Crystal structure and biophysical characterisation of the enterococcal foldase PpiC, a cross‐opsonic antigen against gram‐positive nosocomial pathogens

The FEBS Journal, Volume 292, Issue 20, Page 5475-5490, October 2025.
PpiC is an enterococcal lipoprotein endowed with both Peptidyl‐prolyl cis‐trans isomerase (PPIase) and foldase activities. It is a potential target for novel antimicrobials and a promising vaccine antigen. We determined the crystal structure of the enzyme, showing that PpiC adopts a dimeric organisation embedding two catalytic parvulin‐type PPIase ...

Effect of a ceruminolytic ear cleaner on clinical, microbiological and ear canal microbiome evolution in canine erythemato‐ceruminous otitis externa associated with proliferation of Malassezia yeasts

Veterinary Dermatology, Volume 36, Issue 5, Page 668-678, October 2025.
Background – Erythemato‐ceruminous otitis externa (ECOE) is commonly associated with Malassezia spp. and microbial imbalance. Hypothesis/Objective – To assess the clinical performance of an ear cleaner in dogs suffering from ECOE associated with Malassezia spp. overgrowth and to measure its impact on the microbiota. Conclusions and Clinical Relevance –

On Combining Conventional Point‐To‐Point and Automated Waste Collection Systems

Networks, Volume 86, Issue 2, Page 174-198, September 2025.
ABSTRACT The global demand for sustainable waste management has spurred initiatives to improve the efficiency of urban waste collection, discussing the advantages and disadvantages of different systems. We analyze a new combined waste collection problem that uses two systems simultaneously: a point‐to‐point system, in which waste is collected using ...

Solving Turán's Tetrahedron Problem for the ℓ2-Norm

, 2022
Turán's famous tetrahedron problem is to compute the Turán density of the tetrahedron K34. This is equivalent to determining the maximum ℓ1-norm of the codegree vector of a K34-free n-vertex 3-uniform hypergraph.

Pyrosequencing-based analysis reveals a novel capsular gene cluster in a KPC-producing Klebsiella pneumoniae clinical isolate identified in Brazil

BMC Microbiology, 2012
Background An important virulence factor of Klebsiella pneumoniae is the production of capsular polysaccharide (CPS), a thick mucus layer that allows for evasion of the host's defense and creates a barrier against antibacterial peptides.
