Field Epidemiology Training Programmes (FETPs), which are modelled after the Centers for Disease Control and Prevention’s Epidemic Intelligence Service programme, began in 1980 and have produced graduates in more than 70 countries, including 12 in the Western Pacific Region.1,2 These programmes aim to “build sustainable capacity for detecting and responding to public health threats” and “develop expertise so that disease outbreaks can be detected locally and prevented from spreading”.3 FETPs thus include training in applied epidemiology and public health services. FETP trainees and graduates, however, often have additional responsibilities: mentoring newer trainees, supervising in the field, leading short training courses, facilitating meetings, etc. Programmes therefore must provide trainees with the knowledge and skills to fulfil these responsibilities.

BackgroundThere are 137 soums of 17 provinces have plague foci in Mongolia. The 51.7% of them is case, 23.4%- low, 9.5% - high, 0.7% - hyper active. Main host of plague foci is marmot in Mongolia. According last20 year’s surveillance study, about 75.5% of Y.pestis was isolated from marmot, marmot carcassesand their flea. Human plague cases has been caused illegal hunting marmot in Mongolia. Even legaldocument which prohibited marmot hunting was appeared since 2005, people has been hunting marmotfor selling marmot meat, skin and other products. It is depends economy crises and other public issues inMongolia. Also influenced increase risk of human plague and being reverse result in plague preventionactivities.Materials and MethodsStudy was used data of rodent for zoonotic diseases suspicious which tested plague in National centerfor zoonotic disease (NCZD) in 2005-2015 and 13 local center for zoonotic diseases in 1988-2015. Datawas kept in NCZD and National archival authority. For mapping we used Arc View 3.2.ResultsTotally 397 event information of suspicious rodents and other animals was received in NCZD from 8 districtsof Ulaanbaatar city in 2002-2015. Most of information was received from Songinokhairkhan-64.2%district and smallest number was from Nalaikh district-0.3%. 92.2% of them were marmot, 0.1% of themwere marmot raw products for treatment purpose. Totally 1285 animal samples were tested by plaguedisease and the result was negative. Five hundred thirty tree marmots were carried to Ulaanbaatar from10 provinces. In that time plague foci were active and Y.pestis was isolated in provinces which marmotwas carried to Ulaanbaatar.In 1988-2015, totally 257 marmots and animals of 515 event information was received in15 provinces.Including 13.2% of them were birds, 84% of them marmot, 1.6% of them were livestock, 1.2% of themother animals. About 216 marmots were tested by plague. 51.2% of them were detected positive results.We develop conclusion based laboratory investigation result even it need high cost to take earlyprevention and response measures.Conclusion1. It is high risk to spread plague by carrying suspicious animal in urban area. Therefore, it is importantto take early response measures even it high cost. In further, increase cost and support rapid test ofhigh technology.2. To organize rational advertisement and increase knowledge of population about not doing illegalhunting, not selling marmot raw products in urban area, not using marmot raw products for treatmentuse and avoid contact with marmot carcasses.3. It is important to cooperate joint response measures with policeman, inspection agency andveterinary and human health sectors in Mongolia.

BACKGROUND: Toll like receptors (TLRs) are a class of proteins that key role in the innate immune system. TLR7 is expressed on monocytes, macrophages and dendritic cells, T cell, B cell and eosinophiles. TLR7, originally identified as recognizing imidaquinoline, loxibrine, broprimine and ssRNA, ssRNA viruses such as vesicular stomatitis virus, influenza A virus and human immunodefiency virus. It is known that virus ssRNA affects signaling molecule of IFN-y. Objective: To determine gene and protein activation of IFN-y signal transduction by TLR7 ligand in the endothelial cells.
MATERIAL: In study we used mouse aortic linear endothelial cell which is cultured (END-D) in 5% heat- inactivated fetal calf serum (FCS), medium (DMEM) containing antibiotic mix(penicillin G, streptomycin, amphotericin B) at 37°C (5% CO2). Endothelial cells treated with synthetic IFN-γ and imiquimodligands, then the NO (nitric oxide) concentration in the supernatant is determined by Griess reagent. Endothelial cells are cultured in 6 well cell culture plate and in each well 2*104cells are expected to be grown for 24 hours of culture. Then, the cells are treated with synthetic IFN-γ and имиквимод ligand for 6 hours and the NO signaling gene activation iNOS mRNA expression which is induced by IFN-γ is determined by RT-qPCR. Endothelial cells are cultured in 12 well cell culture plate and in each well 2*104 cells are expected to be grown for 18 hours of culture. Then, the cells are treated with synthetic IFN-γ and imiquimodligands for 24 hours and the NO signaling protein iNOS expression which is induced by IFN-γ is determined by western blotting. The experiment was conducted as representation mean of at least three test results. The difference between statistical probabilities is determined by the “Students” t test. The p<0.01 value is assumed to be statistically different.
RESULTS: TLR7 ligand imiquimodaugmented interferon gamma induced nitric oxide production TLR7 ligand imiquimodincreased interferon gamma induced iNOS mRNA gene expression. TLR7 ilgand imiquimodup-regulated interferon gamma induced iNOS protein expression.
CONCLUSIONS: TLR7 ligand imiquimod augments IFN-γ signaling in the endothelial cells. This synergistic effect has revealed in the levels of gene and protein expression.

