Electrical resistance

Antibiotic resistance allows harmful microbes to exist thereby posing a major threat to many species. These microbes reject the antibiotics used to treat them; this leads to more bacterial infections, increased monetary funds to treat the infections, dangerous side effects from the use of several different antibiotics, and increased morbidity and mortality (“Impacts of Antibiotic Resistance”, 2014). The healthcare system’s approach to this widespread, global issue may be extremely expensive in…

We first evaluated whether Honokiol treatment was toxic to the APP-CHO cell line. Cells were treated with various concentrations of Honokiol (0.5 μM, 1 μM, 2 μM, 5 μM, 10 μM and 20 μM) for 24 h and cell survival was determined by Prestoblue® assay (Fig.1A). As shown in Fig.1A, when exposed to Honokiol concentrations of 10 μM or lower, the viability of APP-CHO cells was the same as untreated control cells. However, a significant decrease in cell viability was observed with 20 μM Honokiol…

The End Zone: Measuring Antimicrobial Effectiveness with Zones of Inhibition Introduction: A Kirby-Bauer test is a microbiological method used as a form of testing bacterial resistance, it’s also known as a Zone of Inhibition test (1). The way in which the Zone of Inhibition was determined in this experiment was by measuring the diameter of the resisted zone in 3 areas and taking an average. As numerical data was required for this it means that in this experiment the Zone of Inhibition Test was…

QUESTION NUMBER 1: LIST THE PRINCIPLES OF CHEMOTHERAPEAUTIC RESISTANCE Introduction: PRINCIPLE : Principle is an essential factors or elements that may have impact on the survival mechanism, which may either be from environment or the person taking the drugs or factor participating may engineer drug resistance. RESISTANCE: It is reduction in drug's effectiveness in which the drug may be fake , adulterated or substandard .Resistance is also the ability of microbes to resist toxic effects of…

List the principles of chemotherapeutic resistance. Write short note on the one you consider most important. Answer: Resistance describes reduction in effectiveness of drug to perform its normal function. It is the ability of microbes; bacterial, fungi, virus to resist the toxic effects of drugs and grow in the presence of the same concentration of drug that will normally kill or limit its growth. The following are the principles of chemotherapeutic resistance: • Pharmaceutic factors which…

SUMMARY This report is based on a case study regarding the structural failure of a spray drier. Tests and measurements were performed on the failed drier as well as on the two newer remaining driers. These tests and measurements were taken in an effort to determine the cause of the failure and to recommend precautions to take in order to extend the lifespan of the newer models. Topics covered in this report are what type of testing was used on the material, the results of the tests, and the…

Mandë Holford hopes to one day use venom from deadly snails to kill pain in human beings. This is the gist of headlines preceding articles based on Holford’s current research published by NPR and PBS. However, Holford's publications of her research tend to have less explosive and technical names such as “Characterization of Shared Pigments in Colorful Avian and Mollusk Shells” and “A Novel Bioactive Peptide Toxin from Terebrid Marine Snails”. For this case study Holford’s research paper titled…

treating them. S marcescens has an intrinsically high resistance to a broad spectrum of antibiotics, in the late 1970s S. marcescens was usually susceptible to kanamycin and always susceptible to gentamicin in vitro (Yu et al., 1979), but reports later emerged about strains that were resistant to a broad range of antibiotics, including gentamicin (Meyer et al., 1976; Yu et al., 1979) today, the literature is filled with cases of S. marcescens’ resistance to almost every class of antibiotic in…

Introduction Clinical laboratories have relied historically on phenotypic methods (i.e. culture and biochemical tests) to identify microorganisms. This can be time consuming task especially with slow growing organisms such as Mycobacterium tuberculosis. Molecular methods are now well established in the diagnosis of infectious disease. . (Harwood 2012). For the purpose of this essay I will give a brief overview of both traditional and molecular methods that re used today. I will focus on the pros…

Impetigo and Erysipelas are a bacterial- skin infection diseases. They are both caused by hemolytic streptococcus bacteria, also Impetigo is caused by another kind of bacteria which is called staphylococcus aureus. According to Hecht (2017), there are three types of Impetigo - nonbullous, bullous and ecthyma- while Erysipelas has one type only. The former is found in the tropical areas and subtropical (Marks,n.d.). Similarly, Erysipelas is common in hot and humid weather (the international…
