Respiratory Infections

Respiratory infections are infectious diseases of the respiratory tract that are mostly caused by bacteria and viruses. They cause infections of the throat, sinuses, airway path, and lungs. Respiratory infections are typically divided into two types: upper tract respiratory infection and lower tract respiratory infection.

Question

Four days after a patient has intestinal tract surgery
they develop an abdominal infection caused by a G-
obligate anaerobe. What is the most likely agent of
the infection?
O Clostridium perfringens
Escherichia coli
Peptostreptococcus sp.
O Klebsiella pneumoniae
Bacteroides fragilis

All of the following are examples of mechanisms of
antibiotic resistance EXCEPT
Tetracycline resistance by efflux pumps to pump
antibiotic out of the cell
Secretion of urease enzyme to produce ammonia
(NH3) destroying mucous producing cells
Enzymatic destruction of penicillin family
antibiotics by beta-lactamases
Alteration of tetrapeptide chains by Vancoycin
Resistant Enterococci (VRE)
Enzymatic modificaton of aminoglycosides to
prevent antibiotic binding to the target molecule

Treatment includes pressurized hyperbaric oxygen. Which of the following apply? None of the statements apply Streptococcus pneumoniae causing community aquired pneumonia. Klebsiella pneumoniae causing cellular degradation in pulmonary tissues Clostridium perfringens causing gas gangrene resulting in myonecrosis by synthesis of acids and gases Staphylococcus aureus producing lipases and proteases
Consider a gram-negative pathogen isolated from marine mammals. This pathogen is subjected to a series of tests and found to have the following characteristics: oxidase-positive, does not hydrolyze urea, produces indole, does not produce acetoin. Which of the following could it be? O Pasteurella mulocida O Klebsiella pneumoniae O Yersinia enterocolitical O Mannheimia haemolytica
Helicobacter pylori is able to use urease to neutralize the stomach environment because the enzyme produces: acids O bases • carbons amino acids
Haemophilus influenzae must be grown on special blood agars, e.g. chocolate agar, which is blood agar treated with heat to release gorwth factors and to destroy inhibitory enzymes. Thus Haemophilus is described as fastidious oxygen-sensitive oxygen labile voracious
Bacteria that are obligate intracellular pathogens of humans are considered to be Autotrophs Heterotrophs Photosynthetic Hyperthermophiles Chemolithotrophs Which of the following statements best describes the pathogenesis of Clostridium botulinum? It elaborates an exotoxin that is a lecithinase that causes tissue necrosis. It elaborates a toxin that suppresses the release of inhibitory neurotransmitters. It produces a polysaccharide capsule that inhibits phagocytosis and contributes to invasion of the central nervous system. It elaborates a toxin that inhibits the release of acetylcholine at cholinergic synapses. It produces a leukotoxin that leads to abscess formation.
Why mightproteorhodopsin make a bacterium such as Pelagibacter morecompetitive in its habitat?
clostridium botulinum is a bacterium usually present in soil that may cause botulism. Briefly explain why one or few cells of a pathogenic bacterium, such as clostridium botulism, by itself typically does not secrete a toxin, despite the species as a whole being characterized as toxin producing.
holsappleeus scarius is a normal flora of the human intestenal tract. its facultative anaerobe capable of catabolizing carbohydrates. which conditions will give them the most growth?
Which of the following bacterial species is considered normal flora of the mouth? O 1) Streptococcus mutans 2) Escherichia coli 3) Klebsiella pneumoniae 4) Staphylococcus epidermidis
Mutant strains of Helicobacter pylori that lack the ability to produce urease fail to cause infection when they are swallowed. Infection occurs, however, if a tube is used to introduce them directly into the layer of mucus that overlies the stomach epithelium. What does this imply about the role of urease in the bacterium’s pathogenicity?
Some S. aureus stains have a number of virulence factors including O Lipase which convey resistance to lipids and staphlokinase which clots the blood. O Lipase which digests lipids and B-lactamase which breaks the matrix between cells. O coagulase which dissolves blood clots and staphlokinase which clots the blood. coagulase which clots the blood and B-lactamase which conveys resistance to penicillin.
