The sequences of the bla(TEM) genes encoding TEM-92 in Proteus mirabilis and Providencia stuartii isolates were determined and were found to be identical. Except for positions 218 (Lys-6) and 512 (Lys-104), the nucleotide sequence of bla(TEM-92) was identical to that of bla(TEM-20), including the sequence of the promoter region harboring a 135-bp deletion combined with a G-162-->T substitution. The deduced amino acid sequence of TEM-92 differed from that of TEM-52 by the presence of a substitution (Gln-6-->Lys) in the peptide signal.

Background: Metallo-beta lactamase resistance is one of the carbapenem resistances that worsen the world nowadays. A new variant of carbapenem-resistant has only limited reports from Africa including Ethiopia. This study aimed to determine Metallo -ß- lactamase resistance Gram-negative bacteria in Hawassa University Comprehensive Specialized Hospital January-June 2023.

Background: Worldwide, antimicrobial resistance (AMR) has grown to represent a serious threat to the diagnosis, management, and prevention of bacterial diseases. Due to their multidrug resistance attributes, the WHO has classified extended-spectrum-β-lactamase-producing Enterobacteriaceae (ESBL-PE)-associated infections as infections of critical significance, posing a serious risk to human health. Thus, the goal of this systematic review and meta-analysis was to assess the pooled prevalence of ESBL-PE and AMR among strains causing clinical infections in Africa.

This case report describes an elderly man with a history of recurrent urinary tract infections and obstructive pyelonephritis with struvite stones caused by Proteus mirabilis. Despite appropriate antibiotic treatment, the stones increased in size, necessitating alternative therapy. This case highlights the use of ascorbic acid to lower the urine pH, which contributes to the dissolution of struvite stones.

Urinary catheters serve as critical medical devices in clinical practice. However, the currently used urinary catheters lack efficient antibacterial and lubricating properties, often leading to discomfort with patients and even severe urinary infections. Herein, a new strategy of supramolecular assembly and disassembly of chitosan (Cs) is developed that enables efficient antibacterial lubricous and biodegradable hydrogel urinary catheters.
