Abstract
Introduction Virulent bacteria are capable to create molecules that dynamically reduce the immune response of the host, so increased bacterial persistence and tissue damage. The virulence factors encoding genes of uropathogenic E. coli are localized on chromosomal gene clusters called “
Highlights
Virulent bacteria are capable to create molecules that dynamically reduce the immune response of the host, so increased bacterial persistence and tissue damage
Bacteriocin is one of these virulence factors. which is Proteinaceous toxins that produced via bacteria and have the ability to inhibit the growth of similar or closely related bacterial strain [5].Bacteriocins, a member of the narrow-spectrum toxins are described as the “microbial weapon of choice”, due to their abundance and diversity among producing bacteria[6]
The effect of Piper cubeba extract on Bacteriocin of uropathogenic isolates have not been compared before so in this study, we have been detection the effect of P. cubeba extracts on Bacteriocin of uropathogenic Escherichia coli
Summary
Virulent bacteria are capable to create molecules that dynamically reduce the immune response of the host, so increased bacterial persistence and tissue damage. Which is Proteinaceous toxins that produced via bacteria and have the ability to inhibit the growth of similar or closely related bacterial strain [5].Bacteriocins, a member of the narrow-spectrum toxins are described as the “microbial weapon of choice”, due to their abundance and diversity among producing bacteria[6]. They are similar to killing factors of yeast and paramecium but are structurally, functionally, and ecologically different. Attention to medicinal plant studies that focusing on inhibition of as a target activity is increase , several bioassays to assess virulence factors have develop for number of microorganisms, especially bacteria and yeast. The effect of Piper cubeba extract on Bacteriocin of uropathogenic isolates have not been compared before so in this study, we have been detection the effect of P. cubeba extracts on Bacteriocin of uropathogenic Escherichia coli
