Novel Ehrlichia Strain Infecting Cattle Tick Amblyomma neumanni, Argentina, 2018

Abstract

In 2018, we detected a novel Ehrlichia strain infecting Amblyomma neumanni ticks in Argentina. The novel strain is phylogenetically related to the ruminant pathogen E. ruminantium and represents a potential risk for veterinary and public health because A. neumanni ticks parasitize domestic and wild ruminants and bite humans.

Molecular characterization of novel Ehrlichia genotypes in Ixodes auritulus from Uruguay

“…strain Delta, and Ehrlichia sp. strain La Dormida) were identified ( Cicuttin et al., 2020 ; Eberhardt et al., 2020 ; Fargnoli et al., 2020 ).…”

Molecular Detection of Candidatus Rickettsia andeanae and Ehrlichia sp. in Amblyomma pseudoconcolor Aragão, 1908 (Acari: Ixodidae) from the Argentinian Patagonia

“…so far. : Amblyomma neumanni Ribaga, 1902 [ 31 ]; Amblyomma ovale Koch, 1844 [ 32 ]; A. parvum [ 33 , 34 ]; A. tigrinum [ 33 , 34 , 35 , 36 ]; and Amblyomma triste Koch, 1844 [ 37 ]. The Ehrlichia strain detected in A. pseudoconcolor in this work is not related to the remaining Ehrlichia strains previously detected in Argentina, at least considering those from which 16S rRNA gene sequences are available.…”

Characterization of “Candidatus Ehrlichia Pampeana” in Haemaphysalis juxtakochi Ticks and Gray Brocket Deer (Mazama gouazoubira) from Uruguay

“…strain La Dormida, and a Ehrlichia sp.) were detected in ticks of the genus Amblyomma [13,[33][34][35][36][37][38][39]. Recently, new Ehrlichia genotypes were described in Ixodes uriae from Chile and Ixodes auritulus from Uruguay [2,14].…”
