Strep suis and Glasser's Disease (H. parasuis) Flashcards
Etiology of Strep Suis:
Streptoccocus suis type II
Strep suis is a very common post-______ infection.
Post-weaning
In strep suis, infection is more common than neurologic disease. True or False.
True
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
Neurological clinical signs of Strep suis:
Incoordination, stupor, convulsions, dypsnea, wasting
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.
Vaccination and antibiotics are _____ effective in for treating Strep suis.
variably
Is Strep suis potentially zoonotic?
Yes
Etiology of Glasser’s Disease
Haemophilus parasuis
Haemophilus parasuis is an _____ colonizer, and therefore a common infection in post-______ pigs.
early, weaning
Glasser’s disease is associated with penumonia, poly-______, and other signs of septicemia.
serositis
Clinical signs of Glasser’s disease:
Neurologic signs, dyspnea, and wasting
Prevention and control for Glasser’s Disease includes:
vaccination, and antibiotics; however vaccines are not completely effective
Three primary rule-outs of polyserositis:
- Glasser’s disease (H. parasuis)
- Mycoplasmal polyserositis (M. hyorhinis)
- Mulberry heart disease
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
Both Strep suis and H. parasuis can localize in the ____ and cause meningitis.
Brain
Strep, and H. parasuis results in ____ inflammation, hence ____ are predominant WBC.
purulent; PMNs
Myocplasma hyorhinis results in _____ inflammation, therefore the _____ is the common WBC.
lymphocytic, lymphocyte
Mycoplasma hyorhinis tends to produce more _____ inflammation, than neutrophilic infalmmation caused by Strep and H. parasuis.
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.
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
