S.1, Kosikowska U.1, Chwiejczak E.2, Malm A.1 1Department of Pharmaceutical Microbiology with Laboratory for Microbiological Diagnostics, Medical University of Lublin, Chodzki Str. 1, 20-093 Lublin, Poland; 2Students Scientific Association at the Department of Pharmaceutical Microbiology with Laboratory for Microbiological Diagnostics, Medical University of Lublin, Poland Introduction. Bacteria have many different mechanisms of iron uptake including small molecules called siderophores secreted outside the cells and chelating iron from surrounding or specific proteins ExbBD and TonB on outer membrane and playing a role as a receptors binding an iron from e.g.: hemoglobin, haptoglobin, transferrin or lactoferrin. In Gram-negative microorganisms iron is transported through outer membrane and then via the periplasm and the inner membrane, what requires an energy flow. TonB protein, being an energy-transducing protein for iron uptake, is a distinct part of a complex composed of three proteins ExbB-ExbD-TonB. TonB protein is placed in the inner membrane and extends along the periplasm. Other proteins are located only in the inner membrane. Due to the presence of TonB protein both membranes (outer and inner) are connected together and allow the energy flow required to iron transport [1,2,4,5]. H. influenzae is a part of human respiratory microbiota and also an important pathogen especially for younger children. It is believed that the ability to growth and pathogenicity of H. influenzae is generally associated with the requirement for iron from external sources. Literature data indicated that in H. influenzae as well as in E. coli an uptake and transport of iron is strongly dependent on the TonB protein [2,3,5]. Furthermore, inactivation of tonB gene in H. influenzae serotype b (Hib) caused a lack of capability to iron uptake, transport and use of this element for life processes, including an ability to involve infections. In consequence, bacteria became avirulent [5]. The aim of the study. The aim of this study was to analyze the prevalence of tonB gene in nasopharyngeal H. influenzae isolates collected from children with recurrent respiratory tract infections who underwent adenoidectomy. Additionally, a molecular typing on the basis of a restriction endonuclease digestion of the tonB- positive strains was performed and a structural similarity of DNA patterns was assessed. Methods of research. The study included 37 isolates of H. influenzae selected from children aged 2-5 years old with recurrent respiratory tract infections who underwent adenoidectomy, as previously described [3]. The isolates were obtained from nasopharyngeal swabs. Additionally, the reference strain of Haemophilus influenzae ATCC 10211 from the American Type Culture Collection (ATCC) was used. Identification of haemophili were performed using the API NH microtest 3 (BioMérieux, France). The tonB gene (~813 bp) was identified in a classic PCR reaction using a specific Ton1 (5’-GCAAGCACAACAAGTGCAGCTAA-3’) and Ton2 (5’-GCCGCCTTATCTAAACTTTCATCG-3’) primers [4]. PCR amplification 25 µL reaction mixture included: REDTag® Ready Mix™ PCR Reaction Mix (Sigma Aldrich, Germany), 20 µM of each primer, 1 µL of genomic DNA and nuclease-free water (Sigma Aldrich, USA). Amplification was performed using the T20 Personal thermocycler (Biometra, Germany) and carried out for 34 cycles consisting of: denaturation at 94°C for 1 min, annealing for 1 min at 48°C and primer extension at 72°C for 1 min. Products were detected by electrophoresis on a 1.5% agarose gels (Sigma Aldrich, Germany) with ethidium bromide (1 mg/mL) in 0.5x Tris-borate-EDTA buffer at 120 V for 1.5 h. Gels were observed under UV light, photographed and documented using the Quantum Vilber-Gel-documentation tool (Vilber Lourmat, Germany). All DNA probes with detected tonB gene were treated with the two FastDigest enzymes XhoI and BglII (ThermoFisher Scientific, USA). A restriction analysis was performed according to Matar et al. [4] and 30 µL reaction mixture was prepared in accordance with enzymes manufacturer’s instructions. The obtained restricted fragments were separated by electrophoresis on 2% agarose gels at 120 V for 2 h. As described above, gels were observed under UV light, photographed and documented using abovementioned documentation system (Figure 1).

