Bacteria

Bacteria are found everywhere around us and many of which are beneficial to the environment and humans, assisting in protecting the biodiversity of ecosystems within an urbanized environment. This paper aims to determine the role and functions of bacteria found within the ponds of Centennial Park in relation with other bacteria and eukaryotes. This was achieved through the process of traditional and modern microbiological techniques of gram staining, biochemical tests and 16s rRNA analysis of bacterial

Vibrio bacteria are Gram-negative with straight or curved rods. These bacteria are motile and have one polar flagellum that has a sheath around it. They occur in both marine and fresh water habitats. There are different factors to include when trying to grow this bacteria. In order for the different species of the Vibrio genus to grow, they need to be in salt or sea-water based medium for optimal growth and can grow in temperatures varying from 10C to 37C. Vibrio bacteria are facultative anaerobes

and the delivery of different components via these vesicular structures are common among Gram-negative bacteria, especially during the infection. But there are few studies on EV formation in Gram-positive bacteria. It has become evident that MVs serve as transport vehicles containing different cargoes. Although there are some differences in cell structure of Gram-positive and Gram-negative bacteria, many

Streptococcus pneumoniae: Pneumococcal Pneumonia INTRODUCTION Streptococcus pneumoniae is a gram-positive bacteria that is a facultative anaerobe. This strain of bacteria can cause five different bacterial diseases. Streptococcus pneumoniae can cause pneumonia (an infection of the lungs), otitis media (an infection of the middle ear), sinus infections, bacteremia (an infection of the bloodstream), and meningitis (an infection of the covering around the brain and spinal cord). The most common disease

resistant bacteria in seafood are a major public health concern worldwide. Reports on use of antimicrobials in aquaculture and residue findings in the products have indicated food safety threat to the consumers. In aquaculture, the use of wide array antimicrobials leading to development of bacterial resistance, use of resistant probiotic resistant strains and contamination of resistant pathogenic bacteria e.g. Salmonella spp. as input have facilitated to development of pool of resistant bacteria. Indicator

Clostridium tetani is a species of pathogenic bacteria which causes the disease tetanus in humans (World Health Organisation [WHO], 2008). Bacteria are prokaryotic microorganisms which contain various structural components. These components include a cell wall and outer membrane which is discovered by the gram stain procedure (Kratz, 2011). C. tetani are gram-positive bacteria therefore its cells have a thick wall however they do not possess an outer membrane ("Vaccines and immunisations," 2015)

Micro 2924, section 310 July 21, 2010 Escherichia Coli Introduction: Esherichia coli also known as E. coli is a bacterium that lives in your gut. (1). it was founded by Theodore von Esherich in 1888. There are many people that can get the bacteria. Also there are thousands of strands of E.coli. Six E. coli O157 outbreaks were identified during 2007. Four of the outbreaks involved foodborne transmission. (Eshericha Coli). Six Minnesota cases and one Wisconsin case with the same or closely-related

Bacteria Growth in Different Test Tubes Introduction The purpose of this lab is to learn about restriction enzymes, plasmids, and cloning genes. In class, we learned a lot about the structure of DNA and genes, which were both very helpful while performing this experiment. Restriction enzymes have the ability to cut DNA at specific sequences. Plasmids are perfect for genetic engineering because they can replicate and initiate transcription. Performing this experiment helped us learn more about the

Human Microbe Bacteria surround us, they cover our bodies from our phalanges on our feet to the follicles of hair on our craniums. Therefore, it is important to realize that while, the majority of these astounding microorganisms are beneficial, certain bacteria are devastating to our health. When referring to bacterium there are two major categories that you may organize them by, are the beneficial bacterium or harmful bacterium. Beneficial bacterium are those engaging in a symbiotic relationship

There are many factors contributing to our inconclusive results, ultimately leading us to reject our hypothesis. All of our bacteria came from EMB plates, which supported our claim that a gram-negative bacterium grows on the surface of paper money. Out of the twenty different monetary samples we swabbed for bacterial growth, only the fifty-dollar currency bacterium was cultured; all three of our fifty-dollar bill samples grew. The fifty-dollar bill has an average life cycle of 55 months, which is
