Genetic polymorphism of the C4 component of human complement in the Slovak population.

The distribution of C4 phenotypes and gene frequencies were studied in 104 genetically unrelated persons of Slovakia using high-voltage agarose gel electrophoresis with subsequent immunofixation. Five C4A alleles and three C4B alleles were detected. The gene frequencies were as follows: A2 = 0.0576, A3 = 0.7644, A4 = 0.0336, A6 = 0.0625, AQ0 = 0.817, B1 = 0.7836, B2 = 0.1009, BQ0 = 0.1153. The C4AQ0 and C4BQ0 alleles established by densitometry appeared in the Slovak population in 16.34% and 23.07%, respectively.

Genetic polymorphism of factor B of the complement system (Bf) in the Slovak population.

The distribution of factor B (Bf) phenotypes and gene frequencies were investigated in 280 genetically unrelated persons of the Slovak population. Thin-layer agarose gel high-voltage electrophoresis and subsequent immunofixation were used. A low frequency of the "rare" allele BfFl was observed (BfFl = 0.0017). The frequencies of common Bf alleles BfS and BfF (BfS = 0.816, BfF = 0.1625) and a "rare" allele BfSO.7 (BfSO.7 = 0.0178) were inside the corresponding ranges of BfS, BfF and BfSO.7 found in European Caucasoids. No other variants were observed.

Pathogenesis of acute and persistent murine herpesvirus infection in mice.

Outbred laboratory mice were inoculated at the age of 5, 10 and 21 days by oral and/or intranasal routes with 2 different (a lethal and a nonlethal) doses of the murine herpesvirus isolate 68 (MHV-68). Severe exudative pneumonia with haematogenous dissemination of the virus to liver, heart muscle, and kidneys developed in the 5-day-old as well as in a part of the 10-day-old mice. Virus antigen was found by immunofluorescence (IF) in the alveolar lining of lungs, in heart muscle fibres, in spleen and thymic lymphocytes, in the tubular epithelium cells of kidneys, in the neurons of Gasserian ganglia and in the intima of large pulmonary vessels. Electron microscopy confirmed the transfer of virus particles through the capillary endothelium of the damaged alveolar septa. The surviving progeny and the mothers of animals, which had not succumbed to the lethal virus dose, were kept for 141-169 days when lungs and Gasserian ganglia were examined for virus presence. MHV-68 was recovered both by direct examination of the tissue homogenates as well as by the explantation technique. The results are suggestive for a dynamic persistence of MHV-68 rather than for static latency.

Experimental pathogenesis of murine herpesvirus in newborn mice.

Newborn white mice were susceptible to peroral (p.o.) infection with murine alphaherpesvirus isolated from free-living Clethrionomys glareolus. Death occurred within 6-8 days in animals infected with the higher virus dose of 4.8 log10 TCID50. Clinical symptoms also occurred in some animals infected with lower doses, while others developed inapparent infection as judged by presence of humoral antibodies at 60 days post-infection (p.i.). The virus was detected in the lungs, blood, liver, spleen, kidneys, heart muscle, brain and urinary bladder of sick animals. Necrotising pneumonia accompanied the replication of the virus in the epithelial cells of alveolar ducts and alveolar lining as confirmed by immunofluorescence and histological examination. Latent infection of Gasserian ganglia in the survivors was not necessarily related to the administered dose of infectious virus. Two of mother females, which had eaten their diseased offspring, became inapparently infected as proved by reisolation of the virus from trigeminal ganglion explants and by detection of specific antibodies at 60 days p.i.
