general, virus free isolates were more infective.
Journal ArticleDOI
Isolation of an aspartic proteinase precursor from the egg of a hard tick, Boophilus microplus
Carlos Logullo,I. Da Silva Vaz,Marcos Henrique Ferreira Sorgine,Gabriela O. Paiva-Silva,F.S. Faria,Russolina B. Zingali,M.F.R. de Lima,Leonardo Araujo de Abreu,E.F. Oliveira,Elias W. Alves,Hatisaburo Masuda,Joao Carlos Gonzales,Aoi Masuda,Pedro L. Oliveira +13 more
TL;DR: Western blot analysis using anti-BYC monoclonal antibodies showed proteolytic processing of BYC during embryogenesis and suggested activation of the enzyme during development, and a role of BYc in degradation of vitellin, the major yolk protein of tick eggs, is discussed.
Journal ArticleDOI
Cloning and functional expression of a Boophilus microplus cathepsin L-like enzyme.
Gaby Renard,José Fernando Garcia,Felipe C. Cardoso,Marc François Richter,Judy A. Sakanari,Luiz Shozo Ozaki,Carlos Termignoni,Aoi Masuda +7 more
TL;DR: A cysteine proteinase gene homologous to cathepsins L genes was isolated from a B. microplus cDNA library and its optimal enzymatic activity on both fluorogenic and protein substrates was found to occur at an acidic pH.
Journal ArticleDOI
ABC transporter efflux pumps: a defense mechanism against ivermectin in Rhipicephalus (Boophilus) microplus.
Paula Cristiane Pohl,Guilherme M. Klafke,Danielle D. Carvalho,João Ricardo Martins,Sirlei Daffre,Itabajara da Silva Vaz,Aoi Masuda +6 more
TL;DR: The ability of ABC transporter inhibitors to enhance ivermectin (IVM) sensitivity was tested in larvae and adult females of Rhipicephalus (Boophilus) microplus and reports the first known evidence for the participation of ABC transporters in IVM resistance in R. microplus.
Journal ArticleDOI
The quest for a universal vaccine against ticks: cross-immunity insights.
Luís Fernando Parizi,Naftaly Githaka,Carlos Logullo,Satoru Konnai,Aoi Masuda,Kazuhiko Ohashi,Itabajara da Silva Vaz +6 more
TL;DR: Progress towards effective anti-tick vaccines is reviewed in the light of emerging data from studies including heterologous tick challenge, indicating that the decades-long search for a universal tick vaccine is making progress, with such a vaccine likely to be based on multiple cross-reactive antigens.
