Currently‚ 800 million people suffer from the nutritional deficiencies‚ with 40‚000 dying each day of malnutrition‚ half of them children. There is much disagreement about the causes of such hunger. Some argue that food shortages arise from inequities in the distribution and that the dire poor simply cannot afford food. Others regard food shortages as evidence that the world is overpopulated that the human species has exceeded the carrying capacity of the planet. Whatever the social and demographic

However‚ in cases in which the persons with immunodeficiency‚ or a immune deficiency‚ an “effective cell-mediated immune response” may fail to occur and thus allow the disease to further progress and possibly spread from the lungs (“Tuberculosis”). A tuberculosis infection outside of the lungs is called extrapulmonary tuberculosis. In these instances‚ the kidney and bones are more commonly prone to infection. In the kidney‚ tuberculosis proposes little to no symptoms‚ but may destroy part of

Overall‚ one-third of the world’s population is currently infected with the TB bacillus. How TB Spreads: TB is a contagious disease. Like the common cold‚ it spreads through the air. A person acquires a tuberculosis infection by inhaling tiny droplets of moisture contaminated with the Mycobacterium Tuberculosis bacteria. The source

Microbiology Lab Quiz #2 Study Guide Exercise 9 -- The Gram Stain Compare and contrast simple and differential staining techniques. Simple Staining Simple staining is useful in determining the basic morphology of an organism. Simple staining involves only one reagent i.e. crystal violet‚ basic fuchsin‚ or methylene blue. Simple dyes used to stain bacteria have a positive charge cationic (+)‚ therefore‚ they are attracted to the bacteria that are usually negatively charged anionic (-) Depends

Clostridium Perfringens Clostridium perfringens (formerly known as C. welchii‚ or Bacillus welchii) is a Gram-positive‚ rod- shaped‚ anaerobic‚ spore-forming bacterium of the genus Clostridium. C. perfringens is ever present in nature and can be found as a normal component of decaying vegetation‚ marine sediment‚ the intestinal tract of humans and other vertebrates‚ insects‚ and soil. Infections due to C. perfringens show evidence of tissue necrosis‚ bacteremia‚ emphysematous cholecystitis
