CSF and Blood
This anticoagulant is used in blood culture bottles to prevent clotting
SPS
This drug is used to detect MRSA via disk diffusion
Cefoxitin
The cause of Black Eschar Lesion
Bacillus anthracis
Give the bacteria's name AND the disease name
Treponema pallidum, Syphillis
This is the sputum rejection criteria.
>25 Epi's and <25 WBC's
CSF Results:
Protein = normal; Glucose = normal
Cell count: 1500 mononuclear cells/hpf
Differential: 100% lymphocytes
Direct smear: No organisms seen, Moderate WBC's
What is your interpretation of this result?
Viral meningitis
A urine sample was plated to a blood and Mac with a 1uL loop and is growing a pure culture with 60 colonies present on the plate. How many CFU's does this represent?
60K (60,000) CFU/mL
These two organisms can be implicated in Toxic Shock Syndrome.
Streptococcus pyogenes (GAS)
Staphylococcus aureus
This organism causes sterile pyuria (no growth in culture, but >10 white cells/lpf).
It commonly coinfects with this organism.
Chlamydia trachomatis
Neisseria gonorrhoeae
This viral cause of pneumonia can be treated with antivirals to lessen severe symptoms if used within 48 hours.
Influenza
Resin Beads serve this purpose in blood culture bottles.
Absorb antibiotics
This is the beta lactamase inhibitor used in combination with cephalosporins to detect ESBL in the disk diffusion test.
Clavulanic acid
This organism can be the cause of bite wound infections from both animals and humans.
Capnocytophaga
This organism plays a crucial role in preventing the overgrowth of pathogens that cause Bacterial Vaginosis
Lactobacillus
A college student presents with what her physician terms “atypical pneumonia” after viewing her chest x-ray. This community acquired pathogen is usually associated with this description.
Mycoplasma pneumoniae
This is the blood to broth ratio for blood culture bottles.
1:5-1:10
A urine culture grows 100,000 CFU/mL of a catalase-positive, coagulase-negative, novobiocin-resistant gram-positive cocci. What is the most likely pathogen?
Staphylococcus saprophyticus
This organism genus should be suspected in coastal water wound infections like coral reef abrasions.
This media would be used to isolate this group.
Vibrio
TCBS
These two organisms invade the full thickness of the intestinal wall and spread via lymphatics, often causing severe diarrhea.
Yersinia enterocolitica
Salmonella typhi
Bronchiolitis in an 18 month old, often requiring hospitalization for wheezing and difficulty breathing is most often caused by this.
RSV
These 3 pathogens are the most common isolates in CSF samples in neonates.
Group B Strep
Gram negative bacilli
Listeria
This is the mode of action of macrolides, aminoglycosides, and tetracycline
Protein synthesis (ribosome target)
A burn patient’s wound shows 2 colony types:
1) White, beta-hemolytic, GPCCL
2) Flat, spready, sheeny, beta-hemolytic, NLF
Name these two likely pathogens
Staphylococcus aureus
Pseudomonas aeruginosa
This virus is implicated in cervical cancer and can be vaccinated for as a young adult
HPV
These three organisms are the most common causative agents of otitis media.
Streptococcus pneumoniae
Haemophilus influenzae
Moraxella catarrhalis
