Bacterial Biology █ BRIAN D. HOYLE An understanding of the fundamentals of bacterial biology is critical to bacteriologists and other forensic investigators attempting to identify potential biogenic pathogens that may be exploited as agents in biological warfare or by bioterrorists. Fundamentals of Bacterial Biology Bacteria are one-celled prokaryotic organisms that lack a true nucleus (i.e.‚ a nucleus defined by a membrane). Bacteria maintain their genetic material‚ deoxyribonucleic

Since then «the earth is a fundamentally a microbial planet‚ to which the micro-organisms are recent the relatively unimportant additions» (Wheelis‚ Mark‚ Principles of modern microbiology‚ 2008‚ p.1). The term microorganisms consist of bacteria‚ archaea‚ fungi‚ and protest‚ which can either be unicellular or multicellular. They first have been studied by Anton van Leeuwenhoek by the use of his own design microscope‚ in 1675. However‚ they have been an attractive source of study for many scientists

Extremophiles Extremophile: a word combination of the Latin extremus (extreme) and Greek philiā (love). Contrary to the average human‚ extremophiles love the extreme‚ preferring seemingly uninhabitable environments to resource rich habitats. These archaea are the toughest out there‚ and are found thriving in deep-sea thermal vents and sub-glacial lakes. A few of the outlandish environmental niches extremophiles have adapted to are high/low temperatures‚ pH extremes‚ the absence and excess of oxygen

Leading Disease Killer in the World Microbes orbit the world that is around us involving being in the air and on surfaces we may come in close contact with. In the medical terms‚ microbiology involves the study of microscopic organisms‚ bacteria‚ archaea‚ fungi‚ protozoa‚ algae‚ and multi cellular animal parasites (Baumann 3-5). It is important that we acquire knowledge of these subjects because there are many infectious diseases that can directly and indirectly affect our immediate environment and

According to Ursell & Metcalf (2012)‚ the microbiome is recognised as a body’s microbial makeup. It has been observed that the distinctive makeup of virtuous and bad microorganisms create the whole body‚ comprising the digestive system. In addition to this‚ the microbiome has brought into being within the digestive system such as the stomach as well as the intestines‚ however‚ it is likewise discovered within the mouth‚ oesophagus as well as in the skin.

Meiosis was discovered and described for the first time in sea urchin eggs in 1876 by the German biologist Oscar Hertwig. It was described again in 1883‚ at the level of chromosomes‚ by the Belgian zoologist Edouard Van Beneden‚ in Ascaris worms’ eggs. The significance of meiosis for reproduction and inheritance‚ however‚ was described only in 1890 by German biologist August Weismann‚ who noted that two cell divisions were necessary to transform one diploid cell into four haploid cells if the number
