Pleuropulmonary nocardiosis, an unusual radiological presentation: Case report

Radiology Case Reports, 2023
Nocardiosis is caused by strict aerobic filamentous bacteria of the genus Nocardia belonging to the order Actinomycetales with Actinomyces, Streptomyces and Mycobacterium. The radio-clinical presentation in the chest is often misleading. We report a case

Fecal Microbiome Alterations in Colorectal Cancer: A Systematic Review of Compositional Changes and Microbial Biomarkers

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Gut microbiome plays a crucial role in colorectal cancer development. The advanced sequencing techniques have the potential to complement current non‐invasive methods for early diagnosis and prevention of colorectal cancer. This includes conducting studies with robust statistical power and consistent, replicable methodologies, taking into consideration

Forces Shaping Diversity of Hydrogen Peroxide Detoxification Potential in Ocean Microbial Ecosystems

Environmental Microbiology, Volume 28, Issue 6, June 2026.
Marine microbes which lack catalases, like Prochlorococcus, depend on ‘helpers’, like catalase‐positive Alteromonas, for hydrogen peroxide detoxification. Our results indicate diverse and distinct distributions of catalases (katG, katE and manganese catalase) among community members.

Anticancer Potential of Piericidin A1 and Derivatives Isolated From Streptomyces sp. Associated With Palythoa variabilis From Brazilian Reefs

Chemistry &Biodiversity, Volume 23, Issue 4, April 2026.
A Streptomyces spp. strain, isolated from the zoantharian Palythoa variabilis, produces the complex I mitochondrial inhibitor piericidin A1 with effects on cancer cells proliferation and MTT‐formazan reduction at concentrations up to 0.1 aM. ABSTRACT Marine holobionts are an important source of bioactive natural products.

A New Genus of the Actinomycetales: Waksmania gen.nov. [PDF]

Journal of General Microbiology, 1957
SUMMARY: A single mesophilic species of a new genus belonging to the family Streptomycetaceae of the order Actinomycetales is described and has been named Waksmania (W. rosea, type species). It produces a filamentous growth which is differentiated into vegetative (primary) mycelium and aerial (secondary) mycelium. Hyphae are 1·5μ.

Peptidoglycan Cross-Linking in Glycopeptide-Resistant Actinomycetales [PDF]

Antimicrobial Agents and Chemotherapy, 2014
ABSTRACT Synthesis of peptidoglycan precursors ending in d -lactate ( d -Lac) is thought to be responsible for glycopeptide resistance in members of the order Actinomycetales that produce these drugs and in related soil bacteria.
