The first cluster of hemorrhagic fever with renal syndrome (HFRS) in Poland was identified in 2007 in the Subcarpathian region. The natural environment of this area is a key habitat for hantavirus vectors. The animal reservoir of existing human HFRS clusters was studied to assess the occurrence of viruses (including Tula virus, Puumala virus, and(More)
The aim of this study was to investigate the in vitro cytotoxicity of oseltamivir derivatives and determine their activity against A/H1N1/PR/8/34 and A/H3N2/HongKong/8/68 - strains of influenza virus. Antiviral activity of these compounds was determined by using two methods. MTT staining was used to assess the viability of MDCK cells infected with influenza(More)
The aim of this study was to conduct an epidemiological and laboratory surveillance of Influenza-Like Illnesses (ILI) in Polish Armed Forces, civilian military personnel and their families in 2011/2012 epidemic season, under the United States Department of Defense-Global Emerging Infections Surveillance and Response System (DoD-GEIS). ILI incidence data(More)
Viral hemorrhagic fevers are severe zoonotic diseases caused by RNA-viruses classified into 4 families: Arenaviridae, Bunyaviridae, Filoviridae, and Flaviviridae. They are present on all continents except Antarctica, their person-to-person spread is easy, and there is a high risk of them being used as weapon by bioterrorists. So far, efforts to develop(More)
INTRODUCTION In the autumn of 2009 the authors participated in a humanitarian operation in Western Ukraine by undertaking an epidemiological investigation of an influenza-like-illness (ILI) in the L'viv Oblast region. Mobile biological survey teams took samples from civilian patients with severe acute respiratory distress syndrome, rapid transportation of(More)
Although smallpox was eradicated over 30 years ago, the disease remains a major threat. High mortality, high infectivity and low resistance of the contemporary population make the smallpox virus very attractive to terrorists. The possible presence of illegal stocks of the virus or risk of deliberate genetic modifications cause serious concerns among(More)
The efficiency of peptides against many species of bacteria, fungi and parasites has been widely described. Recent studies on peptides have also demonstrated their antiviral activity. Some peptides exhibit direct virucidal activity, others disturb attachment of virus particles to the cell membrane surface or interfere with intracellular replication of(More)
Tularemia is highly infectious and fatal zoonotic disease caused by Gram negative bacteria Francisella tularensis. The necessity to undergo medical treatment in early phase of illness in humans and possibility of making use of bacterial aerosol by terrorists in an attack create an urgent need to implement a rapid and effective method which enables to(More)
Influenza is a contagious respiratory disease caused by viruses belonging to the family Ortomyxoviridae. Among the influenza viruses type A, B and C, the A type virus shows the most pathogenic potential. Its surface receptor glycoproteins, hemagglutinin (HA) and neuraminidase (NA), are characterized by high antigenic variation, thus a host organism cannot(More)
