Questions and Answers

Importance

Physaloptera rara = Infrequently causes gastric mucosal erosion and gastritis; adults attach with mouth parts. Spirocerca lupi = May predispose to malignant tumors and dystrophic pulmonary osteoarthropathy. Eucoleus (capillaria) aerophilus = Often confused with Trichuris sp. Thelazia californiensis = May cause conjunctivitis, lacrimation, photophobia

Diagnosis

Physaloptera rara = Larvated eggs fecal flotation or worms in vomitus. Spirocerca lupi = Eggs in feces in patent infections Ollulanus tricuspis = Baermann technique using vomitus may be useful, but diagnosis can be done by biopsy, endoscopy Strongyloides stercoralis = Worm in direct smear, straight tail

Diagnosis

Eucoleus (capillaria) aerophilus = Identifying the eggs found in fecal flotation Filaroides hirthi/osleri = Seeing larvae in feces and/or saliva/vomitus Thelazia californiensis = Eggs in lachrymal secretions. Parasites can be seen in conjunctival sac. Aelurostrongylus abstrusus = Identify larvae in direct smear, fecal flotation, Baermann technique. S shaped bend and dorsal spine

Transmission ??

<p>Aelurostrongylus abstrusus = Ingestion of snails or the paratenic host (mice/bird) Strongyloides stercoralis = Infections is generally through penetration, can also be transmammary Eucoleus (Capillaria) aerophilus = Ingestion of earthworms Filaroides hirthi/osleri = Direct lifecycle. Easily transmitted especially in kennel situations</p> Signup and view all the answers

Transmission

<p>Ollulanos tricuspis = Ingestion of larvae from infected host (i.e., another cat) Spirocerca lupi = Ingestion of dung beetle Physaloptera rara = Ingestion of roach, cricket, beetles</p> <ul> <li>= -</li> </ul> Signup and view all the answers

Treatment

<p>Ollulanos tricuspis = Fenbendazole Thelazia californiensis = Surgical removal of worms from the conjunctival sac under local anesthesia</p> <ul> <li>= - Physaloptera rara = Pyrantel pamoate every 2 weeks for at least 3 treatments</li> </ul> Signup and view all the answers

Common names??

<p>Filaroides hirthi/osleri = Canine lung parasite Eucoleus (capillaria) aerophilus = Nematode of respiratory tract Thelazia californiensis = Eye worm Aelurostrongylus abstrusus = Nematode of respiratory tract • Lung Parasite of cats</p> Signup and view all the answers

Common names??

<p>Strongyloides stercoralis = Nematode of GI tract Ollulanos tricuspis = Feline stomach worm • Rarely dogs Spirocerca lupi = Esophageal worm (spiruroidea) Physaloptera rara = Stomach worm (spiruroidea)</p> Signup and view all the answers

Pathology

<p>Physaloptera rara = chronic vomiting, gastritis Ollulanos tricuspis = chronic vomiting (especially after meals), gastritis, weight loss Aelurostrongylus abstrusus = coughing dyspnea</p> <ul> <li>= -</li> </ul> Signup and view all the answers

Location?

<p>Eucoleus (Capillaria) aerophilus = Found in the trachea and bronchi of canines and felines Strongyloides stercoralis = Lives in the small intestines dogs (can be seen in cats) Ollulanos tricuspis = Stomach, can live in vomitus up to 12 days</p> <ul> <li>= -</li> </ul> Signup and view all the answers

Random

<p>Eucoleus (Capillaria) aerophilus = Eggs are smaller, rounder, and lighter in color than Trichuris Aelurostrongylus abstrusus = S shaped bend and dorsal spine Strongyloides stercoralis = Free living, parasitic males do not exist, need to make sure fecal sample is fresh Ollulanos tricuspis = Prepatent period 33-35 days</p> Signup and view all the answers
