[Impact of influenza epidemics on cardiovascular disease mortality]. / Izuchenie vliianiia épidemii grippa na smertnost' ot serdechno-sosudistykh zabolevanii.

The study data indicated that the reduced epidemics of influenza over the period from 1975 to 1986 did not have any impact on the dynamics of general mortality and mortality from the main types of cardio-vascular diseases among population of Minsk.

[Isolation of influenza A viruses with a new antigenic formula from wild birds]. / Izoliatsiia virusov gripopa A s novoi antigennoi formuloi ot dikikh ptits.

Three hemagglutinating agents were isolated from mixed pools of the viscera from black-headed gulls (Larus ridibundus) and robin (Erithacus rubecula) collected in the Byelorussian SSA and the Kaliningrad region of the RSFSR. Typing of the viruses by double immunodiffusion technique revealed antigenic relationships of the viruses with swine hemagglutinin (Hsw1) and human hemagglutinin H0. One of the strains had neuraminidase N2 the other two Nav2. An analysis of the polypeptide composition of the virus showed the molecular weights of the heavy (HA1) and light (HA2) hemagglutinin chains to be similar in both strains (about 50,000 and 25,000 daltons, respectively). The strains had a low content of the light hemagglutinin chain (HA2) which is typical for viruses having Hsw1 hemagglutinin.

[Classical fowl plague virus reproduction in the body of Aedes aegypti mosquitoes]. / Reproduktsiia virusa istinnoi chumy ptits v organizme komarov Aedes aegypti.

The results of the studies on fowl plague virus (FPV, Rostok strain) reproduction in Aedes aegypti mosquitoes are presented. The virus-containing allantoic fluid was inoculated intrathoracally in volumes of 0.1 and 0.2 microliter. The virus was isolated in chick embryos and could be detected at 5--14 days after inoculation. After inoculation of 0.1 microliter of virus it could be detected in doses of 0.5, 2.0, 1.75 Ig2 ID50, after inoculation of 0.2 microliter--in doses of 5, 1.5, and 0.5 Ig2 ID50.
