Bifidobacterium animalis lactis HN019 (DR10) is a strain from Fonterra licensed to DuPont, which markets it as HOWARU Bifido.

[8] Fonterra has a yogurt that is sold in New Zealand called Symbio Probalance, where the strain is labelled as DR10.

Bifidobacterium animalis subspecies lactis BB-12 administered in combination with other probiotics has showed "a trend toward increased remission" in a study of 32 patients with ulcerative colitis.

lactis BB-12 is a bacterial subspecies within the animalis strain that exhibits rod-shaped structure and lacks catalase activity.

This is due to a variety of favorable technological characteristics such as its fermentation activity, high tolerance to air, stability, and resilience to acidic and bile environments, even in freeze-dried products.

[13][14] Some people, such as those with compromised immune systems, short bowel syndrome, central venous catheters, heart valve disease and premature infants, may be at higher risk for adverse events.

[15] Rarely, consumption of probiotics may cause bacteremia, and sepsis, potentially fatal infections in children with lowered immune systems or who are already critically ill.[16]
