Summary, etc. Carbapenem-resistant Klebsiella pneumoniae (CR-KP) infections are considered a global critical concern, causing a serious threat to public health. CR-KP strains have been widely disseminated worldwide in recent years, affecting countries with varying income levels, including low-, middle-, and upper-income countries. The incidence of CR-KP infections is tremendously increasing in developing countries, such as Egypt, posing a significant threat to public health.<br/>Ninety-four clinically significant K. pneumoniae isolates were collected from two tertiary care Egyptian hospitals: Al-Kasr Al-Ainy hospital, Cairo, Egypt and Memorial Souad Kafafi University hospital, Giza, Egypt over one year. All collected isolates were subcultured, and their identification as K. pneumoniae ssp. pneumoniae was confirmed via the automated VITEK® 2 system and the MALDI-TOF MS. Antimicrobial susceptibility testing (AST) of all tested K. pneumoniae isolates was examined using the Kirby-Bauer disk diffusion method and MICs were determined by the automated VITEK® 2 system, then confirmed for imipenem, meropenem, and colistin via the routine broth microdilution method. Subsequently, phenotypic detection of carbapenemases, as well as genotypic detection of major carbapenemase-encoding genes were carried out.<br/>Based on the automated VITEK® 2 system's AST results, all clinical K. pneumoniae isolates were multidrug-resistant (MDR). The highest detected resistance patterns were toward β- lactam antibiotics, followed by quinolones and aminoglycosides, where the prevalence of carbapenems resistance was too high, with 94.68% of isolates being resistant to imipenem with MICs >16 µg/ml. Phenotypic assays showed that 98.9% of CR-KP isolates produced carbapenemase(s), while PCR technique revealed that 97.9% of tested isolates harbored at least one carbapenemase-encoding gene. BlastN analysis of the sequenced PCR products against GenBank's non-redundant genome sequences showed that the blaOXA-48 gene was the most predominant carbapenemase-encoding genotype among our isolates, found in 89/94 of the tested isolates (94.7%), followed by blaNDM-1 (65/94, 69.1%) and blaKPC-2 (5/94, 5.3%). Additionally, the co-existence of both blaOXA-48 and blaNDM-1 carbapenemase genes in certain isolates (67%) was also observed.<br/>The high prevalence of carbapenem resistance and the terrifying spread of their encoding genes among K. pneumoniae isolates in Egypt are alarming, leading to limitations in the available<br/>therapeutic options for the management of these serious infections. Carbapenemases of the blaOXA-<br/>48 and blaNDM-1 genotypes are widespread in Egyptian healthcare settings, causing the current increase in carbapenem-resistant bacteria.
