MACRO AND MICROSCOPIC MORPHOLOGY OF LYSSA BODY IN DOG

Abstract

With the aim to study the gross and histomorphology of the lyssa body of dog, seven heads were collected from the healthy adult dogs used for dissection purpose in the laboratory of the Department of Anatomy and Histologyat Bangladesh Agricultural University, Mymensingh. The gross parameters such as weight, length and width were recorded for respective specimens.The present study revealed that the dog lyssa was pinkish white coloured and situated along the median plane on the ventral surface of the free portion of the tongue. The lyssa had more or less rod shaped. The weight, length and width of the lyssa were measured as 0.11 ± 0.01gm, 3.96 ± 0.4cm and 0.28 ± 0.03cm, respectively.Then the specimens were processed for histomorphology and stained with Hematoxylin and Eosin. The present study noticed that the entire body of the lyssa was formed from adipose tissue and striated muscle bundles, encircled by a thick connective tissue capsule of mainly collagen fibers.These results will be helpful to study the further functional importance of the lyssa body in dog.
