In vitro inhibitory effect of cranberry (Vaccinium macrocarpum Ait.) juice on pathogenic microorganisms

Antimicrobial effects of fractions from cranberry products on the growth of seven pathogenic bacteria

“…These results confirm that cranberry antimicrobial properties are not just based upon a low pH. However, Magarinos et al (2008) reported an inhibitory activity against S. aureus with clarified juice. Differences among results may be related to many experimental variances such as bacterial strains, and source, as well as the methodology employed for the essay.…”

Antimicrobial effect of cranberry juice and extracts

“…Results presented in Table 2 indicate that at pH 7.0, none of the juice concentrations had an antimicrobial effect on the tested pathogens. These results differ somewhat from those of Leitao et al (2005) and Magarinos et al (2008) who, when using an agar-well diffusion method, did report an inhibitory activity against S. aureus with CJ. Differences among results may be related to many experimental variances such as bacterial strains, and source, as well as the methodology employed for the essay.…”

In Vivo and In Vitro Antibacterial Activities of Cranberry Extract against E. coli O157:H7 in Urinary Tract Infected Rats

“…It is now widely thought that cranberry PACs prevent bacteria from adhering to the uroepithelium of the bladder, thereby blocking the ability of E. coli to infect the urinary mucosa and easily excreted out the body, these results agree with more recent research showed that the uniquely structured proanthocyanidins (PAC) present in cranberry inhibit the adherence of pathogenic P-fimbriated Escherichia coli (Lavigne et al, 2008;Pinzon et al, 2009). Also these findings are supported by the results of Magarinos et al (2008) who found that concentrated Cranberry juice has antibacterial activity especially on uropathogenic bacteria.…”
