Global phylogeography and genetic characterization of carbapenem and ceftazidime-avibactam resistant KPC-33-producing Pseudomonas aeruginosa.

Ceftazidime-avibactam (CZA) is currently one of the last resorts used to treat infections caused by carbapenem-resistant Enterobacteriaceae and Pseudomonas aeruginosa. However, KPC variants have become the main mechanism mediating CZA resistance in KPC-producing gram-negative bacteria after increasing the application of CZA. Our previous study revealed that CZA-resistant KPC-33 had emerged in carbapenem-resistant P.

Genetic profiling of extended-spectrum β-Lactamase and carbapenemase-producing Escherichia coli O157:H7 from clinical samples among diarrheal patients in Shashemene, Ethiopia.

Background: Escherichia coli (E. coli) O157:H7, associated with diarrhea, poses a global health risk. In Ethiopia, where diarrhea is common, there is limited knowledge about these resistant strains and a lack of data on Extended-Spectrum β-Lactamase (ESBL) and carbapenemase production.

AS3MT Gene Variant Shows Association with Skin Lesions in an Arsenic Exposed Population of India.

AS3MT, GSTO2, and GSTP1 genes play important roles in the arsenic biotransformation pathway, while CYP2E1 gene has a prominent role in the metabolic activation of xenobiotics. Hence, polymorphisms of these genes might have an effect on arsenic biotransformation and could impact susceptibility to arsenical skin lesions in individuals of chronic arsenic toxicity. The present case-control study, comprising 148 subjects, attempted to evaluate genetic association between nine polymorphisms of AS3MT, GSTO2, GSTP1 and CYP2E1 genes and arsenical skin lesions in a West Bengal (WB) population.

Emerging threats: Antimicrobial resistance in extended-spectrum beta-lactamase and carbapenem-resistant Escherichia coli.

Antimicrobial resistance (AMR) in Escherichia coli strains, particularly those producing Extended-Spectrum Beta-Lactamase (ESBL) and Carbapenemase (CR-Ec), represents a serious global health threat. These resistant strains have been associated with increased morbidity, mortality, and healthcare costs, as they limit the effectiveness of standard antibiotic therapies. The prevalence of ESBL- and CR-Ec-producing strains continues to rise, driven by the overuse and misuse of antibiotics in healthcare and agricultural settings, and facilitated by global interconnectedness through international travel, trade, and food distribution.

Introduction Chronic obstructive pulmonary disease (COPD) is a significant contributor to global morbidity and mortality. Despite well-established management protocols, treatment remains suboptimal due to high costs and mortality rates. This study aims to compare the impact of initial oxygenation status, Dyspnea, Eosinopenia, Consolidation, Acidemia, and Atrial Fibrillation (DECAF), and National Early Warning Score 2 (NEWS2) scores on management outcomes in COPD patients.

Genomic characterization of ST11-KL25 hypervirulent KPC-2-producing multidrug-resistant from China.

The global prevalence of ST11 hypervirulent carbapenem-resistant (hv-CRKP) isolates has been increasingly documented, yet genomic characterization of this clone remains insufficiently explored. Here, we report a clinical ST11-KL25 hv-CRKP strain (KP156) that exhibited resistance to multiple antibiotics and demonstrated hypervirulence in a mouse infection model. Whole-genome sequencing revealed that KP156 harbored one virulence plasmid (pKP156-Vir) and two resistance plasmids (pKP156-KPC and pKP156-tetA).

Seronegative and Low Seropositive Treatment-Naive Secondary Syphilis in India: A Cross Sectional Study.

The non-treponemal tests like VDRL and RPR hold an important place in the diagnosis of syphilis. In many countries, these tests are used for screening, with positive results being subsequently confirmed by treponemal or specific tests like TPHA or FTA-ABS. Recent observations of low-titer VDRL or RPR positivity (<1:8) or negative results in patients with clinically active syphilis are becoming a cause for concern especially in the backdrop of a resurgence of the disease.
