Evidence of the role of tick subolesin in gene expression
(BioMed Central, 2008-08-02)
Background: Subolesin is an evolutionary conserved protein that was discovered recently in Ixodes scapularis as a tick protective antigen and has a role in tick blood digestion, reproduction and development. In other ...
Allopatric speciation in ticks: Genetic and reproductive divergence between geographic strains of Rhipicephalus (Boophilus) microplus
(BioMed Central, 2009-02-25)
Background: The cattle tick, Rhipicephalus (Boophilus) microplus, economically impact cattle industry in tropical and subtropical regions of the world. The morphological and genetic differences among R. microplus strains ...
Expression of recombinant Rhipicephalus (Boophilus) microplus, R. annulatus and R. decoloratus Bm86 orthologs as secreted proteins in Pichia pastoris
(BioMed Central, 2008-02-14)
Background: Rhipicephalus (Boophilus) spp. ticks economically impact on cattle production in Africa and other tropical and subtropical regions of the world. Tick vaccines constitute a cost-effective and environmentally ...
Prevalence and genotypes of Anaplasma species and habitat suitability for ticks in a Mediterranean ecosystem
(American Society for Microbiology, 2008-12)
Anaplasma species are tick-transmitted pathogens that impact veterinary and human health. Sicily is one of the locations where these pathogens are endemic. Sicily represents a typical Mediterranean ecosystem to study ...
Anaplasma phagocytophilum and Anaplasma marginale elicit different gene expression responses in cultured tick cells
(Hindawi Publishing Corporation, 2009)
The genus Anaplasma (Rickettsiales: Anaplasmataceae) includes obligate tick-transmitted intracellular organisms, Anaplasma phagocytophilum and Anaplasma marginale that multiply in both vertebrate and tick host cells. ...
Sp110 transcription is induced and required by Anaplasma phagocytophilumfor infection of human promyelocytic cells
(BioMed Central, 2007-09-20)
Background: The tick-borne intracellular pathogen, Anaplasma phagocytophilum (Rickettsiales: Anaplasmataceae) causes human granulocytic anaplasmosis after infection of polymorphonuclear leucocytes. The human Sp110 gene is ...
Silencing of genes involved in Anaplasma marginale-tick interactions affects the pathogen developmental cycle in Dermacentor variabilis
(BioMed Central, 2009-07-16)
Background: The cattle pathogen, Anaplasma marginale, undergoes a developmental cycle in ticks that begins in gut cells. Transmission to cattle occurs from salivary glands during a second tick feeding. At each site of ...
Phylogeographic analysis reveals association of tick-borne pathogen, Anaplasma marginale, MSP1a sequences with ecological traits affecting tick vector performance
(BioMed Central, 2009-09-01)
Background: The tick-borne pathogen Anaplasma marginale, which is endemic worldwide, is the type species of the genus Anaplasma (Rickettsiales: Anaplasmataceae). Rhipicephalus (Boophilus) microplus is the most important ...
Vaccination with recombinant Boophilus annulatus Bm86 ortholog protein, Ba86, protects cattle against B. annulatus and B. microplus infestations
(BioMed Central, 2009-03-31)
Background: The cattle ticks, Boophilus spp., affect cattle production in tropical and subtropical regions of the world. Tick vaccines constitute a cost-effective and environmentally friendly alternative to tick control. ...
Sequence analysis of the msp4 gene of Anaplasma phagocytophilum strains
(American Society for Microbiology, 2005-03)
The causative agent of human granulocytic ehrlichiosis was recently reclassified as Anaplasma phagocytophilum, unifying previously described bacteria that cause disease in humans, horses, dogs, and ruminants. For the ...
