Background and Aim: Klebsiella pneumoniae is an important Gram-negative rod-shape bacillus often causes range of infections to human. It is ubiquitous to different environments owing its ability to develop specific niche adaptation. The emergence of highly drug-resistant strains is particularly intriguing. K. pneumoniae is a serious public health threatening pathogen. Here, antibiotic resistant genes and virulent factors of circulating ESBL-producing strains isolated from Sudanese patients will be assessed. Methods: The prevalence of the virulence factors and genotypes of CTX-M subgroups, TEM and SHV genes in clinical isolates and their correlation with the degree drug-resistance will be investigated. Thus, antibiotic susceptibility profile, (mrkD, K2, magA, entB and rmpA) and the molecular structures of drug resistant genes (TEM, SHV, CTX-M) of K. pneumoniae isolates will be studied thoroughly to get more insights. Sub-genotypes of ESBLs and virulent factors will be determined by analyzing the whole-genome sequencing by adopting Illumina Next-generation sequencing approach and compare it with K. pneumonie database. Results: We will expect to find different genes of ESBL-producing K. pneumoniae and virulence genes, genomic analysis will identify various antibiotic resistance genes associated with resistance to b-lactams, aminoglycosides, fluoroquinolones, macrolide, lincosamide and streptogramins, rifampicin, sulfonamides, trimethoprim, phenicols and tetracycline and We expect the presence of virulence genes in ESBL-producing K. pneumoniae. Conclusions: Following the outcome of the present study a clear understanding of the relationship between the virulence factors and multi-drug resistance in K. pneumoniae will be expected. Hence, it can be very helpful to manage a strategy to overcome the infections caused by K. pneumoniae.