Introduction:
When human body encounters external pathogens primary/innate immunity cells are activated by
recognizing them and secondary/adaptive immunity is activated consecutively. In our previous study,
we revealed that there is a synergistic action between TLR9 and IFN-γ signaling in the endothelial cells.
Purpose:
To determine the role of negative and positive regulator proteins on the IFN-γ/TLR9 signaling pathway.
Methods:
In this study, murine endothelial cell (END-D) culture was used. END-D cells pre-treated with TLR9
ligand CpG DNA and then stimulated with IFN-γ. The negative (SHP-2, SOCS1, PIAS1) and positive
(p38) regulator protein expression was detected by Western blotting.
Results and Conclusion
Treatment by TLR9 ligand CpG DNA and IFN-γ increased positive regulator p38 phosphorylation in 0.5
hour. CpG DNA inhibited IFN-γ negative regulator PIAS1 protein expression in 6 hour and SOCS1 and
SHP-2 expression could not affect in 4 hour.

Introduction:
Toll like receptors (TLRs) are a class of proteins that key role in the innate immune system. The SOCS1 and SHP2 proteins are negative-feed loop inhibitors of signaling of JAK/STAT and TLRs pathways.
Purpose:
To determine negative regulator protein activation which is activated through TLR7 ligand/IFN-γ signal transduction in endothelial cells.
Methods:
We used mouse aortic linear endothelial cell (END-D); protein expressio was detected by western blotting
Results:
We analyzed a time dependent stimulation effects of negative regulator proteins stimulated by TLR7 ligand/IFN-γ in endothelial cell cultures. Imiquimod of 10 μg/ml treatment of 1 hr was followed by 100 ng/ml IFN-γ stimulation for 1-8hr to analysis of negative regulator SOCS1 and SHP2 protein expression.
In untreated cells, there was low activations of negative regulator SOCS1 and SHP2 proteins. IFN-γ stimulation alone had increased SOCS1 and SHP2 protein expressions, also imiquimod treatment highly elevated SOCS1 and SHP2 expressions. However imiquimod and IFN-γ doubled treatment have decreased activation of negative regulator SOCS1 and SHP2 proteins. These findings suggest SOCS1 and SHP2 proteins are inhibitors in the TLR7 ligand/IFN-γ signaling.
Conclusion
Negative regulators, SOCS1 and SHP2 strongly suppressed activations of TLR7 ligand/IFN-γ signaling

Introduction:
The aim of this research project is to elucidate the crosstalk of innate and adaptive immune reactions against the DNA containing bacteria.
:
This study held in the Core laboratory, Science Technology Center, Mongolian National University of
Medical Sciences (MNUMS). Murine aortal endothelial cells, END-D cultured and the cell viability checked by MTT assay. In addition, the NO production, protein and gene expression studied by Griess Reagent
assay, R.T-PCR and immunoblotting, respectively.
Results:
0.1µM, 1µM and 10µM of TLR9 ligand exhibited no cytotoxic action against the cells by MTT assay. IFN-ү alone induced NO production in END-D cells. In the other hand, TLR9 ligand at 0.1µM, 1µM and 10µM up-regulated IFN-ү induced NO production in dose dependent manner. RTPCR results exhibit that TLR9 ligand up regulates iNOS mRNA. Immunoblotting analysis showed the enhanced iNOS protein expression and phosphorylation of STAT1 in cells pre-treated with TLR9 ligand.
Discussion:
We have demonstrated CpG DNA, TLR9 ligand, up-regulates IFN-ү induced NO via enhanced IFN-ү signaling. The result of Western Blotting and RT-PCR support the up-regulation of NO. CpG DNA can be used as agent against virus and bacteria. Further research need to be conducted.
Conclusion
TLR9 ligand, CpG DNA up-regulates IFN-ү induced NO production in time and dose dependent manner. TLR9 ligand augments the expression of iNOS mRNA and STAT1 phosphorylation in response to IFN-ү.
