Epidemiology of toxoplasmosis: role of the tick Haemaphysalis longicornis
BACKGROUND Toxoplasma gondii infection is mainly caused by ingestion of water or food that is contaminated with oocysts excreted by cats, or by eating raw meat containing T. gondii tissue cysts. However, oral transmission does not explain the common occurrence of toxoplasmosis in a variety of hosts, such as herbivorous animals, birds, and wild rodents. Little information exists on the maintenan...
متن کاملVaccination effects of recombinant chitinase protein from the hard tick Haemaphysalis longicornis (Acari: Ixodidae).
The success of immunological method for the control of ticks depend on the use of potential key antigens as tick vaccine candidates. Chitinase is induced by ecdysteroids to degrade the older chitin at the time of molting. Previously, we cloned a gene encoding 113 kDa protein (CHT1) of Haemaphysalis longicornis, and identified the CHT1 as a protein of chitinase (You et al. 2003). In this study, ...
متن کاملRegulation of the vitellogenin receptor during Drosophila melanogaster oogenesis.
In many insects, development of the oocyte arrests temporarily just before vitellogenesis, the period when vitellogenins (yolk proteins) accumulate in the oocyte. Following hormonal and environmental cues, development of the oocyte resumes, and endocytosis of vitellogenins begins. An essential component of yolk uptake is the vitellogenin receptor. In this report, we describe the ovarian express...
متن کاملMultiple ferritins are vital to successful blood feeding and reproduction of the hard tick Haemaphysalis longicornis.
Ticks are obligate hematophagous parasites and important vectors of diseases. The large amount of blood they consume contains great quantities of iron, an essential but also toxic element. The function of ferritin, an iron storage protein, and iron metabolism in ticks need to be further elucidated. Here, we investigated the function a newly identified secreted ferritin from the hard tick Haemap...
متن کاملIdentification and characterization of the plasma kallikrein-kinin system inhibitor, haemaphysalin, from hard tick, Haemaphysalis longicornis.
The plasma kallikrein-kinin system inhibitor, haemaphysalin, from the hard tick, Haemaphysalis longicornis, was identified. It was found that haemaphysalin inhibited activation of the plasma kallikrein-kinin system by interfering with reciprocal activation between factor XII and prekallikrein. It did not, however, inhibit amidolytic activities of factor XIIa and kallikrein. Direct binding assay...
