Adult blowflies, Calliphora vicina Robineau-Desvoidy, are exposed to bacteria-laden decay as adults and larvae. They are protected from infections in such habitats by a family of lytic proteins called Cecropins. In this study, we explore the relationshipbetween the developmental stages of the blowfly and the strength of the immune response when insulted by an endogenous pathogen, Echerichia col...

the ability of uropathogenic e. coli (upec) to cause symptomatic uti is associated with the expression of a variety of virulence factors. biofilm formation enables upec to resist the flow of urine and increases its tolerance to antimicrobials and the host immune response. the measurement of biofilm formation in vitro is affected by the type of culture medium used. the aim of this study was to e...

A mouse model of cystitis caused by uropathogenic Escherichia coli was used to study the distribution of gallium in bladder tissue following oral administration of gallium maltolate during urinary tract infection. The median concentration of gallium in homogenized bladder tissue from infected mice was 1.93 μg/g after daily administration of gallium maltolate for 5 days. Synchrotron X-ray fluore...

BACKGROUND Pathogenic strains in Escherichia coli can be divided into several pathotypes according to their virulence features. Among them, uropathogenic E. coli causes most of the urinary tract infections and has a genotype distinct from other virulent strains of E. coli. In this study, we sequenced and analyzed the genome of E. coli NCCP15653 isolated from the feces of a diarrhea patient in 2...

urinary tract infection (uti) is a neonatal life threatening infection which is usually treated with ampicillin plus an aminoglycoside or a third-generation cephalosporin. recently, growing number of escherchia coli species resistant to ampicillin and aminoglycosides have raised concerns regarding the necessity to change the empirical therapy. this motivates us to determine neonatal uti clinica...

The objective of this work was the phylogenetic characterization of local clinical isolates of uropathogenic E. coli with respect to drug resistance. A total of 59 uropathogenic E. coli responsible for community acquired urinary tract infections were included in this study. A triplex PCR was employed to segregate each isolate into four different phylogenetic groups (A, B1, B2 and D). Drug resis...

background and objectives: urinary tract infection (uti) is one of the most common infections in human, and uropathogenic escherichia coli (upec) strains are the most common cause of uti. these strains colonize in bladder and cause cystitis, which could cause pyelonephritis by movement to the kidneys. since fimh protein has a very important role in colonization of upec strains and causing infec...

Antibiotic resistant and biofilm forming uropathogenic Enterobacteriaceae are rising. This study was conducted to evaluate the efflux pump plasmid mediated genes in ciprofloxacin (CIP) hospital acquired Escherichia coli Klebsiella pneumoniae. Also, assess anti-biofilm action of carbonyl cyanide m-chlorophenylhydrazone (CCCP). Uropathogenic E. K. pneumoniae isolates were collected from Mansoura ...

b ackground: the prevalence of urinary tract infection (uti) is really high in the world. escherichia coli is a major agent of uti. one of the strategies for decreasing uti infections is vaccine development. as the attachment is a really important stage in colonization and infection, at- tachment inhibition has an applied strategy.  fimh protein is a major factor during bacterial colonization i...
