Bacteriophages

P. aeruginosa is a gram-negative non-sporulating bacillus that belongs to the phylum of Proteobacteria. It can adapt and thrive in different niches, ranging from water/soil to plant/animal tissues. Even though it is commonly found in the environment, it frequently causes infections in plants and animals (1). Luke (1862) was the first to report P. aeruginosa in infections as he observed rod-shaped particles in blue-green pus of some infections. This coloration is a hallmark of P.…

Solution for Antibiotic Resistance So knowing the history about the discovery of antibiotics and what was the main purpose of this drug will put your mind at ease. Like I stated earlier, our society take antibiotics for any reason. One of the best solution is to take a broader view of the microbes. Microbes which are single-cell organisms so tiny that millions can fit into the eye of a needle. They are the oldest form of life on earth. Microbe is a term for tiny creatures that…

Trend #1: Lateral Flow Immunoassay (LFI) Shan, S., Lai, W., Xiong, Y., Wei, H., and Xu, H. (2015) Novel Strategies To Enhance Lateral Flow Immunoassay Sensitivity for Detecting Foodborne Pathogens. Journal of Agricultural and Food Chemistry. 63, 745−753. DOI: 10.1021/jf5046415. This article talks about the simplicity, stability and sensitivity of conventional lateral flow immunoassay (LFI) device for the use of detecting foodborne pathogens. Foodborne pathogen has prevailed to cause disease…

conclude that it was strictly DNA being transferred not proteins, which many scientists thought proteins created life. In their experiment, they used bacteriophages, which is a virus that infects a bacterium. They used sulfur, which is found in proteins to see what color the bacteriophages would reproduce. As for the phosphorus labeled bacteriophages which is found in DNA in the other experiment. The experiment with Phosphorous proved DNA was the hereditary material. In the 50s scientists James…

surface. This is typically accomplished by the recognition of a receptor on the outside of the bacterial cell wall such as an antigen, pilus or other structure. There is much variability from phage to phage in terms of which receptor they bind to. Bacteriophage can generally be classified into two categories, lysogenic and lytic (virulent) (Fig 6). The choice between the lytic and lysogenic cycle depends on the relative expression rates of phage repressor encoded by a cII gene (promoting…

Bacteriophages are useful for many things, one being that they produce enzymes. One enzyme that they produce in particular is the lysine. Lysins are used majorly to digest the cell wall of bacteria. Bacteria have been increasingly gaining resistance to antibiotics and lysins have been used in animal models to control these specific bacteria. Scientists may need these lysins to stop bacteria from becoming more and more resistant to antibiotics. Bacteria is infected by bacteriophage when it…

Transduction is the process of how foreign DNA is transferred into a gene cell. An example is the viral transfer of DNA from one bacterium to another. After the gene cell's are multiplied the viruses assemble and remove a portion of the host cell's bacterial DNA. Transduction is one of the most common tool used by molecular biologist to introduce a foreign gene into a new host cell's genome. "Specialized Transduction".thefreedictionary.com N.p., 2017. Web. 12 May 2017. While the new tool,…

Laboratory Analysis Justyna Sudyka 1. a. Clostridium sporogenes grew throughout all of the thioglycollate broth, but there was more growth towards the bottom. The aerobic TSA + glucose plate did not have any growth, but the anaerobic plate did have growth. Escherichia coli grew throughout all of the thioglycollate broth as well, but the organism was clustered slightly more towards the top. There was growth in both aerobic and anaerobic TSA + glucose plates. Micrococcus luteus only grew at the…

Livestock production and climate change affect and get influenced by each other. The most important effects of climate change on the environment and livestock include rise in temperature, elevation in sea level, alteration in microbial eco-system and several others effects, known or unknown which might affect the livestock positively or negatively. There have been various predictions about the quantum of sea level rise with varying degree of confidence because many of the natural phenomena have…

With the well of new with antimicrobial compounds drying up, current research on slowing or side-stepping antibiotic resistance is exploring a myriad of possibilities. This paper will focus on methods such as membrane disruption, inhibition, and bacteriophages that are being used alone or together to target resistant…
