Of note, when the 260 pneumonia isolates were compared with the 220 bacteremia strains of urinary tract origin, they were still distinguishable in terms of phylogroups/subgroups and virulence factor content (Appendix).
The adverse effect of ADPRT activity of exoS on host cell includes cell death, disruption of actin cytoskeletal and inhibition of DNA synthesis.21 The GAP activity is required for the anti-phagocytic effect of exoS.25 The in vitro analysis of virulence factors of P.
The traT and iss genes which encoded important virulence factors that are linked with human serum resistance were genetically scanned by using PCR technique for recognition of the existence of these genes in 26 isolates of Enterobacteriaceae family, it was found that 21(80.7%) of Enterobacterial isolates were contained traT gene at 288bp while only 17(65.38%) of isolates were contained iss gene at 258bp.
coli pathotypes have emerged overtime through the transfer of virulence factors from other bacterial species by way of mobile genetic elements such as pathogenicity islands, transposons, and plasmids (7).
The high level of drug resistance seen among the bacterial isolates causing neonatal infection in the study might be linked to the possession of some virulence factors. In response to antibiotics exposure, bacteria usually activate regulatory systems responsible for controlling the expression of genes involved in the conversion of the drugs to harmless compounds [20].

Besides the aforementioned virulence factors SDSE isolates have C5a peptidase, glyceraldehyde 3-phosphate dehydrogenase, and hyaluronidase [10].
