Probiotics as an Oyster Preservative?
Oysters are a culinary treat. Unfortunately after shucking, their freshness is limited, and the pathogen Vibrio vulnificus can proliferate. Vibrio vulnificus, related to the pathogen that causes cholera, can cause intestinal problems and skin infections. To prevent this problem, scientists from Mississippi have experimented with dipping the shucked oysters in solutions containing anti-microbial substances. Success was seen with solutions prepared with grape seed extract, citric acid or bacterially derived lactic acid. After dipping, shucked oysters stayed V. vulnificus-free for 20 days in a refrigerator. If the oysters actually tasted good at this point is another question.
Probiotic-enriched Formulas for Cow’s Milk Allergy
Allergies versus proteins found in cow’s milk develop in some infants. As the majority of milk products are from cows, companies first digest the proteins by hydrolysis to produce formulas for sensitive babies. A study performed in Belgium wished to determine if probiotic-enriched hydrolysates from whey would be a better option than those from milk casein. They found that while both formulas were effective in reducing allergy symptoms, the formula made from whey actually helped increase infant growth during the first year of life.
Mesalazine Plus Lactobacilli Good for Diverticulitis
Diverticulitis is a digestive disease that involves the formation of pouches within the bowel wall. The disease is active when these pouches become inflamed. To control the inflammation, drugs, like the anti-inflammatory mesalazine, are employed. Because probiotics are also effective at reducing inflammation in the intestines, Italian researchers examined if Lactobacillus casei DG could also help. After a year of treatment, they found that while both the probiotic and the drug were just as effective at preventing relapses (approximately 85% remained in remission), the combination of the two worked even better (100% remained in remission).
