Anaerobic respiration in Bacteria Like humans and other animals‚ bacteria need to breathe. Anaerobic bacteria basically mean bacteria that respire anaerobically. All living cells need to respire in order to release energy for vital cell activities. Anaerobic respiration is respiration in the absence of oxygen‚ hence anaerobic bacteria does not breathe at all. The purpose of respiration is to provide the cell with the appropriate molecules for creating energy in the form of adenosine triphosphate

Flesh-eating bacteria strikes in Florida On June 16th‚ 26 year-old Cason Yeager went for a swim in Florida in Hernando County and later died from contracting the flesh-eating bacteria‚ Vibrio Vulnificus. This bacteria can be found worldwide‚ most particularly in the warm coastal regions but there have been reports in other parts of the world in non-warm waters. According to the CDC in 2013‚ the case count of the vibrio vulnificus was 104 in thirteen states with six hospitalizations. No deaths‚ but

Sarah Burns Evolution of Plague Bacteria The Bubonic Plague otherwise known as the Black Death‚ has gotten most of its attention from medieval paintings‚ poetry‚ and journals of revulsion. The real horror‚ was the disturbing biological evidence of the bacteria that caused all the pandemics‚ known as Yersinia pestis. The pathogen got its name from the two investigators Yersin and Kitasato. In 1894‚ Yersin was known as the main investigator (ergo. Named after him)‚ he claimed that the mice/rats were

difference between bacteria‚ viruses‚ fungi and parasites are: Bacteria are single celled organisms that can rapidly multiple themselves every 10 minutes up to 10 times each bacterial cell‚ but they do not live or reproduce in a human cell. When threatened they will make a copy of their DNA to enable them to come back to life in the right conditions. They are able to survive in most extreme living conditions including with and without oxygen‚ there are various types of bacteria such as Cocci/Coccus

Kenny Vo Microbiology Dr. Arora 10 December 2012 Flesh Eating Bacteria Necrotizing Fasciitis is a rare bacterial disease that causes the rapid decay of the fascia. The human body is said to be compose of approximately a hundred trillion cells‚ connective tissue contributes to about forty five percent of the total cell weight. It was nicknamed the flesh eating bacteria because the victims injuries would have a rotting appearance. What are the pathogens that cause this disease? Necrotizing

Bacteria are often maligned as the causes of human and animal disease (like this one‚ Leptospira‚ which causes serious disease in livestock). However‚ certain bacteria‚ the actinomycetes‚ produce antibiotics such as streptomycin and nocardicin; others live symbiotically in the guts of animals (including humans) or elsewhere in their bodies‚ or on the roots of certain plants‚ converting nitrogen into a usable form. Bacteria put the tang in yogurt and the sour in sourdough bread; bacteria help to break

Microbiology‚ 2002. vol.3. Temperature and bacteria The lowest temperature at which a particular species will grow is the minimum growth temperature‚ while the maximum growth temperature is the highest temperature at which they will grow. The temperature at which their growth is optimal is called the optimum growth temperature. In general‚ the maximum and minimum growth temperatures of any particular type of bacteria are about 30°F (-1°C) apart. Most bacteria thrive at temperatures at or around that

Antibiotic Resistant Bacteria A better understanding of the use of antibiotics would help prevent the reality of antibiotic resistant bacteria evolving to the point of human extinction. Antibiotic resistance is a natural process‚ stronger bacteria survive and multiply. Even though antibiotic resistance is a natural process‚ it happens faster when antibiotics are used irresponsibly. Through use of media‚ personal responsibility and research‚ our species could help deter further antibiotic resistance

· Taxonomy ○ Science of classification ○ Provides an orderly basis for the naming of organisms and for placing organisms into a category (taxon) ○ Makes use of and makes sense of the fundamental concepts of unity and diversity among living things ○ Basic principle is that members of higher-levels groups share fewer characteristics than those in lower-level groups * Escherichia coli - rod shape and have a Gram-negative cell wall * Even members of the same species display variations

Effectiveness on Gram Positive and Gram Negative Bacteria. INTRODUCTION: Bacteria are microbial organisms which are present in various environments. Many bacteria are good and help humans synthesize materials and assist in biological processes‚ such as digestion. However‚ some bacteria can cause harmful diseases. When harmful bacteria infects the body‚ people take antibiotics in order to suppress bacteria. Different antibiotics have different ways they suppress bacteria‚ and the efficacy of antibiotics depends
