TITLE Lab #4 Soil –vs- Water Microbiology INTRODUCTION There are 4 learning goals for this lab: 1. Collect samples and compile data from at least 2 sources (soil; water) of your choice. 2. Identify at least 2 Prokaryotes (bacteria) and 2 Eukaryotes (fungus) in your samples. 3. Research the importance of bacteria and fungus to Earth in a non-medical context. 4. Compile a high-quality‚ 3+ resource (excluding the lab worksheet)‚ MLA-cited in-text laboratory report using the scientific method by

What are the pros and cons of each? Broad spectrum antibiotics work against many types of organisms such as gram positives‚ gram negatives and anaerobes. The great thing about this is that these are prescribed empirically so that all potential bacteria are covered until the culture results return. The problem with the misuse of broad spectrums is the resistance it can cause. The good thing about the narrow spectrum is that it covers for the specific organism that is causing the infection. The problem

a. The bacteria that causes botulism are found in soil‚ water‚ animal guts and dung. When the spores exposed to low oxygen and certain temperature‚ they produce botulinum toxin‚ able to germinate‚ metabolize‚ food sources through an aerobic respiration to produce toxin. The toxin blocks the release of acetylcholine from motor nerve endings causing paralysis symptoms. The botulism either food born‚ eating contaminated home-canned foods where the fermentation takes place. or through abrasion in the
