Sk. Theisen et al., PHYSALOPTERA INFECTION IN 18 DOGS WITH INTERMITTENT VOMITING, The Journal of the American Animal Hospital Association, 34(1), 1998, pp. 74-78
Physaloptera infections were diagnosed endoscopically in 18 dogs. Each
case had vomiting as the primary clinical sign, and four cases had re
gurgitation as a concurrent sign. Fecal flotations, using magnesium su
lfate solution, were performed in 12 of the 18 cases and were negative
for Physaloptera eggs. In 12 of the 18 cases, only one worm was seen
during endoscopic examination. Fifteen of 18 cases were treated with p
yrantel pamoate, and 10 of 12 cases with follow-up had resolution of t
heir vomiting.
