Abstract
The changing of microbiome could precede the development of coeliac disease (CeD). We compared the bacterial profile of microbiota of tissues collected simultaneously from the stomach and duodenum in newly diagnosed patients with CeD. Biopsies were collected from 60 children and adolescents aged 2-18 years: (1) 40 patients with CeD; (2) 20 children as control group. The evaluation of the bacterial microbiota was carried out by sequencing the V3-V4 regions of the 16S rRNA subunit, using next-generation sequencing (NGS). The composition of bacterial microbiota was correlated with clinical and blood parameters. The beta diversity analysis revealed a significant dissimilarity in the gastric samples between the CeD and control group (Bray-Curtis index, P = 0.008, and weighted UniFrac distance, P = 0.024). At L2 (phylum level), Campylobacterota was only present in the stomach of the CeD group. A comparison of the abundance of bacteria between the stomach and duodenum showed significant differences in 10 OTUs (operational taxonomic units) in the control and 9 OTUs in the CeD group at L6 (genus) and in 8 OTUs and in 6 OTUs, respectively, at L7 (species). A significant correlation was observed between the genus Novosphingobium in stomach of CeD group and possession of the DQ2.5 and DQ 8 allele, and in the duodenum - between the DQ 8 allele and the species Blautia wexlerae. Significant differences in selected, little-known genera of bacteria suggest their potential role as new biomarkers in the development of CeD. To fully understand the mechanism of CeD development in genetically predisposed individuals, it is necessary to take into account not only the abundance of a given genus or species of bacteria, but also the anatomical location of its occurrence.

Abstract
BACKGROUND & AIMS Butyric (one of the short-chain fatty acids), a major byproduct of the fermentation of non-digestible carbohydrates (e.g. fiber), is supposed to have anti-obesity and anti-inflammatory properties. However, butyrate's potential and mechanism in preventing obesity and the efficient form of administration remain to be clarified. METHODS Hence, we studied the effect of oral supplementation with 5% (w/w) sodium butyrate and 4% (w/w) β-glucan (fiber) on young male mice (C57BL/6J) with high-fat diet-induced obesity (HFD: 60 kcal% of fat + 1% of cholesterol). Six weeks old mice were fed diets based on HFD or control (AIN-93G) diet with/without supplements for 4 weeks. The unique, interdisciplinary approach combining several Raman-based techniques (including Raman microscopy and fiber optic Raman spectroscopy) and next-generation sequencing was used to ex vivo analyze various depots of the adipose tissue (white, brown, perivascular) and gut microbiome, respectively. RESULTS The findings demonstrate that sodium butyrate more effectively prevent the pathological increase in body weight caused by elevated saturated fatty acids influx linked to a HFD in comparison to β-glucan, thereby entirely inhibiting diet-induced obesity. Moreover, butyrate significantly affects the white adipose tissue (WAT) reducing the epididymal WAT mass in comparison to HFD without supplements, and decreasing lipid saturation in the epididymal WAT and perivascular adipose tissue of the thoracic aorta. Contrarily, β-glucan significantly changes the composition and diversity of the gut microbiome, reversing the HFD effect, but shows no effect on the epididymal WAT mass and therefore the weight gain inhibition is not as effective as with sodium butyrate. CONCLUSIONS Here, oral supplementation with sodium butyrate and β-glucan (fiber) has been proven to have an anti-obesity effect through two different targets. Administration-dependent effects that butyrate imposes on the adipose tissue (oral administration) and microbiome (fiber-derived) make it a promising candidate for the personalized treatment of obesity.

Abstract
Intestinal dysbiosis can lead to the induction of systemic immune-mediated inflammatory diseases, such as Crohn's disease Although archaea are part of the commensal microbiota, they are still one of the least studied microorganisms. The aim of our study was the standardization of the optimal conditions and primers for sequencing of the gut archaeome using Next Generation Sequencing, and evaluation of the differences between the composition of archaea in patients and healthy volunteers, as well as analysis of the changes that occur in the archaeome of patients depending on disease activity. Newly diagnosed patients were characterized by similar archeal profiles at every taxonomic level as in healthy individuals (the dominance of Methanobacteria at the class level, and Methanobrevibacter at the genus level). In turn, in patients previously diagnosed with Crohn's disease (both in active and remission phase), an increased prevalence of Thermoplasmata, Thermoprotei, Halobacteria (at the class level), and Halococcus, Methanospaera or Picrophilus (at the genus level) were observed. Furthermore, we have found a significant correlation between the patient's parameters and the individual class or species of Archaea. Our study confirms changes in archaeal composition in pediatric patients with Crohn's disease, however, only in long-standing disease. At the beginning of the disease, the archeal profile is similar to that of healthy people. However, in the chronic form of the disease, significant differences in the composition of archaeome begin to appear. It seems that some archaea may be a good indicator of the chronicity and activity of Crohn's disease.

