Elati, Khawla; Zweygarth, Erich; Mhadhbi, Moez; Darghouth, Mohamed Aziz; Nijhof, Ard M. (Frontiers Media, 2022-12-22)INTRODUCTION : Tropical theileriosis is a protozoan disease caused by Theileria annulata that affects cattle in Northern Africa, the Middle East and Asia where vector ticks of the genus Hyalomma occur. Various measures are ...

Dugat, Thibaud; Rossignol, Marie-Noelle; Rue, Olivier; Loux, Valentin; Marthey, Sylvain; Moroldo, Marco; Silaghi, Cornelia; Hoper, Dirk; Frohlich, Julia; Zweygarth, Erich; Lagree, Anne-Claire; Boulouis, Henri-Jean; Haddad, Nadia (American Society for Microbiology, 2016-11-01)Anaplasma phagocytophilum is a zoonotic tick-borne intracellular bacterium responsible for granulocytic anaplasmosis. As it is difficult to isolate and cultivate, only 20 A. phagocytophilum genomes have been sequenced to ...

Diaz-Sanchez, Sandra; Hernandez-Jarguin, Angelica; Fernandez de Mera, Isabel G.; Alberdi, Pilar; Zweygarth, Erich; Gortazar, Christian; De la Fuente, Jose (American Society for Microbiology, 2018-02-01)Here, we report the draft genome sequences of isolates of Anaplasma phagocytophilum, Anaplasma marginale, and Anaplasma ovis. The genomes of A. phagocytophilum (human), A. marginale (cattle), and A. ovis (goat) isolates ...

Elati, Khawla; Tajeri, Shahin; Isaiah, Obara; Mhadhbi, Moez; Zweygarth, Erich; Darghouth, Mohamed Aziz; Nijhof, Ard Menzo (Nature Research, 2023-10-24)The apicomplexan parasite Theileria annulata is transmitted by Hyalomma ticks and causes an acute lymphoproliferative disease that is invariably lethal in exotic cattle breeds. The unique ability of the schizont stage ...

Cabezas-Cruz, Alejandro; Zweygarth, Erich; Vancova, Marie; Broniszewska, Marzena; Grubhoffer, Libor; Passos, Lygia Maria Friche; Ribeiro, Mucio Flavio Barbosa; Alberdi, Pilar; De la Fuente, Jose (Society for General Microbiology, 2016-03)Recently, we obtained a rickettsial isolate (Ehrlichia sp. UFMG-EVT) from the haemolymph of engorged Rhipicephalus microplus tick females. On the basis of maximum-likelihood phylogenetic analysis using 16S rRNA gene, groEL, ...

Ferrolho, Joana; Simpson, Jennifer; Hawes, Philippa; Zweygarth, Erich; Bell-Sakyi, Lesley (Elsevier, 2016-06)Canine monocytic ehrlichiosis is caused by Ehrlichia canis, a small gram-negative coccoid bacterium that infects circulating monocytes. The disease is transmitted by the brown dog tick Rhipicephalus sanguineus s.l. and is ...

Salata, Cristiano; Moutailler, Sara; Attoui, Houssam; Zweygarth, Erich; Decker, Lygia; Bell-Sakyi, Lesley (Taylor and Francis, 2021)Although tick-borne infectious diseases threaten human and animal health worldwide, with constantly increasing incidence, little knowledge is available regarding vector–pathogen interactions and pathogen transmission. In ...

Oosthuizen, Marinda C.; Zweygarth, Erich; Collins, Nicola E.; Troskie, Milana; Penzhorn, Barend Louis (American Society for Microbiology, 2008-07)Babesiosis in a sable antelope (Hippotragus niger Harris, 1838) was first reported in 1930; the parasite was named Babesia irvinesmithi. Recently, specimens from an adult sable that presented with a sudden onset of disease ...

Alberdi, Pilar; Ayllón, Nieves; Cabezas-Cruz, Alejandro; Bell-Sakyi, Lesley; Zweygarth, Erich; Stuen, Snorre; De la Fuente, José (Elsevier, 2015-09)Anaplasma phagocytophilum is an intracellular rickettsial pathogen transmitted by Ixodes spp. ticks, which causes granulocytic anaplasmosis in humans, horses and dogs and tick-borne fever (TBF) in ruminants. In the United ...
