ABSTRACTPrevious studies have suggested that pneumococcal choline binding protein A (PcpA) is important for the full virulence ofStreptococcus pneumoniae, and its amino acid sequence suggests that it may play a role in cellular adherence. PcpA is under the control of a manganese-dependent regulator and is only expressed at low manganese concentrations, similar to those found in the blood and lungs. PcpA expression is repressed under high manganese concentrations, similar to those found in secretions. In this study, we have demonstrated that PcpA elicits statistically significant protection in murine models of pneumonia and sepsis. In the model of pneumonia with each of four challenge strains, statistically fewerS. pneumoniaecells were recovered from the lungs of mice immunized with PcpA and alum versus mice immunized with alum only. The immunizations reduced the median CFU by 4- to 400-fold (average of 28-fold). In the model of sepsis using strain TIGR4, PcpA expression resulted in shorter times to become moribund and subcutaneous immunization with PcpA increased survival times of mice infected with wild-type PcpA-expressing pneumococci.

The article considers the reasons for the difficulties of etymologization ancient ethnic and geographical names of the Volga-Oka interfluve. Shows the historical background and general foundations of a number of ethnonyms, ethnotonyms and toponyms (Saami, Merya, Murom, Chud, Lob river, Ruza river, Moskva River, Moscow, Mozhaisk, Kolomna, etc.). The author presents a set of identical names of the Volga-Oka interfluve and places of established settlement of the Saami. The facts and substantiations presented in the article lead to the conclusion about the existence on the territory of the Volga-Oka interfluve before the appearance of the Slavs of regional toponymy based on the Sami and, possibly, the near Finno-Ugric languages.
