Paramaecium (sometimes typeset as Paramæcium) was an Australian death/doom metal band formed in 1991. There is use of instrumentation like flutes, cellos and violins on some albums. Paramaecium is one of the few doom metal bands that focus on Christian lyrical themes and Christian concepts. According to Doom-metal.com, "what sets Paramaecium apart from other bands in the doom metal scene, is the fact that they are the only Christian death/doom band that made it to the top of the genre."
