|
Toxocara Canis |
Roundwormof dogs Livesin the small intestine Dogsare infected transplacentally andvia transmammaryroutes Dogscan also be infected by eating infected eggs directly or by eating infectedrodents •Prepatentperiod–4-5 weeks–3 weeks in puppies infected inutero •Clinicalsigns–Abdominalpain, discomfort and pot bellies in young puppies–Vomitingor unformed feces–Cancause coughing during lung migration–Canresult in intestinal obstruction/intussusception and death Considered zoonotic |
|
Toxocara Cati |
Roundwormof cats Livesin the small intestine Catsare infected via transmammaryroute Catscan also be infected by eating infected eggs directly or by eating infectedrodents •PrepatentPeriod–6-8weeks Clinicalsigns–Abdominalpain, discomfort and pot bellies in young kittens –Cancause pneumonia in young kittens due to lung migration–Vomiting Considered zoonotic |
|
Baylisascaris procyonis |
Raccoonroundworm Livesin small intestine of raccoons, rarely infects dogs Thisdisease is zoonotic and can cause nervous system and ocular disease in humansProperhygiene and cleaning methods are needed to minimize the risk of infection. Raccoon colonies should be discouraged |
|
Ancylostoma |
Ancylostomacaninum–dog hookworm Ancylostomatubaeformae –cat hookworm Lives in the small intestine Dogs are infected via transmammaryroutes, ingestion of larva in the environment or paratenichosts, through skin penetration and possibly via transplacentalinfection. (Hypobiosis: intissue until pregnant) Cats can also be infected by skinpenetration or ingestion of larvae in the environment or in paratenichosts. Prepatentperiod–2-3 weeks Clinicalsigns –Usuallyless severe in cats–Anemiaand death in heavily infected dogs Considered zoonotic |
|
Uncinaria stenocephala |
Hookwormof both dogs and cats Similarto Ancylostomasp.but is more likely to be eaten than to penetrate skin Sometimecalled the Northern hookworm due to its tolerance of cooler temperatures. Less severe clinical signs and not considered to be zoonotic |
|
Trichuris vulpis "Nicki Minaj" |
Whipwormof dogs Livesin cecum and large intestine Dogsare infected when they eat infectious eggs Heavyinfections can cause weight loss and diarrhea•Whipwormsare not zoonotic Prepatentperiod is 11 – 12 weeks |
|
Strongyloids stercoralis "threadworm" |
Threadworm of dogs Adult female lives in smallintestine of dogs.–Only females are parasitic.–Females produce eggs by mitosis–The eggs hatch into larva in theenvironment and either become infective larva or free living adults–Larva enter the skin of host –Free living males and females mateand produce infective larva Infection is usually through skinpenetration although transmammaryinfection may occur Heavy infections can causerespiratory signs and enteritis Prepatentperiod is 8-14 days Auto-infection may be possible,especially in immunocompromisedindividuals This parasite is zoonotic and canbe fatal in humans |
|
Physaloptera "stomach worm" |

|
Aonchetheca putorii |

|
Aelurostrongylus abstrusus |
•Lungworm of cat •Cats become infected by eating slugs, snails (intermediate hosts) or rodents and amphibians (paratenic hosts) •Can cause chronic coughing, but may cause no signs at all
•Prepatent period is 5-6 weeks
Gives birth to live larvae and has s-shaped kink in tail. |
|
Crenosoma vulpis |
•A lungworm found increasingly in the red fox population and dogs of Atlanta Canada •Lives in the lungs (bronchi/bronchioles) •Eggs laid hatch as larvae which are cough, sneezed or brought to the mouth with mucus and then swallowed and passed in the feces • Larvae penetrate snails or slugs which act as an intermediate host. •The dog or fox eat infected snails or slugs and the infective larvae penetrate the intestinal wall and migrate to the lungs through the blood vessels •Detected with Baermann Technique •Prepatent period is 20 days.
Fox worm, give birth to live larvae |
|
Spirocerca lupi |
•Esophageal worm of dogs •Lives in esophagus and stomach of dogs and occasionally the aorta •Dogs are infected by eating dung beetles (intermediate host) or rodents and birds (paratenic host) •Egg is infective when passed and is eaten by a beetle •Dogs ,may have no signs at all, others may show regurgitation, and rarely more severe signs such as esophageal obstruction and rupture and signs of heart disease can occur •Prepatent period is 5-6 months •This parasite has been linked to the development of sarcomas
|
|
Ollulanus tricuspus |
•Stomach worm of cats •Lives in the stomach •Cats are infected when they eat infective larvae vomited up by other cats. •Larva mature inside the host, not in the environment. •Infection causes vomiting •Prepatent period is 33 -37 days
