Activity of Drug Combinations against Mycobacterium abscessus Grown in Aerobic and Hypoxic Conditions

open access: yesMicroorganisms, 2022
Infections caused by Mycobacterium abscessus (Mab), an environmental non-tuberculous mycobacterium, are difficult to eradicate from patients with pulmonary diseases such as cystic fibrosis and bronchiectasis even after years of antibiotic treatments.

An easy method for quantification of anaerobic and microaerobic gene expression with fluorescent reporter proteins

open access: yesBioTechniques, 2023
Fluorescent proteins, such as green fluorescent proteins, are invaluable tools for detecting and quantifying gene expression in high-throughput reporter gene assays. However, they introduce significant inaccuracies in studies involving microaerobiosis or

The role of the host—Neutrophil biology

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Transcriptomic Analysis of Listeria monocytogenes in Response to Bile Under Aerobic and Anaerobic Conditions

open access: yesFrontiers in Microbiology, 2021
Listeria monocytogenes is a gram-positive facultative anaerobic bacterium that causes the foodborne illness listeriosis. The pathogenesis of this bacterium depends on its survival in anaerobic, acidic, and bile conditions encountered throughout the ...

Streptomycin Action and Anaerobiosis [PDF]

open access: yesJournal of General Microbiology, 1965
SUMMARY: The question was asked whether the insensitivity to dihydrostreptomycin and streptomycin exhibited by facultatively anaerobic organisms growing strictly anaerobically could be due entirely to the lack of an anaerobic mechanism for the uptake of these antibiotics.

Proteome Response of Staphylococcus xylosus DSM 20266T to Anaerobiosis and Nitrite Exposure

open access: yesFrontiers in Microbiology, 2018
The viability and competitiveness of Staphylococcus xylosus in meat mostly depend on the ability to adapt itself to rapid oxygen and nutrients depletion during meat fermentation.

Haloferax volcanii Immersed Liquid Biofilms Develop Independently of Known Biofilm Machineries and Exhibit Rapid Honeycomb Pattern Formation

open access: yesmSphere, 2020
The ability to form biofilms is shared by many microorganisms, including archaea. Cells in a biofilm are encased in extracellular polymeric substances that typically include polysaccharides, proteins, and extracellular DNA, conferring protection while ...

Avaliação da porosidade e placa férrica de raízes de arroz cultivado em hipoxia Evaluation of porosity and iron plaque on rice roots grown under hypoxia

open access: yesRevista Brasileira de Ciência do Solo, 2010
A alta difusividade do oxigênio em diversos materiais dificulta a criação e, ou, manutenção de um ambiente livre de O2. As técnicas utilizadas são pouco eficientes na exclusão do O2 e, portanto, não expressam a condição do solo alagado.

Difficulties Associated with Small-Scale Production of Carbonic Maceration Wines

open access: yesFermentation, 2022
The aim of the work was to study the vinification by carbonic maceration carried out in small volume tanks, because the use of these deposits is necessary in scientific studies where repetitions are mandatory.
