Abstract

Fifty apparently healthy island dogs presenting to the Ross University School of Veterinary Medicine (RUSVM), St. Kitts, West Indies for neutering were used in this prospective study. Twelve of the dogs (24%) were diagnosed with spirocercosis based on a positive fecal analysis and characteristic lesions seen during esophagoscopy. Routine thoracic survey radiographs revealed changes previously reported with spirocercosis in 10/12 (sensitivity
= 83%) infected dogs, but in none of the uninfected dogs (38/38; specificity = 100%). The most common radiographic changes were an increased fluid density within the caudal
dorsal thorax on the lateral view and a widening and/or bulging of the caudal mediastinum on the dorsoventral view. After oral administration of barium sulfate, barium retention or a tortuous esophagus was visible in all infected dogs (12/12; sensitivity 100%) and in one
uninfected dog (1/38; specificity 97%). The results show spirocercosis is common on St. Kitts and that radiographs are as dependable as fecal analysis and/or endoscopy in
diagnosing the condition.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
