Generation of new clones of multidrug resistant infectious foci of environmental, zoonotic and reverse zoonotic Enterococcus faecalis & faecium strains from cases of mastitis in cows privileged in Baghdad ecosystem reveal unsafe tricks. Medically important plants Blackcurrant, London Plane and Pine Buds are widely used for resolving these public health threats and hazards as powerful antimicrobial preparations. Totally sixty pooled milk samples were collected from apparently healthy (30 units) and infected (30 units) Cows from different regions of Abu-Ghraib during March until July (2019). Integrated units were checked by California mastitis test and a designed scheme was dependent for recovery of pathogenic Enterococci. Gram staining and catalase was proceeds. VITEK 2 (bioMérieux) technology ribbon biochemical identification system was used to segregate faecalis strain from faecium one. Group D Enterococci were confirmed by Lancefield’s serological grouping. Biofilm-formation assay was followed as an important biomarker clue for antibiotics resistance barriers. Modified Kirby-Bauer disc diffusion assay using Muller-Hinton agar was dependent for checking susceptibility of recovered strains to selected antibiotics Penicillin, Methicillin, Vancomycin, Amikacin & Ciprofloxacin. Watery & alcoholic extracts of selected plants were prepared according to recommendations of Codex international standards of Association of Official Agricultural Chemists (AOAC) & modified disc inhibition assay with determination of minimum inhibitory concentration (MIC titer) & minimum bactericidal concentration (MBC titer) were proceeds. Chi-square analysis via SPSS software was dependent. Qualified data descriptions regarding recovery of seventeen (28.33%) strains out of sixty samples in which, ten (16.66%) strains were recovered from mastitic milk units & seven (11.66%) strains were recovered from apparently abnormal milk units. Ten (16.66%) strains were confirmed as E. faecalis: Seven (11.66%) clones from mastitic milk units versus three (5%) clones from apparently abnormal milk units. Seven (11.66%) strains were confirmed as E. faecium: Five (8.33%) clones from mastitic milk units versus two (3.33%) clone from apparently abnormal milk units. All recovered strains were Gram-positive purple beaded cocci, Catalase negative, Lancefield group D & biofilm-producing. All strains were very resistant to all selected antibiotics. Diverse efficacy index was present among selected plants extracts in which, active ingredients index revealed powerful inhibitory level & titer for London Plane followed by Pine Buds then Blackcurrant against these powerful multidrug resistant recovered clones. In conclusion, frequency & distribution of pathogenic multidrug resistant foodborne Enterococci in our ecosystem represent privileged hazard chain of contamination that can be reduced or overcome by natural antimicrobial replacements like these extracts.
