As the immune system increases fluids in a tissue resulting in swelling and increased mucus production during infection a bacteria will utilize to maintain themselves in a patient's tissue. Salmonella would utilize these to maintain themselves in the gastrointestinal tract and not be pushed out of the host by peristalsis. O Adhesins O Exoenzymes O Endotoxins O Exotoxins O None of the above apply
Which of these statements is false? Microbiology is one of the largest and most complex of the biological sciences O Microbiology is a specialized area of biology that deals with tiny life forms that are not readily observed without magnification. The major groups of microbes included in this field of study are bacteria, viruses, fungi, protozoa, algae, and helminths. Every single microbiologist works in a lab.
Which of the following is NOT a health benefit of the microbiota? O compete for food sources synthesize antimicrobial compounds O prevent pathogen colonization O synthesize food
Which statements describe ways in which antibiotic resistant bacteria can spread? Health care workers become infected after have interacting with sick patients. Hospital visitors transfer resistant bacteria from patients to family or community members. Animals raised for meat or milk are routinely given antibiotics. Animal feces is used as a fertilizer for food crops. Antibacterial soaps are used at home, at schools, and in hospitals.
The CDC estimates that there are 1,000,000 cases of Salmonella infections , with 380 deaths each year in the US. Salmonella infections are a good example for O a disease for which number of cases annually can be easily estimated because the only successful treatment is with prescribed antibiotics an underreported disease because it is self-limiting, i.e. patient recovers without medical intervention
How would you argue against this statement: "To help prevent any type of bacterial infection all bacteria should be wiped out/killed."
The table below shows the symptoms of some diseases that are caused by bacteria. Disease Symptoms vomiting, abdominal pain, coughing, muscular weakness, visual disturbance botulism inflammation of lungs, fever, shortness of breath, fluid in lungs pneumonia typhoid fever red rashes, high fever, intestinal bleeding tetanus uncontrolled contractions of voluntary muscles Which two diseases listed in the table affect the digestive system? Be sure to support your reasoning with evidence from the table. Please write in complete sentences.
E. coli and Salmonella are bacteria. O Gram positive O Harmless O Extinct O Gram negative bacteria have a thick, outer layer of peptidoglycan and stain purple. Gram negative O Infectious O Non-infectious Gram positive
Escherichia coli is a good indicator of water pollution because this bacterium Group of answer choices -grows only in high-salt environments -forms spores -is commonly found in human intestines -is resistant to most antibiotics -undergoes mutations readily Waterborne diseases begin as -infections -intoxications -diseases -abrasions A major organism considered to cause food-borne infection is Group of answer choices -Salmonella. -Staphylococcus. -Pseudomonas. -Bacillus.
Why are most Gram-negative bacteria resistant to penicillin? the outer membrane of Gram-negative cell wall prevents diffusion of penicillin O endopsores made by Gram-negative bacteria are resistant to penicillin the waxy cell wall of Gram-negative bacteria prevents diffusion of penicillin Gram-negative bacteria have thick layers of peptidoglycan which prevents diffusion of penicillin
What is an antibiotic? it is any type of chemical that is toxic it is a general disinfectant effective against most types of cells and viruses it is a type chemical produced by a bacterium or fungus that has the potential to control the growth of another bacterium allows exchange of organisms between your bacteria culture and the environment it is a macromolecule produced by the vertebrate immune system that helps destroy foreign cells
Bacteria have three major methods of resisting antibiotics. They may lack (or modify) the feature that the antibiotic targets, so that the drug has little or no effect. The may have an enzyme that helps them break down and inactivate the antibiotic. They may have efflux pumps that remove the drug from the cell. Which method of resistance are Gram-negatives particularly famous for? Group of answer choices target modification enzymatic breakdown horizontal transfer efflux pumps
