Chemical Composition and Synergistic Antimicrobial Effects of Essential Oils From Four Commonly Used Satureja Species in Combination With Two Conventional Antibiotics

Chemistry &Biodiversity, EarlyView.
The chemical composition and the in vitro synergistic antimicrobial effects of four Satureja essential oils were investigated. Essential oils from Satureja montana and S. hortensis displayed strong antimicrobial effects, whereas S. calamintha and S. alpina exhibited relatively weaker antimicrobial activity.

The role of the host—Neutrophil biology

Periodontology 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 ...

Nonencapsulated Streptococcus pneumoniae: Emergence and Pathogenesis

mBio, 2016
While significant protection from pneumococcal disease has been achieved by the use of polysaccharide and polysaccharide-protein conjugate vaccines, capsule-independent protection has been limited by serotype replacement along with disease caused by ...

Drug-ResistantStreptococcus pneumoniae [PDF]

New England Journal of Medicine, 1996
To the Editor: since the first description of infection caused by β-lactam-resistant Streptococcus pneumoniae, the optimal empirical antibiotic therapy for patients with suspected meningitis caused by this microorganism has remained unknown. Hofmann et al. (Aug. 24 issue)1 reported a 25 percent prevalence of penicillin-resistant S.

Clerocidin selectively modifies the gyrase-DNA gate to induce irreversible and reversible DNA damage [PDF]

, 2008
Clerocidin (CL), a microbial diterpenoid, reacts with DNA via its epoxide group and stimulates DNA cleavage by type II DNA topoisomerases. The molecular basis of CL action is poorly understood.

Promising Prodiginins Biological Activities

Chemistry &Biodiversity, EarlyView.
ABSTRACT Prodiginins are a large family of at least 34 pyrrolic compounds, including the well‐studied red pigment prodigiosin. Prodiginins are produced by several microorganisms displaying broad biological activities, including antimicrobial, antiviral, antiparasitic, antiproliferative, and immunosuppressive activities.

Identification of Streptococcus pneumoniae

International Journal of Circumpolar Health, 2006
Objectives: Streptococcus pneumoniae, pneumococcus, is an importanthuman pathogen that causes both serious invasive infections, suchas septicaemia, meningitis and pneumonia, as well as mild upper respiratoryinfections. It also belongs to the normal nasopharyngeal microbialflora. The purpose of this study was to compare bacteriologicalphenotypic methods

Etiology of severe childhood pneumonia in the Gambia, West Africa, determined by conventional and molecular microbiological analyses of lung and pleural aspirate samples. [PDF]

, 2014
Molecular analyses of lung aspirates from Gambian children with severe pneumonia detected pathogens more frequently than did culture and showed a predominance of bacteria, principally Streptococcus pneumoniae, >75% being of serotypes covered by current ...

Disruption of salt bridge interactions in the inter‐domain cleft of the tubulin‐like protein FtsZ of Escherichia coli makes cells sensitive to the cell division inhibitor PC190723

Cytoskeleton, Volume 82, Issue 7, Page 415-431, July 2025.
Abstract FtsZ forms a ring‐like assembly at the site of division in bacteria. It is the first protein involved in the formation of the divisome complex to split the cell into two halves, indicating its importance in bacterial cell division. FtsZ is an attractive target for developing new anti‐microbial drugs to overcome the challenges of antibiotic ...
