acterial carbon to protistan grazers, and a 7% decrease in macrozooplankton production" (7). Hence, marine viral activity moves more respiration and production away from the other heterotrophs and into the bacteria. Marine viruses also have an impact on the diversity observed in the bacterial community and the composition of the species in the ocean as they usually are highly specific for certain hosts. The impact of viruses on ocean biogeochemistry is often evoked purely through the act of…

inhibiting bacteria. This result however, does not signify that natural remedies are inadequate at inhibiting bacteria. It reflects that natural remedies are ineffective in inhibiting gram-positive bacteria. First natural product: Saliva for instance, is one of the body’s many defence mechanisms. Its main function is to prevent adhesion of bacteria to oral surfaces. This means that saliva does not specialise in killing bacteria. Research has indicated that saliva have anti-bacteria property…

The growth of bacteria is very important to human life and plants as well as many more things. So, the question arises" how does bacteria grow and function" as well as "how does bacteria effect the environment" and many more, but in this paper, I will be explaining the simply needs of bacteria as well as where is can live and where is cannot. As well I will be talking about how curry and cinnamon affect bacteria. The first thing is what is bacteria. So, bacteria are good in many was as it is…

Bacteria A person with a cold can spread the infection by coughing and/or sneezing. Bacteria or viruses can be passed on by touching or shaking hands with another person. Touching food with dirty hands will also allow viruses or bacteria from the intestine to spread. Water bacteria needs water to dissolve the food they use for energy and growth. Energy sources such as sugars, starch, protein, fats and other compounds provide the nutrients. Oxygen some bacteria require oxygen to grow (anaerobes)…

antibiotic you rely on for your health. Sadly this is becoming a reality for many individuals. Simple infections are becoming harder to treat due to antibiotic resistance. Antibiotic resistance has caused a major health issue around the world. As bacteria continues to adapt, it has become more difficult for antibiotics to properly treat infections. Antibiotics are prescription medications that help fight against bacterial infections. Higher levels of antibiotic resistance are transpiring due to…

Both archaea and bacteria share the following similarities, they are both prokaryotes, without any complex cell structure. When looking through a microscope they are both identical in appearance to include shape and size. They both reproduce using binary fission, and move around using flagella. Archaea and bacteria have cell walls on the outside, which provide support, and lets Archaea and bacteria are both prokaryotes, meaning they do not have a nucleus and lack membrane-bound organelles.…

Title: Which Antibiotics Kill the Most Bacteria? Caroline Gorman April 2, 2016 HB bl. 6 Purpose: The purpose of this lab was to determine which of five common antibiotics would kill the Rhodococcus rhodochrous bacteria. Hypothesis: Out of the five tested antibiotics, doxycycline will kill the most Rhodococcus rhodochrous because it is generally used to treat mild infections. This will be tested by spreading the bacteria on agar in a Petri dish and adding a small amount of each antibiotic…

• Bacteria, are single-cell microorganism with no nucleus that had a sphere, rod, and spiral shape and branching threads. Ranges in diameter between (0.5- 1) µm and in length between (2-4) µm however, they are either a parasite or live independently they are found in all living things and in all environments. Some bacteria in drinking water can cause disease such as salmonella, total coliform (including fecal coliform and E.coli), Shigella, Legionella, and Campylobacter and “their presence…

5.3 Responses to probiotic bacteria and microbiota Pathogenic bacteria are not the only bacteria that elicit immune responses in the intestine as probiotic bacteria have also been tested as a food supplement to improve fish health. Few studies have evaluated the impact and regulation of Igs after probiotic administration. Most of these studies showed an increase in IgM secretion and/or expression after probiotic administration (Picchietti et al., 2007; Sun et al., 2010). However, a…

Discuss antibiotic resistant bacteria, cause and effect. Antibiotic resistant bacteria is a big concern now a day due to the use of excessive and improper use of antibiotics. It is very common for people to star taking an antibiotic and stop the regimen as soon as the symptoms are gone. With this practice, bacteria that were not killed by the antibiotic but were exposed, are capable of becoming immune to it. This immunity or resistance can be passed on from bacteria to bacteria through the…
