Nasal mite and respiratory parasites

Question 1

Pneumonyssoides caninum

Answer 1

Rare, small, white, life cycle entirely within host, direct contact spreads mites. Irritation of the mucous membranes, sneezing, rhinitis

Question 2

How do you treat pneumonyssoides caninum?

Answer 2

None approved- use imdacloprid/moxidectin, selamectin, milbemycin oxime

Question 3

What is the parasite associated with nasal capillariasis?

Answer 3

Eucoleus boehmi

Question 4

Eucoleus boehmi

Answer 4

White, thin worms in mucosal epithelium of nasal turbinates, frontal and paranasal sinuses, can have earthworms as IH, can see sneezing and discharge

Question 5

What is the treatment for Eucoleus boehmi?

Answer 5

None approved, use ivermectin or fenbendazole

Question 6

Eucoleus aerophilus

Answer 6

in trachea, bronchi, and bronchioles, slender white worms, direct life cycle but can use earthworms as PH, infective larvated eggs swallowed–>lungs–>mature in bronchioles and alveoli–>eggs coughed up and swallowed; severe bronchopneumonia and secondary pneumonia can occur, find eggs in feces

Question 7

How do you treat Eucoleus aerophilus?

Answer 7

None approved, use fenbendazole or ivermectin

Question 8

Filaroides osleri

Answer 8

Junction of trachea and primary bronchi–>deposit thin shelled eggs–>L1 hatch and are carried to the trachea and swallowed–>passed in feces or vomit and are immediately infective–>lungs where develop to adults in nodules. Can infect pups through cleaning, or by autoinfection. most severe in puppies. Sedimentation best to get larvae

Question 9

What is the treatment for F. osleri?

Answer 9

Three criteria for successful chemotherapy:

1) disappearance of signs 2) resolution of nodules 3) disappearance of larvae from feces

Question 10

Aelurostrongylus abstrusus

Answer 10

cats-bronchioles and alveolar ducts, male bursa with short indistinct lobes. Eggs in b/ad–>larvae hatch and are moved up by mucociliary action, passed in feces, goes into snail or slug, cat eats IH, PPP 5-6 weeks. Produce inflammatory exudates, atalectasis, granulomatous pneumonia. Use Baermann procedure~

Question 11

Crenosoma vulpis

Answer 11

dogs-bronchi and bronchioles, slender and tapered at both ends, cuticle like folds. Use Baermann procedure for larvae recovery

Question 12

How do you treat A. a?

Answer 12

None approved, use imidacloprid/moxidectin

Question 13

Paragonimus kelicotti

Answer 13

Thick oval fluke with spiny cuticle, eggs coughed up and swallowed–>feces–>miracidium to snail–>cercariae leave and penetrate crawfish–>encyst as metacercariae–>excyst in DH–>penetrate abdominal cavity to lungs. Results in eosoniphilic granulomatous pneumonia LIKE H. americana. Signs are moist cough, chronic gagging, coughing up blood

Question 14

How do you treat P. kellicotti?

Answer 14

None approved, use fenben or praziquaantel (like al flukes)

Question 15

Is P. kellicotti zoonotic?

Answer 15

Yes but only if eat undercooked crayfish

Question 16

Linguatula

Answer 16

Respiratory passages of canids, pentastomid (four legged larvae in eggs), need herbivore for IH, dog eats viscera, need to be physically removed from host
