title: Changes in the bacterial cecal flora of mice infected with Trichuris muris (Schrank, 1788).
abstract: Cecal microorganisms of mice were categorized and enumerated weekly during the developmental cycle of infection with the whipworm, Trichuris muris. The cecal bacterial population consisted of Escherichia coli, Proteus spp, Acinetobacter lwoffi (Mima polymorpha), aerobic lactobacilli, staphylococci, enterococci, and anaerobes (bacteroides, streptococci, and lactobacilli) in control and T. muris-infected mice. The aerobic lactobacilli and the anaerobes constituted the greatest number of organisms in both groups. In week three there was a decrease in the number of these organisms, and in week four fewer of these and of all other organisms in the worm-infected mice when compared to controls. The most significantly reduced bacterial counts were observed during the period of T. muris self-cure.
