My partner and I were given unknown number 3 in the laboratory. After performing various tests over the course of a few weeks on our unknown, we came to the conclusion that our unknown organism is Klebsiella pneumoniae (K. pneumoniae). K. pneumoniae is a gram negative bacillus shaped microorganism. We observed that K. pneumoniae is a nonmotile organism. We performed multiple tests on our unknown culture, therefore we are very confident that it is correctly identified. We identified that K.…

Question: How do different surface areas affect bacterial growth? Hypothesis: I think that the bacterial growth will be different in terms of size, shape, type and color. I think that different bacterias will grow on each quadrant because each surface of collection has unique bacterias. The unique bacterias will contribute to the fact that the size and color of them will also be different. I also predict that the growth of bacteria on the toilet seat (1D) will have the most colonies because it…

A culture of different species was brought to the lab to be analyzed in order to identify the pathogen causing disease. The goal of this lab was to be able to identify the unknown pathogen, match the patient to the bacterium, and being able to identify the disease it causes. At the beginning of class, the TA handed each student an agar plate containing some unknown bacteria, each one was numbered. Mine was number 14. The teacher then asked the students to use the techniques used in class…

Bifidobacterium bifidum is one of the most commonly probiotic bacterium found in the body of mammals. This popularity of this pathogen is probably due to its digestion aiding abilities. Bifidobacterium bifidum is rod shaped and commonly found in the intestines of mammals, including humans. The pathogen is beneficial to the body and can be found in intestines mainly but also, breast milk and the vaginal area. The amount of Bifidobacterium Bifidum in your system can be increased by taking certain…

Title: Which Antibiotics Kill the Most Bacteria? Caroline Gorman April 2, 2016 HB bl. 6 Purpose: The purpose of this lab was to determine which of five common antibiotics would kill the Rhodococcus rhodochrous bacteria. Hypothesis: Out of the five tested antibiotics, doxycycline will kill the most Rhodococcus rhodochrous because it is generally used to treat mild infections. This will be tested by spreading the bacteria on agar in a Petri dish and adding a small amount of each antibiotic…

coli, in a water source is an indication of the presence human or animal waste matter in the water. These bacteria are a type of fecal coliform bacteria found in the intestines of humans and animals. Drinking water that contains E. coli bacteria may cause diarrhea, abdominal cramps, headaches and nausea. Young children and elderly people may be more susceptible to the adverse effects of E. coli because their immune systems are delicate. Polluted…
