Identification and characterization of antimicrobial peptide, defensin, in the taiga tick, Ixodes persulcatus.
Y. Saito,Satoru Konnai,Shinji Yamada,Saiki Imamura,Hideto Nishikado,T. Ito,Misao Onuma,Kazuhiko Ohashi +7 more
TL;DR: Results suggest that I. persulcatus defensin may be playing a significant role in the defence against microbes from bloodmeals.

Acquisition and transmission of Theileria parva by vector tick, Rhipicephalus appendiculatus.
Satoru Konnai,Saiki Imamura,Chie Nakajima,William H. Witola,Shinji Yamada,Martin Simuunza,Andrew Nambota,Jun Yasuda,Kazuhiko Ohashi,Misao Onuma +9 more
TL;DR: Since the rate of transmission of T. parva from infected cattle to ticks and vice versa and the serological evidence of exposure to R. appendiculatus ticks in naturally exposed cattle were relatively high, it would be wise in such a case to consider vector control as well as vaccination against ECF as control measures.

Effect of vaccination with a recombinant metalloprotease from Haemaphysalis longicornis
Saiki Imamura,Itabajara da Silva Vaz,Satoru Konnai,Shinji Yamada,Chie Nakajima,Misao Onuma,Kazuhiko Ohashi +6 more
TL;DR: Rabbit repeatedly infested with H. longicornis recognized rHLMP1, suggesting that the immune-response against HLMP1 is naturally induced through the feeding of ticks, and strategies to block this defense system with an anti-tick vaccine based on a metalloprotease are developed.

Molecular identification and expression analysis of lipocalins from blood feeding taiga tick, Ixodes persulcatus Schulze.
Satoru Konnai,Hideto Nishikado,Shinji Yamada,Saiki Imamura,Takuya Ito,Misao Onuma,Shiro Murata,Kazuhiko Ohashi +7 more
TL;DR: R reverse transcriptase-PCR analysis revealed that lipocalin genes were expressed specifically in the salivary glands throughout life cycle stages of the ticks and were up-regulated by blood feeding, which indicates that native lipocalins are potentially secreted into the host during tick feeding.

Quantitative analysis of cytokine mRNA expression and protozoan DNA load in Theileria parva-infected cattle.
Shinji Yamada,Satoru Konnai,Saiki Imamura,Martin Simuunza,Mwelwa Chembensofu,Amos Chota,Andrew Nambota,Misao Onuma,Kazuhiko Ohashi +8 more
TL;DR: Observations indicated that high protozoan load and resulting intense inflammatory responses might be involved in the severity of clinical signs observed in T. parva-infected animals.