Abstract
INTRODUCTION The effects of SARS‑CoV‑2 infection on the composition of the upper respiratory tract (URT) microbiota are yet to be established, and more attention to this topic is needed. OBJECTIVES The study aimed to assess the bacterial profile and the possible association between the URT microbiota composition and the SARS‑CoV‑2 viral load. PATIENTS AND METHODS Nasopharyngeal swabs were taken from 60 adult patients with SARS‑CoV‑2 infection who were divided into 3 groups based on the quantification cycle (Cq) value in the quantitative polymerase chain reaction test: group I (n = 20), Cq lower than or equal to 31 (high replication rate); group II (n = 20), Cq greater than 31 and lower than 38 (low replication rate), and group III (n = 20), Cq higher than or equal to 38 (virus eliminated from the nasopharyngeal epithelial cells). The obtained genetic libraries of 16S rRNA were sequenced and taxonomic diversity profiling was performed to determine the α- and β‑biodiversity in each group. RESULTS A significantly lower abundance of Prevotella species was noted in group I, as compared with groups II and III. Akkermansia muciniphila, Faecalibacterium prausnitzii, Fusicatenibacterium saccharivorans, and Bacteroides dorei abundance was characteristic of and significantly greater in group I than in groups II and III. Overall, the microbiota composition was the most diverse in group I, whereas groups II and III were more homogenous in terms of taxonomic diversity. CONCLUSIONS The arbitrary division of patients according to the SARS‑CoV‑2 viral load was reflected in diverse composition of their bacterial microbiota, which implies an association between these 2 factors. The patients with a low viral replication rate and those who eliminated the virus from the epithelial cells belonged to a group with a less diverse microbiota community than the patients with a high viral replication rate.

Abstract
BACKGROUND Bariatric surgery is the most effective method of morbid obesity treatment. Microbiota has many functions in human body and many of them remain to be unknown. The aim of this study was to establish if the composition of duodenal microbiota influences success rate of bariatric surgery. METHODS It was a prospective cohort study. The data concerning demographics and comorbidities was collected perioperatively. The duodenal biopsies were collected prior to surgery with the gastroscope. Then DNA analysis was conducted. The data connected to the operation outcomes was gathered after 6 and 12 months after surgery. RESULTS Overall, 32 patients were included and divided into two groups (successful - group 1 and unsuccessful - group 0) based on percentage excess weight loss after 6 months were created. The Total Actual Abundance was higher in group 0. In group 0 there was a significantly higher amount of Roseburia and Arthrobacter (p = 0.024, p = 0.027, respectively). Genus LDA effect size analysis showed Prevotella, Megasphaera and Pseudorhodobacter in group 1 to be significant. Whereas abundance of Roseburia and Arthrobacter were significant in group 0. CONCLUSIONS Duodenal microbiota composition may be a prognostic factor for the success of the bariatric surgery but further research on the larger group is needed.

Abstract
BACKGROUND Numerous studies have shown that in Crohn’s disease (CD), the gut microbiota is of great importance in the induction and maintenance of inflammation in the gastrointestinal tract. Until recently, studies have focused almost exclusively on bacteria in the gut. Lately, more attention has been paid to the role of intestinal fungi.
AIM To study the gut mycobiome analysis of pediatric patients with CD (in different stages of disease activity) compared to healthy children.
METHODS Fecal samples were collected from patients: With active, newly diagnosed CD (n = 50); active but previously diagnosed and treated CD (n = 16); non-active CD and who were in clinical remission (n = 39) and from healthy volunteers (n = 40). Fungal DNA was isolated from the samples. Next, next generation sequencing (MiSeq, Illumina) was performed. The composition of mycobiota was correlated with clinical and blood parameters.
RESULTS Candida spp. were overrepresented in CD patients, while in the control group, the most abundant genus was Saccharomyces. In CD patients, the percentage of Malassezia was almost twice that of the control (P < 0.05). In active CD patients, we documented a higher abundance of Debaryomyces hansenii (D. hansenii) compared to the non-active CD and control (P < 0.05) groups. Moreover, statistically significant changes in the abundance of Mycosphaerella, Rhodotorula, and Microidium were observed. The analyses at the species level and linear discriminant analysis showed that in each group it was possible to distinguish a specific species characteristic of a given patient population. Moreover, we have documented statistically significant correlations between: D. hansenii and patient age (negative); C. zeylanoides and patient age (positive); C. dubliniensis and calprotectin (positive); C. sake and calprotectin (positive); and C. tropicalis and pediatric CD activity index (PCDAI) (positive).
CONCLUSION Mycobiome changes in CD patients, and the positive correlation of some species with calprotectin or PCDAI, give strong evidence that fungi may be of key importance in the development of CD.

Abstract
Abstract Amplicon-based next-generation sequencing (NGS) of the 16S ribosomal RNA (16S) regions is a culture-free method used to identify and analyze Procaryota occurring within a given sample. The prokaryotic 16S rRNA gene contains conserved regions and nine variable regions (V1-V9) frequently used for phylogenetic classification of genus or species in diverse microbial populations. This work compares the accuracy and efficacy of two platforms, iSeq and MiSeq from Illumina, used in sequencing 16S rRNA. The most important similarities and differences of 16S microbiome sequencing in 20 fecal rat samples were described. Genetic libraries were prepared according to 16S Metagenomic Sequencing Library Preparation (Illumina) for the V3 and V4 regions of the 16S. The species richness obtained using iSeq technology was lower compared to MiSeq. At the second taxonomy level (L2), the abundance of taxa was comparable for both platforms. At the L7, the taxa abundance was significantly different, and the number of taxa was higher for the MiSeq. The alpha diversity was lower for iSeq than for MiSeq, starting from the order to the species level. The beta diversity estimation revealed statistically significant differences in microbiota diversity starting from the class level to the species level in samples sequenced on two investigated platforms. This work disclosed that the iSeq platform could be used to evaluate the bacterial profile of the samples to characterize the overall profile. The MiSeq System seems to be better for a detailed analysis of the differences in the microbiota composition. Key points • iSeq platform allows to shorten the sequencing time three times compared to the MiSeq. • iSeq can only be used for an initial and quick microbiome assessment. • MiSeq is better for a detailed analysis of the differences in the microbiota composition.

