Abstract
Although vaccines are one of the environmentally friendly means to prevent the spread of ticks, there is currently no commercial vaccine effective against Haemaphysalis longicornis ticks. In this study, we identified, characterized, localized, and evaluated the expression patterns, and tested the immunogenic potential of a homologue of Rhipicephalus microplus ATAQ in H. longicornis (HlATAQ). HlATAQ was identified as a 654 amino acid-long protein present throughout the midgut and in Malpighian tubule cells and containing six full and one partial EGF-like domains. HlATAQ was genetically distant (homology < 50%) from previously reported ATAQ proteins and was expressed throughout tick life stages. Its expression steadily increased (p < 0.001) during feeding, reached a peak, and then decreased slightly with engorgement. Silencing of HlATAQ did not result in a phenotype that was significantly different from the control ticks. However, H. longicornis female ticks fed on a rabbit immunized with recombinant HlATAQ showed significantly longer blood-feeding periods, higher body weight at engorgement, higher egg mass, and longer pre-oviposition and egg hatching periods than control ticks. These findings indicate that the ATAQ protein plays a role in the blood-feeding-related physiological processes in the midgut and Malpighian tubules and antibodies directed against it may affect these tissues and disrupt tick engorgement and oviposition.

Abstract
Background Ticks can transmit numerous tick-borne pathogens and cause a huge economic loss to the livestock industry. Tick vaccines can contribute to the prevention of tick-borne diseases by inhibiting tick infestation or reproduction. Subolesin is an antigenic molecule proven to be a potential tick vaccine against different tick species and even some tick-borne pathogens. However, its effectivity has not been verified in Haemaphysalis longicornis, which is a widely distributed tick species, especially in East Asian countries. Therefore, the purpose of this study was to evaluate the effectivity of subolesin vaccination against H. longicornis in a rabbit model. Methods Haemaphysalis longicornis (Okayama strain, female, adult, parthenogenetic strain) and Japanese white rabbits were used as the model tick and animal, respectively. The whole open reading frame of H. longicornis subolesin (HlSu) was identified and expressed as a recombinant protein using E. coli. The expression was verified using sodium dodecyl sulfate polyacrylamide gel electrophoresis, and the immunogenicity of rHlSu against anti-H. longicornis rabbit serum was confirmed using Western blotting. After vaccination of rHlSu in rabbits, experimental infestation of H. longicornis was performed. Variables related to blood-feeding periods, pre-oviposition periods, body weight at engorgement, egg mass, egg mass to body weight ratio, and egg-hatching periods were measured to evaluate the effectiveness of subolesin vaccination. Results The whole open reading frame of HlSu was 540 bp, and it was expressed as a recombinant protein. Vaccination with rHlSu stimulated an immune response in rabbits. In the rHlSu-vaccinated group, body weight at engorgement, egg mass, and egg mass to body weight ratio were statistically significantly lower than those in the control group. Besides, egg-hatching periods were extended significantly. Blood-feeding periods and pre-oviposition periods were not different between the two groups. In total, the calculated vaccine efficacy was 37.4%. Conclusions Vaccination of rabbits with rHlSu significantly affected the blood-feeding and reproduction in H. longicornis. Combined with findings from previous studies, our findings suggest subolesin has the potential to be used as a universal tick vaccine.![]()

Abstract
The porin gene is widely disseminated in various organisms and has a pivotal role in the regulation of pathogen infection in blood-sucking arthropods. However, to date, information on the porin gene from the Haemaphysalis longicornis tick, an important vector of human and animal diseases, remains unknown. In this study, we identified the porin gene from H. longicornis and evaluated its expression levels in Babesia microti-infected and -uninfected H. longicornis ticks at developmental stages. We also analyzed porin functions in relation to both tick blood feeding and Babesia infection and the relationship between porin and porin-related apoptosis genes such as B-cell lymphoma (Bcl), cytochrome complex (Cytc), caspase 2 (Cas2), and caspase 8 (Cas8). The coding nucleotide sequence of H. longicornis porin cDNA was found to be 849 bp in length and encoded 282 amino acids. Domain analysis showed the protein to contain six determinants of voltage gating and two polypeptide binding sites. Porin mRNA levels were not significantly different between 1-day-laid and 7-day-laid eggs. In the nymphal stage, higher porin expression levels were found in unfed, 12-h-partially-fed (12 hPF), 1-day-partially-fed (1 dPF), 2 dPF nymphs and nymphs at 0 day post-engorgement (0 dAE) vs. nymphs at 2 dAE. Cytc and Cas2 mRNA levels were higher in 2 dPF nymphs in contrast to nymphs at 2 dAE. Porin expression levels appeared to be higher in the infected vs. uninfected nymphs during blood feeding except at 1 dPF and 0–1 dAE. Especially, the highest B. microti burden negatively affected porin mRNA levels in both nymphs and female adults. Porin knockdown affected body weight and Babesia infection levels and significantly downregulated the expression levels of Cytc and Bcl in H. longicornis female ticks. In addition, this study showed that infection levels of the B. microti Gray strain in nymphal and female H. longicornis peaked at or around engorgement from blood feeding to post engorgement. Taken together, the research conducted in this study suggests that H. longicornis porin might interfere with blood feeding and B. microti infection.

