Evaluating scaling of capillary photo‐biofilm reactors for high cell density cultivation of mixed trophies artificial microbial consortia [PDF]

Engineering in Life Sciences, Volume 23, Issue 9, September 2023., 2023
Abstract Capillary biofilm reactors (CBRs) are attractive for growing photoautotrophic bacteria as they allow high cell‐density cultivation. Here, we evaluated the CBR system's suitability to grow an artificial consortium composed of Synechocystis sp. PCC 6803 and Pseudomonas sp. VBL120.

Biofilms [PDF]

Otolaryngologic Clinics of North America, 2010
Bacterial biofilms are 3-dimensional aggregates of bacteria that have been shown to play a major role in many chronic infections. Evidence is growing that bacterial biofilms may play a role in certain cases of recalcitrant chronic sinusitis that do not respond to traditional medical and surgical therapies. Novel therapies may have clinical applications

Comparison between clinical evaluations and laboratory findings and the impact of biofilm on antimicrobial susceptibility in vitro in canine otitis externa

Veterinary Dermatology, Volume 34, Issue 6, Page 586-596, December 2023., 2023
Background – In clinical practice, the diagnosis of otitis externa (OE) normally is based on otoscopic examination and cytological findings, followed by empirical treatment with topic drugs. Biofilm‐producing bacteria are frequently present in OE, even if its presence is often underdiagnosed. Hypothesis/Objectives – The primary aim of this study was to

Die Strukturaufklärung des ersten sex‐induzierenden Pheromons einer Kieselalge

Angewandte Chemie, Volume 135, Issue 43, October 23, 2023., 2023
Die Struktur eines Sexualpheromons, welches ein β‐sulfatiertes Aspartat enthält, wurde mittels Metabolomik, Isotopenmarkierung, Massenspektrometrie und NMR‐Spektroskopie aufgeklärt. Das Peptid‐Pheromon ist in femtomolaren Konzentrationen aktiv und synchronisiert die sexuelle Paarung in der Kieselalge Seminavis robusta.

Neutralisation der Auswirkungen des Virulenzfaktors LecA aus Pseudomonas aeruginosa auf Humanzellen durch neue glykomimetische Inhibitoren

Angewandte Chemie, Volume 135, Issue 7, February 6, 2023., 2023
Inhibition of the bacterial lectin LecA is an alternative option to treat infections with the ESKAPE pathogen Pseudomonas aeruginosa. Optimization of divalent LecA ligands yielded ligands with good drug‐like properties and high potency. Compound evaluation in functional cellular assays showed their ability to inhibit LecA‐mediated virulence ...

Mycobacterium biofilms

Biofilm, 2023
The genus Mycobacterium includes some of the deadliest pathogens of History (Mycobacterium tuberculosis, Mycobacterium leprae), but most of the species within the genus are environmental microorganisms. Because some of these nontuberculous mycobacteria (NTM) species can be human pathogens, the study of these mycobacterial biofilms has increased during ...

Biofilm dispersion [PDF]

Nature Reviews Microbiology, 2020
The formation of microbial biofilms enables single planktonic cells to assume a multicellular mode of growth. During dispersion, the final step of the biofilm life cycle, single cells egress from the biofilm to resume a planktonic lifestyle. As the planktonic state is considered to be more vulnerable to antimicrobial agents and immune responses ...

Staphylococcal Biofilms [PDF]

Microbiology Spectrum, 2008
ABSTRACTStaphylococci, with the leading speciesStaphylococcus aureusandStaphylococcus epidermidis, are the most frequent causes of infections on indwelling medical devices. The biofilm phenotype that those bacteria adopt during device-associated infection facilitates increased resistance to antibiotics and host immune defenses. This review presents and

Bacteriófagos no tratamento de feridas [PDF]

, 2010
As infecções bacterianas, particularmente as causadas por bactérias resistentes aos antibióticos, permanecem a principal causa de morte entre pacientes hospitalizados com queimaduras e feridas. Para além da terapêutica sistémica, um elemento-chave na

Deciphering Streptococcal Biofilms [PDF]

Microorganisms, 2020
Streptococci are a diverse group of bacteria, which are mostly commensals but also cause a considerable proportion of life-threatening infections. They colonize many different host niches such as the oral cavity, the respiratory, gastrointestinal, and urogenital tract.
