A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

open access: yesThe FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Tissue Resident Memory Cells: Friend or Foe?

open access: yesImmunology, EarlyView.
Tissue‐resident memory T cells (TRM cells) are specialised immune cells in barrier tissues like the lungs, skin and gut, providing rapid host defence and tumour surveillance. Their retention and differentiation are regulated by molecules such as CD69, CD103 and TGF‐β. Dysregulation of TRM cells can lead to chronic activation, driving conditions such as

The emergence of pathogens on fish in an impacted estuary and the role of non‐native piranhas in a potential bacterial infectious outbreak

open access: yesJournal of Fish Biology, EarlyView.
Abstract As many tropical aquatic ecosystems worldwide, the Doce River estuary (DRE, southeastern Brazil) has increasingly faced multiple anthropogenic threats, including deforestation, mining, species introduction and water management. The 2015 collapse of the Fundão iron ore tailings dam severely changed water properties and increased heavy metal ...

Sea Lice (Lepeophtheirus salmonis) Harbour Putative Fish Pathogens: Insights From Illumina and Nanopore Sequencing

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Ectoparasites that penetrate host skin can act as biological or mechanical vectors for pathogens and, in some cases, serve as reservoirs. Crustacean ectoparasites of fish are potential vectors of pathogens, which is especially relevant for obligate pathogens (e.g., Aeromonas salmonicida) with limited seawater survival. Sea lice (Lepeophtheirus

Indicators and Bacterial Diversity of Subclinical Mastitis in Iran's Industrial Cattle Farms. [PDF]

open access: yesVet Med Sci
In this study, the relationship between milk lactose and somatic cell count and the prevalence of bacterial agents of subclinical mastitis was investigated. Klebsiella spp. was identified as the most common pathogen and showed a pattern of antibiotic resistance.

Phage Therapy: Targeting the Gut Microbiota for the Treatment of Acute Pancreatitis

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Acute pancreatitis (AP) is a common clinical inflammatory condition whose severity is closely associated with both local pancreatic injury and systemic complications. Research indicates that gut microbiota dysbiosis and subsequent bacterial translocation can exacerbate disease progression via the gut–pancreas axis, representing a critical ...

Immune Evasion of Helicobacter pylori and Extra‐Gastric Cancer Risk

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Helicobacter pylori (H. pylori) is a group 1 gastric carcinogen that plays a significant role in extra‐gastric digestive system cancers. H. pylori disrupts host cell homeostasis through expression of virulence factors leading to immune evasion as well as persistent gastric mucosal colonization. H. pylori infection has been shown to play a role

Catheter‐Associated Urinary Tract Infections in Children: An Evidence‐Informed Narrative Review of Diagnosis, Management and Prevention

open access: yesJournal of Paediatrics and Child Health, EarlyView.
ABSTRACT Catheter‐associated urinary tract infections (CAUTI) are a common healthcare‐associated infection in children and a major contributor to increased morbidity, prolonged hospital stays and higher healthcare costs. This narrative review uses an evidence‐informed approach highlighting recent paediatric literature (2000–2025) to provide an overview

Autoimmunity and Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
In a microbe‐driven inflammatory environment, peptidyl‐arginine deiminase (PAD) enzymes from neutrophils and Porphyromonas gingivalis citrullinate both microbial and self‐antigens. B cell presentation of citrullinated or self‐mimicking epitopes activates T cells that assist B cells in antibody isotype switching, affinity maturation, epitope spreading ...
