The microbic pattern of osteomyelitic foci were analyzed in patients with chronic osteomyelitis on the AB Expression Analyzer by the 'BioMerieux" anaerobic cultivation and identification system (France). The osteomyelitis-focus microcenosis was shown to be of the mixed anaerobic-aerobic nature. Anaerobic microorganisms were isolated in 65.4% of examined patients and made 34% of the isolated bacterial cultures, which is indicative of an important role of anaerobes in the development and persistence of the purulent-inflammatory process in chronic osteomyelitis. Thus, it is feasible to prescribe the antibacterial drugs, which are active in respect to both aerobic and anaerobic bacteria.

Small, obligately anaerobic strains 13CB8C, 13CB11C, 13CB18C and 13GAM1G were isolated from a faecal sample in a patient with Parkinson's disease with a history of duodenal resection. After conducting a comprehensive polyphasic taxonomic analysis including genomic analysis, we propose the establishment of one new genus and four new species. The novel bacteria are sp.

Background: The rumen fluke, Calicophoron daubneyi, is the major paramphistome species infecting ruminants within Europe. Adult flukes reside within the rumen where they are in direct contact with a unique collection of microorganisms. Here, we report a 1.

Peri-implantitis associated with dental implants shares characteristics with destructive periodontal diseases. Both conditions are multifactorial and strongly correlated with the presence of microorganisms surrounding the prostheses or natural dentition. This study aimed to evaluate the antimicrobial activity and toxicity of a mucoadhesive hydrogel functionalized with aminochalcone (HAM-15) against Aggregatibacter actinomycetemcomitans, Fusobacterium periodonticum, Prevotella intermedia, Porphyromonas gingivalis, Tannerella forsythia, and Candida albicans.

The biomethanization of lignocellulosic wastes remains an inefficient and complex process due to lignin structures that hinder the hydrolysis step, therefore, some treatments are required. This work describes the addition of an enriched microbial consortium in the biomethanization of rice straw. The experiment was carried out in lab batch reactors following two strategies: (i) pretreatment of rice straw for 48 h using the enriched microbial consortium (dilution 1:100), and (ii) addition of this enriched microbial consortium (dilution 1:100) directly to the anaerobic reactors (bioaugmentation).

The unintended microbiological production of hydrogen sulphide (HS) poses a significant challenge in engineered systems, including sewage treatment plants, landfills and aquaculture systems. Although sulphur-rich amino acids and other substrates conducive to non-sulphate-based HS production are frequently present, the capacity and potential of various microorganisms to perform sulphate-free HS production remain unclear. In this study, we identify the identity, activity and genomic characteristics of bacteria that degrade cysteine to produce HS in anaerobic enrichment bioreactors seeded with material from aquaculture systems.
