Beta-lactam resistance mechanisms in gram-negative bacteria [PDF]

Beta-lactam antibiotics are commonly used to treat a variety of bacterial infections. Gram-negative bacteria have evolved several resistance mechanisms including altered permeability and beta-lactamase production.

Dendrimeric Antigens for Passive Mast Cell Activation in the Evaluation of Amoxicillin Allergy

Allergy, EarlyView.
DeAns with defined nanoscale structure reveal that conjugate size and determinant density govern IgE‐mediated effector‐cell activation in AX allergy. All DeAn generations bind to sIgE in inhibition immunoassay, but only larger DeAns trigger FcεRI‐dependent responses in mouse MC, huRBL‐2H3, and LUVA cells.

Successful Application of the Mast Cell Activation Test in Immediate Hypersensitivity to Amoxicillin

Allergy, EarlyView.
This study included 28 amoxicillin‐allergic patients and 11 healthy exposed controls. Mast cells were differentiated from CD34+ progenitors over 8 weeks using cytokine cocktails. The mast cell activation test involved sensitization with patient or control sera and stimulation with free amoxicillin or G4/G5‐AXO dendrimers with successfully activated ...

Carriage of antimicrobial‐resistant E. coli in urban stray cats (Felis catus)

Australian Veterinary Journal, EarlyView.
Antimicrobial resistance (AMR) in Escherichia coli is a growing concern in both human and veterinary medicine, driven by the inappropriate use of antimicrobials. Companion animals may act as community reservoirs and sentinels for antimicrobial‐resistant bacteria due to their close contact with humans and other animals.

Diagnosis and management of neutropenia in adults: Expert guidance

British Journal of Haematology, EarlyView.
Severe neutropenia can result from decreased production of neutrophil precursors in the bone marrow, as in the case of severe congenital neutropenia, or from increased utilization of neutrophils or their accelerated destruction as for drug‐induced neutropenia or autoimmune neutropenia. Severe chronic neutropenia increases susceptibility to bacterial or
