SEVERE WHIPWORM (TRICHURISSPP.) INFECTION IN THE DROMEDARY (CAMELUS DROMEDARIUS)

Abstract

One adult (13-yr-old) and two young (3-4-yr-old) male dromedary camels (Camelus dromedarius) from the Seoul Zoo displayed anorexia and chronic diarrhea for 2 wk. Direct fecal smear examination revealed Trichuris spp. infection. After confirmation of the infection, fenbendazole was orally administered as a suspension; this was repeated two times at 3-wk intervals. A high initial dose (20 mg/kg) was followed by administration at the recommended dose (10 mg/kg). Starting on the day following the first treatment, a large number of adult whipworms were discharged with the feces over a 3-day period. Two young male dromedary camels gradually recovered. However, the adult male dromedary camel developed continuous bloody mucoid diarrhea and died 2 days after treatment. Postmortem examination revealed that numerous whipworms were attached to the mucosa throughout the large intestine.

Fatal Cowdriosis (Heartwater) and Trichurosis in a Camel Bull (Camelus dromedarius): a case report

“…are significant parasites of camelids, and are resistant to treatment with the usual doses of anthelmintics which are effective for other GI nematodes. Fatal Trichurosis has been reported by Eo et al 2014 in Seoul Zoo with adult worms found attached to the wall of the large intestine and diarrhea present which is in conformation with our findings in this case. Adult parasites are found in the caecum and large intestine.…”

Presentation, Clinical Pathology Abnormalities, and Identification of Gastrointestinal Parasites in Camels (Camelus bactrianus and Camelus dromedarius) Presenting to Two North American Veterinary Teaching Hospitals. A Retrospective Study: 1980–2020

“…This animal expired and death was attributed to whipworm infestation (34). Two younger dromedaries 3-4 years of age at the Seoul Zoo developed anorexia and chronic diarrhea in association with whipworms (34). In this study, one case which was dead on arrival was identified as having whipworms with small intestinal and colonic enteritis.…”

Різноманіття Гельмінтофауни Ссавців В Умовах Зоопарків

“…Вивчення гельмінтологічної ситуації зоопарків є актуальним з огляду на можливість дослідження екзотичних тварин, що перебувають на обмеженій території, та отримання колекційних екземплярів гельмінтів, не притаманних фауністичному складу свійських тварин (Kharchenko and Marunchin, 1992;Eo et al, 2014;Kyung-Yeon et al, 2014;Gressler et al, 2016;Seguel and Gottdenker, 2017).…”
