[Wild small mammals are the reservoir hosts of the Bartonella genus bacteria in the south of Moscow region].

A total of 103 blood samples collected from wild small mammals captured in the Prioksko-Terrasny Reserve on the south of Moscow region were studied to determine the bartonellae prevalence. The examined species were the yellow-necked mice Apodemus flavicollis (35 samples), the European wood mouse Apodemus uralensis (10 samples), the bank vole Clethrionomys glareolus (51 samples), the house mouse Mus musculus (3 samples), the common vole Microtus arvalis (2 samples), and the shrew Sorex araneus (2 samples). Initially, we obtained 76 bacterial Bartonella-like isolates after plating onto the surface of the solid nutrient media.

[The ecological aspects of the epidemiology of hemorrhagic fever with renal syndrome in the south of the Far East in Russia].

The data on the relationship between the epizootic process in the population of mice (the source of Hantavirus infection) and the seasonal manifestations of morbidity in hemorrhagic fever with renal syndrome (HFRS) in the southern region of the Russian Far East are presented. The asynchronous course of the epizootic process in the population of rodents causes irregularity in the spread of HFRS in the region and periodicity in the appearance of foci. Seasonal rises in HFRS morbidity coincide with the activity of the epizootic process in the population of mice: spring-summer rises with an increase in the number of infected rodents in the populations of large Japanese field mice and autumn-winter rises in voles.

[The role of Hantaan virus serotypes in the etiology of hemorrhagic fever with renal syndrome in the Far East of the USSR].

The employment of two serological tests (indirect fluorescence antibody technique and neutralization test) demonstrated the leading role of Hantaan virus serotype 1 strains isolated from field mice in the pattern of the incidence of hemorrhagic fever with renal syndrome (HFRS). Proofs of the etiological importance of strains of serotypes 3 and 5 occurring in brown rats and Cl. rufocanus were obtained.

[Effect of pikamilon on the cortical blood supply and microcirculation in the pial arteriole system].

Pikamilon was shown to increase blood supply in cerebral cortex in conscious rats and rabbits. The increase in blood flow has been revealed under intravenous, intraperitoneal and systemic administration of the drug. There is a pronounced dilatation of pial arterioles under pikamilon action while applied locally.
