Selection for Phase Variation of LOS Biosynthetic Genes Frequently Occurs in Progression of Non-Typeable Haemophilus influenzae Infection from the Nasopharynx to the Middle Ear of Human Patients

open access: yesPLoS ONE, 2014
Surface structures in Haemophilus influenzae are subject to rapid ON/OFF switching of expression, a process termed phase variation. We analyse tetranucleotide repeats controlling phase variation in lipo-oligosaccharide (LOS) genes of H.

Repeat Intraocular Sampling and Microbiological Testing in Infectious Endophthalmitis: A 27‐Year Prospective Observational Study at an Australian Statewide Tertiary Referral Centre

open access: yesClinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Endophthalmitis requiring multiple ocular tissue sampling for microbiological testing is uncommon and has not been previously studied. This study aims to analyse cases with at least two ocular tissue samplings and testing of different ocular samples against culture yields. Methods A 27‐year prospective observational study using data

Prevalence and Nationality Distribution of Known and Novel Genetic Variants in Children With Primary Ciliary Dyskinesia in the State of Qatar

open access: yesClinical Genetics, EarlyView.
CT scan image of a 17‐year‐old female with primary ciliary dyskinesia (PCD) showing dextrocardia and bilateral bronchiectasis. The study describes genetic mutations affecting patients with PCD in Qatar and the corresponding clinical phenotype of affected patients.

Infections in Chronic Lymphocytic Leukemia: Evolving Risks and Prevention Strategies

open access: yesEuropean Journal of Haematology, EarlyView.
ABSTRACT Infections remain a leading cause of morbidity and mortality in patients with chronic lymphocytic leukemia (CLL), reflecting both intrinsic immune dysfunction and therapy‐related immunosuppression. The pathogenesis of immunodeficiency in CLL is multifactorial: neoplastic B cells impair humoral immunity, T cells are functionally exhausted, and ...

From the microbiome to the central nervous system, an update on the epidemiology and pathogenesis of bacterial meningitis in childhood [version 1; referees: 3 approved] [PDF]

open access: yes, 2017
In the past century, advances in antibiotics and vaccination have dramatically altered the incidence and clinical outcomes of bacterial meningitis. We review the shifting epidemiology of meningitis in children, including after the implementation of ...

Molecular basis of antibiotic sensing by the TetR family regulator CecR – a structural perspective

open access: yesThe FEBS Journal, EarlyView.
Escherichia coli CecR, a member of the TetR family regulators, senses selected antibiotics and activates the expression of a putative drug efflux pump. Although present in many pathogenic Enterobacteriales strains, CecR remains poorly characterized. We present the first CecR crystal structure, which reveals a unique tunnel‐like ligand‐binding cavity ...
