Trichuris Vulpis


Presentation

  • We present a human infection with the canine whipworm, Trichuris vulpis, in a child suffering from rhinitis with a diagnosis of rhinitis.[ncbi.nlm.nih.gov]
  • Few species of trees are present; these are primarily conifers that grow in dense stands with little undergrowth.[animaldiversity.org]
  • In the rare cases that T. vulpis infects humans, it can cause visceral larva migrans (VLM) which presents as eosinophilia, hepatomegaly, and pulmonary symptoms.[en.wikipedia.org]
Asymptomatic
  • Both patients were almost asymptomatic. The diagnosis of visceral larva migrans was based on the results of immunoelectrophoretic studies and no liver biopsy was performed.[ncbi.nlm.nih.gov]
  • Trichuris vulpis Prepatent period Trichuris vulpis Site of infection Adults in large intestine, particularly cecum Trichuris vulpis Pathogenesis and lesions Many infections are light and asymptomatic. Symptoms seen if large numbers.[quizlet.com]
  • Infections may be asymptomatic or may involve diarrhea, nausea, and abdominal pain. 3, record 1, English, - canine%20whipworm Record 1, Key term(s) canine whip-worm Record 1, French Record 1, Domaine(s) Vers et organismes apparentés Maladies des animaux[btb.termiumplus.gc.ca]
Pain
  • Both of them had nonspecific abdominal pain and one had episodes of diarrhea. Clinical recovery was good after treatment with mebendazole.[ncbi.nlm.nih.gov]

Inflammation
  • Large numbers cause diptheritic ("leather" like character) inflammation of the cecal mucosa Trichuris vulpis Clinical signs Sporadic diseases due to heavy infections are common in dogs and associated with watery bloody diarrhea Trichuris vulpis Diagnosis[quizlet.com]
Rhinitis
  • We present a human infection with the canine whipworm, Trichuris vulpis, in a child suffering from rhinitis with a diagnosis of rhinitis.[ncbi.nlm.nih.gov]
Larva Migrans
  • The diagnosis of visceral larva migrans was based on the results of immunoelectrophoretic studies and no liver biopsy was performed.[ncbi.nlm.nih.gov]
  • Chronic eosinophilia due to visceral larva migrans; report of three cases. Pediatrics. 1952 Jan; 9 (1):7–19. [ PubMed ] [ Google Scholar ] Mok CH. Visceral larva migrans. A discussion based on review of the literature.[ncbi.nlm.nih.gov]
  • Visceral larva migrans caused by Trichuris vulpis. Abstract Two brothers with visceral larva migrans caused by Trichuris vulpis were diagnosed after they had been investigated for an eosinophilia. Both patients were almost asymptomatic.[adc.bmj.com]
Ulcer
  • We report a case of human infection with the whipworm of dogs, Trichuris vulpis, in a woman with duodenal ulcer disease, chronic diarrhea, and close contact with dogs.[ncbi.nlm.nih.gov]
  • It has been hypothesized that various other immunological disorders observed in humans, such as Crohn's Disease, inflammatory bowel disease, food allergies, multiple sclerosis, and ulcerative colitis may be treated with intentional infection with helminths[animaldiversity.org]
Suggestibility
  • As the name suggests, the worm has a whip-like shape with distinct features including a small, narrow anterior head, which is the digestive part of the worm, and a larger posterior tail, which is the reproductive part of the worm.[en.wikipedia.org]
  • There have been studies that indicate a suppressed immune response to antirabies vaccination in infected puppies, suggesting that more vaccines are needed for the individual to achieve the desired level of resistance.[animaldiversity.org]

Toxocara Canis
  • Prevalence of hookworms (28.1%), Toxocara canis (11.8%), and Trichuris vulpis (3.5%) was found in 292 fecal samples of dogs collected at the peri-domicile, which showed that the risk of infection was not only fortuitous.[ncbi.nlm.nih.gov]

Treatment

  • Clinical recovery was good after treatment with mebendazole.[ncbi.nlm.nih.gov]
  • The treatment of canine whipworm infections is similar to that of T. trichiura infection. We recommend differentiation of the 2 species for their epidemiological and prevention implications.[ncbi.nlm.nih.gov]
  • Dogs require re-treatment monthly for 3 treatments due to the long prepatent period of this parasite.There are also monthly preventive treatments that can be used. These are usually one of the above drugs combined with a heartworm prevention drug.[en.wikipedia.org]
  • Treatment using HPP has been shown to be effective in inactivating nematode larvae in food and preventing embryonation of Ascaris suum eggs.[pubag.nal.usda.gov]