Abstract
Celiac disease (CD) may cause numerous nutrient deficiencies that a proper gluten-free diet (GFD) should compensate for. The study group consists of 40 children, aged 8.43 years (SD 3.5), on average, in whom CD was diagnosed on the basis of clinical symptoms, immunological and histopathological results. The patients' height, weight, diet and biochemical tests were assessed three times: before diagnosis, after six months, and following one year of GFD. After one year, the patients' weight and height increased but nutritional status (body mass index, BMI percentile) did not change significantly. The children's diet before diagnosis was similar to that of the general Polish population: insufficient implementation of the dietary norm for energy, fiber, calcium, iodine, iron as well as folic acid, vitamins D, K, and E was observed. Over the year, the GFD of the children with CD did not change significantly for most of the above nutrients, or the changes were not significant for the overall assessment of the diet. Celiac patients following GFD may have a higher risk of iron, calcium and folate deficiencies. These results confirm the need for personalized nutritional education aimed at excluding gluten from the diet, as well as balancing the diet properly, in patients with CD.

Abstract
Scabies is the skin infestation caused by Sarcoptes scabiei var hominis. It is one of the commonest dermatological infection which can affect people around the world. However, nails are relatively rarely involved, and the fingernails are mostly infected. The report a case of a 77-year-old woman, long-term pensioner of a nursing home, who had isolated toe subungual Sarcoptes infestation. In addition, the results of systematic review of toenails scabies was presented. Analysis of 21 subungual Sarcoptes infestation cases, revealed that patients in any age (median age 45+/-31.7-year-old) and sex can be affected. Most of the patients had concomitant diseases. Seventy-five percent of cases of nail involvement were treated with combined or sequential therapy. The most used drugs were ivermectin (IVR) and permethrin (PER) (each used in 47.6% cases), following γ-BHC (38.1%) and crotamiton (CRO) (23.8%). It seems that the crucial for adequate diagnosis in scabies affected nails is a precise anamnesis, early and accurate diagnosis that consists of examining not only skin lesions, but including assessing toenails, and differentiation of Sarcoptes infestation from other nail diseases as onychomycosis or psoriasis. Important to achieving a cure is at least frequent nail trimming, softening the nail plate with urea or in the difficult cases the mechanical removal of subungual plaque with using of a scabicide in the location allowing to penatrate it under the nail plate.

Abstract
PURPOSE The aim of this study was to determine quantitative changes in selected species of bacteria (Bacteroides fragilis, Lactobacillus fermentum, Lactobacillus rhamnosus, Serratia marcescens) in the stool of patients with Crohn's disease (CD) in the course of induction treatment with exclusive enteral nutrition (EEN) or anti-tumor necrosis factor alpha (Infliximab, IFX) vs. healthy controls (HC). MATERIALS/METHODS DNA was isolated from stool samples of CD (n = 122) and HC (n = 17), and quantitative real-time Polymerase Chain Reaction (qPCR) was applied. In both treatment groups, the first stool sample was taken before the start of treatment, and the second 4 weeks after its end: in EEN (n = 48; age (mean; SD) 13.35 ± 3.09 years) and IFX groups (n = 13; age (mean; SD) 13.09 ± 3.76 years). RESULTS The only species that showed a statistically significant difference between the two groups of patients before any therapeutic intervention was L. fermentum. Moreover, its number increased after completion of EEN and differed significantly when compared with the HC. In the IFX group the number of L. fermentum decreased during the therapy but was significantly higher than in the HC. The number of S. marcescens in the EEN group was significantly lower than in the controls both before and after EEN. CONCLUSION The implemented treatment (EEN or IFX) modifies the microbiome in CD patients, but does not make it become the same as in HC.

Abstract
Standard blood cultures require at least 24–120 h to be reported as preliminary positive. The objective of this study was to compare the reliability of Gram staining and fluorescent in-situ hybridization (FISH) for detecting bacteria in otherwise negative blood culture bottles. Ninety-six sets were taken from patients with a diagnosis of sepsis. Six incomplete blood culture sets and eight blood cultures sets demonstrating positive growth were excluded. We performed Gram stain and FISH on 82 sets taken from post-operative septic patients: 82 negative aerobic blood cultures, 82 anaerobic blood cultures, and 82 blood samples, as well as 57 blood samples taken from healthy volunteers. From the eighty-two blood sets analyzed from the septic patients, Gram stain visualized bacteria in 62.2% of blood samples, 35.4% of the negative aerobic bottles, and in 31.7% of the negative anaerobic bottles. Utilizing FISH, we detected bacteria in 75.6%, 56.1%, and 64.6% respectively. Among the blood samples from healthy volunteers, FISH detected bacteria in 64.9%, while Gram stain detected bacteria in only 38.6%. The time needed to obtain the study results using Gram stain was 1 h, for FISH 4 h, and for the culture method, considering the duration of growth, 5 days. Gram stain and FISH allow quick detection of bacteria in the blood taken directly from a patient. Finding phagocytosed bacteria, which were also detected among healthy individuals, confirms the hypothesis that blood microbiome exists.

