Archaea

The Genus Bordetella Bordetella are catalase positive, asaccharolytic, aerobic, gram positive rods, whose optimal growth is at 35° to 37°C. Disease 1. Species of Bordetella is known to cause respiratory diseases like whooping cough, pneumonia, and sinusitis. 2. There are eight species of Bordetella that cause different diseases including Bordetella parapertussis, Bordetella bronchiseptica, Bordetella avium, Bordetella hinzii, Bordetella holmessi, Bordetella trematum, Bordetella pertussis,…

Unknown Bacteria 228 Adisney Pino Professor Dowding Miami Dade College Section T/R 7:05PM Introduction Enterobacter aerogenes is rod-shaped bacteria that belongs in the family of Enterobacteriaceae. This rod-shaped bacterium is gram negative which makes it a facultative anaerobe which grew perfectly in 37-degree temperature. This species was motile and therefore it can synthesize an enzyme known as ornithine decarboxylase. This bacterium is prevalent in the intestines of animals…

General Unknowns Bacterium Vitality en Vida Bacteria play a vital role in our daily lives. It is therefore our right to know the importance of being able to distinguish certain strains of bacteria. With the right knowledge we would be able to come up with a cure for a disease. An identity gives way to knowledge, to better understanding and access to information on how an organism works and how we can prevent its worsening effects or isolate its benefits. Scientists have been trying to…

There are certain animals, plants, fungi, bacteria, and viruses that tolerate and actually thrive in extreme conditions. These organisms are called extremophiles. The word extremophile breaks up into “extreme” and the suffix “phile” literally means “one who loves.” These organisms flourish in the uninhabitable places that vary from extremely high and low temperatures, high pressures, high salinity, the absence of water, and extreme amounts of radiation just to name a few. Many of these…

The Microbial World on Your Teeth Have you ever realized just how important your teeth are? Smile. Whether you know it or not, your smile is a huge part of who you are.

This is just one reason why taking good care of our teeth is so vital. Have you ever wondered why you need to brush your teeth so often? Most people know that they are supposed to…

The development of advanced microscopes has enabled scientists to further their investigation on the criteria for life. As a result, biologists have been confronted with a baffling question: is there a size limit on life? If so, then just how small can something be before it can no longer be considered alive? Ever since the discovery of nano-sized particles called “nanobacteria” or “nanobes”, researchers have been scrambling to unravel and analyze the mysterious functions of these purported…

Deinococcus radiodurans was discovered in 1956 by scientists accidently, after a can of corned beef had been treated with radiation in order to kill any harmful microorganisms that might have been present in the canned meat. Since its accidental discovery, D. radiodurans has been intriguing scientists with is astonishing resistance to ionizing radiation, UV radiation, electrophilic mutagens, oxidizing agents, and desiccation. This gram-positive bacteria usually forms in spherical pairs or…

Jaqueline Moreira Biology 23 March 8, 2016 Pseudomonas aeruginosa Introduction P. aeruginosa belongs to the family called Pseudomonadaceau ( Willey, J., Prescott Microbiology, 2014, p.527). P. aeruginosa is a gram negative bacterium. The shape of this particular bacterium is straight or slightly curved rods, but not helical. The size of this bacterium is about 0.5-1.0 micrometers wide and 1.5-5.0 micrometers long. The arrangement is single, but as is starts to age it forms cysts. P.…

EA & JB 2 Identifying Neisseria sicca INTRODUCTION Bacteria are microorganisms constituting a large domain of prokaryote. They are typically a few micrometers in length and have a number of shapes ranging from spirals to rods and spheres. Bacteria are known to be among the first forms of life to appear on Earth, and are present in almost all habitats. They inhabit water, soil, radioactive waste, acidic hot springs, and Earth’s crust…

[ Classification ] Sept. 26th Introduction: Classification systems provide a logical way to organize and name living organism, based on the fact that some organisms resemble one another while others do not. There are currently two classification systems of organisms, into 5 kingdoms or 3 domains, both are distinguished by specific characteristics. Kingdom Monera have no well defined internals as they lack membrane to bound organelles, and Protists are single celled organisms that may be plant…
