The study provides the results of avian influenza virus surveillance in Central Asia during 2003-2009. We have analyzed 2604 samples from wild birds. These samples were collected in Kazakhstan (279), Mongolia (650), and Russia (1675). Isolated viruses from samples collected in Mongolia (13 isolates) and in Russia (4 isolates) were described. Virological analysis has shown that six isolates belong to the H3N6 subtype and five isolates belong to the H4N6 subtype. Two H1N1 influenza viruses, one H10N7 virus, two H3N8 viruses, and an H13N8 virus that is new for Central Asia have been also isolated. Samples were taken from birds of six orders, including several species preferring water and semiaquatic biotopes, one species preferring dry plain regions, and one more species that can inhabit both dry and water biotopes. © 2012 American Association of Avian Pathologists.

Ticks and Tick-borne Diseases | Year: 2012

Since the year 2005, clinical patterns resembling tick-borne rickettsioses have been noticed in Mongolia. Epidemiological data regarding species of the aetiological agent, tick vector, prevalence, and distribution as well as incidence of human cases throughout Mongolia are still sparse to date. In order to identify Rickettsia species occurring in Mongolia, we investigated Dermacentor nuttalli (n=179) and Ixodes persulcatus (n=374) collected in 4 selected provinces. Rickettsia raoultii was the predominant Rickettsia (82% prevalence) found in D. nuttalli and was also detected in I. persulcatus (0.8%). The Rickettsia prevalence in D. nuttalli from different provinces varied between 70% and 97%. In addition, R. sibirica was identified in approximately 4% of D. nuttalli, but solely from Arkhanghai province. The results of this study extend the common knowledge about the geographic distribution of R. raoultii and its high prevalence in D. nuttalli. Although the pathogenicity of this Rickettsia is still unclear, it should be considered in Mongolian patients suspected of having tick-borne rickettsiosis. © 2012 Elsevier GmbH. Source

The Asia Pacific Strategy for Emerging Diseases (APSED) requires collaboration, consensus, and partnership across all the different actors and sectors involved in different aspects of emerging disease. Guided by APSED, Mongolia has established a functional coordination mechanism between the animal and human health sectors. Surveillance, information exchange and risk assessment, risk reduction, and coordinated response capacity and collaborative research have been identified as the four pillars of the zoonoses framework. Intersectoral collaboration has been clearly shown to be a crucial tool in the prevention and control of emerging zoonotic diseases. A "One Health" strategy has been implemented under the concept of 'Healthy animal-Healthy food-Healthy people'. An intersectoral coordination mechanismestablished between the veterinary and public health sectors has expanded its function to incorporate more work on food safety, emergency management, and effects of climate change on zoonotic diseases. Its membership includes the human health sector, the veterinary sector, the national emergency management agency, the environment sector, emergency management and inspection authorities, and the World Health Organization (WHO). The main outputs of the coordination mechanism have been strengthened surveillance and response activities and laboratory capacities. The coordination mechanism has also strengthened the surveillance and response capacity of neglected zoonotic diseases, such as brucellosis, anthrax, and tick-borne diseases. Through regular meetings and brainstorming sessions, both sectors have developed joint operational plans, a long-term risk reduction plan 2011-2015, initiated a prioritization exercise and risk assessment for 29 zoonotic diseases, and reviewed and revised standards, procedures, and communication strategies. In 2011, a list of experts onmajor zoonoses were identified fromdifferent sectors and formed into a taskforce to identify the focal points for rabies, brucellosis, and vector-borne diseases.As a result, disease control strategies are nowlinked to scientific research and epidemiological expertise. © 2012 Springer-Verlag Berlin Heidelberg.

The incidence of anthrax, which is caused by Bacillus anthracis, in the human and animal population of Mongolia has increased recently, and control of this infection is a nationwide concern. In this study, 29 isolates obtained from animals and various regions in Mongolia from 2001 to 2007 were analyzed by performing multiple-locus variable-number tandem-repeat analysis for 8 loci (MLVA-8) to understand the genetic relationship between the Mongolian B. anthracis isolates. We found that all the Mongolian isolates can be classified into A3 cluster along with the Japanese and the Chinese B. anthracis isolates. Our data revealed that MLVA-8 is useful for studying the molecular epidemiology of the Mongolian B. anthracis isolates and would help characterize B. anthracis infections in Mongolia. Source

In Mongolia, Lyme borreliosis was first reported in 2003. To determine which Borrelia species may contribute to the occurrence of Lyme borreliosis in Mongolia, real-time PCR was conducted on 372 adult Ixodes persulcatus ticks collected in Selenge Aimag, the province with the highest incidence of human Lyme borreliosis. 24.5% of ticks were identified to be positive for Borrelia burgdorferi sensu lato DNA. Species differentiation using an SNP-based real-time PCR and multi-locus sequence analysis revealed that strains phylogenetically closely related to B. bavariensis (previously known as B. garinii OspA serotype 4) is the most prevalent species, showing an unexpectedly high genetic diversity. © 2012 Elsevier GmbH.
