Bacteriocin-like substance (BLS) production inAeromonas hydrophilawater isolates

Bacteriocin-like substance of Aeromonas hydrophila.

The genus Aeromonas comprises Gram negative rods found mainly in aquatical environments that may infect humans and animals (JM Janda 1991 Clin Microbiol Rev 4: 397-410). In humans, some Aeromonas species have been associated with intestinal and extraintestinal infections and enterotoxins, cytotoxins as well as invasive mechanisms have been incriminated in the development of illness in the host ...

Characteristics of a bacteriocin -like substance produced by Clostridium haemolyticum strain IRP - 135

Bacteriocin-like substance (melaninocin) from oral Bacteroides melaninogenicus.

A bacteriocin-like substance, designated melaninocin, was extracted from a strain of Bacteroides melaninogenicus by ultrasonic treatment and purified. Melaninocin was heat labile and was destroyed by digestion by several proteolytic enzymes. Among the oral indigenous microorganisms, Bacteroides, Actinomyces, and streptococci were found to be sensitive to melaninocin.

Determination of Acquired Resistance Profiles of Pseudomonas aeruginosa Isolates and Characterization of an Effective Bacteriocin-Like Inhibitory Substance (BLIS) Against These Isolates

BACKGROUND The emergence of pan-drug resistant strains (PDR) of Pseudomonas aeruginosa has led to renewed efforts to identify alternative agents, such as bacteriocins and bacteriocin-like inhibitory substances (BLISs). OBJECTIVES The aims of this study were to determine the acquired resistance profiles of multidrug-resistant (MDR), extensively drug-resistant (XDR), and PDR P. aeruginosa isola...

determination of acquired resistance profiles of pseudomonas aeruginosa isolates and characterization of an effective bacteriocin-like inhibitory substance (blis) against these isolates

conclusions this blis with broad-spectrum activity may be a potential agent for the treatment or control of drug-resistant strains of p. aeruginosa infection. results among the 96 isolates of p. aeruginosa, 2 (2.1%), 94 (97.9%), and 63 (65.6%) were non-mdr, mdr, and xdr, respectively, and 1 (1.1%) was pdr. the most effective antibiotics against these isolates were polymyxins and fosfomycin. a b...
