Pancreatic cancer (PC) remains a global health concern with high mortality and is expected to increase as a proportion of overall cancer cases in the coming years. Most patients are diagnosed at a late stage of disease progression, which contributes to the extremely low 5-year survival rates. Presently, screening for PC remains costly and time consuming, precluding the use of widespread testing. Biomarkers have been explored as an option by which to ameliorate this situation. The authors conducted a search of available literature on PubMed to present the current state of understanding as it pertains to the use of microbial biomarkers and their associations with PC. Carriage of certain bacteria in the oral cavity (e.g., Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Streptococcus sp.), gut (e.g., Helicobacter pylori, Synergistetes, Proteobacteria), and pancreas (e.g., Fusobacterium sp., Enterobacteriaceae, Pseudomonadaceae) has been associated with an increased risk of developing PC. Additionally, the fungal genus Malassezia has likewise been associated with PC development. This review further outlines potential oncogenic mechanisms involved in the microbial-associated development of PC.

AbstractFree-living microorganisms with streamlined genomes are very abundant in the environment. Genome streamlining results in losses in the cell’s biosynthetic potential generating physiological dependencies between microorganisms. However, there exists no consensus on the specificity of these microbial associations. To verify specificity and extent of these associations, mixed cultures were established from three different freshwater environments. These cultures contained free-living streamlined organisms lacking multiple biosynthetic pathways. Among the co-occurring members of the mixed cultures, there was no clear recurring pattern of metabolic complementarity and dependencies. This, together with weak temporal co-occurrence patterns observed using time-series metagenomics, suggests that free-living freshwater bacteria form loose and unspecific cooperative loops. Comparative genomics suggests that the proportion of accessory genes in populations of streamlined bacteria allows for flexibility in interaction partners. Altogether this renders these free-living bacterial lineages functionally versatile despite their streamlining tendencies.

Rationale The relevance of ventilator-associated respiratory tract infections in severe injury patients (SIP) is associated with both features of causative pathogens and the initial severity of the state of patients. Among causative pathogens nosocomial flora is dominant. Purpose - to perform an analysis of the microbiological monitoring of ventilator-associated respiratory tract infections in SIP. The analysis was based on the results of a prospective epidemiological, clinical, and instrumental study of 100 SIP with ventilator-associated respiratory tract infections, stayed in the surgical intensive care unit. The proportion of ventilator-associated respiratory infections in the structure of nosocomial infections in these patients is between 90 - 95%, at that there was revealed the prevalence of nosocomial pneumonia (61%). Ventilator-associated respiratory tract infection most commonly occurs during the first 10 days of mechanical ventilation. The prevailing flora was represented by Gram negative Acinetobacter baumamnnii (40.3 ± 2.1%) and Pseudomonas aeruginosa (38.4% ± 3.2%). Isolated microorganisms possessed multiple antibiotic resistance, with the greatest extent to aminoglycosides - 69.5%, fluoroquinolones - 40.3%, penicillin - 37.6%; cephalosporins (third generation) - 33.8%. There is noted marked preponderance of microbial associations compared with monocultures 57.1 ± 5.3%.
