Assessment of the Geographic Distribution of Ornithodoros turicata (Argasidae): Climate Variation and Host Diversity
BACKGROUND Ornithodoros turicata is a veterinary and medically important argasid tick that is recognized as a vector of the relapsing fever spirochete Borrelia turicatae and African swine fever virus. Historic collections of O. turicata have been recorded from Latin America to the southern United States. However, the geographic distribution of this vector is poorly understood in relation to env...
متن کاملDifferential expression of tick Ixodes ricinus genes induced by blood feeding or infection: genetic analysis of ML domain containing proteins
Blood intake causes significant changes in ticks, triggering vital physiological processes including differential gene expression. A gene encoding Ixodes ricinus ML-domain containing protein (IrML) is one of the set of the genes that are strongly induced by blood meals. IrML belongs to the ML protein family that commonly occurs in diverse organisms and is involved in lipid binding and transport...
متن کاملAcquisition and subsequent transmission of Borrelia hermsii by the soft tick Ornithodoros hermsi.
Tick-borne relapsing fever is caused by spirochetes within the genus Borrelia. The hallmark of this disease is recurrent febrile episodes and high spirochete densities in mammalian blood resulting from immune evasion. Between episodes of spirochetemia when bacterial densities are low, it is unknown whether ticks can acquire the spirochetes, become colonized by the bacteria, and subsequently tra...
متن کاملDifferential expression of putative transbilayer amphipath transporters.
The aminophospholipid translocase transports phosphatidylserine and phosphatidylethanolamine from one side of a bilayer to another. Cloning of the gene encoding the enzyme identified a new subfamily of P-type ATPases, proposed to be amphipath transporters. As reported here, mammals express as many as 17 different genes from this subfamily. Phylogenetic analysis reveals the genes to be grouped i...
متن کاملThe major tick salivary gland proteins and toxins from the soft tick, Ornithodoros savignyi, are part of the tick Lipocalin family: implications for the origins of tick toxicoses.
The origins of tick toxicoses remain a subject of controversy because no molecular data are yet available to study the evolution of tick-derived toxins. In this study we describe the molecular structure of toxins from the soft tick, Ornithodoros savignyi. The tick salivary gland proteins (TSGPs) are four highly abundant proteins proposed to play a role in salivary gland granule biogenesis of th...
