(2 points) Discuss the arguments for and against the classification of viruses as living organisms. For: viruses are classified as living organisms due to their possession of DNA or RNA in their systems. DNA and RNA are essential components of any living organism.…
A total of four microorganisms were isolated from the sample brought back from Mars. To identify the microorganisms which were isolated from the sample brought back from Mars, an rDNA sequence analysis was required. Every sequence had an S_ab score of 1.000 meaning the sequence is identical to the microorganism that it was matched to. Before gathering phenotypic results, we gathered phylogenetic data for the four microorganisms which includes Micrococcus luteus, Citrobacter freundii, Hafnia alvei, and Staphylococcus epidermidis. Micrococcus luteus is a gram positive, coccus shaped microorganism that is nonmotile and unable to grow on glucose minimal media or simmons citrate agar (Kocur, 1972;).…
Abstract Smallpox is a highly infectious disease caused by the Variola virus. This report explores the taxonomic classification, “life cycle”, and mechanism of replication of this pathogen, as well as discusses the virulence and treatment options for an infected human host. This member of the Orthopoxvirus genus is extremely virulent, and has a fatality rate of nearly 30%. While this virus only attacks a human host, similar members of the Voxviridae family produce similar infections in animals.…
However, when left alone they can’t reproduce. Only when they infect other organisms can they make more of their own kind. Should viruses be considered living? Why or why not?…
The definition of a virus from the Oxford Dictionary is, an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host: To me that means that they are these tiny molecules that are not cells, but able to multiply, but only inside of the cells of the person the virus has gone into. Viruses are not living things. They do have many things inside them that a living thing may have like proteins, nucleic acids, carbohydrates and Lipids. the problem is that they can't function…
Viruses “rely on their hosts to carry them around and introduce them to new hosts” (Survival of the Sickest, paperback, p. 119). The cold virus knows that its host has to be relatively healthy so its ride can be mobile (Survival of the Sickest, paperback, p.119). The virus has evolved with humans to allow it to reproduce faster and survive more efficiently. If you take the host out of the picture, the cold virus could never survive or reproduce. The rabies virus is another manipulative virus.…
Viruses have a mind of their own, and in the years to come who knows how they will have mutated and developed. What seems like a runny nose or just the flu could develop into an immune system attacker that can kill its host in days. As society gains more information about the unknown in viruses, the more it strikes fear in their lives. It causes society to act irrationally and lock up who ever they can find to make themselves feel safe. When it comes to diseases that can kill people will break constitutional and human rights to gain a false sense of peace.…
A is also responsible for many flu epidemics. This strain’s viruses is so strong, it can even infect animals. Wild birds often act as hosts to spread this strain, but you can even catch it from your pet. This strain is also spread through contact with surfaces touched by an infected person. B, on the other hand, can only infect humans.…
Introduction Identifying unknown bacterium is not only vital to microbiology, but also to the medical and pharmaceutical industries in order to treat disease/infection properly. Bacteria are classified and identified to distinguish among strains and to group them by criteria of interest (1). There are several different procedures that can be utilized to identify a bacterium. This includes the oxidation test, gram stain, and catalase test. The purpose of this lab report is to show the understanding of all procedures used to identify the bacterium, and explain how the given results led to the identification of the unknown bacterium.…
The bacteria used in the experiment are Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, Klebsiella pneumoniae, and Salmonella pneumonia. These all bacteria will be culture in the nutrient broth. The first stage is making Nutrient Broth. Weigh out 5.8 grams of nutrient broth powder.…
E.Coli (Escherichia Coli ) Brenda Arambula Health Science Technology 3/4/2016 INTRODUCTION Escherichia Coli most known as (E.Coli) is a bacteria that normally gets into your intestine of humans and sometimes even warm blooded animals .Some of the E.Coli are even capable of causing diseases with conditions that can harm your immune system . E. Coli can make everyone sick but it mostly affects young children and elderly people this people are mostly likely to…
Both of these viruses have proven over time that they are not to be fooled around with, and often times have sent strong nations scrambling for survival. In Emily St. John Mandel’s science fiction novel Station Eleven, she shows us what life could be like if our population was to be swept away by disease. In this story, a highly lethal…
Introduction: The name Pseudomonas is derived from the greek and latin words which means “false unit“ (pseudo = false, greek; monas = single unit, latin). “Monas” was used in the early history of microbiology to define single-celled organisms. In 1786 Otto Friedrich Müller, from Copenhagen, classified the bacteria and named the pseudomonads, they came into the group of vibriones (which was defined as group of shaking bacteria). Many years later it was detected that Pseudomonas are motile.…
A virus is a non-living infectious agent that is too small to be seen by regular light…
There are two different types of bacteria in the body, the good bacteria and the bad. The healthy and good bacteria in the body is often killed along with the bad bacteria which can lead to more problems in the body. Antibiotics are used to destroy the cell walls in bacteria. When antibiotics are prescribed for viruses not only do they not help cure the virus, because there are no bacteria cells for it to kill, but it destroys the healthy bacteria, causing more problems for the body.…
