Abstract
Copper complexes with 1,3-disubstituted thiourea derivatives, all containing 3-(trifluoromethyl)phenyl tail and 1-alkyl/halogen-phenyl substituent, were synthesized. The experimental spectroscopic studies and theoretical calculation revealed that two ligands coordinate to Cu(II) in a bidentate fashion via thiocarbonyl S and deprotonated N atoms of thiourea moiety. Such monomers are characteristic of alkylphenylthiourea complexes, whereas the formation of a sandwich-type dimer is observed for halogeno derivatives. For the first time, the structural identifications of CuN2S2-based complexes using experimental and theoretical X-ray absorption near edge structure are demonstrated. The dimeric halogeno derivatives showed higher antimicrobial activity in comparison with alkylphenylthiourea complexes. The Cu(II) complex of 1-(4-chloro-3-nitrophenyl)-3-[3-(trifluoromethyl)phenyl]thiourea was active against 19 strains of methicillin-resistant Staphylococci (MIC = 2 µg/mL). This derivative acted as a dual inhibitor of DNA gyrase and topoisomerase IV isolated from Staphylococcus aureus. Additionally, complexes of halogenphenylthiourea strongly inhibited the growth of mycobacteria isolated from tuberculosis patients, even fourfold stronger than the reference isoniazid. The complexes exerted weak to moderate antitumor activity (towards SW480, SW620, and PC3) being non-toxic towards normal HaCaT cells.

Abstract
Pseudomonas aeruginosa is a severe bacterial pathogen. Due to the genetic flexibility among strains, chronic airways infection can lead to mortality among cystic fibrosis (CF) patients. It is essential to develop patient-specific therapy which will rely on phenotypic and genomic diversity. The primary objective of this study was to assess the genomic variability of P. aeruginosa strains, using two different molecular techniques for tracking the epidemiological transmissions. This study applied a multiple-locus variable-number tandem-repeat (VNTR) analysis (MLVA) for an efficient genotyping of clinical P. aeruginosa strains isolated from CF patients and compared results with a TRS-PCR typing. The percentage similarity analysis was performed using the categorical multi-state coefficient and UPGMA method. Based on the MLVA and TRS-PCR group assessment, 43 P. aeruginosa strains/variants were detected among the 63 clinical isolates from eight CF patients. The study of P. aeruginosa isolates has revealed that during chronic bacterial infections, CF patients harbor different P. aeruginosa strains or variants within the same host over the years. P. aeruginosa genotypes diversity may result from infection with several strains and result from a microevolution process of an initially acquired strain. The TRS-PCR method proposed in this work can complement the MLVA scheme. It can also be used as a preliminary method for genetic typing of P. aeruginosa isolates in CF patients.

Abstract
OBJECTIVE Antineutrophil cytoplasmic antibodies (ANCAs) are considered a risk factor for granulomatosis with polyangiitis (GPA) exacerbation, especially when staphylococcal superantigens (SAgs) are present in nasal swabs. Their role in monitoring disease activity remains controversial. This study determined the relationship of ANCAs with disease activity and presence of SAgs in GPA patients. METHODS Among a total of 115 GPA patients hospitalized in the period 2009-2016, we investigated the presence of SAgs and ANCA concentration. Blood samples and nasal swabs were taken at each visit (referred further to as episodes). Disease activity was assessed using the Birmingham Vasculitis Activity Score (BVAS). RESULTS We analyzed 362 episodes. ANCAs were detected in 215 (59.4%), while SAgs were detected in 126 (34.8%) episodes. We found a significant correlation between the presence of ANCAs and disease activity (p = 0.0032), as well as between their level and GPA severity (r = 0.25363, p = 0.000001). We also determined that an ANCA values ≥ 138 Ru/ml were an indicator of active disease with high specificity and low sensitivity (84.4% and 37.3%, respectively). The relationship between ANCA presence and the presence of SAgs was not confirmed; however, when SAgs were analyzed based on the different types, ANCA levels were found to be significantly higher in the group with SAg type B (p = 0.031). CONCLUSIONS There was no detectable evidence for the association between ANCA level and the presence of SAgs. Although monitoring ANCA levels as a marker of disease activity may be clinically relevant, GPA management cannot proceed on the basis of ANCA levels alone. Key Points • ANCA concentration usually correlates with GPA activity, although in half of patients, ANCAs persist despite effective treatment and clinical remission. • ANCA values of 138 Ru/ml seem to be an indicator of active disease with high specificity, but low sensitivity. • Although there is a relevance for ANCA monitoring as a marker of disease activity, GPA management cannot be based on ANCA levels alone. • The suspected clinical correlation between ANCA formation and SAg presence in nasal swabs is not obvious and requires further investigations.

