respiratory diseases or viral infections and people who have weakened immune systems are at greater risk. Pneumonia bacteria are present in some healthy throats. When body defenses are weakened in some way‚ by illness‚ old age‚ malnutrition‚ general debility or impaired immunity‚ the bacterial can multiply and cause serious damage. Usually‚ when a person’s resistance is lowered‚ bacteria work their way into the lungs and inflame the air sacs. The tissue part of a lobe of the lung‚ an entire lobe‚ or

INTRODUCTION The enzyme catalase converts hydrogen peroxide (H2O2) to water and O2. The evolution of O2 causes bubbling. Thus‚ catalase-positive organisms that are mixed into hydrogen peroxide will cause bubbling (catalase-negative organisms will not). This test is good for distinguishing between Gram-positive cocci in chains (catalase negative) versus Gram-positive cocci in clusters (catalase positive). The coagulase test is used to differentiate Staphylococcus aureus from coagulase-negative

Aims The purpose of the two experiments was to determine the fundamental effects that temperature has on the growth and survival of bacteria. During the first experiment five different bacterial broth cultures of Escherichia coli‚ Pseudomonas fluorescens‚ Enterococcus faecalis‚ Bacillus subtilis and Bacillus stearothermophilus were individually incubated at temperatures of 5‚ 25‚ 37‚ 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different

Material Appendix B – Identifying Bacteria Bacteria identification is accomplished in a number of ways. Two common tools microbiologists use to identify unknown bacteria include dichotomous key and biochemical tests. The dichotomous key is useful when a microbiologist only needs to know which group an unknown microbe belongs to on a general level. When a microbiologist needs to identify a specific bacterium‚ biochemical tests are used. PART ONE: GENERAL BACTERIA IDENTIFICATION Review the dichotomous
