L13: Emerging Resp. Pathogen In Dogs (Crawford) Flashcards
Bacteria included in CIRD
Bordetella bronchiseptica
Mycoplasma cynos
Strep zooepidemicus
No good Ag or Ab tests for respiratory pathogens
:)
Best diagnostic testing option for resp. Pathogens
PCR
- detects pathogen’s DNA
- very sensitive and specific
- rapid 3-5 day turnaround, allowing for timely patient and population management
CIRD PCR panel from Antech involves:
- Parainfluenza virus
- Adenovirus type 2
- distemper
- H3N8 flu virus
- Resp. Coronavirus
- Herpesvirus
- Bordetella
- Mycoplasma cynos
- Strep zoo

Most important step in managing disease outbreak
Isolation (reduces pathogen load where other animals are)
Steps in management of outbreak pending a diagnosis***
Isolation
Strict biosecurity by animal care staff
Quarantine of exposed asymptomatic dogs
Create a clean break: prevent infection of new dogs, implement steps to prevent infection of unexposed dogs
Length of quarantine time
At least as long as the incubation period
Length of isolation time based on***
Shedding period
Canine pneumovirus clinical dz
-causes an explosive increase in the number of coughing dogs w/n a short time period (
Incubation and shedding period of canine pneumovirus
Incubation:
Strep zoo
- Gram + Lancefield Group C bacterium
- causes cough/purulent nasal d/c initially, then resp. Distress, hemorrhagic nasal d/c, hemorrhagic pneumonia, and death
- has zoonotic potential
- sensitive to penicillins and cephalosporins
Viruses included in CIRD
Parainfluenza virus (CPiV) Adenovirus type 2 (CAV) Distemper virus (CDV) Herpes virus (CHV) Influenza virus H3N8 (CIV H3N8) Influenza virus H3N2 (CIV H3N2) Respiratory Coronavirus (CRCoV) Pneumovirus (CnPnV)
