Change in the color of litmus from purple to pink or pink-red throughout the tube. Upon further incubation a white ring of litmus forms at the bottom of the tube at the pink-red color is now present only at the top of the tube. Still further incubation leads to the formation of a rennet curd at the bottom of the

Ventilator Associated Pneumonia is one of the many nosocomial bacterial infections that patients in Intensive Care Units might acquire during their stay. VAP is the number one hospital acquired infection contracted in ICU’s. It occurs within 48 hours from prolonged oxygen therapy by endotracheal tube or tracheostomy. Intubation compromises the oropharynx and trachea by obstructing the normal airway. This allows easier access for microorganisms in gastric and oral secretions to enter the lungs and

Unknown Experiment Introduction: The purpose of this experiment is to distinguish and indentify an unknown bacterium. There are several tests that can help one eliminate and narrow down the options. The most useful test‚ and the very first one done‚ is a gram stain. This test will tell whether the bacterium is gram-positive or gram-negative. After the type of gram stain is identified‚ the tester has a wide array of differentiating tests at their disposal. Based on the results from these

Microbial Diversity and Ubiquity Microorganisms are microscopic organisms that are so small that that they can only be visualized by the aid of a compound-brightfield microscope. While we generally cannot see individual microorganisms with the naked eye‚ they are present in virtually every habitat known to man. Microorganisms can be prokaryotic—the bacteria or eukaryotic—the algae‚ protozoa or fungi. While viruses are acellular they are also studied in the scope of microbiology because

To find the most possible one‚ the obtained ORFs were aligned with lipase encoding ORF from Alcaligenes faecalis resulted one sequence

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