XhoI and BglII restriction endonuclease digestion results of PCR products of tonB gene (~813 bp) in nasopharyngeal Haemophilus influenzae strains isolated from children with recurrent respiratory infections who underwent adenoidectomy. 4 Main results. According to our results, among 37 nasopharyngeal H. influenzae isolates from children with recurrent respiratory infections who underwent adenoidectomy the occurrence of tonB gene as revealed by PCR product ~813 bp was observed in 33/37 (89%) of isolates. Analysis of restriction enzyme digestion of DNA fragments with detected tonB gene in H. influenzae strains are summarized in Table 1. A digestion with the endonuclease XhoI showed that PCR products obtained from 32/37 (86%) of strains and the reference strain H. influenzae ATCC 10211 were cut by this enzyme into two fragments of ~204 and ~609 bp. In case of a reaction with the BglII enzyme, PCR products from 15/37 (41%) strains were cut into two fragments of ~388 and ~425 bp. On the basis of the results of PCR products digestion involving XhoI and BglII endonucleases, a four possible restriction patterns were defined: I (X+B+) – PCR products cut by both XhoI and BglII, II (X+B-) – PCR products digested only with XhoI, III (X-B-) – uncut PCR products and IV (X-B+) – PCR products digested only with BglII. The obtained results showed that most isolates were characterized by the II restriction pattern – 18/37 (49%), followed by the I pattern with 14/37 (38%) representatives. Conclusions. The high prevalence of tonB gene among nasopharyngeal H. influenzae isolates in children with recurrent respiratory infections who underwent adenoidectomy suggests its importance not only as a virulence factor responsible for pathogenicity and invasive infections but also for facilitating bacteria survival in a human body and colonization by them of e.g. nasopharynx.

Department of Pharmaceutical Microbiology with Diagnostic Microbiology Unit, Medical University, Lublin, Poland Introduction. The yeasts belonging to Candida spp., including C. albicans and other species, known as non-albicans Candida spp., are commensal organisms that can be isolated from the oral cavity, upper respiratory tract as well as from vagina in healthy people. These yeasts are classified also as opportunistic pathogens, which can cause candidiasis – endogenous infections from superficial to seriously deep-seated mycoses under predisposing conditions [1,2]. However, following the widespread and increased use of immunosuppressive therapy together with broad-spectrum antimycotic therapy, the frequency of mucosal and systemic infections caused by C. glabrata has increased significantly [1,2,3]. This yeast is often the second or third most common cause of candidiasis after C. albicans. Infections caused by C. glabrata are difficult to treat and are often resistant to many azole antifungal agents, especially fluconazole [2,3]. Currently, there are few recognized virulence factor of C. glabrata. One of them is the biofilm formation. These yeasts can develop form this structure on several surfaces such as oral, urinary and vaginal epithelia or central venous catheters, dental prostheses and other indwelling devices. The biofilms are extremely resistant to antifungal drugs and are a source of reinfections [2]. Biofilm formation by yeasts is complex process regulate by several genes. Among them, EPA6 and AWP2 encodes an adhesins or cell wall proteins of C. glabrata. In turn, ACT1 gene is responsible for encoding the structural protein actin or YAK1 encodes a protein kinase [1]. The aim of the study. The aim of the study was to estimate the prevalence of the selected genes responsible for biofilm formation: ACT1, AWP2, EPA6 and YAK1 in C. glabrata strains isolated from the oral cavity in patients with immune disorders. Methods of research. Totally, 50 strains of C. glabrata isolated from patients with immunosuppression, e.g. with cancer, chronic hepatitis C, diabetes mellitus and elderly people aged of 65 years old or older were included in the study. The Ethical Committee of the Medical University of Lublin approved the study protocol (No. KE- 0254/75/2011). Moreover, the reference strain of C. glabrata ATTC 90030 belonging to the American Type Culture Collection was used as a control microorganisms. To assess the incidence of the genes involved in biofilm formation by C. glabrata, the isolates were grown overnight in Sabouraud Dextrose bulion (SDB) medium. The DNA from the strains was