Molecular and serological detection of Ehrlichia spp. in cats on São Luís Island, Maranhão, Brazil Detecção molecular e sorológica de Ehrlichia spp. em gatos da ilha de São Luís, Maranhão, Brasil

Revista Brasileira de Parasitologia Veterinária, 2012
Ehrlichiosis is a tick-borne disease that affects both humans and animals. The few existing reports on ehrlichiosis in Brazilian cats have been based on observation of morulae in leukocytes and, more recently, on molecular detection of Ehrlichia sp.

The glycoprotein TRP36 of Ehrlichia sp. UFMG-EV and related cattle pathogen Ehrlichia sp. UFMT-BV evolved from a highly variable clade of E. canis under adaptive diversifying selection

Parasites & Vectors, 2014
Background A new species of Ehrlichia, phylogenetically distant from E. ruminantium, was found in 2010 infecting cattle in Canada. In 2012 and 2013, we reported the in vitro propagation, molecular and ultrastructural characterization of Ehrlichia sp ...

Sequential Evaluation of Dogs Naturally Infected withEhrlichia canis,Ehrlichia chaffeensis,Ehrlichia equi,Ehrlichia ewingii, orBartonella vinsonii [PDF]

Journal of Clinical Microbiology, 1998
ABSTRACTHistorically, disease manifestations in dogs seroreactive toEhrlichia canisantigens by indirect immunofluorescent antibody testing have been attributed to infection with eitherE. canisorEhrlichia ewingii. A 1996 study by Dawson and colleagues provided PCR evidence that healthy dogs from southeastern Virginia could be naturally infected ...

The super repertoire of type IV effectors in the pangenome of Ehrlichia spp. provides insights into host-specificity and pathogenesis.

PLoS Computational Biology, 2021
The identification of bacterial effectors is essential to understand how obligatory intracellular bacteria such as Ehrlichia spp. manipulate the host cell for survival and replication. Infection of mammals-including humans-by the intracellular pathogenic

Nanobodies as next‐generation targeting platforms: From discovery technologies to translational biomedicine

VIEW, EarlyView.
Nanobodies, derived from the variable domains of camelid heavy‐chain‐only antibodies, have emerged as transformative biomedical tools due to their nanoscale size, exceptional stability, and unique capacity to recognize cryptic epitopes. This review provides a comprehensive overview of the field, outlining the structural and biochemical features of ...
