Lysozyme is present in the salivary secretions and a low level has been reported for the bile and the pancreatic juice. It has been found to be absent from the digestive material of the rabbit stomach and small and large intestines as well as from the intestinal secretions taken from temporary fistulae placed at the duodenal, jejunal, ileal and colic levels. However, secretions obtained by permanent intestinal and gastric fistulae showed high enzyme levels. Lysozyme is thus of probable plasmatic origin. The question of Paneth cell secretion is still to be determined.
溶菌酶存在于唾液分泌物中，据报道胆汁和胰液中也有少量溶菌酶。研究发现，兔胃、小肠和大肠的消化物质以及取自十二指肠、空肠、回肠和结肠水平的临时瘘管的肠分泌物中均不存在溶菌酶。然而，通过永久性肠瘘和胃瘘获得的分泌物显示出较高的酶水平。因此，溶菌酶可能来源于血浆。潘氏细胞分泌的问题仍有待确定。
