survival capabilities in a moist environment as well. Unfortunately, they are resistant to several antibiotics and disinfectants. The most prominent species is Pseudomonas aeruginosa, which is considered the model of an opportunistic pathogen (Tortora, & Funke, 2013). Pseudomonads are responsible for the continued outbreaks of Pseudomonas dermatitis. Their mode of transmission is associated with swimming pools, jacuzzis, and saunas. These are all examples of a moist environment that is needed for
Pseudomonas aeruginosa (P. aeruginosa) is a gram-negative, rod-shaped aerobic bacterium. It is a primary cause of hospital-acquired infections. P. aeruginosa is primarily a nosocomial pathogen. It also acts as an opportunistic pathogen, which can only infect a host that is immunocompromised, due to an underlying disease or medication. Although, P. aeruginosa can cause damage to virtually any tissue in the body, it almost never affects the tissues of healthy individuals. It is a problematic pathogen
against “gram-negative bacillary infections, and infections caused by staphylococci when penicillin or other less toxic drugs are contraindicated.” (Vallerand, Sanoski, & Deglin, 2013, p.131) Tobramycin is commonly inhaled to manage the bacteria Pseudomonas aeruginosa in patients with Cystic fibrosis. Tobramycin inhibits the growth of bacteria at levels of 30S ribosome. The antibiotic is poorly absorbed from the gastrointestinal tract, however it is absorbed rapidly by intramuscular injection.

The unknown microorganism in question is believed to be Pseudomonas fluorescens. This bacterium is an obligate aerobe possessing multiple polar flagella for motility purposes and flourishes in twenty-five to thirty degree Celsius environments (microbe wiki 1). It also produces siderophore pyoverdine which is responsible for chelating iron when environmental concentrations are low (microbe wiki 1). These siderophores are responsible for this microbe’s ability to fluoresce under ultra violet light
BioPatch, and alternatives like Tegaderm CHG, are an important first step in helping prevent catheter-related bloodstream infections (CBIs). As CBIs rank among the most frequent and potentially lethal nosocomial infections, the need for a device to cut down infections at the insertion site has increased. The growing numbers of infections has driven companies to consider a three-tiered approach: a maximal aseptic barrier at insertion, proper site maintenance, and hub protection. With BioPatch and
The cause of acute, persistent, or relapsing clinical infections is often due to multidrug resistance and/or antibiotic tolerance. Pseudomonas aeruginosa is a widespread, opportunistic, gram-negative, bacterial pathogen that readily develops multidrug resistance and is responsible for causing acute and persistent infections (Starkey et al, 2014). P. aeruginosa thrives in moist environments, primarily as waterborne and soil-borne organisms (Chen, 2015). It is found on medical equipment including catheters
common are: urinary tract, surgical wounds, respiratory tract, skin, blood, gastrointestinal tract, and central nervous system (Abedon). According to the CDC, the most common pathogens that cause nosocomial infections are Staphylococcus aureus, Pseudomonas aeurginosa, and Escherichia coli (EHA). Methicillin resistant Staphylococcal aureus (MRSA) is a strain of bacteria that is commonly... ... middle of paper ... ...evaporated into the air and remains suspended for a period of time (Georgia Pacific)
Have you ever seen a movie or read a book where they can tell what your child will look like or if they have a disease or birth defect. Or have you ever wondered how the world would be shaped if we could have clones or even erase genetic diseases. All of these things are theoretically possible with stem cell research. If we are able to reach this point what would we have to sacrifice in the process. To understand humanity would we have to sacrifice the values that truly make us human? What would
Research of Food Sample : Saltwater fish (Tuna) INTRODUCTION The availability of saltwater fish products in the market was depend on the coastal fishing vessels operation. One species that is widely consumed around the globe is Tuna (Thunnus sp.). Tuna is widely available both in Pasific and Atlantic ocean. The nutritional content of tuna, both bluefin tuna and yellowfin tuna according to the USDA National Nutrient Database can be seen in Table 1 (1). Fish nutritional composition is varied between
parent. Remember that chromosomes are made up of DNA or deoxyribonucleic acid. DNA is made up of genes, and genes are made up of building blocks called base pairs. The specific gene responsible for CF was identified in 1989 on human chromosome 7 (Pseudomonas Genome Project, 1998). A mutation, or change in the genetic material, resulting in a substitution or loss of one of the base pairs causes the CF gene to be abnormal (Cystic Fibrosis Foundation, 1995). CF does not affect all people the same way
plants such as corn, paddy,weeds and other plants and microorganisms or still under favorable soil conditions oxidized to form nitrites and then to nitrates. The bacteria that complete the ammonification process are Bacillus, Clostridium, Proteus, Pseudomonas, and Streptomyces and known as ammonifying bacteria. The important step in ammonification is deamination which means removal of the amino group from proteins and amino acids and results in the discharge of ammonium. Ammonium is return to the environment
attachment of microorganisms to plant roots, functional flagella are important for bacterial motility. The crucial role of motility for successful rhizosphere colonization is somewhat controversial because some studies have indicated that motility of Pseudomonas is not required for root colonization in wheat and soybean (Howie et al. 1987). However, flagella were shown to be essential for colonization of potato roots (de Weger et al. 1987). Studies confirming the role of motility in the colonization process
Journal Article Review: Microbial Contamination of Contact Lens Storage Cases Donna Vega Microbiology 140 Professor Dr. Pepper October 16, 2014 Microbial Contamination of Contact Lens Storage Cases Contact lenses have become widely known as a great vision corrector for many eyeglass wearers. However, the use of contact lenses can sometimes cause extreme eye infections, such as microbial keratitis, which results in blindness. In the article, “Microbial Contamination of Contact Lens Storage

Oil plays a immense and vital role in our society as it is organized today. Oil represents much more than just one of the main energy sources used by mankind. The oil and petroleum industry plays an extremely important role in the economy and politics of our country. Petroleum products, besides being an important energy source, serve as feedstock for several consumer goods, which in turn plays a growing and relevant role in people’s lives. But apart from all pertinent role the oil industry plays
2.1 Surfactant and biosurfactant The amphiphilic molecules which is known as surfactants have been used widely in different industries including petroleum, environmental, food, agricultural, bioprocessing, cosmetic, and biological industries. Surfactants contain a hydrophilic part and hydrophobic part which make them capable to reduce surface and interfacial tension of liquids. However, these compounds are chemically synthesized which is mainly petroleum-based and toxic to the environment. These

Some important lipase-producing bacterial genera are Bacillus, Pseudomonas and Burkholderia and fungal genera include Aspergillus, Penicillium, Rhizopus, Candida. Different species of yeasts belonging to seven different genera include Zygosaccharomyces, Pichia, Lachancea, Kluyveromyces, Saccharomyces, Candida, and Torulaspora
potentially affect the prevalence of antibiotic-resistant bacteria, which is not enough to create a protocol that all healthcare facilities across the country should follow. He created his own study focusing on the strains of multidrug-resistant Pseudomonas aeruginosa, bacteria that cause bloodstream and/or pulmonary infection that can be life-threatening (p. 382). Buford et al. compares the differences between conventional techniques and molecular techniques in diagnosing multidrug-resistant infections
INTRODUCTION: Bacteria play a very decisive role of silently getting the nature purge of the dead matter through the disintegration of dead organic matter by the microbes. They use them as a foundation of nutrients, and in turn help in recycling the organic compounds trapped in the dead matter. Through this process, other organisms also get profited, who can use the simpler forms of organic compounds/nutrients released from the dead matter by various bacteria. Figure 1: Decomposition