Abstract
This study conducts a comparative phenotypic and genetic analysis of C. perfringens strains isolated from two patients hospitalized at the same time in 2017 in the surgical ward of the Provincial Specialist Hospital in Włocławek (Kujawsko-Pomorskie Province) who developed necrotizing soft tissue infections (NSTI). To explain the recurring cases of this infection, a comparative analysis was performed for these strains and the ones originating from infections recorded at the same hospital in three patients with gas gangrene in 2015. The two C. perfringens isolates studied in 2017 (8554/M/17 from patient No. 1 and 8567/M/17 from patient No. 2) had identical biochemical profiles. A comparison of research results using multiplex PCR from 2017 with a genetic analysis of strains from 2015 enabled us to demonstrate that the strains currently studied have the genes encoding the same toxins (α and β2) as the two strains analyzed in 2015: no. 7143 (patient No. 3) and no. 7149 (patient No. 2). A comparative analysis of the strain profiles obtained with pulsed-field gel electrophoresis (PFGE) in 2017 with the results from 2015 has found one identical and genetically unique restriction profile, corresponding to one clone of C. perfringens comprising of two strains: no. 8567/M/17 (patient No. 2 in 2017) and no. 7143 (patient No. 3 in 2015). The epidemiological data and detailed analysis of the course of both events suggest that this clone of C. perfringens possibly survived in adverse conditions of the external environment in the operating block of this hospital for many months.

Abstract
The gold standard in microbiological diagnostics of bacteremia is a blood culture in automated systems. This method may take several days and has low sensitivity. New screening methods that could quickly reveal the presence of bacteria would be extremely useful. The objective of this study was to estimate the effectiveness of these methods with respect to blood cultures in the context of antibiotic therapy. Blood samples from 92 children with sepsis were analyzed. Blood cultures were carried out in standard automated systems. Subsequently, FISH (Fluorescent In-Situ Hybridization) and nested multiplex-real-time-PCR (PCR) were performed. Blood cultures, FISH and PCR yielded positive results in 18%, 39.1%, and 71.7% of samples, respectively. Significant differences were found between the results obtained through culture before and after induction of antibiotherapy: 25.5% vs. 9.7%. There was no significant difference in FISH and PCR results in relation to antibiotics. The three methods employed demonstrated significant differences in detecting bacteria effectively. Time to obtain test results for FISH and PCR averaged 4–5 hours. FISH and PCR allow to detect bacteria in blood without prior culture. These methods had high sensitivity for the detection of bacteremia regardless of antibiotherapy. They provide more timely results as compared to automated blood culture, and may be useful as rapid screening tests in sepsis.

Abstract
The aim of this study was to determine if there are quantitative differences in Candida fungi between pediatric patients with Crohn’s disease (before and after exclusive enteral nutrition (EEN), and the biologic therapy with anti-tumor necrosis factor alpha – (IFX)), and healthy controls. DNA was isolated from fecal samples and PCR was used to determine the number of fungal cells. Both therapeutic interventions resulted in a statistically significant decrease in Pediatric Crohn’s Disease Activity Index. The numbers of Candida decreased during both therapeutic intervention but the difference was statistically significant for the IFX intervention only (p = 0.045). Moreover, fungi population in both study groups declined during intervention when compared to the control group but the difference was significant before treatment only in the IFX group (p = 0.013). The total distribution of Candida with both IFX and EEN as well as in the control group differed significantly (p = 0.01) before treatment only. No correlation between the numbers of Candida and disease activity as well as the following biochemical parameters: serum iron concentration, protein or glucose level were found. It cannot be ruled out that, in combination with genetic and immunological disorders, fungi can contribute to the initiation of the disease process and perpetuation of active inflammation.

Abstract
Introduction Scientific data indicate a possible influence of gut microbiota on the development of type 1 and type 2 diabetes mellitus (T1DM and T2DM, respectively). Sequence analysis of 16S ribosomal RNA identified several hundred bacterial species of the intestinal ecosystem, most of which cannot be cultured. Objectives We aimed to evaluate gut microbiota composition in adult patients with T1DM and T2DM and establish a link between microbiological test results and patients' clinical data. Patients and methods We examined DNA isolated from fecal samples in 3 groups: healthy volunteers (n = 23), patients with T1DM (n = 22), and patients with T2DM (n = 23). Next‑generation sequencing was performed on the MiSeq platform. Results At the phylum level, the Firmicutes bacteria prevailed (>77%) in all groups. At the taxonomic levels L2 (phylum) and L6 (genus), significant differences were demonstrated in bacterial profiles, particularly in the T2DM group. A negative correlation was observed between several genera of bacteria and the percentage of glycated hemoglobin A1c in the T2DM group, while a positive correlation was revealed between bacteria belonging to the genus Bifidobacterium and high‑density lipoprotein cholesterol levels in both T1DM and T2DM groups. Conclusions Our results provide grounds for conducting research in the field of gut microbiota in order to develop individualized therapy for patients with diabetes based on modifying the microbiota composition, as a new method for controlling glycemia. Next‑generation sequencing allows a rapid identification of the DNA of all bacteria present in the sample and their taxonomic classification.

