Association of Microorganisms with the Epithelium in the Alimentary Tract of Aspicularis tetraptera

ABSTRACT

Parasitic nematode worms (Aspicularis tetraptera) were observed microscopically in histological sections of the colons of C57BL/6StCrl female mice. These nematodes have gram-positive bacteria intimately associated with the mucosal epithelium in their alimentary tract.