Abstract
OBJECTIVES Nasal carriage of Staphylococcus aureus and its superantigens (SAg) seem to be a risk factor disease exacerbation in granulomatosis with polyangiitis (GPA). We investigated the association between the presence of SAg in nasal swabs and activity of disease in GPA patients also taking into account correlation with an antimicrobial treatment. METHODS In a prospective study of a total of 150 GPA patients hospitalised in the period 2009-2016, nasal swabs were examined for the presence of Staphylococcus aureus and SAg. Subsequently, the association with disease activity was assessed. RESULTS Of 362 Staphylococcus aureus-positive nasal swab cultures from 115 of the 150 patients, the presence of at least one SAg in 126 samples (34.8%) from 56 patients (48.7%) was found. Among the 17 patients with limited to subglottic stenosis (SGS) disease, SAg were detected in 6 cases (35.3%). We did not find a significant correlation between the presence of SAg and disease activity (p=0.986), although when individual SAg were analysed separatively, SED and TSST-1 were more frequently present in active disease. Additionally, the results of the analysis demonstrated a protective effect of trimethoprim/sulfamethoxazole (T/S) treatment (0R 0.52, p<0.0092) in GPA patients. Interestingly, GPA limited to SGS appeared as an unfavourable factor associated with disease activity (0R 1.84, p=0.05). CONCLUSIONS The association between staphylococcal SAg in nasal swabs and GPA activity is not evident. Multiple mechanisms that may lead to disease activation still need to be investigated.

Abstract
Background: On account of emergence of multi- and extensively drug-resistant Mycobacterium tuberculosis (Mtb) strains, combinations of drugs with natural compounds were tested to search for antibiotic activity enhancers. In this work we studied terpenes (α-pinene, bisabolol, β-elemene, (R)-limonene, (S)-limonene, myrcene, sabinene), which are the main constituents of essential oil obtained from Mutellina purpurea L., a plant with described antitubercular activity, to investigate their interactions with antibiotics against reference Mtb strains and multidrug-resistant clinical isolates. Methods: The serial dilution method was used to evaluate the minimal inhibitory concentration (MIC) of tested compounds, while the fractional inhibitory concentration index (FICI) was calculated for characterization of interactions. Moreover, IC50 values of tested compounds were determined using monkey kidney epithelial cell line (GMK). Results: The combinations of all studied terpenes with ethambutol or rifampicin resulted in a synergistic interaction. Bisabolol and (R)-limonene decreased the MIC for rifampicin at least two-fold for all tested strains, however no synergistic action was observed against virulent strains. The tested terpenes showed slight (bisabolol) or no cytotoxic effect against normal eukaryotic cells in vitro. Conclusions: The obtained enhanced activity (FICI < 0.5) of ethambutol and rifampicin against H37Ra strain under the influence of the studied terpenes may be correlated to the capability of essential oil constituents to modify bacterial resistance mechanisms in general. The observed differences in avirulent and virulent bacteria susceptibility to terpenes tested separately and in combinations with antibiotics can be correlated with the differences in the cell wall structure between H37Ra mutant and all virulent strains.

