E. Discussion: In order to synthesize the polymer, Nylon 6,10, we had to complete a few steps to create the chemical reaction that combined sebacoyl chloride and hexamethylenediamine. First we measured the mass of the two graduated cylinders when they were empty, and measured it again after they were filled with sebacoyl chloride and hexamethylenediamine. We did this in order to find the measurements of the reactants. When we measured the graduated cylinder when they were emptied, one weighed at
I. Attention: Imagine you have to go to McKinley because you accidentally ate spoiled food. You ask for penicillin, but doctor is unwilling to prescribe you the drug and tells you that you will recover after resting for a few days (AA). Most physicians refrain from prescribing drugs to patients because the overuse of drugs can reduce their effectiveness. Transition: However, farmers are ignoring this fact, and it is becoming a public health problem. II. Need: Farmers are giving an excessive amount
Methods Formulation of chloramphenicol ophthalmic hydrogel Formulations was prepared according in Table 1. Poloxamer 188 and poloxamer 407 each weighed and dissolved with distilled water. Then stored in the refrigerator for 24 hours. Next chloramphenicol dissolved with propylenglicol, and nipagin. The mixture was stirred until the entire dissolved and homogeneous. The materials were ready each put in a bottle 100 mL size vial, then sterilized with autoclave for 15 minutes at 121 °C. The preparations
re-sterilized. Penicillin was picked up from the container and placed an equal distance from the control disk and the side of the petri dish. Any antibiotic disks that were dropped were recorded. The steps were repeated for Ampicillin, Tetracycline, Chloramphenicol, and Streptomycin in both petri dishes. Each dish was placed in the incubator and left for 24 to 48 hours. Zones of inhibition were measured in millimeters and recorded after 24 and 48 hours. The zones of inhibition were measured by inverting
Cultural characteristics:- Cryptococcus is an aerobe requiring a temperature of 30-35 o C for its growth. It grows on most standard fungal culture media. It does not grow ≥370C. It does not grow in the presence of Cycloheximide at concentrations used in Sabouraud’s dextrose agar (SDA). It has ability to produce melanin pigment by using various precursors of melanin in the media. I] Culture Media For primary isolation: - . For primary isolation of cryptococcus bacteriological media like blood
Results Gram Stain: The Gram Stain test was performed on our unknown bacteria F#1729 resulting in in a Gram-negative (-) result meaning that it contained a thin layer of peptidoglycan. This thin outer membrane is composed of lipopolysaccharides and cannot retain the crystal violet iodine used, instead it sloughs off when rinsed with the ethanol alcohol. This leaves the color unretained and the counterstain safranin is absorbed, staining the bacteria pink. Once the slide was ready, we were able to
ABSTRACT Wound is a breach in the skin and the exposure of subcutaneous tissue following loss of skin integrity. Post-operative wound infections are major global problem in the field of surgery leading to many complications, increased morbidity and mortality. A total 75 pus samples were collected from post-operative wound infections of which 63/75 (84%) bacterial isolates were obtained. Among the isolates, 29/63 (46%) were Gram positive and 34/63 (54%) were Gram negative organisms. The percentage
INTRODUCTION The purpose of this essay is to conduct a comprehensive critical appraisal of a research paper titled ‘Chloramphenicol treatment for acute infective conjunctivitis in children in primary care’ that was carried out by Rose et al. (2005) in the United Kingdom (UK). The aim of evaluation is to critically concentrate on the strength and limitation of the study. Firstly, a clear definition of critical appraisal and its importance will be highlighted, going on further will be the critical
first line of antimicrobials has complicated the selection of drugs for the treatment of shigellosis. Sulphonamides were first introduced in the early 1940s and all Shigella strains were sensitive to this drug. In 1940s, tetracycline followed by chloramphenicol, were recommended for the treatment of shigellosis because sulphonamides became ineffective. Soon, resistance to these two drugs was observed and ampicillin and co-trimoxazole came to the rescue and were found to be clinically highly effective
Animal testing is cruel and immoral because, approximately every year one million animals die from having experiments on them for different types of cure for human’s diseases. One solution is to stop the animal testing. One of the alternatives is The Non-Invasive technique and Vitro testing. ´´I am not interested to know whether vivisection produces results that are profitable to the human race or doesn’t the pain which it inflicts upon unconsenting animal is the basis of my enmity toward it, and

S. aureus ATCC 29213 was used as the quality control in
The causitive agent of the Plague is Yersinia Pestis. It is a gram negative, zoonotic and epizootic. It is a rod shaped bacteria that is a meiotrophic organism. Some scientist have developed CryptFind which is a method of theorectically testing the genomes. There are limitied rescourses for doing research since this bacteria poses such a threat to society. Picture a man in a bird suit. He is wearing a hat, mask that looks like a bird beak, goggles, and a long gown. Sounds like a halloween costume
It's amazing what our bodies can do. They fight off diseases with extremely complex systems. Why can we fight off Influenza today, but 100 years ago a staggering number of people died from it? The reason is this, most people live in areas where vaccinations are available and they can also receive antibiotics to fight off diseases. . The advancement in technology also has to do with why we can fight off diseases. Doctors and researchers are able to provide antibiotics and other treatment forms to

Our body has a natural defense mechanism that kicks into gear whenever a foreign substance enters it. When the body’s normal defenses is not able to prevent or overcome a disease, antimicrobial drugs can be used to fight off the disease. One of the most important discoveries of modern medicine was antibiotics. Things have changed from where little could be done to treat many lethal infectious diseases to now, where some of these drugs could be called “miracle” drugs. The concept of chemotherapy,
the sick. These remedies include lancing the beobus, vinegar and water treatments, and even witchcraft. There are more realistic options to treating the plague today. These options are a wide variety of antibiotics that include: Streptomycin, Chloramphenicol, Tetracyclines, and Ciprofloxacin. Sanitation has also improved since the outbreak of the Black Death. There were many consequences that resulted from the Black Death some negative and others positive. The positive influences of the disease include
recalls” (Odonkor 2013). S. aureus “is a major human pathogen, and infections caused by S. aureus resulting significant morbidity and mortality” (Williamson 2011). Some antibiotics are able to interfere with protein synthesis: tetracycline, chloramphenicol, and erythromycin. Because of the very nature of bacteria, it is important to keep a sterile environment during experiments; aseptic technique is vital. Aseptic technique involves an especial attention to cleanliness in the experiment’s environment
Diagnosis of Tetanus: For the diagnosis of tetanus there are no specific test and lab values available. Physician predicts tetanus on the basis of patient condition, like the presence of Trismus, Generalized muscular rigidity, Spasm, or combinations thereof with an open wound or puncture. Lumber Puncture. As far as lumber puncture is concerned, it does not give any information, CSF analysis is normal except increase in pressure during spasm. Culture test: If the tetanus is suspected wound culture