Abstract
Haemaphysalis longicornis is a tick and a vector of various pathogens, including the human pathogenetic Babesia microti. The objective of this study was to identify female H. longicornis genes differentially expressed in response to infection with B. microti Gray strain by using a suppression subtractive hybridization (SSH) procedure. A total of 302 randomly selected clones were sequenced and analyzed in the forward subtracted SSH cDNA library related to Babesia infection, and 110 clones in the reverse cDNA library. Gene ontology assignments and sequence analyses of tick sequences in the forward cDNA library showed that 14 genes were related to response to stimulus or/and immune system process, and 7 genes had the higher number of standardized sequences per kilobase (SPK). Subsequent real-time PCR detection showed that eight genes including those encoding for Obg-like ATPase 1 (ola1), Calreticulin (crt), vitellogenin 1 (Vg1) and Vg2 were up-regulated in fed ticks. Compared to uninfected ticks, infected ticks had six up-regulated genes, including ola1, crt and Vg2. Functional analysis of up-regulated genes in fed or Babesia-infected ticks by RNA interference showed that knockdown of crt and Vg2 in infected ticks and knockdown of ola1 in uninfected ticks accelerated engorgement. In contrast, Vg1 knockdown in infected ticks had delayed engorgement. Knockdown of crt and Vg1 in infected ticks decreased engorged female weight. Vg2 knockdown reduced B. microti infection levels by 51% when compared with controls. The results reported here increase our understanding of roles of H. longicornis genes in blood feeding and B. microti infection.

Abstract
Antiviral immunity in Drosophila involves RNA interference and poorly characterized inducible responses. Here, we showed that two components of the IMD pathway, the kinase dIKKβ and the transcription factor Relish, were required to control infection by two picorna-like viruses. We identified a set of genes induced by viral infection and regulated by dIKKβ and Relish, which included an ortholog of STING. We showed that dSTING participated in the control of infection by picorna-like viruses, acting upstream of dIKKβ to regulate expression of Nazo, an antiviral factor. Our data reveal an antiviral function for STING in an animal model devoid of interferons and suggest an evolutionarily ancient role for this molecule in antiviral immunity.

Abstract
Filth flies, especially house fly, Musca domestica L., not only is a nuisance pest, but also acts as an important mechanical vector for pathogenic microorganism agents, including bacteria, protozoa, worms, fungi and viruses amongst humans and animals. More than 100 pathogens are associated with the house fly and bacteria have been isolated from feces, vomits, external surfaces, and internal organs of this species (De Vos V, et al., 1998; Dragon, DC, 1995; West, 1951; Markus, 1980; Kasprzak et al, 1981; Akinboade et al., 1984; Iwasa et al., 1999).The aim of this study was to detect pathogenic bacteria from house fly by UP-M-PCR. In this study, totally 267house flies were collected and we tried to find a procedure enabling the detection of three pathogens namely, Escherichia coli, Listeria monocytogenes, Salmonella spp and employed for multiplex PCR analysis in house fly. The most common isolated bacteria were L. monocytogenes(132 cases: 49.4%) and another isolated bacteria belong to E. coli (114 case: 42.6%) and Salmonella spp (98 cases: 36.7%). The results of the current study confirm that flies are much more than a nuisance and that they pose potentially serious health risks. The epidemiologic potential of house flies to disseminate pathogenic bacteria may be greater than initially suspected.Mongolian Journal of Agricultural Sciences Vol.15(2) 2015; 27-32

Abstract
For effective control of pathogen-transmitting mosquitoes, precise surveillance data of mosquito distribution are essential. Recently, an increase of insecticide resistance due to the kdr mutation in Anopheles gambiae, a mosquito that transmits the malaria parasite, has been reported. With the aim of developing a simple and effective method for surveying resistant mosquitoes, LAMP was applied to the allele-specific detection of the kdr gene in An. gambiae. Allele-specific LAMP (AS-LAMP) method successfully distinguished the kdr homozygote from the heterozygote and the wild type. The robustness of AS-LAMP suggests its usefulness for routine identification of insects, not only mosquitoes but also other vectors and agricultural pests. Here we describe the method of AS-LAMP to detect mutation in Anopheles mosquitoes.

Abstract
Vector-borne diseases, such as malaria and lymphatic filariasis, are co-endemic in large parts of the world. To develop a multiplex amplification method for the simultaneous detection of multiple insect-borne infectious diseases, we used LAMP with fluorescently labeled primers to identify the SPECT2 gene of Plasmodium berghei and the cytochrome oxidase subunit I gene of Dirofilaria immitis in mosquitoes. This technique could detect as few as 100 P. berghei-infected red blood cell-equivalents or one D. immitis microfilaria. Moreover, individual species of parasites in mosquitoes could be identified when a mixture of fluorescently labeled primer sets was used. These findings suggest that the multiplex LAMP assay is sensitive and specific enough to identify parasite-bearing mosquitoes in areas where several diseases occur simultaneously. This procedure could increase the efficiency and effectiveness of arthropod-borne disease elimination programs.

Abstract
Genetic variation in susceptibility to pathogens is a central concern both to medicine and agriculture and to the evolution of animals. Here, we have investigated the link between such natural genetic variation and the immune response in wild-type Drosophila melanogaster, a major model organism for immunological research. We found that within nine wild-type strains, different Drosophila genotypes show wide-ranging variation in their ability to survive infection from the pathogenic bacteria Listeria monocytogenes. Canton-S, a resistant strain, showed increased capacity to induce stronger innate immune activities (antimicrobial peptides (AMPs), phenol oxidase activity, and phagocytosis) compared to the susceptible strain (white) at early time points during bacterial infection. Moreover, PGRP-LE-induced innate immune activation immediately after infection greatly improves survival of the susceptible strain strongly suggesting a mechanism behind the natural genetic variation of these two strains. Taken together we provide the first experimental evidence to suggest that differences in innate immune activity at early time points during infection likely mediates infection susceptibility in Drosophila.
