A typical human body carries 30 to 50 trillion bacteria;most of these are either harmless or helpful, but a feware _____________c and thus cause disease?

A farmer working on a piece of machinery gets his shirtsleeve caught in a moving piece of the equipment. His shirt is sliced, and a sharp blade covered in mud slices through his upper arm. He attempts to control the bleeding and immediately seeks medical attention. After 3 days, he develops a fever and his arm becomes extremely swollen and painful. Pulling back the bandages, he finds that the wound has become blackened and is leaking bloody fluid. Microscopic analysis of the fluid reveals the presence of gram-positive bacilli. a. Discuss what condition the patient is suffering from and the likely causative agent of this infection. b. Explain how the patient contracted this pathogenic microbe and what virulence factors contributed to the pathogenesis seen at the wound site. c. In addition to antibiotics, the physician prescribes hyperbaric therapy. Describe what this treatment involves and how it could be therapeutic to this patient.

select a microbe that has proven to be either environmentally or socially beneficial to human beings. You are not restricted to bacteria, but the organism chosen must be considered a microbe. In your post, include an explanation of the microbe's discovery, its use (either environmentally or socially), and its normal habitat.  You should cite your research

Gram-negative bacteria are not killed by penicillin because they:    do not have ribosomes.        have an outer membrane  layer covering their peptidoglycan cell wall.        have two layers of peptidoglycan.        do not have peptidoglycan.        their ribosomes are protected with their own outer membrane layer.

Mycobacterium tuberculosis infects the upper regions of the lungs. This bacteria is classified as a(n)___.     aerobe     thermophile     saprophyte     anaerobe

Write a brief description of morphology of the salmonella typhi cell, the genus and species of bacteria and a short description of their impact on human health.

Congratulations! You have discovered a new species. It is gram-negative, nutritionally diverse (Photoautotroph, Photoheterotroph, Chemoautotroph, or Chemoheterotroph), and can be a pathogen or form symbioses. What group does it belong to? Group of answer choices Spirochetes Proteobacteria Gram-positive bacteria Cyanobacteria

A(n) ____ is a substance that can kill or inhibit the growth of infectious microorganisms antibiotic vector toxin reservoir

Each hour following the initial dose, aoenicillin to treat this infection Part B The Cure A doctor prescribes 5o0 milligrams of the body fram +he ndin of the concentntion r Date Period: Name Interim #3 Baffling Bacterla Part A The Infection We have studied bacteria and know that they reproduce by fission or simple cell division Streptococcus bacteria cause the well-known illness, strep throat, The bacteria can reproduce every twenty minutes If you Inhale a strep bacteria at noon today. a) How many will have been produced by the time you go home at 3:30 this afternoon? Explain your thinking. Prediction: b) Draw a picture of what is happening in the first 60 minutes.

The majority of antibiotics used in the clinic aremade as natural products by bacteria. Why do you supposebacteria make the very agents we use to kill them?
