Rickettsia‚ mycoplasma and chlamydia are three very unique bacterias. Here are a few reasons why for each bacteria. Rickettsia is an obligate intracellular gram-negative bacteria. This type of bacteria is very small and is bacilli shaped. Rickettsia causes rocky mountain spotted fever‚ rickettsia pox‚ epidemic typhus and murine typhus disease. It is found in ticks‚ lice‚ fleas‚ mites‚ chiggers and mammals. It is transmitted by a bite (vector transmission) from an infected tick‚ mite‚ flea or any

Experiment 9: Growth curve of Serratia marcescens Abstract Bacteria grows by binary fission. The aim of this experiment is to follow the growth of Serratia marcescens in nutrient broth at 37oCby recording the changes in turbidity (cloudiness) by measuring the absorbance of visible light (600 nm) and also to prove that there is an increase in the cell number and not just in mass during the growth. In the experiment we measure the full growth curve of Serratia marcescens by measuring the absorbance

bacterium was gram-negative bacilli that did not utilize citrate‚ and the ability to hydrolyze urea using urease. These results indicate that the identity of unknown number 34 is Proteus mirabilis. Introduction Proteus mirabilis is a gram-negative bacillus bacterium. It is found naturally in the human gut flora. However‚ if P. mirabilis comes into contact with the urinary tract‚ urinary tract infections can result. Urinary tract infections caused by P. mirabilis are correlated

Antimicrobial Activity of Cilantro on Staphylococcus Epidermis and Escherichia coli Abstract Antimicrobial effects of cilantro against the gram positive bacteria S. epidermis and the gram negative bacteria E. coli were looked at. We predicted that cilantro would act as an antibiotic against S. epidermis but not to E. coli because S. epidermis does not contain an outer membrane whereas E coli. does. We predicted that the semi-permeable outer membrane of E. coli would protect the bacteria from

Pneumonia can be a serious threat to your health. Since the early 1960’s pneumonia has been second only to lung cancer as a leading cause of death related to respiratory diseases. Pneumonia is an inflammation or infection of the lungs. The lungs’ air sacs fill with pus‚ mucus‚ and other liquid and can not function properly. Oxygen can not reach the blood. If there is not enough oxygen in the blood‚ body cells can not work right and might die. Lobar pneumonia affects a section of a lung. Bronchial
