What stain would you use when looking for organisms like Borrelia, Trypanosomes, Rickettsiae, Chlamydia and Plasmodium?



A patient presents with an infected wound after abdominal surgery. The pus is very stinky. What type of antibiotic would be ineffective in treating this condition?

He likely has an anaerobic infection. Aminoglycosides require O2 to enter the bacteria and would be ineffective against anaerobes because they grow in oxygen poor environments.


What makes a bacteria an obligate anaerobe? List 3 bacteria that fall into this category.

The bacteria cannot use O2 as the final electron acceptor in the ETC. They lack catalase and cannot dispose of H2O2 produced in the presence of oxygen. They lack superoxide dismutase and accumulate reactive oxygen species in the presence of oxygen. Examples include clostridium, bacteroides and actinomyces.


Why is Rickettsiae an obligate intracellular bacteria?

It cannot make its own ATP


Why are asplenic patients at increased risk for meningococcal meningitis?

They cannot opsinize N. meningitides as well and the bacteria persist longer.


A patient presents with oral and facial abscesses that drain through the sinus tracts. Labs show gram positive filamentous anaerobic bacteria with sulfur granules. What is causing his condition? How do you treat him?

Actinomyces israelii. Treat with penicillin.


A sheep farmer presents with a black eschar on his arm with edema surrounding the lesion. Labs are shown below. What bacterial exotoxin is responsible for this lesion? What other presentations can be caused by this bacteria?

Edema factor from B. anthracis (boxcar-shaped gram + rod) is like adenylate cyclase, increases cAMP and causes fluid accumulation. In addition to cutaneous anthrax, inhalation of spores can cause pulmonary anthrax (fever, pulmonary hemorrhage, mediastinitis and shock) and GI anthrax (ulcers, regional, edema, hemorrhage, sepsis, 50% mortality)


A 10 year old boy presents with muscle spasticity and lock jaw a few weeks after stepping on a nail in the yard. What bacterial exotoxin is responsible for his symptoms?

Tetanospasmin from C. tetani prevents release of inhibitory neurotransmitters (GABA and glycine) from Renshaw cells in the spinal cord.


A 7 month old girl presents with flaccid paralysis after eating some honey with her sandwich. What bacterial exotoxin is responsible for her symptoms?

Botulinum toxin prevents release of excitatory neurotransmitters (ACh) from neuromuscular junctions.


A patient presents after being shot in the leg with bubbles forming around the wound. Labs show a double zone hemolytic pattern on blood agar. What bacterial exotoxin is responsible for his condition?

C. perfringes produces an alpha toxin which is a phospholipase (lecithinase) that degrades tissue and cell membranes. 


A patient presents with fever, vomiting, desquamation of the skin, rash, hypotension and shock. Symptoms resolve after a tampon was removed that had been left in for a week. Staph aureus is cultured. What toxin was mediating his symptoms?

TSST-1. This locks the CD4 and MHC II receptors together, resulting in overproduction of IFN-gamma and IL2. 


A patient presents with a skin rash. Streptococci are cultured after the patient died of septic shock. What toxin caused him to die?

Exotoxin A. This locks the CD4 and MHC II receptors together, resulting in overproduction of IFN-gamma and IL2. 


A patient presents with a fever and neck stiffness. Physical exam reveals hypotension, edema and petechiae. CSF shows gram negative diplococci in pairs. How might a toxin be causing his symptoms?

Endotoxin activates macrophages and they secrete IL-1 (fever), TNF-alpha (hypotension, fever) and NO (hypotension). It activates complement and C3a (hypotension, edema) and C5a (PMN chemotaxis) are released. It activates tissue factor, the coagulation cascade and causes DIC.


Gram positive anaerobic spore-forming rods

Clostridium. Bacillus are gram positive AEROBIC spore forming rods


A patient who was admitted to the hospital for cardiac failure develops diarrhea and abdominal cramps. Pseudomembranes are seen on flexible sigmoidoscopy. Lab analysis shows a gram positive spore forming anaerobe. How should you treat him?

