The full name of Lactobacillus Bulgaricus has been recently changed to Lactobacillus delbrueckii subspecies Bulgaricus and is the main bacteria used for the product of the original Bulgarian yoghurt known for its positive health effects. The reason this lactic bacteria is named after the country name Bulgaria is because it only lives in its natural form on the territory of Bulgaria. Any products claiming to contain Lactobacillus Bulgaricus and not manufactured in Bulgaria and very unlikely to contain the original and non-genetically modified Lactobacillus Bulgaricus.
Lactobacillus Bulgaricus was first isolated by the Bulgarian scientist Stamen Grigoroff in 1905. Prior to that it was well known that the Bulgarian yoghurt had very positive effects on the human’s health and its healing properties were famous, but it was unknown due to what reason those effects occurred. The Bulgarian yoghurt was also famous for prolonging the life of the population who consumed the product. * One of the important uses of Lactobacillus Bulgaricus is making yogurt. It helps in this process by fermenting lactose. Another important function of Lactobacillus Bulgaricus is its ability to break down special enzymes like lactose in the body. This breaking down of enzymes helps the digestive process, especially for people who are lactose intolerant. * This helpful bacteria also helps other beneficial bacteria to grow which helps the immune system. * It can also help to metabolize lipids and keep cholesterol levels at a healthy level. * It can stop many infections in the body because of its antibiotic properties.
It does this by producing acid which keeps out many bad bacteria. * Another way it keeps bad bacteria from over populating is by clinging on the intestinal walls. If these “friendly” bacteria cover the walls, then the bad bacteria that cause diseases will not be able to live here. Streptococcus pneumonia Pneumococcus, (Streptococcus pneumoniae), spheroidal bacterium in the family Streptococcaceae that causes human diseases such as pneumonia, sinusitis, otitis media, and meningitis.
It is microbiologically characterized as a gram-positive coccus, 0. 5 to 1. 25 ? m (micrometre; 1 ? m = 10-6 metre) in diameter, often found in a chain configuration and surrounded by a capsule consisting of complex carbohydrate (polysaccharide). Many serological types have been differentiated. Pneumococci normally occur in the upper respiratory tract. Pneumococci have proved useful in elucidating microbial genetics. The phenomenon of transformation—an alteration of one cell by another—was first observed in these organisms in 1928.
Colonies formed by pneumococci usually are small, round, and smooth. Occasional mutant rough colonies are produced by organisms that cannot synthesize the capsular material. When a rough colony is grown in the presence of genetic material (deoxyribonucleic acid) from a smooth colony, the rough colony is transformed into a smooth one. Pneumococci are separated into types depending on the specific capsular polysaccharide formed.
The disease-causing ability of pneumococci resides in the capsule, which delays or prevents their destruction by phagocytes, cells in the bloodstream that normally engulf foreign material. Pneumonia caused by pneumococcus occurs in about 1 in 1,000 adults each year. Pneumococcal infection can affect anybody. However, young children, older people and some other groups of people are at increased risk of developing a pneumococcal infection. Drug resistance is a major concern with any bacteria.
Streptococcus pneumoniae has developed resistance to many drugs, making it particularly problematic. In the 1960s, scientists discovered a strain of penicillin-resistant streptococcus pneumoniae which has since spread throughout the world. In most instances, strains of the bacteria that are penicillin-resistant are also resistant to other medications like erythromycin, chloramphenicol, trimethoprim-sulfamethoxazole and tetracycline. These strains are referred to as “multidrug resistant. “
