Anaerobes
Honey
I say autoinfection, you say (which parasite?):
Ascaris lumbricoides
Serpentine cording on plate/smears indicates which species of mycobacteria
M. tuberculosis
Positive germ tube
Candida albicans
A blood smear shows the following characteristics:
Banana shaped gametocytes
Multiple Ring Form inside RBC's
40% RBCs are infected
Diagnosis?
P. falciparum
An organism that requires an anaerobic environment to survive (ie-oxygen in any amount will kill) is defined as a:
Strict Anaerobe
That undercooked pork I ate gave me a soft tissue and brain infection- the doctor called it cysticercosis. Which parasite should I blame?
Taenia solium
Name the vaccine used throughout the world (except here in the US) for tuberculosis
BCG vaccine
If I suspect a dimorphic fungus from a patient mold sample at 30 degrees C, what could I do to prove it?
Grow the mold at 37 C to see if it converts to a yeast!
A 3 year old child presents with severe diarrhea for 5 days (it's going around town!). The acid fast smear is positive for oocysts. Diagnosis?
Cryptosporidium
An anaerobic brucella plate with a double zone of beta hemolysis should have a gram stain showing what (yes it was proven to be a true anaerobe):
Large boxcar GPR, may be decolorizing
Paragonimiasis is diagnosed from which clinical specimen
Sputum
Which species of mycobacteria is NON CULTURABLE and requires skin scraping microscopy for diagnosis
M. leprae
Inhaling just a few arthroconidia of this dimorph can lead to a dangerous systemic mycoses- even in a health patient!
Coccidioides immitis
HIV positive patient presents with meningitis symptoms. A spinal fluid was collected and examined for pathogens. A budding encapsulated yeast was recovered. Diagnosis?
Cryptococcus neoformans
This is the media of choice to select for anaerobic gram negative rods only
This schistosome infects the bladder (bloody urine is one of the symptoms)
S. haematobium
Using this reagent during mycobacteria sputum digestion/decontamination will get rid of Pseudomonas aeruginosa
Oxalic acid
An LPCB prep shows sporangium that terminate at rhizoids. This fungus grew in 3 days and was a "lid lifter". What fungus are you looking at?
Rhizopus
A 29-year-old female patient presented to her primary care physician reporting a 15-day history of whitish, vaginal discharge associated with itching. She also complained of lower abdominal pain. A vaginal, speculum examination revealed an inflamed cervix with red, punctate lesions. Patient admits to having multiple sexual partners.
Diagnosis?
Trichomonas vaginalis
Impaired speech
Difficulty swallowing
Weakness
Flaccid paralysis
The only clinically significant ciliate... (oink oink)
Balantidium coli
The two drugs that are used to treat non resistant MTB?
Rifampin and Isoniazid
This dimorphic fungus is one of the only that causes a subcutaneous mycoses. LPCB prep shows rosette conidia.
Sporothrix schenkii
A 27 year old oceanographer sustains an abrasion on his left thigh. A culture of this wound grew an acid fast organism at 30 degrees C. Diagnosis?
M. marinum
