[Substantion of the reference Values of SCFA in saliva in ratients without upper respiratory tract diseases.].

Biochemical indicators of saliva were studied in 47 patients of the intensive care unit and intensive care unit of a neurosurgical hospital with varying degrees of severity of the disease. The method of gas-liquid chromatography of the acidified substrate of the saliva filtrate determined the concentrations of short-chain fatty acids (SCFA) and their reference values for patients without respiratory tract diseases. The threshold values of the concentrations of SCFA and the values of their calculated indices were determined by ROC analysis with the construction of the ROC curve, calculation of the area under the curve (AUC) and the cutoff threshold CutOff.

[Efficacy of laboratory methods of diagnostic of purulent bacterial meningitis.].

According to the World Health Organization, every year about 1 million cases of purulent bacterial meningitis (PBM) are registered in the world, of which 200 thousand cases end in death. Bacterial meningitis is polyethiologic, which makes the task of determining the pathogen the main in the organization of epidemiological surveillance, treatment regimens, planning of preventive and anti-epidemic measures. The quality of laboratory diagnostics has a key influence on this.

[Comparative analysis of informative-diagnostic properties of mucosa immune-reactivity parameters].

Aim: Study the features of immune-reactivity expression in mucosa depending on their topicity and etiopathogenesis of the pathological process.

Materials And Methods: Data from 30 clinically healthy children and 77 children with acute and recurrent diseases of respiratory tract: 51--with acute and 15--with chronic bronchitis; as well as 132 women: 41--with active stage of acute urogenital chlamydia infection, 29--with recurrent chronic process, 30--with non-recurrent form and 32 clinically healthy women were analyzed. Saline and urogenital tract mucosa discharge was analyzed for IgG, sIgA and secretory component, IL-1beta, 4, 6, 8, 9, 10, 12, IFNgamma, TNFalpha and GM-CSF, TLR-2, TLR-3, TLR-4, TLR-8 gene expression levels as well as content of lysozyme, total protein and leucocytes.

[The phylogenetic position of Chlamydia strains isolated from monkeys and humans with Chlamydial pathology in the family Chiamydiaceae. Genotypic and phenotypic properties of this pathogen].

Based on the results of the comparative analysis concerning relatedness and evolutional difference of the 16S - 23S nucleotide sequences of the middle ribosomal cluster and 23S rRNA I domain, and based on identification of phylogenetic position for Chlamydophila pneumoniae and Chlamydia trichomatis strains released from monkeys, relatedness of the above stated isolates with similar strains released from humans and with strains having nucleotide sequences presented in the GenBank electronic database has been detected for the first time ever. Position of these isolates in the Chlamydiaceae family phylogenetic tree has been identified. The evolutional position of the investigated original Chlamydia and Chlamydophila strains close to analogous strains from the GenBank electronic database has been demonstrated.
