First evidence of Candidatus Neoehrlichia mikurensis in Hungary [PDF]

, 2013
Altogether 2004 Ixodes ricinus ticks, from 37 places in Hungary, were analysed in pools with a recently developed multiplex real-time PCR for the presence of Candidatus Neoehrlichia mikurensis and for other representatives of the genus. Ca.

Novel Anaplasmataceae agents Candidatus Ehrlichia hydrochoerus and Anaplasma spp. Infecting Capybaras, Brazil [PDF]

Emerging Infectious Diseases, 2022
We amplified Ehrlichia and Anaplasma DNA from Amblyomma dubitatum tick-infested capybaras (Hydrochoerus hydrochaeris) in southern Brazil. Sequencing of 16S rRNA, sodB, and groEL indicated a novel Ehrlichia species, and sequencing of 16S rRNA from 2 capybaras indicated a novel Anaplasma species. The tick vectors remain unknown.

Comparative Analysis of Wolbachia Genomes Reveals Streamlining and Divergence of Minimalist Two-Component Systems [PDF]

, 2015
Two-component regulatory systems are commonly used by bacteria to coordinate intracellular responses with environmental cues. These systems are composed of functional protein pairs consisting of a sensor histidine kinase and cognate response regulator ...

Anaplasmataceae Subversion of the Lysosomal Activity [PDF]

Journal of Bacteriology & Mycology: Open Access, 2018
Pathogenic bacteria belonging to the family Anaplasmataceae include species of the genera Ehrlichia Anaplasma and Neorickettsia These bacterial obligate intracellular parasites have evolved diverse mechanisms for evasion of host cellular defenses One of these mechanisms involves adaptations for survival in distinct intracellular compartments that ...

Ticks and Associated Pathogens From Rescued Wild Animals in Rainforest Fragments of Northeastern Brazil

Frontiers in Veterinary Science, 2020
The Ixodidae family comprises ticks that are hematophagous ectoparasites and are considered vectors of several hemoparasites from the Anaplasmataceae family and the genus Hepatozoon, Babesia, and Rickettsia.

Wild Rodents and Novel Human Pathogen Candidatus Neoehrlichia mikurensis, Southern Sweden

Emerging Infectious Diseases, 2011
We examined small mammals as hosts for Anaplasmataceae in southern Sweden. Of 771 rodents, 68 (8.8%) were infected by Candidatus Neoehrlichia mikurensis, but no other Anaplasmataceae were found. Candidatus N.

Survey of Anaplasmataceae bacteria in sheep from Senegal

Tropical Animal Health and Production, 2013
The authors studied the role of bacteria belonging to Anaplasmataceae family as the causes of acute illnesses of sheep in West Africa.We examined and sampled 120 febrile sheep in two regions of Senegal for this study. The DNA extracted from these blood samples was tested by PCR using two pairs of primers (groEL-based and 16S rRNA gene-based).In 52/120 ...

Novel genotypes of Hepatozoon spp. in small mammals, Brazil

Parasites & Vectors, 2022
Background Small mammals (rodents and marsupials) have been poorly explored for the occurrence of apicomplexan (genus Hepatozoon and genera of the order Piroplasmorida) and Anaplasmataceae agents in Brazil. Thus, this study investigated the occurrence of
