Study the Effect of Human –Derived Probiotic Bacteria on the Viability of Blastocystis

Abstract

The purpose of this study was evaluation the quality of Lactobacillus acidophilus as probiotic in the treatment of Blastocystis hominis at various incubation periods, bacterial dilutions, and status. Blastocystis hominis was isolated from stool samples with diarrhea using parasitological diagnostic procedures, three bacterial dilutions (1:1, 1:2, and 1:3) and status (supernatant, pellet, and dead bacteria) were prepared in De Man Rogosa Sharpe broth, (MRS), then treated Blastocystis hominis rby adding Lactobacillus acidophilus dilutions and status and incubating it three periods (24 hr, 48 hr, and 72 hr), Blastocystis hominis counted.

Findings revealed that Lactobacillus acidophilus had the ability to treat Blastocystistocystis, by block the action and reduce the count with high significant differences, also the axenic cultures, showed Blastocystis inhibition by supernatant, pellet, and dead of Lactobacillus acidophilus from the 1st day of co-incubation, compared with control samples.
