Title Antibiotic Prescribing Pattern Across Four Health Clinics in Putrajaya. Background The use of antibiotics have effectively prolonged life expectancy and are currently one of the most commonly prescribed drugs in healthcare facilities worldwide1. Unfortunately‚ widespread use and misuse worldwide have led to the emergence of ‘super bugs’ and other drug-resistant bacteria2-4. Excessive and inappropriate use of antibiotics contributes to the development of bacterial resistance5-7‚ an increased

different ways they suppress bacteria‚ and the efficacy of antibiotics depends on the structure of the bacteria which they are targeting. The specific bacteria being studies in this experiment is E Coli and Enterococcus. E Coli is a bacteria which may cause diarrheal disease (CDC.gov)‚ and Enterococcus may cause urinary tract infection (Kau). Bacteria are primarily classified as either Gram Positive or Gram Negative. Gram Positive Bacteria lack an outer membrane and have multiple layers of peptidoglycan

Chapter 6 Microbial Growth 1 Growth • increase in cellular constituents that may result in: – increase in cell number • e.g.‚ when microorganisms reproduce by budding or binary fission – increase in cell size • e.g.‚ coenocytic microorganisms have nuclear divisions that are not accompanied by cell divisions • microbiologists usually study population growth rather than growth of individual cells 2 The Growth Curve • observed when microorganisms are cultivated in batch

Microbiology UNKNOWN LAB REPORT Kateryna Petrakova INTRODUCTION Microorganisms cause a great amount of diseases. For healthcare providers it is very important to be aware of what organisms are pathogenic and cause a disease and‚ therefore‚ to find an appropriate treatment. Different microorganisms require various environments in order to replicate and to become dangerous for a person’s health. An integral part of any medical treatment is to be able to recognize and

negative organisms were positive for glucose except for two. Since our organism tested negative for glucose it helped narrow it down to only those two organisms‚ Alcaligenes faecalis and Pseudomonas aeruginosa. The other tests that we performed on our unknown were not really helpful when it came to determining if it was Alcaligenes faecalis or Pseudomonas aeruginosa because they both had all the same characteristics when it came to the lactose‚ mannitol‚ motility‚ indole‚ citrate‚ H2S‚ urease‚ methyl red

flooded the plate with Iodine and were able to observe and record starch Hydrolysis. (Table 1) * In order to test carbohydrate catabolism under anaerobic conditions we tested cultures of Pseudomonas aerugenosa‚ Escherichia coli‚ and Alcaligenes faecalis in tubes containing a glucose medium. After inoculating each tube with each of the bacteria 5mm of mineral oil was poured into one of the tubes containing bacteria to observe anaerobic respiration and while one remained without mineral oil.

Microbiology Laboratory Report Identification of Unknown Bacteria 03/10/05- 04/01/05 Authors: Richard Hendricks‚ Jessica Prebish; NMU Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques

Antimicrobials Anti-bacterials * Need a drug selectively toxic to bacterial cells but won’t harm human cells * Many drugs that achieve this still have side effects as every drug is a poison Bacterial Infections * Immunocompromised especially vulnerable * Opportunistic infection – Infection caused by pathogens that usually do not cause disease in a healthy immune system. A compromised immune system however presents ‘opportunity’ for pathogen to infect * Prophylaxis

OBJECTIVE: 1. To distinguish the bacteria abilities to metabolize various substrates and end products formed. 2. To observe the growth of different bacteria species in term of structures and its morphology based on different chemical substance applied. 3. To observe physiological and immunological properties utilized by different species of bacteria. INTRODUCTION: Bacteria biochemical testing can determine the types and numbers in terms of colony forming units of bacteria present in a

INTRODUCTION: In this laboratory exercise explore the differences of microorganism and continue our use of specialized media and use some biochemical testing.This report discloses the basic laboratory instruments will be used in each of our practices .It is of great importance to recognize and identify the different instruments and laboratory tools‚ because in this way will we be able to use them properly and also to call them by name and know why.
