pentastomiasis in bosc s monitor lizards varanus exanthematicus caused by an undescribed sambonia species
Journal of Zoo and Wildlife Medicine, 2009Co-Authors: E J Flach, John Riley, Adrian Mutlow, Irene A P MccandlishAbstract:Abstract Two wild-caught Bosc's monitor lizards (Varanus exanthematicus) developed clinical signs of pentasomiasis approximately 3 yr after arrival in the United Kingdom. One died of chronic Parasitic Pneumonia associated with adult pentastomids of an undescribed Sambonia species. Eggs and immature pentastomids were also seen in histologic sections of the lungs and liver. The other animal was treated for Pneumonia and for nodular inflammation of the larynx that restricted the diameter of the glottis. Fragments of pentastomid larvae were seen in a laryngeal biopsy, and the animal recovered after treatment with ivermectin and supportive therapy.

Parasitic Pneumonia in roe deer (Capreolus capreolus) in Cornwall, Great Britain, caused by Varestrongylus capreoli (Protostrongylidae)
BMC Veterinary Research, 2018Co-Authors: Victor R. Simpson, Damer P. BlakeAbstract:Background Roe deer ( Capreolus capreolus ) became extinct over large areas of Britain during the post mediaeval period but following re-introductions from Europe during the 1800s and early 1900s the population started to recover and in recent decades there has been a spectacular increase. Many roe deer are shot in Britain each year but despite this there is little published information on the diseases and causes of mortality of roe deer in Great Britain. Case presentation The lungs of two hunter-shot roe deer in Cornwall showed multiple, raised, nodular lesions associated with numerous protostrongylid-type nematode eggs and first stage larvae. There was a pronounced inflammatory cell response (mostly macrophages, eosinophils and multinucleate giant cells) and smooth muscle hypertrophy of the smaller bronchioles. The morphology of the larvae was consistent with that of a Varestrongylus species and sequencing of an internal transcribed spacer-2 fragment confirmed 100% identity with a published Norwegian Varestrongylus cf. capreoli sequence. To the best of the authors’ knowledge this is the first confirmed record of V. capreoli in Great Britain. Co-infection with an adult protostrongylid, identified by DNA sequencing as Varestrongylus sagittatus , was also demonstrated in one case. Conclusions Parasitic Pneumonia is regarded as a common cause of mortality in roe deer and is typically attributed to infection with Dictyocaulus sp. This study has shown that Varestrongylus capreoli also has the capability to cause significant lung pathology in roe deer and heavy infection could be of clinical significance.

ATYPICAL DICTYOCAULUS VIVIPAROUS-ASSOCIATED BOVINE ACUTE PNEUMONITIS: REMINISCENT OF LARVAL HYPOBIOSIS DURING THE WINTER?
2017Co-Authors: Bayrou Calixte, Dernier Adrienne, Cassart Dominique, Losson Bertrand, Desmecht DanielAbstract:Dictyocaulus viviparus is the aetiological agent of verminous bronchitis in cattle. Herein we describe an atypical case of Parasitic pneumonitis in an adult cow. Methods At the end of March 2017, a 3-yr old Belgian Blue cow suddenly displayed a marked respiratory distress syndrome a few hours after C-section calving. In spite of the treatment set up by the local veterinarian, the cow died 48 hours later. The body was referred to the Veterinary Faculty of Liège (Belgium) for necropsy. Post- mortem gross examination revealed a severe, acute interstitial pneumonitis with concurrent emphysema and a significant amount of parasites (Dictyocaulus viviparus) in the bronchi. The microscopic examination confirmed the severe acute interstitial pneumonitis with foci of hemorrhages, necrosis, hyaline membranes and hyperplasia of type II pneumocytes. Larvae were also present in the alveoli and bronchioles. Results Altogether, theses clinical observations and lesions were compatible with a hypersensitivity reaction against worm antigens. Additionally, Baermann’s test was performed on feces collected from the cadaver and from 5 others cows kept under the same conditions. Four out of 6 cows were excreting small amounts of Dictyocaulus stage-1 larvae. Conclusions Parasitic Pneumonia is a very common disease in first year grazing young cattle. In this case, cow’s age and disease manifestation time were very uncommon. Three-year-old cows are supposed to be fully protected against this nematode species. Moreover, in Belgium, at the end of March, livestock is still kept indoors (zero grazing winter period). Therefore, this case could highlight the hypobiotic capacity of Dictyocaulus viviparus larvae and associated « periparturient rise » phenomenon, both well known in sheep, but not described in cattle so far. We herein discuss the farming conditions that promoted such a severe Parasitic respiratory disease
