BACTERIA
Pseudomonas Bacteria
This study concerns the Pseudomonas type bacterium strains that have, in recent years, become more of a concern for medical professionals. The primary issue is that several different types of the bacteria, especially pseudomonas aeruginosa, have been shown to have a resistance to many common antibiotics. Another issue with this genus is that it is a very common type of bacteria that naturally occurs in the soil, in plant matter and on humans. Therefore, it has been widely studied, and the dangers of pseudomonas infection have been widely documented.
Using different imaging techniques the infection from pseudomonas aerignosa has been shown in different types of pneumonia, cystic fibrosis, endocarditis, and bone and joint infections. The damage done to different types of tissue shows up on scans as fibrosis, lesions, erosions and other evident deteriorations. The issue is both that this common bacterium can cause significant cellular damage and that it…...
Bacteria?
Many people believe that bacteria only cause disease and death. This is not technically true. While we have all suffered from some kind of an infection which we are told is caused some noxious form of bacteria, this is just a small part of what bacteria contribute to out lives.
First, it would be well to add a bit of science to be clear about what bacteria are. Defined most correctly, bacteria are a large group of one-celled microorganisms widely distributed in nature. Search any microbiological text book and you will see that there are thousands of different types of bacteria in the world, everywhere around us, although only about two thousand species of bacteria have actually been identified. On the most part, bacteria simply share the world with us and are of no specific harm to any human being. They are remarkable organisms for their simplicity of form, their…...

Botanical Descriptions
The date palm is known in technical terms by its botanical name Phoenix dactylifera. The properties and the composition of the date extract have been noted to have many beneficial effects in medicine as well as domestically. The following paper intends to shed light on the impact of date extracts on the different types of bacteria.
The date palm is botanically dioeciously in nature. It is a medium sized plant that has pinnate leaves and it has approximately 140 to 145 leaflets and these leaflets bears the spines by the petiole. The small yellow colored followers of the date palm are found attached directly to the spikelets that later develops to form the juicy and nutritious dates. The dates are cylindrical in shape and have a single seed…...

One organism, Methicillin-resistant Staphylococcus aureus (MRSA), kills approximately 19,000 Americans annually, which is more than HIV / AIDS, Parkinson's disease, emphysema, and homicide combined (5). In the mid-1980s, the incidence of MRSA isolates was close to zero, and by 1998 the incidence of MRSA was approximately 70% in Japan, 40% in Belgium, 30% in the United Kingdom, and 28% in the United States (1). Every year, 2 million Americans obtain hospital-acquired infections, most of which are caused by antibiotic resistant microorganisms, and result in 99,000 deaths (5). In malaria-endemic countries, resistance to earlier anti-malaria medications such as chloroquine and sulfadoxine-pyrimethamine is widespread, which sustains malaria as a significant health threat (2). Antibiotic resistance is relevant in every country, and has the potential to affect all strands of bacteria that are responsible for human infection.

The work of McGeer and Fleming (2012) relates that the evolution of resistance in common hospital pathogens in Ontario has been tracked by QMP-LS since 1996. The 16th annual survey was conducted by QMP-LS in January 2012, which assessed the incidence of resistant hospital pathogens in the province in 2011. All 77 currently licensed bacteriology laboratories are reported to have responded. These laboratories provide services for 211 hospitals. It is reported that resistance in Pseudomonas aeruginosa in 2011 identified "7310/40-110 (18.2%) isolates resistant to ciprofloxacin and 3388/39308 (8.6%) resistant to imipenem/meropenem both of which have increased (from 17.7% and 8.1%, respectively) compared to 2010.Twelve laboratories reporting 9797 isolates of P. aeruginosa were not able to provide data for the number of isolates that were resistant to all agents tested."