Abstract
B-cell CLL/lymphoma 6 (BCL6) exerts oncogenic effects in several human hematopoietic malignancies including chronic myeloid leukemia (CML), where BCL6 expression was shown to be essential for CML stem cell survival and self-renewal during imatinib mesylate (IM) treatment. As several lines of evidence suggest that interferon γ (IFNγ) production in CML patients might have a central role in the response to tyrosine kinase inhibitor (TKI) therapy, we analyzed if IFNγ modulates BCL6 expression in CML cells. Although separate IFNγ or IM treatment only slightly upregulated BCL6 expression, combined treatment induced remarkable BCL6 upregulation in CML lines and primary human CD34+ CML stem cells. We proved that during combined treatment, inhibition of constitutive signal transducer and activator of transcription (STAT) 5 activation by IM allowed the specific enhancement of the STAT1 dependent, direct upregulation of BCL6 by IFNγ in CML cells. By using colony-forming assay, we found that IFNγ enhanced the ex vivo colony or cluster-forming capacity of human CML stem cells in the absence or presence of IM, respectively. Furthermore, inhibition of the transcriptional repressor function of BCL6 in the presence of IM and IFNγ almost completely blocked the cluster formation of human CML stem cells. On the other hand, by using small interfering RNA knockdown of BCL6, we demonstrated that in an IM-treated CML line the antiapoptotic effect of IFNγ was independent of BCL6 upregulation. We found that IFNγ also upregulated several antiapoptotic members of the BCL2 and BIRC gene families in CML cells, including the long isoform of MCL1, which proved to be essential for the antiapoptotic effect of IFNγ in an IM-treated CML line. Our results suggest that combination of TKIs with BCL6 and MCL1 inhibitors may potentially lead to the complete eradication of CML stem cells.

Abstract
Blood is considered to be a sterile microenvironment, in which bacteria appear only periodically. Previously used methods allowed only for the detection of either viable bacteria with low sensitivity or selected species of bacteria. The Next-Generation Sequencing method (NGS) enables the identification of all bacteria in the sample with their taxonomic classification. We used NGS for the analysis of blood samples from healthy volunteers (n = 23) and patients with sepsis (n = 62) to check whether any bacterial DNA exists in the blood of healthy people and to identify bacterial taxonomic profile in the blood of septic patients. The presence of bacterial DNA was found both in septic and healthy subjects; however, bacterial diversity was significantly different (P = 0.002) between the studied groups. Among healthy volunteers, a significant predominance of anaerobic bacteria (76.2 %), of which most were bacteria of the order Bifidobacteriales (73.0 %), was observed. In sepsis, the majority of detected taxa belonged to aerobic or microaerophilic microorganisms (75.1 %). The most striking difference was seen in the case of Actinobacteria phyla, the abundance of which was decreased in sepsis (P < 0.001) and Proteobacteria phyla which was decreased in the healthy volunteers (P < 0.001). Our research shows that bacterial DNA can be detected in the blood of healthy people and that its taxonomic composition is different from the one seen in septic patients. Detection of bacterial DNA in the blood of healthy people may suggest that bacteria continuously translocate into the blood, but not always cause sepsis; this observation can be called DNAemia.

Abstract
INTRODUCTION Lyme disease, caused by Borrelia burgdorferi, is a multisystem disease that often makes difficulties to recognize caused by their genetic heterogenity. Currently, the gold standard for the detection of Lyme disease (LD) is serologic diagnostics based mainly on tests: ELISA and Western blot (WB). These methods, however, are subject to consider- able defect, especially in the initial phase of infection due to the occurrence of so-called serological window period and low specificity. For this reason, they might be replaced by molecular methods, for example polymerase chain reaction (PCR), which should be more sensitivity and specificity. In the present study we attempt to optimize the PCR reaction conditions and enhance existing test sensitivity by applying the equivalent of real time PCR - nested PCR for detection B. burgdorferi DNA in the patient's blood. METHODS The study involved 94 blood samples of patients with suspected LD. From each sample, 1.5 ml of blood was used for the isolation of bacterial DNA and PCR real time am- plification and its equivalent, in nested version. The remaining part earmarked for serologi- cal testing. Optimization of the reaction conditions made experimentally, using gradient of the temperature and gradient of the magnesium ions concentration for reaction real time in nested-PCR and PCR version. RESULTS The results show that the nested-PCR real time, has a much higher sensitivity 45 (47.8%) of positive results for the detection of B. burgdorferi compared to the single- variety, without a preceding pre-amplification 2 (2.1%). Serological methods allowed the detection of infection in 41 (43.6%) samples. CONCLUSIONS These results support of the nested PCR method as a better molecular tool for the detection of B. burgdorferi infection than classical PCR real time reaction. The nested-PCR real time method may be considered as a complement to ELISA and WB mainly in the early stages of infection, when in the blood circulating B. burgdorferi cells. By contrast, the results of serological and molecular tests should always be carried out tak- ing into account the patient's clinical status.

