The effectiveness of filter top cages in preventing infection of mice with pinworms, Aspiculuris tetraptera and Syphacia obvelata, was investigated by introducing mice from a pathogen-free colony into a colony in which both types of pinworms were enzootic. Half of the pathogen-free mice were maintained in filter top cages, while the remainder were held in similar cages without filters. All mice thus introduced were killed and examined after 3 to 8 week exposure periods. No pinworms were recovered from mice in 17 of 18 cages with filter tops while mice in 12 of 16 cages without filter tops were infected. [AS].
