Abstract


În cadrul investigaţiilor ce vizează izolarea şi identificarea monotulpinilor de lactobacterii intestinale s-a constatat că acestea reprezintă lactobacterii în diversă formă (bacili şi coci) ce aparţin familiilor Lactobailliaceae şi Streptococcaceae şi genurilor: Lactobacillus (33,29%), Lactococcus (19,32%), Streptococcus (22,51%) şi Enterococcus (24,86%). Conform activităţii antagoniste şi  capacităţii adezive sporite, acestea au demonstrat utilitate esenţială pentru organism. Cercetările în experimente model (pe purcei sugari) au depistat deosebire esenţială între nivelul cantitativ şi calitativ al bacteriilor din genurile Lactobacillus şi Enterococcus la animale cu simptome de disfuncţii diareice (diminuare cu 22,46, 26,71 şi 22,44% şi creştere cu 20,50, 18,47 şi 16,86% respectiv vârstei de 7, 15 şi 30 de zile), comparativ cu cele sănătoase. Concomitent, s-a dovedit că mărirea numărului de enterococi a avut caracter diferenţiat, pentru că s-a evidenţiat creştere numai la specia de Enterococcus fecalis, iar la specia Enterococcus faecium – diminuare. Prin aceasta s-a confirmat opinia despre rolul semnificativ al  lactobacteriilor în sănătatea organismului, deoarece în cazul patologiei intestinale are loc diminuarea cantitativă a celor cu proprietăţi utile şi sporirea celor de categorie condiţionat patogenă.

THE UTILITY SOME GENERES OF GUT BACTERIA AND THEIR SIGNIFICANCE IN THE ORGANISM HEALTH

The studies directed of isolation and to identify mono strains of intestinal lactobacteria have found these represent lactobacteria in diverse form (bacilli and cocci) that belong families Lactobailliaceae and Streptococcaceae and genres: Lactobacillus (33,29%), Lactococcus (19,32%), Streptococcus (22,51%) and Enterococcus (24,86%). According antagonistic activity and greater adhesive capacities they demonstrated essential utility for the organism. Research in model experiments (the piglets) detected essential difference between quantitative and qualitative level bacteria of the genus Lactobacillus and Enterococcus to animals with dysfunctions diarrheal symptoms (decreasing by 22.46, 26.71 and 22.44% growth 20.50, 18.47 and 16.86% respectively age of 7, 15 and 30 days), compared to the healthy. Concomitant it was shown to increase the number of Enterococci had differentiated character, because it evidenced growth only at species of Enterococcus faecalis, and decrease – species Enterococcus faecium. Through this it was confirmed opinion about the significant role of lactobacteria in the health of organism, because in the case of intestinal pathology quantitative reduction occurs those with useful properties and increasing - the category pathogenic conditioning.
