a. chlamydias.
b. spirochetes.
c. Euryarchacota.
d. Cyanobacteria.
e. Archaea.

- A budding artisanal cheesemaker is trying to establish her own starter culture, but there is an archaeal contaminant she finds difficult to get rid of. Instead of producing lactic acid, the Archaea ferments the milk sugars into alcohol, an extremely undesirable effect in cheese making, therefore ruining many of her cheesemaking efforts. She asked microbiologists for help to find a strategy that may hinder the growth or even kill the archaeal cells, but not the lactic acid bacteria (LAB) in rest of her starter culture. The microbiologists come up with different things to try. In the table below are some strategies that she tries. Practice Question Chapter 3 5. Predict what the results are going to be for each strategy she uses. Assume each inhibitor is specific. Assume she doesn't know the species of Archaea that is contaminating her starter culture. Answer yes, no, or maybe where appropriate, explain your answer in the last row of the table below.

- Consumers are advised to avoid stuffing a turkey the night before cooking (where the stuffing would be made on the stove and then placed in the turkey), even though the turkey is refrigerated. A homemaker questions this advice and points out that the bacteria of human disease grow mainly at warm temperatures, not in the refrigerator. What explanation might you offer to counter this argument?arrow_forwardOne organism found in a termite’s gut is Mixotrichia paradoxa. This strange creature looks like a single-celled swimming ciliate under low magnification. However, the electron microscope reveals that it contains spherical bacteria rather than mitochondria and has on its surface, rather than cilia, hundreads and thousands of spirilla and bacilla bacteria. You are the scientists who first observed this organism. How would you describe this organism- single-celled? Aggregate? Colony? Multicellular? Can the structure of this organism give you any insight into the evolution of eukaryotic cells? (Hint: the endosymbiosis hypothesis)arrow_forwardDescribe the three major domains of life: Archaea, Bacteria, and Eukarya. Explain what the three domains have in common and how they differ. Define viruses, and explain how they relate to living cells. Explain how microbial diseases have changed human history. Explain the tenets of Cell Theory Describe how microscopy led to the Germ Theory of infectious disease Define the germ theory of disease.

A local villager comes to you sick with nausea, diarrhea and vomiting and you suspect they may have food poisoning. Several different types of bacteria can cause food poisoning including Campylobacter jejuni, Staphylococcus aureus, and Salmonella tyhphirium. How will using a microscope help you to identify which of the three bacteria are responsible for making your patient sick so that you can administer the correct antibiotic?arrow_forwardBacteria that can survive in extreme environments are called: a-Anaerobes b-Saprophytes c-Aerobes d-Archaebacteriaarrow_forward
- What is/are the usual habitat(s) of endospore-forming bacteria thatare agents of disease?a. intestines of animals b. soil c. water d. foodsarrow_forwardBacteria of the genus Mycoplasma are distinguished from other bacterial cells by 1) cell walls composed solely of amino acids. O 2) the absence of a cytoplasmic membrane. O 3) the absence of a cell wall. O 4) Have large capsules. 5) the presence of mycolic acid in their cell walls.arrow_forwardA clinical microbiologist is studying a microbe that can cause infections and gastrointestinal disease in humans, and which can also survive and reproduce in mice. A dormant cyst form of the microbe infects human hosts through fecal-oral transmission if they come in contact with mouse droppings and don’t wash their hands before eating. The organism grows in long filaments when grown at 20-28 deg C, and forms round/ovoid cells when grown at temperatures above 28 deg C. Sexual reproduction (fusion of haploid gametes) occurs in both humans and mice. A cell wall is present, and cells contain nuclei. This microbe could be which of the following? Bacterium Fungus Virus Protozoanarrow_forward
