Salmonella Enterica
There is a lot to know about this bacterium. There are over 2,500 different serotypes of Salmonella Enterica, for example serotype Typhimurium (Pg, 355) (Pommerville, 2011). Salmonella Enterica can cause many different infections like salmonellosis, typhoid fever, and gastroenteritis. Because of carelessness in personal hygiene, this kind of infection can turn into an outbreak very easily. (CDC, n.d.)
Salmonella is still a very common source of foodborne illness! As of January 14th 2014 there was a reported outbreak of Salmonella Enterica Heidelberg involving Tyson mechanically separated chicken, which has (so far) infected 9 individuals (CDC, n.d.). What is Salmonella Enterica, and how do we prevent it from spreading? Research mechanisms, virulence, prevention and treatment are all very important aspects of a bacterial infection and each topic will be thoroughly discussed in the text below.
Methods for Studying Salmonella Microscopy. Microscopy methods of studying bacterial infections include using light and electron microscopes. Light microscopy methods utilized include; conventional phase-contrast, fluorescence, and confocal microscopy. Electron microscopes create higher quality images; for example, they have been used for studying the structure of T3SS in salmonella. However, light microscopes are used more regularly than electron microscopes because they are more widely available. They are used to study the relations, and interactions, between cells in the body and bacteria. (Springer, 2007) Environmental testing. Clean and sanitized swabs or sponges are used to sample surfaces that may be contaminated with salmonella. They are then put into an equally sanitized baggy that contains dey-engley broth. The sample is kept chilled until it is finally used for testing. When the swab or sponge is ready to be tested it is added to a jar with a lactose
