Profiles of phenotype resistance to antibiotic other than β-lactams in Klebsiella pneumoniae ESBLs-producers, carrying blaSHV genes [PDF]

open access: yes, 2010
Extended spectrum β-lactamases production is one of the most common mechanism of resistance to extendedspectrum β-lactam antibiotics is increasing worldwide. Twenty five strains of Klebsiella pneumoniae isolated from clinicalspecimens were tested.

Antibiotic‐mediated immune modulation in periodontitis

open access: yesPeriodontology 2000, EarlyView.
Abstract Periodontitis is a chronic inflammatory disease affecting the supporting structures of the teeth. Although initiated by dysbiotic microbial communities, its progression is largely driven by the host's uncontrolled inflammatory response. While antibiotics have conventionally been employed in periodontitis therapy for their antimicrobial ...

Limited association between disinfectant use and either antibiotic or disinfectant susceptibility of Escherichia coli in both poultry and pig husbandry [PDF]

open access: yes, 2019
Background Farm disinfectants are widely used in primary production, but questions have been raised if their use can select for antimicrobial resistance.

An Unusual Case of Citrobacter koseri Infection During Pregnancy at 27 Weeks: A Case Report and Literature Review

open access: yesClinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Early prenatal screening at 26 + 6 weeks detected Citrobacter koseri vaginal colonization in an asymptomatic high‐risk gravida. Culture‐guided IV ceftazidime (susceptible per CLSI testing) eradicated the pathogen without maternal/fetal compromise.

Acute Suppurative Thyroiditis Caused by Escherichia coli in an Immunocompetent Adult: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Acute Suppurative Thyroiditis (AST) is a very rare disorder of the thyroid gland, accounting for less than 1% of all thyroid diseases, owing to the protective mechanisms of the thyroid gland, including its rich vascular supply, extensive lymphatic drainage, well‐developed capsule, and high iodine content.

Step-Wise Increase in Tigecycline Resistance in Klebsiella pneumoniae Associated with Mutations in ramR, lon and rpsJ. [PDF]

open access: yesPLoS ONE, 2016
Klebsiella pneumoniae is a gram-negative bacterium that causes numerous diseases, including pneumonia and urinary tract infections. An increase in multidrug resistance has complicated the treatment of these bacterial infections, and although tigecycline ...

Arbor Accidents and Asteroids

open access: yesClinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Nocardia infection should be considered in immunocompromised patients presenting with concurrent pulmonary and neurological symptoms. Species identification and antimicrobial susceptibility testing are crucial. Co‐trimoxazole is the first‐line treatment.