Abstract
A series of new thiourea derivatives of 1,3-thiazole have been synthesized. All obtained compounds were tested in vitro against a number of microorganisms, including Gram-positive cocci, Gram-negative rods and Candida albicans. Compounds were also tested for their in vitro tuberculostatic activity against the Mycobacterium tuberculosis H37Rv strain, as well as two 'wild' strains isolated from tuberculosis patients. Compounds 3 and 9 showed significant inhibition against Gram-positive cocci (standard strains and hospital strain). The range of MIC values is 2-32 µg/mL. Products 3 and 9 effectively inhibited the biofilm formation of both methicillin-resistant and standard strains of S. epidermidis. The halogen atom, especially at the 3rd position of the phenyl group, is significantly important for this antimicrobial activity. Moreover, all obtained compounds resulted in cytotoxicity and antiviral activity on a large set of DNA and RNA viruses, including Human Immunodeficiency Virus type 1 (HIV-1) and other several important human pathogens. Compound 4 showed activity against HIV-1 and Coxsackievirus type B5. Seven compounds resulted in cytotoxicity against MT-4 cells (CC50<10 µM).

Abstract
Background Rifampin is a first line antituberculosis drug active against bacilli in logarithmic and stationary phase, which interferes with RNA synthesis by binding to bacterial RNA polymerase. Tubercle bacilli achieve resistance to rifampin by accumulation of mutations in a short-81 bp region of the rpoB gene. Among many mutations identified in the rpoB gene, few were verified by molecular genetic methods as responsible for resistance to rifampin (RMP). Results In this study eight different mutations identified in an 81 bp section of a "hot spot" region of the rpoB gene of RMP resistant Mycobacterium tuberculosis clinical strains were evaluated in respect to drug resistance. It was found that: mutations in positions 526 (H/D), 516 (D/V) and 531 (S/L) result in high level resistance to rifampin; mutations in positions 516 (D/Y), 515 (M/I), 510 (Q/H) or a double mutation in codons 512 (S/I) and 516 (D/G) relate to low level of resistance. Gene rpoB carrying mutations in codon 513 (Q/L) introduced into an M. tuberculosis laboratory strain did not cause resistance to rifampin, however the same gene introduced into two different clinical strains did, with the level of resistance depending on the host strain. Conclusion Mutations in an 81 bp "hot spot" region of the rpoB of M. tuberculosis lead to different levels of resistance to rifampin. Some mutations in this "hot spot" region of rpoB require a specific genetic background for the host strain to develop resistance to rifampin. Therefore, the identification of such mutations in a clinical M. tuberculosis strain is not enough to classify the given strain as resistant to rifampin.

Abstract
Resistance of Mycobacterium tuberculosis to pyrazinamide (PZA) derives mainly from mutations in the pncA gene. We developed a reverse hybridization-based line probe assay with oligonucleotide probes designed to detect mutations in pncA. The detection of PZA resistance was evaluated in 258 clinical isolates of M. tuberculosis. The sensitivity and specificity of PZA resistance obtained by this new assay were both 100%, consistent with the results of conventional PZA susceptibility testing. This assay can be used with sputa from tuberculosis patients. It appears to be reliable and widely applicable and, given its simplicity and rapid performance, will be a valuable tool for diagnostic use.

Abstract
A total of 105 rifampin (RMP)- and/or isoniazid (INH)-resistant strains of Mycobacterium tuberculosis isolated from different parts of Poland in 2000 were screened for mutations associated with resistance to these drugs by two molecular methods, namely sequence analysis and real-time PCR technology. Three loci associated with drug resistance were selected for characterization: they were rpoB (RMP), katG, and the regulatory region of inhA (INH). Nineteen different mutations were identified in 64 RMP-resistant strains, and five new alleles were described. The most common point mutations were in codons 531 (41%), 516 (16%), and 526 (9%) of the rpoB gene. Mutations were not found in two (3%) of the isolates. In the case of resistance to INH, six different mutations in the katG gene of 83 resistant strains were detected. Fifty-seven (69%) isolates exhibited nucleotide substitutions at codon 315. One strain harbored a mutation affecting codon 279 (Gly279Thr). Twelve of 26 INH-resistant strains with the wild-type codon 315 (14.5% of all strains tested) had the mutation -15C-->T in the regulatory region of inhA. A full correlation between the DNA sequence analysis and real-time PCR data was obtained. We conclude that the real-time PCR method is fast and reliable for the detection of RMP and INH resistance-associated mutations in M. tuberculosis clinical isolates.

