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)Pseudomonas is a gram-negative rod-shaped bacterium, sometimes inhabits the intestinal tract, and considered an important cause of urinary tract infection and sepsis, however, it is not a member of family Enterobacteriaceae. Discus this statement, keep your response within 80-100 characters limit.*Robert Koch (a) proposed a set of guidelines to demonstrate that a specific pathogen causes specific disease symptoms (b) discovered Helicobacter (c) showed that biofilms consist of microorganisms (d) proposed a hypothesis for antibiotic resistance (e) demonstrated that people can be stimulated todevelop immunity to disease
- Once these pathogens enter the host the difference in environmental conditions signals for them to germinate and turn into growing cells.

Besides endospores used in transmission, what is a simple explanation to help explain how each microbe survives and grows in each location?Bacterial biofilm was defined for the first time in 1978 as a structured community ofmicroorganisms that adheres to a surface and produces an extracellular matrix ofpolysaccharides. Comment on the impact of antimicrobials for the treatment of Pseudomonasaeruginosa biofilm infections.Metachromatic granules are concentrated ____________found in _______ .a. fat, Mycobacterium c. sulfur, Thiobacillusb. dipicolinic acid, Bacillus d.

Explain three reasons why biofilms can be more pathogenic.A bacterium has the following characteristics:∙ It adheres to the human intestinal lining using a feature that protects it from phagocytes, bacteriophages, and dehydration∙ It can survive being boiled∙ It contains no plasmids and relatively little peptidoglycanWhich of the following characteristics allows this bacterium to adhere to the intestinal lining? Group of answer choices A. fimbriae B. pili C. an endospore D. a flagellumList the four cellular agents of bacterium that most antimicrobial agents such as antibiotics target.
