Salmonella, campylobacter, parvo
What are 3 characteristics of Salmonella?
Blood diarrhea, gastroenteritis, septic shock
What are 3 characteristics of Campylobacter?
Large bowel diarrhea (mucous), bloody diarrhea, asymptomatic carriers
How do you diagnose Campylobacter?
Culture feces with a special medium; very tiny darting seagull like organisms
What 3 organisms are spirochetes?
Helicobacter, Lepto, Lyme
What is the main characteristic of helicobacter?
Chronic gastric ulcers
How do you diagnose Helicobacter?
brush cytology of gastric mucosa
How do you treat Helicobacter?
Triple therapy: Amoxicillin, metronidazole, H2 blocker
This organism is found in the oral cavity and often involves draining wounds and bone
Actinomyces
This organism is associated with wounds/pyothorax and involves the respiratory tract especially in cats…it can be diagnosed using an acid fast stain
Nocardia
Which organism is slow growing so you must hold the culture for 10 days before making a diagnosis
Nocardia
This organism lives intracellular, gives rise to bacteremia and causes ocular, neuro and repro problems
Brucella
This organism can have positive titers up to 3 years and causes abortions; Euthanasia is recommended to its chronic zoonotic potential
Brucella
OspA is located in the _______while OspC is located in the _______
Gut; saliva
This bacteria causes polyarthritis (shifting lameness) and nephropathy
Borrelia Burgdorferi
How many hours post attachment until an animal can be infected with Borrelia Burgdorferi?
48 hrs
How many months until you will see clinical signs in an animal infected with Borrelia Burgdorferi?
2-5 months
What will a biochem reveal if Lyme dz is present?
neutropenia and increase globulins
A dog tests positive on a C6 Ab Snap Test…does this predict disease?
No only exposure and infection
When would you treat Lyme dz?
If C6 positive + showing clinical signs
Would you treat a lyme case that was C6 positive and showed proteinuria?
yes
What is the treatment of choice for Lyme?
Doxy
T/F Blood is a good specimen for detecting Lyme while synovial tissue is the worst
FALSE; synovial tissue is the best choice
Renal and hepatic failure along with vasculitis (thrombocytopenia, neutropenia, anemia) is common with what dz?
Lepto
T/F Lepto is shed in the urine and is highly zoonotic
TRUE
If a dog presents with increase hepatic and renal enzymes and is acutely sick what bacteria is it most likely infected with?
Lepto
T/F PCR is a good choice for Lepto since it is in the blood
TRUE; submit blood and urine
T/F A sero of 1:3200 = dz while 1:800 = maybe dz
TRUE
The carrier state of lepto is located in what organ?
Renal endo cells
What 2 dz’s if giving vaccines do you want to start at 12 wks instead of 8? Why?
Lyme and Lepto because there will be fewer maternal Abs present
Sardonic, trismus, dysphagia, saw horse stance are all signs of infection with what bacteria?
Clostridium tetani
T/F Clostridium Tetani likes an aerobic environment
FALSE; anaerobic
Unless a dog has had its spleen removed or is immunocompromised there will be no signs of hemolytic anemia associated with this bacteria
Mycoplasma hemocanis
