Complete genome sequencing of three Tamdy (TAMV) virus strains was carried out. The prototype strain TAMV/LEIV-1308Uz was isolated for the very first time from the Hyalomma asiaticum asiaticum Schülce et Schlottke, 1929 (Ixodidae, Hyalomminae) collected in the August 1971 from sheep in the arid area near Namdybulak town (41 degrees 36' N, 64 degrees 39' E) in the Tamdinsky district of the Bukhara region (Uzbekistan). TAMV was revealed to be a prototype member of the new phylogenetic group within the limits of the Nairovirus...

Complete and partial genome sequences of two isolates of an unusual new plant virus, designated Donkey orchid symptomless virus (DOSV) were identified using a high-throughput sequencing approach. The virus was identified from asymptomatic plants of Australian terrestrial orchid Diuris longifolia (Common donkey orchid) growing in a remnant forest patch near Perth, western Australia. DOSV was identified from two D. longifolia plants of 264 tested, and from at least one plant of 129 Caladenia latifolia (pink fairy orchid) plants tested...

The role of migratory birds in circulation tick-borne viruses needs to be better defined. In order to assess the potential role of migratory birds in exotic virus spread, we conducted a study to identify ticks collected from migratory birds in the Central Region of Italy, and performed molecular investigation for Crimea-Congo Hemorrhagic Fever (CCHFV), West Nile fever (WNFV) and Usutu (USUV) in the vectors. A total of 137 competent ticks were collected with predominance of Hyalomma species. Although, negative results were obtained for all viruses considered, the high proportion of Hyalomma ticks highlights the potential risk for the dissemination of tick-borne viruses through infested migratory birds...

The Armed Forces Health Surveillance Center, Division of Global Emerging Infections Surveillance and Response System Operations (AFHSC-GEIS) initiated a coordinated, multidisciplinary program to link data sets and information derived from eco-climatic remote sensing activities, ecologic niche modeling, arthropod vector, animal disease-host/reservoir, and human disease surveillance for febrile illnesses, into a predictive surveillance program that generates advisories and alerts on emerging infectious disease outbreaks...

The 9th annual meeting of the Italian Society for Virology (SIV) comprised seven plenary sessions focused on: General virology and viral genetics; Virus-Host interaction and pathogenesis; Viral oncology; Emerging viruses and zoonotic, foodborne, and environmental pathways of transmission; Viral immunology and vaccines; Medical virology and antiviral therapy; Viral biotechnologies and gene therapy. Moreover, four hot topics were discussed in special lectures: the Pioneer in human virology lecture regarding the control of viral epidemics with particular emphasis on the human immunodeficiency virus (HIV), the Pioneer in plant virology lecture focused on cell responses to plant virus infection, a Keynote lecture on the epidemiology and genetic diversity of Crimea-Congo Hemorrhagic Fever virus, and the G...

A seroepidemiology survey of nine zoonoses was carried out in 2007 on 90 healthy adult volunteers in Viljujsk, a northern city in the Republic of Sakha (Eastern Siberia). The seroprevalence of Lyme borreliosis was 3.3% by immunofluorescence. None of the subjects displayed a positive enzyme-linked immunosorbent assay/Western blot result for alveolar or cystic echinococcosis. The seroprevalence of toxocariasis by Western blot was 4.4%, and 8.9% of the subjects had anti-Toxoplasma IgG. By enzyme-linked immunosorbent assay, the seroprevalence of trichinellosis was 4...

Crimea-Congo haemorrhagic fever is a tick-borne viral zoonosis with the potential of human-to-human transmission. The disease occurs in extensive areas in Asia, South-eastern Europe and Africa. Haemorrhagic manifestations constitute a prominent symptom of the late disease stage, with case fatality rates from 9 to 50%. The recent increase in the number of cases in Eastern Europe and the potential for nosocomial outbreaks indicate the advisability of diagnosis in every patient hospitalized in Italy with haemorrhagic fever...

In 2008, several publications have highlighted the role of climate change and globalization on the epidemiology of infectious diseases. Studies have shown the extension towards Europe of diseases such as Crimea-Congo fever (Kosovo, Turkey and Bulgaria), leismaniosis (Cyprus) and chikungunya virus infection (Italy). The article also contains comments on Plasmodium knowlesi, a newly identified cause of severe malaria in humans, as well as an update on human transmission of the H5NI avian influenza virus. It also mentions new data on Bell's palsy as well as two vaccines (varicella-zoster and pneumococcus), and provides a list of recent guidelines for the treatment of common infectious diseases...

Complete S-segment nucleotide sequences of genomic RNA were determined for two Crimea-Congo hemorrhagic fever (CCHF) virus strains, i.e. LEIV 10145 Uz isolated from ticks in Uzbekistan, 1985, and LEIV 29223 Stv isolated from a patient in Stavropol region, 2000. It was established that the S-segment length is 1672 and 1674 nucleotides. Therefore, the initiating codon (for methionine) is located at positions 56-58; the length of translation frames for the nucleocapsid protein is 482 amino acid residues. Distinctions in the length of S-segment, as compared to other strains, are related only with the 5' and 3' non-coding regions...

In Azerbaidjan, a rural province in the North-West of Iran, an hemorragic fever has been described, with a seasonal occurrence, mainly in July. it is characterized with the penia and thrombocytopenia. Its identification with the hemorragic fever of Crimea-Congo has been ruled out on clinical and biological arguments. In a new survey, fever appeared to be generally moderate or absent and the clinical aspect is that of a thrombocytopenic purpura. The role of a virus transmitted by tick, and a toxic etiology have been both suspected but not proved...
