Description
Puccinia triticina isolates from North Caucasus and Leningrad region were compared in regard to the genetic structure, phenotypic composition as well as frequency of occurrence of RAPD-phenotypes and polymorphous major fragments with the help of Rogers index. Did not demonstrate any significant differences according to their genetic structure and occurrence of major fragments of DNA-polymorphism. The difference of isolates from given regions was determined with high degree of confidence according to the phenotypes of virulence and RAPD-phenotypes

DETECTION OF SEROTYPE SPECIFICITY OF AFRICAN SWINE FEVER VIRUS NON-HAEMADSORBING STRAINS
DescriptionGamma irradiation-inactivated cultural preparations (-IP) of African swine fever (ASF) non-haemadsorbing strains acquire a potential for haemadsorption induction in porcine bone marrow culture (PBMC). We have obtained some experimental data indicating that a modification of haemadsorption inhibition assay (HIA) which is an assay aimed at “removal” of γ -IP-induced haemadsorption may be used in research works to determine serospecificity rates of ASF virus non-haemadsorbing isolates

ANTICELLULAR EFFECTORS OF IMMUNITY AT AFRICAN SWINE FEVER
DescriptionSome optimal conditions to fix virus-specific anticellular effectors of immunity at African swine fever (ASF) were determined. Injection of an attenuated strain FK-135 at high doses enables registration of antibodies active in antibody-dependent cellular toxicity (ADCT) and primary cytotoxic T-lymphocytes (CTL) on days 3 and 6, respectively. After infection of pigs with a virulent strain F-32 not any immunity anticellular effectors were found
