| Trichuris spp. Distribution Course in body Definitive Host Life Cycle Clinical Signs Diagnosis Treatment Zoonotic? | Whipworms Worldwide Small intestine to cecum Mammals Direct Cycle: Egg passed in feces, infective larvae develop in egg in environment,dog ingests egg, mature in large intestine, fix in mucosa. Clinical signs: Hemorrhagic typhlitis, colitis, bloody diarrhea, weight loss, dehydration. Diagnosis: Fecal float, antigen, ID adults Treatment: Some heartworm preventions, fenbendazole/febantel, macrocyclic lactones, fenbendazole, dichlorvos, prompt removal of feces, routine deworming Zoonotic |
| Capillarids Distribution Course in body Definitive Host Treatment Zoonotic? | Hairworms Worldwide Varies Mammals Treatment: fenbendazole, ivermectin, topical imidacloprid/moxidectin in cats, prevent predation Zoonotic |
| Eucoleus spp. Course in body Definitive Host Life Cycle Clinical Signs Diagnosis | Capillarid Gi tract to respiratory tract Canine/Feline (E. aerophilus), Canine (E. boehmi) Direct cycle: Egg passed in feces, embryonates, eaten by host, hatch in small intestine, migrate to respiratory tract Clinical signs: Bronchitis/tracheitis, cough, dyspnea, anorexia, nasal discharge, sneezing Diagnosis: Fecal float |
| Pearsonema spp. Course in body Definitive Host Life Cycle Clinical Signs Diagnosis | Capillarid GI tract to urinary tract Dogs/Cats(P. plica), Cats(P.feliscati) Indirect cycle: Egg passed in feces, embryonates, eaten by earthworm, eaten by host, hatch in small intestine, migrate to urinary tract Clinical signs: Cystitis Diagnosis: Urine sediment |
| Aonchotheca spp. Course in body Definitive Host Life Cycle Clinical Signs Diagnosis | Capillarid GI tract Cats, swine, ruminants Direct cycle: Egg passed in feces, embryonates, eaten by host, hatch in small intestine, migrate to stomach/small intestine Clinical signs: Gastritis Diagnosis: Fecal Float |
| Dioctophyme renale Distribution Course in body Definitive Host Life Cycle Clinical Signs Diagnosis Treatment Zoonotic? | Giant Kidney Worm Worldwide Stomach to liver to kidney (sometimes abdomen) Carnivores Indirect cycle: Unembryonated egg in urine, embryonate in water, ingested by earthworm, eaten by intermediate or definitive host, stomach-liver-kidney. Clinical signs: Pressure necrosis of right kidney, hypertrophy of left kidney, dysuria, hematuria, lumbar pain, peritonitis, hemoperitoneum from abdominal infection, vomiting. Diagnosis: Incidental during surgery, urine sediment, rads or ultrasound Treament: surgical removal of worm and kidney, prevent predation Zoonotic |
