Strep suis and Glasser's Disease (H. parasuis)

Question 1

Etiology of Strep Suis:

Answer 1

Streptoccocus suis type II

Question 2

Strep suis is a very common post-______ infection.

Answer 2

Post-weaning

Question 3

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

Answer 3

True

Question 4

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

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

Answer 4

Pneumonia, polyserositis

Question 5

Neurological clinical signs of Strep suis:

Answer 5

Incoordination, stupor, convulsions, dypsnea, wasting

Question 6

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

Answer 6

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.

Question 7

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

Answer 7

variably

Question 8

Is Strep suis potentially zoonotic?

Answer 8

Yes

Question 9

Etiology of Glasser’s Disease

Answer 9

Haemophilus parasuis

Question 10

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

Answer 10

early, weaning

Question 11

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

Answer 11

serositis

Question 12

Clinical signs of Glasser’s disease:

Answer 12

Neurologic signs, dyspnea, and wasting

Question 13

Prevention and control for Glasser’s Disease includes:

Answer 13

vaccination, and antibiotics; however vaccines are not completely effective

Question 14

Three primary rule-outs of polyserositis:

Answer 14

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

Question 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?

Answer 15

No

Question 16

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

Answer 16

Brain

Question 17

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

Answer 17

purulent; PMNs

Question 18

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

Answer 18

lymphocytic, lymphocyte

Question 19

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

Question 20

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

Answer 20

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

Question 21

Fibrin is always inflammatory sign. True or False.

Answer 21

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