Genome of the longhorned tick Haemaphysalis longicornis
2023We re-assembled the genome of the longhorned tick, Haemaphysalis longicornis based on the published but highly redundant version. It is a livestock pest widespread in East and Central Asia, Oceania and North America. It parasitizes mammals and birds, transmits pathogens associated with several tickborne diseases, and is also the vector of oriental ...

The development of oocytes in the ovary of a parthenogenetic tick, Haemaphysalis longicornis
Parasitology International, 2018Haemaphysalis longicornis is an important vector of various pathogens in domestic animals and humans. The tick is a unique species with bisexual and parthenogenetic races. Although mating induces oocyte development, it is possible in the parthenogenetic race to complete oogenesis without copulation. Here we examined the developmental process of oocytes

Effect of vaccination with a recombinant metalloprotease from Haemaphysalis longicornis
Experimental and Applied Acarology, 2009We report the cloning, expression and characterization of an Haemaphysalis longicornis metalloprotease (named HLMP1). The gene encodes a predicted 550 aminoacid protein with similarity to metalloproteases of the reprolysin family. The protein sequence contains a signal sequence, the zinc-binding motif (HEXXHXXGXXH) common to metalloproteases and a ...

Development of Theileria sergenti in the haemolymph of the tick, Haemaphysalis longicornis
Zentralblatt für Bakteriologie, Mikrobiologie und Hygiene. Series A: Medical Microbiology, Infectious Diseases, Virology, Parasitology, 1987The haemolymph of adult tick Haemaphysalis longicornis infected with Theileria sergenti, was examined at regulat intervals of time. As a result, kinetics could be detected in the haemolymph for the first time 25 days after the engorgement. The kinetics detected could be classified into three types on the basis of their morphological characteristics ...

Effects of temperature on development and growth in the tick,Haemaphysalis longicornis
Experimental & Applied Acarology, 1987As a part of ecological studies on Haemaphysalis longicornis, the effects of controlled temperatures (12, 15, 20, 25 and 30 degrees C; approximately 100% RH) on development and growth of the tick were investigated and the critical low temperature for each stage in the life cycle was estimated.

MOLECULAR EVIDENCE OF BABESIA EQUI TRANSMISSION IN HAEMAPHYSALIS LONGICORNIS
The American Journal of Tropical Medicine and Hygiene, 2007We studied the tick, Haemaphysalis longicornis, to determine the possibility of both transovarial and transstadial transmission of Babesia equi. We also studied the usefulness of the needle injection method for pathogenic tick-transmitted organisms including Babesia parasites. Erythrocytes infected with B. equi were injected into the midgut of engorged

Characterization of proteolytic enzymes expressed in the midgut of Haemaphysalis longicornis.
The Japanese journal of veterinary research, 1999The proteolytic activities present in midguts of both fed and unfed Haemaphysalis longicornis were assessed by using the gelatin-substrate gel electrophoresis and inhibitor sensitivity analyses. Three predominant (116, 48 and 48 kDa) and two weak (55 and 60 kDa) proteinase bands were commonly expressed in both unfed and fed ticks, while a weak 80 kDa ...

The experimental transmission of a recently designated Theileria uilenbergi pathogenic for sheep and goats in Northern China is described. Haemaphysalis qinghaiensis nymphs and adults developed from larvae and nymphs engorged on sheep infected with T. uilenbergi were able to respectively transmit the latter to sheep. However, when H.
