Assessment of the anti-pathogenic effects of condensed tannin extracts using scanning electron microscopy

چکیده
Two different types of condensed tannins (CTs), which were extracted and purified from tilia (Tilia L.) black locust (Robinia pseudoacacia), studied tested against two kinds bacteria, including Gram-negative Gram-positive, avian pathogenic E. coli (APEC) Staphylococcus epidermidis (S. epidermidis) respectively, by minimal bactericidal concentrations (MBCs) scanning electron microscopy (SEM). Both CT extracts significantly effective (p ≤ 0.05) at MBCs 5–10 mg CT/ml APEC (Gram-negative), 1.25–5 on S. (Gram-positive). This indicated that the CTs more potent Gram-positive than bacteria. Further, SEM revealed caused mainly morphological deformations bacterial cells some conjoined cell growth.