He has C. difficile colitis. The bacteria secrete toxin A (binds to brush border of gut) and toxin B (disrupts cytoskeleton via actin depolymerization). Treat with oral vancomycin or metronidazole.


A patient presents with a fever and neck stiffness. Physical exam reveals hypotension, edema and petechiae. At the end of the day he is dead and autopsy shows necrotic adrenal glands. What was likely causing his condition? How could he have been treated and how should you proceed form here?

N. meningitides causes meningococcemia, meningitis and Waterhouse-Friderichsen syndrome (when the adrenals are involved). He could have been treated with ceftriaxone or penicillin G early in the infection. Close contacts should be given prophylactic rifampin, ciprofloxacin or ceftriaxone.


3 types of spirochetes? What is the only type that can be visualized with dye?

Borrelia, Leptospira and Treponema: Only Borrelia can be visualized with Giemsa-Wright staining.

An 18 year old man presents to the ED with respiratory and CNS depression, pinpoint pupils, decreased gag reflex, and seizures. After giving naloxone his symptoms improve and he is enrolled in a detox center. What medications might this center utilize to help this patient?

Methadone: occupies mu receptors for a long time, withdrawal is longer and more mild than heroin, so they will taper him off gradually. Naloxone + Buprenorphine: Buprenorphine mildly stimulates mu receptors, has fewer withdrawal symptoms than methadone and naloxone is inactivated when taken orally (prevents crushing or injecting abuse of suboxone). Naltrexone: long-acting opioid antagonist used once patient has recovered, prevents patient from getting high if relapse occurs.


A 65 year old man presents to the ED with delirium tremens, hepatitis, pancreatitis and cirrhosis. He is enrolled in a detox clinic. What medications might they use to help him overcome his alcoholism?

Disulfiram: inhibits alcohol dehydrogenase and increased acetaldehyde levels and making the patient feel really bad. Naltrexone: prevents reinforcing DA release with drinking. AA meetings to cope with psychological dependence.


Why might beer supplemented with vitamins be a good idea?

Alcoholics take in empty calories and don’t get enough vitamins. This causes Wernicke (confusion, ophthalmoplegia and ataxia) Korsakoff (irreversible memory loss, personality change and confabulations) syndrome. These syndromes are associated with periventricular hemorrhage and mammillary body necrosis due to thiamine deficiency.


Opioid receptor agonists

mu = morphine. kappa = dynorphin. delta = enkephalin.


How do opioids mediate pain analgesia?

Binding of the mu receptor results in opening of K+ channels and closing of Ca2+ channels. This results in decreased peripheral synaptic transmission by decreasing release of ACh, NE, 5HT and substance P. Centrally they block GABA neurons and potentiate DA release.


How do barbiturates mediate sedation?

They potentiate GABAa action. This increases the DURATION of Cl-channel opening and decreases signal transmission.


How do benzodiazepines mediate sedation?

They potentiate GABAa action by increasing the FREQUENCY at which the Cl channels open. This decreases signal transmission.


What is the 1st sign of shock



What types of shock are included in the category of distributive shock?

Septic, neurogenic and anaphylactic.


Compare and contrast these categories in distributive shock vs. cardiogenic shock: cardiac output, peripheral resistance, venous return, pulmonary capillary wedge pressure, temperature of extremities and use of fluids.

Twenty-four hours after placement of a catheter, a hospitalized patient develops a fever and chills. Within 1 hour her systolic blood pressure falls 30 points and she develops swelling in her extremities. Despite valiant efforts by the hospital staff, the patient dies. X-ray of the patient’s lungs taken only hours before she passed away shows pulmonary edema. What mediators of this patient’s disease process is most likely responsible for the pathology described?

This patient suffered from endotoxic shock from gram negative bacteremia. LPS activates the alternative complement cascade. C3a causes hypotension and edema, C5a causes PMN chemotaxis, Hageman factor causes DIC by activating the coagulation cascade, IL-1 causes fever and NO causes hypotension.


Postive Weil-Felix reaction may mean the patient has a proteus infection or what other type of infection due to cross-reactivity of the test?