Abstract
SETTING Three years after the last survey of drug-resistant tuberculosis in Poland, a nationwide survey was conducted by the National Tuberculosis Reference Laboratory in cooperation with all TB laboratories. OBJECTIVE To determine the prevalence and patterns of primary and acquired drug resistance among Mycobacterium tuberculosis isolates recovered from tuberculosis patients in Poland in 2000 and to compare the results with an earlier survey carried out in 1997. DESIGN In a prospective survey based on the questionnaires and strains of M. tuberculosis from all 16 regional centres participating in the study, 3705 questionnaires and cultures were obtained from 3037 new and 668 previously treated patients excreting TB bacilli during the 12-month period of 2000. Tests of resistance to isoniazid, rifampicin, streptomycin and ethambutol were performed using Löwenstein-Jensen and the Bactec system. RESULTS AND CONCLUSION Compared with the previous survey in 1997, the current survey showed a twofold increase in tuberculosis resistance in new cases: any resistance was 3.6% in 1997 vs. 6.1% in 2000 (P < 0.001), multidrug resistance was 0.6% vs. 1.2% (P < 0.01), and no cases of four-drug resistance in 1997 vs. 15 cases in 2000. No statistical differences were observed in the rate of acquired resistance in both surveys.

Abstract
OBJECTIVE To determine the prevalence and patterns of primary and acquired drug resistance among Mycobacterium tuberculosis isolates recovered from tuberculosis patients in Poland. DESIGN In a prospective survey, M. tuberculosis strains were collected from 3970 tuberculosis patients (2976 newly diagnosed cases and 994 previously treated patients) bacteriologically confirmed by culture between November 1996 and October 1997. METHODS Drug susceptibility testing to isoniazid (INH), streptomycin, ethambutol and rifampicin (RMP) was performed on Löwenstein-Jensen medium according to the proportion method and/or using the radiometric Bactec 460 TB system. RESULTS AND CONCLUSION The male to female ratio was 2.61:1. The patients were aged between 6 and 82 years, with 86% of males and 77% of females aged over 35 years. Primary resistance to any drug was found in 3.6% of new patients; any INH resistance was 2.6%, any RMP resistance was 0.7%, and multidrug resistance (to INH and RMP [MDR]) was 0.6%. In previously treated cases, resistance to any drug was 17.0%, any INH resistance 14.1%, any RMP resistance 7.8%, and MDR 7.0%. Drug-resistant tuberculosis does not present a big problem in Poland; primary drug resistance has been monitored since 1960 with decreasing frequency, and rates remain at the same level as 20 years ago. Studies such as this should be conducted regularly to monitor drug resistance in Poland in order to effectively manage national tuberculosis control efforts.

Abstract
SETTING The absorption of rifampicin, isoniazid and pyrazinamide was tested after administration of each drug in free combinations and in a fixed-dose combination of the three drugs, known as Trifazid. OBJECTIVE To examine the relative bioavailability of rifampicin, isoniazid and pyrazinamide after oral administration of the drugs given alone in comparison to that of the same drugs after administration of Trifazid. DESIGN An open, randomized, cross-over study comprising 16 healthy volunteers. RESULTS The pattern of absorption, plasma concentrations and pharmacokinetic parameters were very similar after administration of the drugs in free and fixed combinations. CONCLUSION The triple combination of antituberculosis drugs could replace the separate drugs in the treatment of tuberculosis.
