fischeri, whereas it inhibited pathogen Pseudomonas aeruginosa. Also, the slow-release was shown to be far more effective than by applying the chemical directly as an aqueous solution. Since quorum sensing is also important for pathogen establishment this application could be important for inhibiting pathogenic bacteria from colonization of internal medical devices. In summary, the V. fischeri and squid symbiotic relationship is an important model host-bacteria system. Aspects of colonization of host-symbiont and host-pathogen have been shown, using the V. fisheri and squid model, to be the same. Therefore, understanding the mechanism and complex transcriptional regulatory systems of V. fischeri could lead to potential new therapies and pharmaceutical applications. Likewise, understanding the environmental factors necessary for successful host-bacteria interactions could lead to novel drug targets. In addition to being important in understanding other harmful host-bacteria relationships the V. fischeri and squid model is important in understanding population ecology. Since V. fischeri must adapt to and successfully live in both aquatic environments and within the squid light organ they must be highly adaptable to change. Somehow both V. fischeri and their host squids are able to balance strict specificity with enough flexibility to allow adaptation. Understanding this ability to adapt and change to widely varying, or rapidly changing environments could be very important in the future. One of the challenges presented by global warming is the potential extinction of species that are not able to adapt. The study of the V. fischeri and squid model offers us a chance to determine how quickly organisms can adapt to change and also whether https://www.paperdue.com/essay/luminous-bacterium-vibrio-fischeri-vibrio-6742
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
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
What are Bacteria and Viruses? The most palpable variance between bacteria and viruses is their size. Whereas both bacteria and viruses are too tiny to notice with the naked eye, most bacteria are about one micrometer in length and can be perceived with a good optical microscope. On the other hand, viruses are smaller than the wavelength of visible light, which implies that they can be solely perceived by using an
Bacteria Effect of date extract on different types of bacteria Taxonomy of date Kingdom: Plantae Division: Magnoliophyta Liliopsida Order: Arecales Family: Arecaceae Genus: Phoenix Species: Phoenix dactylifera Binomial mane: Phoenix dactylifera Linn (Bostoen 2005) 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
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
