Characterization of Pilin A and Thioredoxin A Mutant Strains of Acinetobacter baumannii, From a Transposon Insertion Library, for Pili Production and Virulence‐Associated Properties

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Acinetobacter baumannii transposon insertion mutant strains ΔpilA and ΔtrxA display marked reductions of surface pili. The PilA (a major pilin protein) and TrxA (thioredoxin A) deficient bacteria also show attenuation in pathogenesis including the reduction of intestinal bacterial attachment, increased phagocytic uptake and decreased mortality from ...

Electron Transport Chain Is Biochemically Linked to Pilus Assembly Required for Polymicrobial Interactions and Biofilm Formation in the Gram-Positive Actinobacterium Actinomyces oris. [PDF]

, 2017
The Gram-positive actinobacteria Actinomyces spp. are key colonizers in the development of oral biofilms due to the inherent ability of Actinomyces to adhere to receptor polysaccharides on the surface of oral streptococci and host cells.

Corynebacterium bovis Surgical Site Infection and Abscess Formation: A Case Report

Clinical Case Reports, Volume 13, Issue 11, November 2025.
ABSTRACT Corynebacterium bovis is primarily known for causing mastitis in cows. C. bovis infection in humans is quite rare with only 11 cases reported in the United States and 26 globally. A 69‐year‐old female presented with a left lower eyelid abscess following removal of a retained suture after bilateral upper and lower blepharoplasty.

Molecular Characterisation of Fungi Populations in the Chronic Wounds of Filarial Lymphedema Patients in Southern Ghana: A Cross‐Sectional Study

Health Science Reports, Volume 8, Issue 11, November 2025.
ABSTRACT Background and Aims Lymphatic filariasis (LF) and associated chronic wounds are of public health concern worldwide. Despite the significant burden of lymphatic filariasis (LF) and its associated chronic wounds, the fungal component of the wound microbiome remains poorly understood. Previous research has primarily focused on bacterial pathogens,

Outbreak with clonally related isolates of Corynebacterium ulcerans in a group of water rats [PDF]

, 2015
BACKGROUND: The zoonotic bacterium Corynebacterium ulcerans may be pathogenic both in humans and animals: toxigenic strains can cause diphtheria or diphtheria-like disease in humans via diphtheria toxin, while strains producing the dermonecrotic exotoxin

Impact of NLRP1 Met1154Val and IL1B variants on gestational malaria: an unexplored role of NLRP1 in inflammasome activation by Plasmodium spp.

The Journal of Pathology, Volume 267, Issue 3, Page 304-314, November 2025.
Abstract We hypothesized that variants in inflammasome‐related genes could influence susceptibility to gestational malaria (GM). To test this, we conducted an association study in a cohort of pregnant women from a malaria‐endemic region in northern Brazil, assessing whether specific functional single nucleotide variants (SNVs) in inflammasome genes ...
