The ethanol and methanol extracts of P. crispus were tested against various Gram-negative and Gram-positive bacteria, such as Enterobacter hormaechei, P. aeruginosa, E. coli, Streptococcus pyogenes, S. aureus, and Enterococcus casseliflavus. The extracts exhibited zones of inhibition between 13 and 25 mm and were compared to the positive controls; ciprofloxacin, tetracycline, erythromycin, and penicillin (Lupoae et al. 2015). In a study by Fareed et al. (2008), four different extracts from P. crispus were prepared, namely ethanol, methanol, chloroform, and an aqueous extract. These were tested against various bacterial and fungal strains such as E. coli, P. aeruginosa, P. vulgaris, Salmonella cholerasuis, Shigella sp., K. pneumoniae, Serratia liquefaciens, Brenneria nigrifluens, B. subtilis 1020, B. cereus 1080, Erwinia carotovora NCPPB 312, S. aureus, C. albicans, Candida tropicalis, Aspergillus niger, Fusarium oxysporum, and Penicillium italicum. The extracts showed zones of inhibition values between 0 and 48 mm on the various strains of bacteria and fungi (Fareed et al. 2008).
Balance of saccharolysis and proteolysis underpins improvements in stool quality induced by adding a fiber bundle containing bound polyphenols to either hydrolyzed meat or grain-rich foods

As when added to the HM food, addition of the fiber bundle to the GR food appeared to modulate the abundances of several bacterial genera known to be involved in saccharolytic fermentation or polyphenol catabolism but also to impact a few that have been documented to have detrimental impact on gastrointestinal health (Figure 3b). Genus level OTUs increased by fiber addition to GR include the presumed saccharolytic or polyphenol catabolizing genera Blautia, Colinsella, Roseburia, Succinivibrio, and Brenneria as well as unknown genera in the families Veillonellaceae, Enterobacteriaceae, and Lachnospiraceae. Genus level OTUs decreased by fiber added to GR include the presumed saccharolytic genera Dialister, two in the family Enterobacteriaceae, and an unknown genus in the family Ruminococcaceae; genera with presumed detrimental impact on GI health via proteolytic or inflammatory activity (Peptococcus and Peptostreptococcus, as well as an unclassified genera from the family Desulfovibrionaceae and from the order Fusobacteriales); and genera with possible detrimental effects on health through acute pathogenic blooms (Yersinia, Flexispira, and Plesiomonas). As noted above for the HM Fiber food, few of the OTU changes were dependent on health status. Only Colinsella and Roseburia were significantly increased in healthy dogs, with no significant change in dogs with chronic enteritis/gastroenteritis (p = 0.014 and p = 0.022, respectively, for difference by health status; Table S4). An additional OTU (Ruminococcus; OTU 110221) showed no overall significant change across all dogs but was significantly increased by the addition of fiber to the GR food in healthy dogs but not dogs with chronic enteritis/gastroenteritis (p = 0.022 for difference by health status; Table S4).
