Introduction. Resistance to the macrolide antibiotics in Mycoplasma pneumoniae becomes non-negligible in terms of both the right therapy and diagnostic services. Molecular methods have attractive features for identification of Mycoplasma pneumoniae and its associated resistance mutations in the 23S ribosomal RNA (rRNA) .Hypothesis / Gap Statement. Sytem molecular diagnostics can automatically identify the macrolide-resistant M. pneumoniae.Aim. To assess the performance of automated molecular diagnostics system, GENECUBE Mycoplasma, in the detection of macrolide resistance mutations.Methodology related.
To evaluate whether the system can distinguish mutant from wild-type 23S rRNA, synthetic oligonucleotide mimic the mutations are known (high levels of macrolide resistance, mutation at position 2063 and 2064; the low level of macrolide resistance, mutation at position 2067) were tested. To evaluate the clinical oropharyngeal samples, purified nucleic acids obtained from M. pneumoniae-positive samples using the system of nine hospitals GENECUBE. After confirmation of the re-evaluation of the M. pneumoniae positive, Sanger-based sequencing of 23S rRNA and typing mutants using the Mycoplasma GENECUBE performed.Results. The system identifies all synthetic oligonucleotide reproducibly associated with high levels of macrolide resistance. error detection was only observed for A2067G (in 2 out of 10 measurements).
Point mutations in the 23S rRNA detected in 67 (26.9%) of the 249 confirmed M. pneumoniae-positive clinical samples. Mutations at positions 2063, 2064 and 2617 were observed in 65 (97.0%), 2 (3.0%) and 0 (0.0%) of 67 samples, respectively. Mutations at positions 2063 and 2064 are A2063G and A2064G, respectively. The results of using a mutant type Mycoplasma GENECUBE are in full agreement with the results of sequence-based typing.Conclusion. GENECUBE Mycoplasma is a reliable test for the identification of significant clinical macrolide-resistant M. pneumoniae.
Associated with Circulating DNA Exosom as biomarkers for Glioma
Cancer cells and non-cancer secrete exosomes, nanovesicle species known to carry the parent molecular signatures for communication between cells. Exosomes secreted by tumor cells carry molecules of DNA, RNA, and proteins that reflect abnormal cancer status. DNA is the master molecule that ultimately affect the function of RNA and protein. DNA aberrations can potentially cause cell malignancies. Chatter and differential sequence number exosomal DNA is useful as a biomarker of cancer characteristics.
As these changes are both related to a particular stage of cancer or due to clinical treatment, the DNA is valuable as a biomarker response exosomal diagnostic, prognostic, predictive, and therapeutic-intervention. Notably, exosomes can cross the blood-brain barrier intact and anatomical compartments by transcytosis. Thus, the cancer-specific molecules of the trademark can be detected in the systemic circulation of blood and other body fluids, including cerebrospinal fluid, with a non-invasive procedures or minimally invasive. This comprehensive highlights specific cancers modulation of DNA associated with exosomes that are useful as delivery biomarkers.
Through glioma large international projects including ICGC and TCGA, knowledge about the genomics of cancer circulating reached saturation point. Enabling this to improve patient outcomes now requires embedding a comprehensive genomic profiling in routine oncology practice.Towards this purpose, this study defined genomic features a clinically relevant biological and adult cancer through detailed curation and analysis of large genomic datasets, accumulated literature and biomarker-driven therapy in clinics and development.
Evaluation of GENECUBE Mycoplasma for the detection of macrolide-resistant Mycoplasma pneumoniae
Sex-biased polyparasitism in moose (Alces Alces) based on molecular analysis of faecal samples
Simultaneous infection with multiple parasites in the host species individuals often observed in wild populations. Understanding parasite species distribution across the population of wild animals is crucial basic and applied, because the parasite can have a pronounced effect on the dynamics of the host population. Here, we calculated the prevalence and species richness endoparasit in moose and sex-biased polyparasitism explored using PCR diagnostic methods coupled with DNA sequencing of deer faecal samples of Biebrza River valley, North-Eastern Poland. It is the largest elk population in Central Europe that have not been harvested for almost 20 years.
We also evaluate the appropriate quantity of stool to detect the DNA of the parasite species. Stool samples were screened for molecular markers of 10 different species of endoparasites. endoparasit high prevalence in the population studied. Almost all of the samples (98%) tested positive for at least one species of parasite, and we found polyparasitism in most individuals tested. The number of different species of parasite found in the individual ranges from 0 to 9. parasite species richness was significantly higher in men than in female individuals.