prepared using Genomic Mini AX YEAST (SPIN) (A&A Biotechnology, Poland), according to the manufacturer’s procedure. PCR method was performed with ACT1, AWP2, EPA6 and YAK1 primers (Genomed S.A. Poland) (see Tab. 1). PCR reactions were carried out in the thermocycler and amplification conditions were as following: initial denaturation at 95 ºC for 5 min and 48 cycles of 7 denaturation at 95 ºC for 10 s, followed by primer annealing at 56 ºC for 30 s and elongation at 72 ºC for 30 s. Final extended elongation at 72 ºC have lasted 5 min. The polymerase chain reaction was performed in 0.5 ml microcentrifuge tubes in a 15-µl final reaction mixture containing 50-200 ng of C. glabrata DNA as template, 7.5 µl of REDtag Ready MixTM PCR Mix (Sigma-Aldrich, USA), 5.9 µl of distilled water and 0.3 µl of each 20 µM primer. For each experiment, the size of DNA fragments amplified by PCR were determined by direct comparison with the DNA marker – 100 bp Ladder Plus (Fermentas, Lithuania). Control samples without template DNA were included in each run and reproducibility was checked for each reaction. The PCR products were separated using electrophoresis in agarose gels (1.5%) at 120 mV for approximately 60 min at room temperature in TBE buffer (Tris Borate Electrophoretic Buffer, 89 mMTris/HCl, 89 mM boric acid, 2.5 mM EDTA, 0.01% ethidium bromide pH 8.0) (Sigma-Aldrich, USA). Reaction products were detected and visualized with UV light. Table 1. Primers used for detection by PCR of the selected genes responsible for biofilm formation in C. glabrata.

Explanations: I – the presence of all studied genes: ACT1, AWP2, EPA6, YAK1; II – ACT1, AWP2, EPA6; III – AWP2, EPA6; IV – EPA6, YAK1; V – ACT1, AWP2, YAK1; VI – AWP2, YAK1; VII – YAK1. 8 Main results. Using the PCR reaction, products of the studied genes involved in biofilm formation in C. glabrata were detected with the prevalence depending on the strain. Seven gene combinations were defined. Type I, which included all of the tested genes was found in the majority – 76 % of isolates. Other types were detected to occur with lower frequency (2 – 8 %) (see Fig. 1). In the case of the C. glabrata ATTC 90030, the presence of type I was found. The most frequently detected genes, were AWP2 and EPA6, which occurred with similar incidence – 94 % isolates. The remaining genes, namely ACT1 and YAK1, were found also to occur with high frequency – 86 %. Conclusions. The high prevalence of genes involved in biofilm formation in C. glabrata isolated from the oral cavity in immunocompromised patients suggests that these genes may be regarded as an important factor responsible for colonization of human body by C. glabrata as well as its pathogenicity.

Rheumatoid arthritis is the serious autoimmune disease. It is caused by high rates disability and mortality of patients, reducing their quality of life and significant financial costs for treatment [2,3]. Conducting rational pharmacotherapy of the disease and optimization of its costs are relevant and determine the conduct of the clinical and economic evaluation of rheumatoid arthritis pharmacotherapy. The purpose of this study is to evaluate the structure of medicinal preparations costs for the treatment of patients with rheumatoid arthritis in one of health care institutions in Kharkov. Methods of research. Supplementary clinical and economic method: ABC- analysis [1]. Research lasted for 2015. The main results. According to the 84 disease histories of patients with rheumatoid arthritis aged from 39 to 62 years (30 men and 54 women) 37 trade names (TN) of medicines (20 international non-patent names (INN)) from 13 pharmacological groups have been determined. Correlation of Ukrainian and foreign drugs is 1:2.7. The division TN of medications into the ABC-groups was the following, group A – 9 medications with 79.46 % of costs from the total costs sum on all researched medications; group B – 11 medications (15.16 % of costs), group C – 17 medications (5.38 % of costs). The leader of ABC-rating according to TN became a immunosuppressant “Methotrexate” (“Ebewe Pharma”, tabl. 2.5 mg № 50) which is 22.92 % of total sum costs. The most expensive pharmacological groups – immunosuppressants (38.74 % of costs, 2 INN, 2 TN) and nonsteroidal anti-inflammatory drugs (24.51% of costs, 2 INN, 6 TN). Conclusion. The results of this carried out ABC-analysis can be the basis to improve the pharmacotherapy of rheumatoid arthritis in the mentioned health care institution. References 1.
