Information: - Clostridium is a genus of Gram-positive bacteria, which includes several significant human pathogens, including the causative agent of botulism and an important cause of diarrhea, "Clostridium difficile". They are obligate anaerobes capable of producing endospores. The normal, reproducing cells of "Clostridium", called the vegetative form, are rod-shaped, which gives them their name, from the Greek or spindle. "Clostridium" endospores have a distinct bowling pin or bottle shape, distinguishing them from other bacterial endospores, which are usually ovoid in shape. "Clostridium" species inhabit soils and the intestinal tract of animals, including humans. "Clostridium" is a normal inhabitant of the healthy lower reproductive tract of women. - The Firmicutes (Latin: "firmus", strong, and "cutis", skin, referring to the cell wall) are a phylum of bacteria, most of which have Gram-positive cell wall structure. A few, however, such as "Megasphaera", "Pectinatus", "Selenomonas" and "Zymophilus", have a porous pseudo-outer membrane that causes them to stain Gram-negative. Scientists once classified the Firmicutes to include all Gram-positive bacteria, but have recently defined them to be of a core group of related forms called the low-G+C group, in contrast to the Actinobacteria. They have round cells, called cocci (singular coccus), or rod-like forms (bacillus). - Peptostreptococcaceae is a family of Gram positive bacteria in the class Clostridia . - The Clostridia are a highly polyphyletic class of Firmicutes, including "Clostridium" and other similar genera. They are distinguished from the Bacilli by lacking aerobic respiration. They are obligate anaerobes and oxygen is toxic to them. Species of the genus "Clostridium" are often but not always Gram-positive (see "Halanaerobium hydrogenoformans") and have the ability to form spores. Studies show they are not a monophyletic group, and their relationships are not entirely certain. Currently, most are placed in a single order called Clostridiales, but this is not a natural group and is likely to be redefined in the future. - Bacilli refers to a taxonomic class of bacteria. It includes two orders, Bacillales and Lactobacillales, which contain several well-known pathogens such as "Bacillus anthracis" (the cause of anthrax). All "Bacilli" are gram-positive bacteria.

Information: - The 1928 Summer Olympics (Dutch: "Olympische Zomerspelen 1928"), officially known as the Games of the IX Olympiad, was an international multi-sport event which was celebrated in 1928 in Amsterdam, Netherlands. Amsterdam had bid for the 1920 and 1924 Olympic Games, but had to give way to wartorn Antwerp, Belgium, and Pierre de Coubertin's Paris, respectively. The only other candidate city for the 1928 Games was Los Angeles, which would host the Olympics four years later. - Count Carl Clarence von Rosen (May 12, 1867, Stockholm August 12, 1955) was a Swedish athlete, military officer, and Crown Equerry to the King of Sweden. He became a member of the International Olympic Committee in 1900, and was credited for the re-introduction of Equestrian at the Summer Olympics after it was dropped at the 1904 Olympic Games. He competed in many sports, such as bandy (which he introduced to Sweden), ice hockey, football, lawn tennis and ice skating. - Clarence von Rosen , Jr. ( November 10 , 1903 -- July 7 , 1933 ) was a Swedish horse rider who competed in the 1932 Summer Olympics . In 1932 he and his horse Sunnyside Maid won the bronze medal in the individual eventing . At the same Olympics he also won the bronze medal in the individual jumping competition with his horse Empire . In both events the Swedish team was not able to complete the competition with three riders , therefore he was unable to win team medals . He was the son of Clarence von Rosen . - Los Angeles (Spanish for "The Angels"), officially the City of Los Angeles and often known by its initials L.A., is the second-most populous city in the United States (after New York City), the most populous city in California and the county seat of Los Angeles County. Situated in Southern California, Los Angeles is known for its mediterranean climate, ethnic diversity, sprawling metropolis, and as a major center of the American entertainment industry. Los Angeles lies in a large coastal basin surrounded on three sides by mountains reaching up to and over . - Stockholm (or ) is the capital of Sweden and the most populous city in the Nordic countries; 932,917 people live in the municipality, approximately 1.5 million in the urban area, and 2.3 million in the metropolitan area. The city is spread across 14 islands on the coast in the southeast of Sweden at the mouth of Lake Malaren, by the Stockholm archipelago and the Baltic Sea. The area has been settled since the Stone Age, in the 6th millennium BC, and was founded as a city in 1252 by a Swedish statesman Birger Jarl. It is also the capital of Stockholm County. - Equestrianism made its Summer Olympics debut at the 1900 Summer Olympics in Paris, France. It disappeared until 1912, but has appeared at every Summer Olympic Games since. The current Olympic equestrian disciplines are Dressage, Eventing, and Jumping. In each discipline, both individual and team medals are awarded. Women and men compete together on equal terms. - The 1932 Summer Olympics, officially known as the Games of the X Olympiad, was a major worldwide multi-athletic event which was celebrated in 1932 in Los Angeles, California, United States. No other cities made a bid to host these Olympics. Held during the worldwide Great Depression, many nations and athletes were unable to pay for the trip to Los Angeles. Fewer than half the participants of the 1928 Summer Olympics in Amsterdam returned to compete in 1932. Even U.S. President Herbert Hoover skipped the event. - Herbert Clark Hoover (August 10, 1874 October 20, 1964) was an American politician who served as the 31st President of the United States from 1929 to 1933. A Republican, as Secretary of Commerce in the 1920s he introduced Progressive Era themes of efficiency in the business community and provided government support for standardization, efficiency and international trade. As president from 1929 to 1933, his ambitious programs were overwhelmed by the Great Depression, which seemed to get worse every year despite the increasingly large-scale interventions he made in the economy. He was defeated in a landslide in 1932 by Democrat Franklin D. Roosevelt, and spent the rest of his life as a conservative denouncing big government, liberalism and federal intervention in economic affairs, as Democrats repeatedly used his Depression record to attack conservatism and justify more regulation of the economy. - Count (male) or countess (female) is a title in European countries for a noble of varying status, but historically deemed to convey an approximate rank intermediate between the highest and lowest titles of nobility. The word "count" came into English from the French "comte", itself from Latin "comes"in its accusative "comitem"meaning companion, and later companion of the emperor, delegate of the emperor. The adjective form of the word is "". The British and Irish equivalent is an earl (whose wife is a "countess", for lack of an English term). Alternative names for the "count" rank in the nobility structure are used in other countries, such as "Graf" in Germany and "Hakushaku" during the Japanese Imperial era.