Gram Stain
Bacteria Identification
Following standard procedure for Gram staining, a slide was prepared by heat fixing the sample and applying the primary crystal violet stain (Bruckner, 2012). After incubation in the primary stain for a period of one minute, the stain was rinsed under a slow stream of water for four seconds before fixing the remaining dye with Gram's iodine, with immersion in this mordant lasting one minute (Bruckner, 2012). Following this, a second rinse using acetone, again poured in a very slow stream and this time lasting for less than three seconds, removed any non-fixed crystal violet and left behind only the dye fixed within the Gram-positive bacteria of the sample (Carleton, 2012). Safranin was added as a secondary stain and incubation again lasted one minute, with a rinse of four seconds under a slow stream of water occurring before examination of the slide (Carleton, 2012). All observable bacteria were…...

The virus genome covered by the capsid penetrates the host cell. Once inside, the virus is uncoated as the envelope and capsid are removed. Free of its covering, the viral genome (DNA or RNA) proceeds with biosynthesis. Newly assembled viral particles are released by budding. Components of viral envelopes (i.e., lipids, proteins, and carbohydrates) are obtained from the plasma or nuclear membrane as the viruses leave the cell. Budding does not necessarily kill the host cell.
A retrovirus is a virus which has a genome consisting of two plus sense RNA molecules, which may or may not be identical. It relies on reverse transcriptase to perform the reverse transcription of its genome from RNA into DNA, which can then be integrated into the host's genome with an integrase. The virus itself is a storage form for its nucleic acid genome as well as a means of delivery of its genome…...
Salmonella
Fig 1. Salmonella Bacteria
The first thing to note about Salmonella (seen in Fig. 1) is that it is a bacteria, and therefore a living organism. However the term "Salmonella" is used loosely in daily conversation to specify an illness caused by that bacteria in humans, and in other animals. Most people have some vague recollection of a "salmonella outbreak" caused by a contaminated food supply being reported in the media, and some people may have contracted Salmonellosis, which is technically the name of the human disease. Salmonella is just the organism that causes it. But because Salmonella is a form of life it needs to be understood environmentally, and so I would propose addressing it on each individual environmental level, as specified in this concept map:

Helicobacter pylori is a gram-negative germ (bacterium) that typically infects the stomach or duodenum, but can also be found in other parts of the body. This bacterium is very common and it is believed that approximately half of the planet's population has it. Individuals in developing countries are predisposed to it as a consequence of poor sanitary conditions in these areas. The bacteria can typically be found in the inner lining of the stomach and it can lead to conditions like gastritis, ulcer, or even cancer. There are a series of variables that can influence the disease most likely to affect a person, with his or her background playing an important role in the bacteria's development.
People are most commonly infected as a result of eating or drinking foods or liquids that are contaminated. One is also likely to contract the bacteria if he or she interacts with another individual having…...

microorganism, Bradyrhizobium japonicum, displays a symbiotic relationship with soybean plants. There are different factors that may affect the relationship of this microorganism with plant biomass. These factors may be pH, temperature, the nutrition status and density of soil. The aim of this study was to determine the effects of different soil treatments, in different soil types, on nodule formation and the dry weight of the plant. For this purpose, soil samples were collected from three locations, namely, at a forest, near a stream and potted soil. Each sample was then analyzed with a hydrometer and classified to a soil type. The forest soil was of clay loam type, the pot soil was loam soil and the stream sample was loamy sand. The samples were subjected to different treatments, such as sterilization and inoculation. The dry weight and number of nodules on each soil type was measured. esults showed that…...

Bacterial Effects on the Body
Some bacteria produce a toxin that causes a flaccid paralysis, while other bacteria produce a toxin that causes all of the skeletal muscles to contract at the same time. In understanding these effects that such bacteria can have on the human body, one can begin to fully understand the root causes of these bacterial toxins as well as the full extent to which these toxins can cause damage. Additionally, in beginning to understand the processes and complexities of each bacterial effect on the body, one can begin to understand the processes used by the body to repair areas that are damaged, such as the peripheral neuron.
As mentioned, some bacteria produce a toxin that causes flaccid paralysis while others produce a toxin that causes all of the skeletal muscles to contract at the same time. In noting these facts, one can begin to ask the question of…...

