Microbiology Cscp Pathology

Front 1

Markers of suppurative (acute) inflammation

Back 1

Leukocyte infiltration mainly by neutrophils (PMNs)

Front 2

Mononuclear and Granulomatous inflammation is mostly in response to

what type of infection evokes it?

Back 2

Viruses, intracellular bacteria, and intracellular parasites

usually evoked by slowly dividing organisms in presence of T cell mediated response

Front 3

Cytopathic and cytoproliferative inflammation is usually in response to

Back 3

Virus mediated damage

Front 4

Necrotizing Inflammation is usually mediated by ____ with what kind of immune response?

Back 4

toxins that cause severe tissue damage and cell death (Clostridium, Group A Strep)

few inflammatory cells invovled

Front 5

An auramine-rhodamine stain is used for

Back 5

Mycobacteria species

Front 6

An immnoflurorescent stain is typically used for

Back 6

Legionella

Front 7

Causative agent that grows on buffered charcoal yeast agar

Back 7

Legionella pneumophila

does better w cysteine in agar too

Front 8

What is the histopathology of a Legionella infection

Back 8

acute fibrin-purulent exudate w neutrophils and macrophages

Front 9

No white blood cells the inflammation is likely

Back 9

Necrotizing

Front 10

Beta Hemolytic and PYR positive is likely what organism

Back 10

S. pyogenes

Front 11

Type of stain for chlamydia trachomatis

diagnose by

Back 11

use an immunoflurorescent stain bc it has intracellular elementary bodies

diagnose by a amplification test

Front 12

KOH-Calcuofluor white is used to

Back 12

visualize fungus samples

KOH dissolves tissue, Calcuofluor binds to chitin of cell wall to fluroresce under UV light

Front 13

Gomori's methenamine silver and periodic acid-shiff reaction are used for

Back 13

fungal stains to detect hyphae and yeast cells

Front 14

Zygomycetes and aspergillus typically cause what type of inflammation

Back 14

acute inflammation
can invade essels causing thrombosis and necrosis

Front 15

What type of hyphae does Aspergillus have

Back 15

septated

Front 16

The rapid test for influenza A/B is what kind of test

Back 16

Enzyme immuno Assay

Front 17

A tissue exam of RSV would show what cytopathic effect

Back 17

giant cells with intracytoplasmic inclusion

Front 18

CMV produces this characteristic feature in tissue cultures

Back 18

intranuclear inclusions surrounded by clear halos

Front 19

For detection of parasites in blood this stain is used

Back 19

Wright Giemsa stain

Front 20

Chronic active duodenitis with intraepithelial lymphocytes

Examination of stool shows organism with two large nuclei and flagella

It is likely what infection

Back 20

Giardia lamblia

Front 21

2 most common parasites that cause diarrhea

Back 21

Cryptosporidium parvum
Giardia lamblia

Front 22

What stain visualizes Cryptosporidium and is used to differentiate from a Giardia infection

Back 22

Acid fast

also differentiate based on size (Giardia is bigger)

Front 23

How does Babesia look different from malaria in blood smear?

Back 23

Bebesia is a "Maltese Cross" (its by a tick bite)

Malaria in RBCs looks like rings
As a gametocyte is looks like a banana

Front 24

Presence of mecA gene in S aureus suggests what resistance

Back 24

oxacillin resistance

report as resistant to all beta lactams

Front 25

MIC can be defined as

Back 25

lowest antibiotic concentration required to visually inhibit bacterial growth

Front 26

A Kirby-Bauer disc is used for

Back 26

MIC testing, its a diffusion method
