I was able to find Bacteriofagos Lactobacilos capsules at the Pharmacy Counter at a Farmacity on Cabildo in Belgrano. The brand name is 'Totalflora' and it is produced by Roux-Ocefa. It came in a box of 30 capsules and the formula consists of: lactobacillus acidophilus, bifidobacterium bifidum, bacillus subtilis etc.... They kept them in the refrigerator at the pharmacy and even sent them home with me in a pouch with a small icepack. The hardest part was trying to get them to understand me. The male pharmacist didn't know what I was talking about and the female understood right away, so be persistent and ask more than one person. It think it was around $30 Pesos. Good Luck!
