Pseudomonas aeruginosa

Section 1: Tests used to identify unknown pathogen Mario F. Pedero a 30-year-old male visited his physician complaining of painful bumps and soars on his leg. The patient was diagnosed with HIV + 5 years ago. Due to his diagnosis, cutaneous disorders may manifest from the condition itself, or it can lead to opportunistic infections or infections that are more extensive than normal. The patient was sent to the emergency room were the physical examination revealed skin redness, papule lesions, and…

Pseudomonas aeruginosa has many virulence factors, and can live in almost every moist environment using a wide variety of carbon sources, but it rarely causes disease. P. aeruginosa is considered a rare opportunist, due part that it cannot penetrate the skin. It can become life threatening to patients in hospitals, particularly burn victims. “In hospitals, where the most serious infections occur, Pseudomonas can be spread on the hands of healthcare workers or by equipment that gets contaminated…

(Willey et al, 2011). From the results in table1, it is shown that that Pseudomonas aeuruginosa and Staphylococcus aureus were both destroyed by of ethanol(70%) at all time set intervals of (1, 2, 5, 10 and 15 minutes). Ethanol has different capabilities as revealed in the lab experiment. . Due to its rapid evaporation nature…

Introduction: The name Pseudomonas is derived from the greek and latin words which means “false unit“ (pseudo = false, greek; monas = single unit, latin). “Monas” was used in the early history of microbiology to define single-celled organisms. In 1786 Otto Friedrich Müller, from Copenhagen, classified the bacteria and named the pseudomonads, they came into the group of vibriones (which was defined as group of shaking bacteria). Many years later it was detected that Pseudomonas are motile. They…

mascaras and eye cosmetics are Pseudomonas aeruginosa. Mascara is one of the most common cosmetic tool that is used all around the world by both women and men enhancing their beauty. Even though it may be an enhancing tool to the face, without proper disposals and care, a mascara user may suffer from a leading infection known as corneal ulcers or keratitis. Keratitis is the invasion of an infectious organism within the eye area and one of the most serious…

Information about the Bacteria Pseudomonas aeruginosa During microbiology lab, an unknown bacteria culture in liquid broth was assigned to be identified by conducting a series of various tests. Nearly twenty different tests were conducted on the bacteria, but the most important of these was Gram staining test, gelatin stab test, and oxidase test. The results of these three tests allowed for the determination of the bacteria genus and species. The first test conducted was Gram staining. In the…

cells was purple, and the peptidoglycan cell walls were thick. Furthermore, Pseudomonas Aeruginosa tested gram negative which places it with a thin peptidoglycan cell wall. This type of bacteria possesses a rod-like shape with a medium sized irregular shape. Also, the bacteria E. Coli are collectively found in large clumps with a rod shape. E. Coli tested negative for gram staining, which is the same as Pseudomonas Aeruginosa, where it possesses a thin…

It should remind that each of bacteria has specific types of toxins such as Pseudomonas secreted a different type of toxins including the Type III secreted cytotoxins, ExoS, ExoT, and ExoU, which have ability to cause the cell death. However, the Streptococcus pyogenes outputs a different type of toxin known hemolysins, which a play…

-carbon cleavage on bisphenol accompanied by oxidation causes the forming of hydroquinone (Fig 4). The similar kind of degradation pathway by bacterial isolates were reported (Zhang et al., 2007 and Janett Fischer et al., 2010). The bacterium Pseudomonas aeruginosa (PAb1) mineralize BPA in substitute pathway, similar kind of substitute pathway in the bacterium, Cupriavidus basilensis JF1 was reported (Taeko Hirano Honoda, 2000; Zhang et al., 2007 & Janett Fischer et al., 2010). In the end of…

Faecal contamination of water is routinely detected by microbiological analysis. The approach that has been adopted is to analyses for indicator organisms that inhabit the gut in large numbers and are excreted in human faeces. The presence of these indicator organisms in water is evidence of faecal contamination and therefore, of a risk that pathogens are present. If indicator organisms are present in large numbers, the contamination is considered to be recent and/or severe. Total coliforms,…
