Respiratory Pathology Flashcards
What type of epithelium lines the oral cavity?

stratified squamous epithelium
What type of epithelium lines the nasal cavity?

resp epithelium (stratified columnar ciliated/goblet cell) inside nose is stratified squamous
Which type of pneumocyte more susceptible to injury?

type 1
How do pneumocytes respond to injury?

type 2 pneumocytes less susceptible to injury because when the type 1s are injured the type 2s can transform into type 1 to help the lung repair
True or false
There is normal flora found in all aspects of the respiratory system.
false
normal flora restricted to the proximal region of the conductive system (nasal cavity, nasopharynx, larynx, trachea. not the distal resiratory tract (STERILE)
Potentially pathogenic normal flora in cattle
Mannheimia haemolytica
Potentially pathogenic normal flora of pigs and dogs
Bordetella bronchiseptica
true or false
These are specific defense mechanisms of the respiratory system

false
nonspecific (non-immune mediated)
What are the specific (immune mediated) defense mechanisms of the respiratory system

PAMs and PIMs (intravascular) clear the lungs of what species
rums
not dogs/humans/lab animals they have Kupffer cells(liver) and splenic macrophages
What is the black ?

hydrolytic enzymes
What are the 3 main causes of epistaxis in horses?
- ethmoidal hematoma
- exercise induced pulmonary hemorrhage (race horses)
- mycotic infxn of the gutteral pouch
Nose bleed of older horse

ethmoidal hematoma
What is this in older horses and why does it happen?

Pedunculated tumor-like lesion in older horses. The exact etiology of this lesion is unknown.
This fibrinous rhinitis is caused by what dz in calves?

IBR
What is teh etiology

IBR
This is caused by the eggs of Oestrus ovis

false the larva
Oestrus ovis larva trapped in the brain cause what type of inflammation

encephalitis
The top left is normal and the other three are varying degrees of ____?

atrophic rhinitis in pigs
The toxins of Bordatella bronchiseptica and Pasturella multocida types D/A do what to bone cells?
inhib osteoblasts (decrease bone prod)
stim osteoclasts (increase bone break)
Where do you make PM cut in a pig with atrophic rhinitis
between premolar 1-2
in a pig

atrophic rhinitis
_______ of the_____ nasal turbinate is the area most commonly and consistently affected

The ventral scroll of the ventral nasal ……
Nasal submucosal glands with large basophilic Intranuclear inclusions

Inclusion Body Rhinitis – Porcine Cytomegalovirus (suid herpesvirus 2 [SHV-2]) infection, Pig, AVC, OI Usually in pigs 3-5 weeks of age. Fatal systemic infection occurs occasionally in younger suckling pigs (less than 3 weeks of age)
