This study primarily aimed to significantly contnbute on the possibility of reducing the morbidity and mortality rates due to incorrect blood transfusion and shoitage of blood supply by exploring the potential for the conversion of blood type A to O, which is consideied the universal donor. This study focused on the use of Bifidobacterium longum, (obtained from Pine Fiee ^e Dried Bifidobacterium powder, Pro-LSB food supplement tablets, and a commercially available yogurt grown in a Bifidobacterium Selective Media (BSM) agar,) which contains an enzyme endo-alpha-Nacetylgalactosaminidase that may specifically convert blood type A red cells to blood type O. Each sample from the three different sources was mixed with 5 drops of blood type A and tested for their effect. Each prepared blood sample with the Bifidobacterium longum was incubated and checked for their agglutination at an interval of 5 minutes, JOminutes, 60 minutes, 1,440 minutes (24 hours) and 2,880 minutes (48 hours). The resulting blood type was determined through the use of an anti-sera and the absence of agglutination after the reaction of the enzyme is indicative for blood Type O. The results showed that the longer the bacteria and blood are exposed together, the agglutination decreases greatly from a strong agglutinate to a weaker agglutinate. Though it has been observed that this idea can be conceivably developed further, it is suggested by the researchers that more tests, experiments, variables and factors be considered to fully determine its mechanism in converting a specific blood typ UR - https://library.feu-nrmf.ph/cgi-bin/koha/opac-retrieve-file.pl?id=7008a3a08a0d7b4ffcf4019bec972a00 ER -
