    Vaccine protection against photogenic gram-positive bacteria including different species ofstreptococci is an important problem of contemporary molecular biology. Streptococcal infections are mostcommon bacterial infections surpassing by the economic losses all the infections excluding influenza. The gatesof streptococcal infection, oral cavity or vagina, are covered with immune and non-immune mucosal cells thatare the first line of defenses. Subcutaneous immunization not always stimulate the local immunity on mucosalsurfaces. On the other hand, mucosal vaccination can provide an appropriate local immune response togetherwith systemic protection. However, mucosal immunization often requires usage of special and effectiveadjuvants especially in case of vaccines based on recombinant proteins.For protection against Streptococcus pneumoniae infection, two chimeric recombinant proteins (PSPF andPSP) have been tested as vaccines. Recombinant proteins PSPF and PSP carry immunogenic epitopes fromthe respiratory pathogen including PspA, Spr1875 and PsaA. PSPF structure also carries a fraction of flagellin-FliC molecule in comparison with PSP, which does not have this fragment. This portion of PSPF was includedas internal adjuvant intended for the stimulation of Toll-like receptor 5.In this work, the adjuvant capacity of two probiotic strains, Lactobacillus rhamnosus CRL1505 andL. rhamnosus L32 was evaluated. It was demonstrated that both lactic acid bacteria strains were able to provideadjuvant effects by enhancing the mucosal and systemic immune responses after their co-administration withthe recombinant chimeric protein PSPF. The adjuvant effect of both Lactobacillus strains was significantlydecreased after their thermal inactivation. However, the cell walls of bacteria showed a marked adjuvant activity.An improved protection against several S. pneumoniae serotypes after mucosal immunization of infant micewith PSPF vaccine with probiotic strains or their cell walls was also demonstrated here.The recombinant chimeric protein PSPF administered with immunomodulatory probiotic strains or theirbacterial components would be a promising vaccine for immunization of humans against S. pneumoniae,particularly in children.Одной ΠΈΠ· Π½Π°ΠΈΠ±ΠΎΠ»Π΅Π΅ Π°ΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½Ρ‹Ρ… Π·Π°Π΄Π°Ρ‡ ΠΌΠ΅Π΄ΠΈΠΊΠΎ-биологичСской Π½Π°ΡƒΠΊΠΈ являСтся созданиС Π²Π°ΠΊΡ†ΠΈΠ½Π½Ρ‹Ρ… ΠΏΡ€Π΅ΠΏΠ°Ρ€Π°Ρ‚ΠΎΠ² ΠΏΡ€ΠΎΡ‚ΠΈΠ² ΠΏΠ°Ρ‚ΠΎΠ³Π΅Π½Π½Ρ‹Ρ… стрСптококков – самых распространСнных Π±Π°ΠΊΡ‚Π΅Ρ€ΠΈΠ°Π»ΡŒ-Π½Ρ‹Ρ… Π²ΠΎΠ·Π±ΡƒΠ΄ΠΈΡ‚Π΅Π»Π΅ΠΉ Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π½ΠΈΠΉ Ρ‡Π΅Π»ΠΎΠ²Π΅ΠΊΠ°, экономичСский ΡƒΡ‰Π΅Ρ€Π± ΠΎΡ‚ ΠΊΠΎΡ‚ΠΎΡ€Ρ‹Ρ… уступаСт лишь потСрям ΠΎΡ‚ Π³Ρ€ΠΈΠΏΠΏΠΎΠ·Π½ΠΎΠΉ ΠΈΠ½Ρ„Π΅ΠΊΡ†ΠΈΠΈ.

    Abstract. Design of an effective and safe vaccine against pathogenic streptococci is still on the agenda, in spite of numerous attempts in this area undertaken by different laboratories. In order to improve immunogenicity of recombinant vaccine preparations, a selection of effective adjuvants is necessary. Previously, two recombinant GBS polypeptides P6 and ScaAB were found to be immunogenic, and their injection in separate preparations or mixed manner boosted production of specific and protective antibodies with high affinity. Four different adjuvants (Freund adjuvant, aluminum hydroxide, Bestim and Interleukine-1Ξ²) have been tested for immunization of mice with single polypeptides, or with their mixtures. As a result of vaccination, it was demonstrated that aluminum hydroxide was providing the most desirable immunological parameters of immune response among the adjuvants tested. A mixture of polypeptides containing aluminum hydroxide was found to produce specific antibodies with better opsonizing activity against group B streptococci. (Med. Immunol., 2008, vol. 10, N 2-3, pp 215-222)
