Isolation of two strains of West Nile virus during an outbreak in southern Russia, 1999.

From July to September 1999, a widespread outbreak of meningoencephalitis associated with West Nile virus (Flavivirus, Flaviviridae) occurred in southern Russia, with hundreds of cases and dozens of deaths. Two strains of West Nile virus isolated from patient serum and brain-tissue samples reacted in hemagglutination-inhibition and neutralization tests with patients' convalescent-phase sera and immune ascites fluid from other strains of West Nile virus

Содержание радионуклидов ¹³⁷Cs, ⁴⁰K, ⁹⁰Sr, ²¹⁰Po и ряда химических загрязнителей в черноморских мидиях Mytilus galloprobvincialis Lam.

Концентрации радионуклидов 90Sr, 137Cs, 210Ро, полихлорбифенилов и ртути, определенные в мидиях Черного моря, собранных в четырех разных бухтах побережья Крыма, зависели от мест отбора проб, длины раковин моллюсков и стадий развития их гонад. Исследование выполнено в рамках программы CIESM “Mussel Watch”.The concentrations of 137Cs, 40K, 90Sr, 210Ро radionuclides, mercury and polychlorbiphenyls were determined in the Black Sea mussels collected in four different areas of the Crimean coast depending on places of sampling, the shell length of mollusks and the stages of their gonads development. The study was carried out in the framework of CIESM “Mussel Watch” Programme
