Control II Surveillance in Swine and Other Animals by Muscle Examination

  • William J. Zimmermann

Abstract

The demonstration of Trichinella spiralis larvae (“trichinae”) in the musculature of man, swine, or other carnivorous animals is a positive determination of infection. Various methods of direct diagnosis have been used, including trichinoscopy (also known as the compression or microscopic method), digestion or mechanical disintegration of muscle tissue, biopsy and microscopic section of muscles, and xenodiagnosis. The desired method will vary with objectives and circumstances (such as whether examination is to be made on living or dead hosts), economics, especially when related to slaughterhouse examination of swine, degree of efficacy desired, amount of muscle sample available, stage of infection, and availability of equipment.
