Different species of ticks were found, in the territories of Kazakhstan and Tajikistan, to be infected with the virus of Crimean-Congo hemorrhagic fever (CKHF). The virologic evaluation included determination of antigen and RNA of the CKHF virus by ELISA and RT-PCR, respectively. The below tick species were found to be involved in the epidemic process:(More)
A retrospective cohort analysis was conducted in Kazakhstan to define modifiable risk factors during seven outbreaks of human anthrax. Fifty-three cases and 255 non-ill persons with an epidemiologic link to an infected animal were enrolled. Cases were 58% male and had a median age of 35 years (range = 5-71). Nearly all cases had cutaneous disease (96%). Two(More)
Serum samples from all patients with culture-confirmed brucellosis including those with chronic disease from Kazakhstan tested positive in the serum agglutination test for titers > or = 1:25 and reacted in the Brucella immunoglobulin M/immunoglobulin G lateral flow assay (LFA) confirming the high sensitivity of these assays. The strong reactivity in the LFA(More)
Sera samples from patients suspected of Crimean-Congo hemorrhagic fever (CCHF) taken during epidemic outbreak at the territory of Sarysusky and Moiynkumsky districts of the Zhambyl region in Kazakhstan, in 2000, were analysed by means of reverse transcription-polymerase chain reaction (RT-PCR) and sequencing of virus genome fragments. Genome RNA of CCHF(More)
Combinations of conventional serological methods and new ELISA procedures were evaluated to develop the most efficient and effective diagnostics for the detection of brucellosis in humans and animals. Sera from humans (n=249) and animals (n=99) were collected from brucellosis endemic areas (Zhambyl district and Enbekshi-Kazakh district of Almaty region in(More)
We evaluated Crimean-Congo hemorrhagic fever (CCHF) surveillance data from southern Kazakhstan during 2009-2010 and found both spatial and temporal association between reported tick bites and CCHF cases. Public health measures should center on preventing tick bites, increasing awareness of CCHF signs and symptoms, and adopting hospital infection control(More)
A total of 46 cases of wolves attacking people were registered in the Aktyubinsk region during the period of 1972--1976. These attacks resulted in 1 person dying of wounds and 2 persons being infected with rabies. In more than a half of the wolves available for examination after the attack rabies was confirmed by laboratory investigation. All the victims of(More)
The aim of the work is the comparison of the epidemiology of influenza and acute respiratory virus infections (ARVI) in the Republic of Kazakhstan with the corresponding influenza epidemic in Russia induced by influenza pandemic virus A/California/07/2009 in 2009. Data on influenza and ARVI from the Republic of Kazakhstan and Federal Center of influenza was(More)
Blood specimens obtained from 32 CCHF patients were tested for the presence of CCHF virus markers. In addition, 3210 ticks of the genera Hyalomma asiaticum, Hyalomma anatolicum, and Dermacentor niveus were examined to identify the CCHF virus antigen and RNA. This material was obtained during the 2001-2003 local outbreaks of CCHF in Kazakhstan and(More)
