Abstract
The noteworthy spread of carbapenem-resistant K. pneumoniae (CR-KP) isolates represents a significant safety threat. Determination of the carbapenemase genes incidence among CR-KP clinical isolates in Kafrelsheikh, Egypt. A total of 230 K. pneumoniae isolates were recovered from four hospitals in Kafrelsheikh, Egypt. Susceptibility testing was conducted using Kirby-Bauer method and automated-Vitek2 system. CR-KP isolates were tested using modified Hodge test (MHT) and combined disk synergy test. PCR and DNA sequencing were conducted for CR-KP isolates to recognize the included carbapenemase-genes. Out of 230 K. pneumoniae isolates, 50 isolates presented resistance to carbapenem (meropenem). All 50 CR-KP isolates were multidrug-resistant (MDR). Genes like blaNDM-1 and blaOXA-48 were the only detected genes among CR-KP with an incidence of 70.0% and 52.0%, respectively. Up to 74.0% of the tested isolates carried at least one of the two recorded genes, among them 48.0% co-harbored both blaNDM-1 and blaOXA-48 genes. The accession-numbers of sequenced blaNDM-1 and blaOXA-48 genes were MG594615 and MG594616, respectively. This study reported a high incidence of MDR profile with the emergence of blaNDM-1 and blaOXA-48 genes co-existence in CR-KP isolates in Kafrelsheikh, Egypt. Hence, more restrictions should be applied against the spread of such serious pathogens.
Highlights
Klebsiella pneumoniae (K. pneumoniae) is a member in Enterobacteriaceae family causing serious opportunistic hospital and community-associated infections[1,2,3]
Material and Methods Bacterial isolates A total of 230 non-duplicated K. pneumoniae clinical isolates were recovered from 1005 different clinical samples that were collected during the period from July 2015 to April 2016 from hospitalized patients in different four hospitals in Kafrelsheikh city; Egypt
The results of the standard biochemical tests, as well as the Vitek2® compact system revealed the presence of 230 K. pneumoniae isolates among the tested 1005 clinical samples
Summary
Klebsiella pneumoniae (K. pneumoniae) is a member in Enterobacteriaceae family causing serious opportunistic hospital and community-associated infections[1,2,3]. It is known as one of the most common MDR pathogens showing re-. The significant spread of MDR K. pneumoniae all over the world has led to extensive use of carbapenem as last-resort antibiotics for treating the infections caused by those pathogens. Conclusion: This study reported a high incidence of MDR profile with the emergence of blaNDM-1 and blaOXA-48 genes co-existence in CR-KP isolates in Kafrelsheikh, Egypt. Co-existence of NDM-1 and OXA-48 genes in Carbapenem Resistant Klebsiella pneumoniae clinical isolates in Kafrelsheikh, Egypt.
