High prevalence of a host‐associated Anaplasma lineage in wild coatis (Nasua nasua) from the Brazilian Atlantic Forest

Medical and Veterinary Entomology, EarlyView.
Anaplasma sp. DNA was detected in 47.9% of free‐ranging coatis (Nasua nasua) sampled in Iguaçu National Park, southern Brazil. Molecular analyses revealed a genetically distinct Anaplasma lineage infecting coatis, differing from Anaplasma strains detected in associated tick populations.

Establishment and multiapproach characterization of Amblyomma sculptum (Acari: Ixodidae) cell line (ASE-14) from Brazil

Ticks and Tick-borne Diseases, 2022
The establishment and characterization of the ASE-14 cell line derived from embryos of Amblyomma sculptum is described here. Primary cultures were started, and after 60 days of culturing a confluent monolayer was formed and the first subculture was then carried out. After this, new subcultures were carried out every 4 weeks.

In Silico Characterization and Structural Modeling of Dermacentor andersoni p36 Immunosuppressive Protein

Advances in Bioinformatics, Volume 2018, Issue 1, 2018., 2018
Ticks cause approximately $17–19 billion economic losses to the livestock industry globally. Development of recombinant antitick vaccine is greatly hindered by insufficient knowledge and understanding of proteins expressed by ticks. Ticks secrete immunosuppressant proteins that modulate the host’s immune system during blood feeding; these molecules ...