Categories of Antimicrobial Agents
Differentiating between viruses and bacterial infections is absolutely critical to give a patient adequate treatment. Antibiotics such as penicillin and its derivatives will not work on a viral infection. Not only are antibiotics ineffective against viruses; they are actually harmful given that overuse of antibiotics can give rise to antibiotic-resistant infections, both in the patient and in society as a whole. Primary care providers are on the front lines of fighting over-prescription of antibiotics and ensuring that antibiotics are prescribed solely for conditions for which they are effective and necessary.
"Bacteria are single-celled microorganisms that thrive in many different types of environments" (Steckelberg 2015). While many kinds of bacteria are harmless, some can be very dangerous, such as the bacteria that cause strep throat, tuberculosis, and urinary tract infections (Steckelberg 2015). In contrast, "when a virus enters your body, it invades some of your cells and takes over…...

Introduction
In recent years, the use of face masks has become increasingly common, especially in light of the global COVID-19 pandemic. While face masks are essential for preventing the spread of viruses and bacteria, their prolonged use can also contribute to the accumulation of microbes on the mask's surface. This has raised concerns about the potential bacterial contamination of face masks and the associated health risks.
Studies have shown that bacteria can easily transfer from the wearer's skin to the mask's surface through respiratory droplets, sweat, and other secretions. As a result, the continued use of face masks without proper cleaning and disinfection can lead to the growth and proliferation of various types of bacteria. These bacteria can then pose a risk of infection to the wearer if inhaled or come into contact with the skin.
Identifying the types of bacteria present on the surface of face masks is crucial in understanding the…...

Environmental Hazards
hat are toxicants and how do they affect living organisms?
According to Dr. Celine Godard, toxicants and toxins both reference substances that are toxic; however, toxins are made in nature (like in poisonous mushrooms or in the poisonous venom that snakes use to kill their prey) and toxicants are human made (Godard, et al., 2001). Examples of toxicants would be "industrial waste products and pesticides" -- along with pollutants that get into the oceans. In fact pesticide residues (toxicants) are found in the ocean, and Godard's article in the Public Broadcast Service (PBS) is about how the Ocean Alliance is researching the impacts that toxicants have on sperm whales.
Sperm whales are exposed to the pollution (toxicants) that humans allow to flow into the oceans, and the whales have a "layer of fat called blubber" beneath their skins; Godard explains that toxicants accumulate in fatty tissue and so the longer the…...

healthy individual is infected with a bacteria or virus, the body identifies the virus as an invader, and therefore produces the antibodies, which is the human body's immune system, to destroy the virus to assist the person to recover and become healthy. Meanwhile, vaccination is the process of stimulating the active immune system to fight disease in the body, and vaccine will boost the body active immunity to fight disease that may come into the body in the future. Through immunization, a child body system will enhance immunity in such a way that when he is in contact with a disease, his immune system will identify the disease as an invader and will produce the antibodies to fight the disease. In essence, active immunity is life-long lasting.

To write an essay on the impact of contagious diseases, you will want to narrow down the topic. There are several different types of contagious diseases, and the various pathogens include viruses, bacteria, fungi, and protozoa. Disease can spread in various ways. The current Covid-19 pandemic is airborne and spreads through both air and touch, but other diseases have been blood borne, sexually transmitted, spread in food, or spread through other vectors, such as mosquitoes. There are also different types of outbreaks of diseases including pandemic, endemic, epidemic, and outbreak. They have....

Much has been made of the possible relationship between obesity and gut bacteria. Rather than the simplistic view of obesity that once posited that obesity was always simply a matter of consuming too many calories or being too sedentary, modern research has revealed that a number of factors contribute to obesity. This has helped lead to epidemic levels of obesity, which has a domino effect on other health issues. Determining which factors help influence obesity is one of the keys to fighting this epidemic. Gut bacteria is one of these factors.
