Flashcards in Strep suis and Glasser's Disease (H. parasuis) Deck (21):
1

Etiology of Strep Suis:

Streptoccocus suis type II

2

Strep suis is a very common post-______ infection. 

Post-weaning

3

In strep suis, infection is more common than neurologic disease. True or False.

True

4

Strep suis is a respriatory pathogen, and may be associated with: __________

It is also a septicemic organism, and can be associated with septicemia.

Pneumonia, polyserositis 

5

Neurological clinical signs of Strep suis:

Incoordination, stupor, convulsions, dypsnea, wasting

6

Strep suis can be controlled by segregated early weaning. True or False.

False!!!! Strep suis are very early colonizers! Piglets may get it as they pass through vaginal tract when born, and colostrum immunity does not help prevent form colonizing.

7

Vaccination and antibiotics are _____ effective in for treating Strep suis.

variably 

8

Is Strep suis potentially zoonotic?

Yes

9

Etiology of Glasser's Disease

Haemophilus parasuis

10

Haemophilus parasuis is an _____ colonizer, and therefore a common infection in post-______ pigs.

early, weaning

11

Glasser's disease is associated with penumonia, poly-______, and other signs of septicemia.

serositis

12

Clinical signs of Glasser's disease:

Neurologic signs, dyspnea, and wasting

13

Prevention and control for Glasser's Disease includes:

vaccination, and antibiotics; however vaccines are not completely effective

14

Three primary rule-outs of polyserositis:

  • Glasser's disease (H. parasuis)
  • Mycoplasmal polyserositis (M. hyorhinis)
  • Mulberry heart disease

15

Mulberry heart disease presents as polyserositis - with acute myocardial necrosis and HF due to selenium difficiency. Is there inflammation associated with mulberry heart disease?

No

16

Both Strep suis and H. parasuis can localize in the ____ and cause meningitis.

Brain

17

Strep, and H. parasuis results in ____ inflammation, hence ____ are predominant WBC.

purulent; PMNs

18

Myocplasma hyorhinis results in _____ inflammation, therefore the _____ is the common WBC.

lymphocytic, lymphocyte

19

Mycoplasma hyorhinis tends to produce more _____ inflammation, than neutrophilic infalmmation caused by Strep and H. parasuis.

20

Mulberry heart disease produces fibrin in chest cavity and pericardium due to:

  • HF - causing back up pressure/congestion
  • When you get leakage - effusion, transudate
  • Fibrinogen is in the effusion, and when it polymerizes, causes fibrin.

21

Fibrin is always inflammatory sign. True or False.

False, it can be the result of inflammation, but also can be due to evidence of transudate with excess fibrinogen leaking out of places
