Molecular and seroepidemiological investigation of Сoxiella burnetii and spotted fever group rickettsiae in the southern region of Kazakhstan.

Ticks are involved in the circulation of a number of human pathogens, including spotted fever group (SFG) Rickettsia spp. and Coxiella burnetii. Little is known about the occurrence of these microorganisms in the southern region of Kazakhstan.

Molecular and serological survey of bovine viral diarrhea virus infection in cattle in Kazakhstan.

The aim of this study was to estimate the occurrence of bovine viral diarrhea virus (BVDV) infection and to assess the population immunity in cattle vaccinated against BVDV in different regions of Kazakhstan. Cattle samples were collected in 12 oblasts (43 districts) of Kazakhstan. A total of 2477 cattle from 114 herds and 21 Bukhara deer (Cervus elaphus bactrianus) were examined by ELISA and conventional RT-PCR.

Prevalence and genetic diversity of coronaviruses, astroviruses and paramyxoviruses in wild birds in southeastern Kazakhstan.

Wild birds are natural reservoirs of many emerging viruses, including some zoonoses. Considering that the territory of Kazakhstan is crossed by several bird migration routes, it is important to know pathogenic viruses circulating in migratory birds in this region. Therefore, the aim of this study was to identify the host range, diversity and spatial distribution of avian paramyxoviruses, coronaviruses, and astroviruses in free-ranging wild birds in the southeastern region of Kazakhstan.

Identification and characterization of bluetongue virus in Culicoides spp. and clinically healthy livestock in southeastern Kazakhstan.

Objective: Bluetongue is an arthropod-borne disease of ruminants. Here, we investigated the seroprevalence of bluetongue virus (BTV) in livestock and performed the first genetic characterization of BTV isolated from sheep and Culicoides midges in the southeastern region of Kazakhstan.

Methods: Blood samples were collected from 1241 asymptomatic livestock.
