Comments "Most oral bacteria are destroyed by gastric acid leaving only a few surviving species, so that the gastric concentration usually is less than 10^3 colony forming units/ml (cfu/ml) (primary source). The microflora of the stomach is gram-positive and aerobic and the most commonly isolated species are streptococci, staphylococci, lactobacilli, and various fungi (4)." cfu=colony forming unit