Abstract
Background. Type 2 diabetes mellitus (T2DM) is determined by genetic and environmental factors. There have been many studies on the relationship between the composition of the gastrointestinal bacterial flora, T2DM, and obesity. There are no data, however, on the gut microbiome structure in monogenic forms of the disease including Maturity Onset Diabetes of the Young (MODY). Methods. The aim of the investigation was to compare the qualitative parameters of the colonic flora in patients with HNF1A-MODY and T2DM and healthy individuals. 16S sequencing of bacterial DNA isolated from the collected fecal samples using the MiSeq platform was performed. Results. There were significant between-group differences in the bacterial profile. At the phylum level, the amount of Proteobacteria was higher (p = 0.0006) and the amount of Bacteroidetes was lower (p = 0.0005) in T2DM group in comparison to the control group. In HNF1A-MODY group, the frequency of Bacteroidetes was lower than in the control group (p = 0.0143). At the order level, Turicibacterales was more abundant in HNF1A-MODY group than in T2DM group. Conclusions. It appears that there are differences in the gut microbiome composition between patients with HNF1A-MODY and type 2 diabetes. Further investigation on this matter should be conducted.

Abstract
Despite a significant civilization advancement, parasitic diseases still pose a serious diagnostic and therapeutic problem. Children's susceptibility to these infections stems from their immature immune system and lack of basic hygiene routines. The objective of the study was to evaluate the level of knowledge which parents of preschool children's possess about parasitic diseases in their children's environment. The study was carried out in the group of 151 parents of preschool children living both in the city and in the country. The survey was carried out by means of a diagnostic poll with the application of a self-designed research questionnaire. To make the evaluation even more objective, a special scale was created in which parents could score points for their answers (0 - wrong answer, 1 - correct answer). The total number of points ranging from 0 to 9 indicated an unsatisfactory level of knowledge, from 10 to 13 - satisfactory level, from 14 to 16 - good level and from 17 to 20 - very good level of parents' awareness. The results of the study reveal that the level of parents' knowledge about parasitic diseases is only satisfactory. A statistically significant relationship was observed between the variables such as education and sex. The higher education, the higher level of knowledge. Moreover, women were more knowledgeable in the field of parasitic diseases than men were. Financial status of the family did not influence the level of parents' awareness. Well-planned educational programmes might have a positive influence on developing proper hygiene routines in families, which, in turn, will limit the risk of spreading parasitoses in the population of children.

Abstract
Background Gastrointestinal tract microbiota, particularly bacterial microflora, seem to have a different qualitative and quantitative composition in both type 1 (T1DM) and type 2 diabetes (T2DM) mellitus cases as compared to non-diabetic individuals. So far, there are no data from diabetes research concerning the prevalence of fungi, particularly the most common genus, i.e. Candida, which are important components of human colon microflora. We aimed to examine whether there are quantitative changes of Candida fungi in the feces of patients with T1DM and T2DM as compared to healthy controls. Findings Overall, we included 44 diabetic patients (27 patients with T1DM and 17 with T2DM) as well as 17 healthy, non-diabetic controls. Feces and blood samples were collected from all study individuals. DNA was isolated from fecal samples and quantitative real time PCR (qPCR) was applied in order to determine the number of fungal cells. Statistical association with selected clinical and biochemical features was examined. There was a difference in the amount of Candida in the feces among the three examined groups (p = 0.007). Candida spp. populations in T1DM and T2DM subjects were larger as compared to controls (p = 0.017 and p = 0.037, respectively). However, no difference was found between T1DM and T2DM. No association was identified between the quantity of fungi and examined patients’ characteristics, except for negative correlation with blood lipid parameters in T2DM group. Conclusions Candida fungi appear to be more prevalent in the feces of patients with T1DM and T2DM. Their amount seems to be associated with serum lipids in T2DM patients. This initial finding requires further confirmation.

Abstract
The aim of the study is to determine the seroprevalence and risk factors for Toxoplasma gondii infection in women of reproductive age within the Małopolska province who were examined in the Laboratory of Microbiological Diagnostics, Chair of Microbiology in Cracow in 2013-2014. Seventy-eight questionnaires completed by women of reproductive age (mean age 29.91±6.56) were analysed. In total, 82% of respondents signed up for serological testing while already pregnant (33 patients in the age group 18-29 years and 30 patients in the age group 30-39 years). Twenty- seven percent had no previous contact with the parasite. A statistically significant (chi-square=7.722, p=0.005) correlation between permanent residence in the countryside and the presence of anti-T. gondii antibodies was found. A significant correlation was shown in the studied group between a lack of contact with soil and negative results of serological tests for toxoplasmosis (chi-square=4.116, p=0.042). The majority of the surveyed women had already encountered this parasite. It seems that special attention should be given to rural women. Implementation of more precise testing in the diagnosis of toxoplasmosis is also essential.

