RESUMO
A female, 5 yr old Bactrian camel was presented to the Exotic and Wildlife Medicine Unit, School of Veterinary Medicine, Aristotle University of Thessaloniki, Thessaloniki, Greece, with severe dehydration, depression, anorexia, mild dyspnea and diarrhea. Supportive treatment immediately initiated with fluids, electrolytes and broad-spectrum antibiotics. The general condition of the animal was stable for the next 3 days, but at 4th day became worse, since the camel remained in sternal recumbency, denied to drink water and abortion of a mummified fetus was noticed. The aborted fetus and fetal membranes were submitted for laboratory examinations (bacterial cultures, MZN, cytology, PCR) that revealed Toxoplasma gondii infection. Treatment with sulfadimidine improved the situation of the animal that returned to its farm 1 week later. This seems to be the first reported case in the literature of confirmed toxoplasmic abortion in camels.
RESUMO
The Mediterranean monk seal (Monachus monachus) is classified by the IUCN as "endangered," with a global population estimated to number fewer than 800 individuals. Our understanding of the biology and health status of the species is still limited, rendering every medical case a challenge for conservationists and veterinary clinicians. Although studying and managing disease in wild marine hosts is complex and challenging, studying and mitigating the effects of any disease to the Mediterranean monk seal is of utmost importance for conservation. The aim of this study was to document for the first time the presence of the hookworm Uncinaria hamiltoni in rehabilitated Mediterranean monk seal pups in Greece. A detailed examination protocol was followed for all pups that live-stranded over 30 years in 22 different locations, including physical, parasitological, and other examinations. Hookworms (adults and/or eggs) were detected in all the fecal samples, from all animals. Molecular identification using MtDNA (COI) and ribosomal DNA (D2/D3 28S and internal transcribed spacer [ITS] regions) identified the nematode species as Uncinaria hamiltoni. The clinical impacts and the benefits of anthelmintic treatment as a tool for the conservation management of the species are discussed.
RESUMO
OBJECTIVE: Canine ocular onchocercosis may represent an important ocular disease with zoonotic potential and widespread geographical distribution. An uncommon localization of Onchocerca lupi adult worm in the anterior chamber of the eye is described for the first time. ANIMAL STUDIED: A 4-year-old, intact, male, mixed-breed dog was admitted with profuse lacrimation and severe squinting. On the right eye, there were mucopurulent discharge, chemosis, and all typical signs of anterior uveitis which were attributed to the presence of a moving filarial worm within the anterior chamber. PROCEDURE: Removal of the parasite from the anterior chamber by a limbal incision revealed a mature adult male, 7.65-cm-long O. lupi worm. Periocular skin scrapings for the corresponding microfilariae were negative. Postoperatively, apart from systemic prednisolone and doxycycline hyclate and a topical antibiotic/steroid solution, parenteral melarsomine, followed by ivermectin, was given until the complete disappearance of the ocular lesions. CONCLUSIONS: Intraocular onchocercosis should be included in the differential diagnosis of canine anterior uveitis in endemic areas. This case highlights the atypical localization of O. lupi in the canine eye emphasizing on the possibility for a complete cure after the surgical removal of the parasite and the filaricidal medication subsequently applied.
RESUMO
Globalization has increased circulation of people, their food, livestock and pets in the world, and changes in the environment, climate and human behaviour have led to the rapid expansion of emerging infections throughout the world. One of the reasons of a new pathogen affecting humans is the passage from an animal to a human being. Onchocerca (O.) lupi, a filarial worm first described in a wolf in 1967, is an emerging pathogen which has been incriminated as the etiological agent for 205 canine, 2 feline and 18 human infections in Europe, Tunisia, Turkey, Iran and the USA. Most frequent findings in animals and humans are monolateral or asymmetrical variably painful subconjunctival swellings and nodules containing immature or mature worms affecting the eye and/or adjacent tissues accompanied by conjunctival hyperemia. Occasionally, subcutaneous nodules and masses affecting the spinal cord have been observed in humans. Diagnosis of O. lupi is achieved by microscopy of excised adult female worms which exhibit a particular cuticular structure and molecular analysis. Treatment consists in worm removal accompanied by antihelminthic, antibiotic and anti-inflammatory therapy.
