Question
Chapter 45.6, Problem 1EQ
Summary Introduction
To determine: The hypothesis that was tested in an experiment conducted by Marshall and Warren, and the background information that served as the basis of this hypothesis.
Introduction: Ulcer refers to the breaking of the inner wall of the stomach, which protects the cells from the acid produced in the stomach. In this situation, the patient feels inflammation and pain. It can be controlled by administering antacids.

Describe the negative and positive roles that biological plausibility played in establishing causation.
In 2005, J. Robin Warren and Barry J. Marshall shared theNobel Prize in Medicine for discovering the bacteriumHelicobacter pylori and for establishing experimental proofthat it plays a major role in gastritis and peptic ulcer disease.The story began when Warren, a pathologist, noticed thatbacilli were associated with the tissues taken from patientssuffering from ulcers. Look up the history of this case and describeWarren’s first hypothesis. What sorts of evidence did ittake to create a credible theory based on it?
Calculate the number of bacteria (CFU/ml) in each serum and saline sample.
What was the purpose of the saline?
Which bacteria produced more CFU/ml in serum? Why?
Provide a possible explanation for the ability of Pseudomonas to colonize mucous membranes.
Reference(s): Include at least 1 valid reference for your research in correct format (either APA or MLA) (2pts)

Probiotics are live bacteria that balance good and bad intestinal bacteria and aid in digestion or digestive problems. For example, Lactobacillus species habituate where rich carbohydrate substances are available including the human digestive and urinary tracts. In 1900 lactobacillus acidophilus was isolated by Moro from infant feces and the intestinal tract of animals and humans. Also, it was reported in the feces of milk fed infants and older persons consuming high milk/lactose diets. This microbe is also found in plant materials and agricultural products particularly milk, cheese, fermented milk products and beverages such as wine and cider. Historically, Lactobacillus species is most often known to be capable of eliciting beneficial effects on the microbiota of the gastrointestinal tract.

Thank you-arrow_forwardNodules found on the roots of leguminous plants like soybeans harbor bacteria that fix nitrogen. These nodules are an example of the intimate and specialized partnerships that have been established over time between prokaryotes and eukaryotes. Coevolution maintains these types of relationships because both participants benefit. Plants receive biologically useful forms of nitrogen needed for growth, and the bacteria reside in an oxygen-free environment required by enzymes involved in the nitrogen-fixing process. Humans also maintain intimate associations with beneficial bacteria and even archaea. In fact, the prokaryotic cells in and on human bodies outnumber the eukaryotic human cells by tenfold, according to some estimates. These microbial inhabitants help humans digest food, provide essential vitamins absorbed by the intestines, and even impact the immune system. The microbes that coevolve with plants arrive by infection of root tissue. The microbiota that coevolve with humans…arrow_forward