Abstract
INTRODUCTION Lyme disease is a multi-organ animal-borne disease caused by the spirochete Borrelia burgdorferi (Bb). OBJECTIVES As the pathogenesis of Lyme borreliosis is not fully understood, the study has been designed to examine levels of soluble vascular cell adhesion molecule-1 (sVCAM-1) and soluble intercellular adhesion molecule-1 (sICAM-1) in serum and the cerebrospinal fluid (CSF) of patients with Lyme borreliosis and their associations with clinical signs and symptoms and anti-Borrelia burgdorferi (anti-Bb) antibody titers. PATIENTS AND METHODS Sixty-four patients were enrolled in the study, including 39 patients treated for Lyme borreliosis and 25 without the disease (control group). In both groups sVCAM-1 and sICAM-1 levels were determined in serum and the CSF. RESULTS Mean serum sICAM-1 and sVCAM-1 levels were higher in patients with Lyme borreliosis than in the control group. Serum sICAM-1 levels were significantly lower among patients with results positive for immunoglobulin M seroreactivity with Bb than among those with negative antibody responses. In patients with Bb-specific serum immunoglobulin G (IgG) antibodies, significantly higher serum sICAM-1 levels were found. Higher sVCAM-1 and sICAM-1 levels in the CSF were observed in patients positive for anti-Bb IgG antibody titers in the CSF. CONCLUSIONS In patients with Lyme borreliosis, endothelial cell activation results in elevated levels of sICAM-1 and sVCAM-1 in serum and the CSF.

Abstract
BACKGROUND Lyme borreliosis is a zoonose which can be transmitted to the humans during Ixodes tick bite to the skin. The disease is caused by bacteria--spirochetes of the Borrelia species, classified as Borrelia burgdorferi strain. In Poland Lyme borreliosis is caused by Borrelia garinii, Borrelia afzelii and Borrelia burgdorferi sensu stricto. The presence of Borrelia spielmani was recently reported. MATERIAL AND METHODS The study included 249 patients diagnozed in University Hospital in Krakow due to suspicion of Lyme borreliosis in 2005-2008. Results of serologic tests against borreliosis were analized using Elisa tests (Mikrogen), positive tests were confirmed using Western blot tests (Biomedica). RESULTS It was found the high percentage of the antibodies in class IgM, which are important in acute phase of borreliosis, typical for Borrelia garinii, whereas in class IgG it was found the prevalence of protein typical for Borrelia afzellii and Borrelia burgdorferi sensu stricto. It was found the high prevalence of the presence VIsE reacting with IgG antibodies. It was noted the presence of Borrelia spielmani genostrain in Poland.

Abstract
The left part of the Epstein-Barr virus (EBV) genome exhibits a strong colinearity of structural and functional elements with the immunoglobulin (Ig) gene loci which is only partially reflected in nucleotide sequence homologies. We propose that this colinearity may be the result of an inter-dependent co-evolution of the immunoglobulin loci together with EBV. Our observation could help elucidating the mechanisms of somatic hypermutation, explaining the ability of EBV to accidentally cause tumors, and shedding more light on the general mechanisms of viral and organismal evolution. We suggest that persisting viruses served as a complement for the organismal germline like in a ping-pong game and outline The Ping-Pong Evolution Hypothesis.

Abstract
OBJECTIVE We report two Hungarian patients with familial hypocalciuric hypercalcemia (FHH) caused by a mutation of the calcium-sensing receptor (CaSR) at codon 55. The proband and her father were heterozygous for this mutation. DESIGN We performed detailed clinical and laboratory assessments of this family to characterize the effects of CaSR mutation on several endocrine organs expressing CaSR. RESULTS Interestingly, we could not detect any failure in the function of any tissues we examined, except in serum calcium levels. CONCLUSIONS To our knowledge, this has been the first report from Eastern and Central Europe showing P55 L mutation of the CaSR, as well as the first publication discussing the effect of this mutation on several endocrine systems containing CASR.

Abstract
The viral interleukin-10 promoter (vIL-10p), overlapping the rep* element in the Epstein-Barr virus (EBV) genome, is a promoter element active mostly in the late phase of the lytic cycle and immediately upon infection of B cells. rep* was, through transfection experiments with small plasmids, characterised as a cis element supporting oriP replicative function. In this study, in vivo protein binding and CpG methylation at rep*/vIL-10p were analysed in five cell lines that harbour strictly latent EBV genomes. Contrary to the invariably unmethylated dyad symmetry element (DS) of oriP, rep*/vIL-10p was highly methylated and showed only traces of protein binding in all examined cell lines. This result is in agreement with vIL-10p being an inactive promoter of EBV genomes, and makes it less likely that rep* functions as a replicative element of latent EBV genomes.

