Lysogeny in Leuconostocs

Nihon Chikusan Gakkaiho, 1980
Lactic streptococciおよびlactobacilliの溶原性についていくつかの報告が行われているが,leuconostoc菌種の溶原性についての報告は,著者らが知るかぎりにおいて見い出せない.本報告は,leuconostoc菌種の溶原性の検索を目的としleuconostoc 32菌株をマイトマイシンC処理により,その溶原性の有無を調べた.Leuconostoc菌株の溶原性のマイトマイシンCによる誘発は,その濃度に大きく依存しまたマイトマイシンCに対する感受性は,leuconostoc菌株によってことなった.Leuconostoc菌株を培養し対数期初期にマイトマイシンCを液体培地1ml当り最終濃度0.5μgおよび5.0μg加えて溶原菌株の誘発を行った.Leuconostoc ...

Lysogeny In Coagulase-Negative Staphylococci [PDF]

Journal of Medical Microbiology, 1971
Summary Lysogenicity in coagulase-negative staphylococci was tested by incubating the strains in the presence of Mitomycin C. Among 173 strains examined, 45 were found to release phage. Twenty-eight of these phages were obtained from 90 strains belonging to Staphylococcus epidermidis biotype 1 (Baird-Parker, 1965).

Different gut microbiome dysbioses impact the evolutionary fate of hypervirulent Klebsiella pneumoniae

iMeta, EarlyView.
Transient exposure to ampicillin results in restructuring of microbiota to favor oxygen‐tolerant bacteria, whereas osmotic laxative perturbation preserves Bacteriodota. Ampicillin‐ but not laxative‐exposed environment favors establishment of rmpA phase variants that lost hypermucoviscosity but short‐chain fatty acids present in the laxative‐exposed gut

Controlling Growth of Ultrasmall Sub‐10 nm Silver Nanoparticles From Cotinus coggygria Scop. Extract and Evaluation of Its In Vitro Anti‐Breast Cancer, Antioxidant and Antimicrobial Activity

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study highlights the potential use of Cotinus coggygria Scop. plant extract in a single‐step synthesis of biocompatible and ultrasmall AgNPs for in vitro applications. Herein, microscopic analyses revealed that AgNP exposure did not induce appreciable morphological changes in CRL‐4010 cells, whereas MCF‐7 and MDA‐MB‐231 cells exhibited ...

Human Group A Streptococci Virulence Genes in Bovine Group C Streptococci

Emerging Infectious Diseases, 2010
Phage-encoded virulence genes of group A streptococci were detected in 10 (55.6%) of 18 isolates of group C streptococci that had caused bovine mastitis.

Time‐Resolved Effects of Cold Atmospheric Plasma on E. coli GW‐AmxH19 Transcriptome and Proteome in an Emulated Wastewater Environment

PROTEOMICS, EarlyView.
ABSTRACT Cold atmospheric plasma (CAP) is effective against a variety of microorganisms. Here, we described effects on an Escherichia coli strain isolated from hospital wastewater caused by treatment with physical plasma. E. coli GW‐AmxH19 was incubated in artificial wastewater and treated for 15 min with CAP.

Structural and Stability Analysis of de Novo Designed Proteins Incorporating a Plant Self‐Incompatibility Motif

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Artificial protein design enables the creation of stable scaffolds beyond those evolved in nature. Incorporation of native functional motifs into de novo scaffolds provides a promising strategy to mimic natural interactions while altering structural frameworks.

Combined application of Bacillus velezensis JDB15 and Trichoderma harzianum JDL4 suppresses banana Fusarium wilt under controlled conditions

Pest Management Science, EarlyView.
The surfactin C secreted by JDB15 and the probable parasitism of JDL4 lead to the leakage of intracellular macromolecules and the degradation of hyphae, respectively. Combined application of the two strains effectively controls banana Fusarium wilt under controlled conditions.

Programmable 3D Microfluidics Reveals Motility‐Driven Antibiotic Resistance Evolution in Gradients

Small, EarlyView.
Using a programmable microfluidic platform, this study shows that bacterial motility is crucial for resistance development in heterogeneous antibiotic landscapes. Motile Escherichia coli randomly migrates along antibiotic gradients, and sufficient movement is required for resistance to emerge.

High Incidence of Lysogeny in the Oxygen Minimum Zones of the Arabian Sea (Southwest Coast of India)

Viruses, 2018
Though microbial processes in the oxygen minimum zones (OMZs) of the Arabian Sea (AS) are well documented, prokaryote-virus interactions are less known.