Abstract
We analysed the methylation patterns of CpG dinucleotides in a bidirectional promoter region (LRS, LMP 1 regulatory sequences) of latent Epstein-Barr virus (EBV) genomes using automated fluorescent genomic sequencing after bisulfite-induced modification of DNA. Transcripts for two latent membrane proteins, LMP 1 (a transforming protein) and LMP 2B, are initiated in this region in opposite directions. We found that B cell lines and a clone expressing LMP 1 carried EBV genomes with unmethylated or hypomethylated LRS, while highly methylated CpG dinucleotides were present at each position or at discrete sites and within hypermethylated regions in LMP 1 negative cells. Comparison of high resolution methylation maps suggests that CpG methylation-mediated direct interference with binding of nuclear factors LBF 2, 3, 7, AML1/LBF1, LBF5 and LBF6 or methylation of CpGs within an E-box sequence (where activators as well as repressors can bind) is not the major mechanism in silencing of the LMP 1 promoter. Although a role for CpG methylation within binding sites of Sp1 and 3, ATF/CRE and a sis-inducible factor (SIF) cannot be excluded, hypermethylation of LRS or regions within LRS in LMP 1 negative cells suggests a role for an indirect mechanism, via methylcytosine binding proteins, in silencing of the LMP 1 promoter.

Abstract
Epstein-Barr viral (EBV) latency-associated promoters Qp, Cp, and LMP1p are crucial for the regulated expression of the EBNA and LMP transcripts in dependence of the latency type. By transient transfection and in vitro binding analyses, many promoter elements and transcription factors have previously been shown to be involved in the activities of these promoters. However, the latency promoters have only partially been examined at the nucleotide level in vivo. Therefore, we undertook a comprehensive analysis of in vivo protein binding and CpG methylation patterns at these promoters in five representative cell lines and correlated the results with the known in vitro binding data and activities of these promoters from previous transfection experiments. Promoter activity inversely correlated with the methylation state of promoters, although Qp was a remarkable exception. Novel protein binding data were obtained for all promoters. For Cp, binding correlated well with promoter activity; for LMP1p and Qp, binding patterns looked similar regardless of promoter activity.

Abstract
Apart from the regulation of calcium metabolism, 1, 25-dihydroxyvitamin D(3) plays an essential role in cell proliferation and differentiation in several tissues. The vitamin D receptor (VDR) gene shows polymorphisms in humans that appear to be clinically significant in some pathological conditions. In the present study, the BsmI polymorphism of the VDR gene was studied in 59 Caucasian patients with rectal cancer (mean follow-up: 48 months). The relationship between VDR genotypes and the expression of oncogenes as well as their influence on survival were also investigated. VDR polymorphism was examined in tumor and normal mucosa cells by PCR technique. The expression of erbB-2/HER-2, p53, ras and epidermal growth factor receptor (EGFR) was also detected by immunohistochemistry and protein blotting. The presence of the VDR B allele significantly correlated with the overexpression of the erbB-2 oncogene. There was no difference in the VDR genotype between cancer and normal mucosal cells. Coexpression of erbB-2, pan-ras, p53 and EGFR internal and external domains was significantly higher in cancer cells than in normal mucosa. There was no significant correlation between VDR genotypes and age, gender, tumor infiltration depth, number and site of lymph node metastases and lymphatic or blood vessel infiltration. The VDR genotype alone did not influence survival. Overexpression of erbB-2 and EGFR was associated with a poor prognosis. In patients expressing only one oncogene in cancer cells, the presence of the VDR B allele showed a tendency to a poor prognosis. In conclusion, VDR gene BsmI polymorphism might affect the development and prognosis of rectal cancer by influencing erbB-2 oncogene expression.

Abstract
Latent episomal genomes of Epstein-Barr virus, a human gammaherpesvirus, represent a suitable model system for studying replication and methylation of chromosomal DNA in mammals. We analyzed the methylation patterns of CpG dinucleotides in the latent origin of DNA replication of Epstein-Barr virus using automated fluorescent genomic sequencing of bisulfite-modified DNA samples. We observed that the minimal origin of DNA replication was unmethylated in 8 well-characterized human cell lines or clones carrying latent Epstein-Barr virus genomes as well as in a prototype virus producer marmoset cell line. This observation suggests that unmethylated DNA domains can function as initiation sites or zones of DNA replication in human cells. Furthermore, 5' from this unmethylated region we observed focal points of de novo DNA methylation in nonrandom positions in the majority of Burkitt's lymphoma cell lines and clones studied while the corresponding CpG dinucleotides in viral genomes carried by lymphoblastoid cell lines and marmoset cells were completely unmethylated. Clustering of highly methylated CpG dinucleotides suggests that de novo methylation of unmethylated double-stranded episomal viral genomes starts at discrete founder sites in vivo. This is the first comparative high-resolution methylation analysis of a latent viral origin of DNA replication in human cells.

Abstract
The role of tumor necrosis factor-alpha in insulin resistance has been studied in 59 patients with Type 2 diabetes, 28 with android type obesity and 35 healthy lean controls. Immunoreactive concentrations and bioactivity of serum tumor necrosis factor-alpha have repeatedly been determined in 8 weeks intervals for 12 months, five times per patients, by using ELISA and L929 cell cytotoxicity bioassay. Significantly higher immunoreactive tumor necrosis factor-alpha concentrations and bioactivity have been found in both, the Type 2 diabetic and obese groups as compared to the healthy persons. Tumor necrosis factor-alpha concentrations and bioactivity have showed a significant positive linear correlation with the elevated basal serum C-peptide levels and body mass indexes in both groups of patients. According to these data the cytokine might play a role in insulin resistance in obesity as well in Type 2 diabetes.
