Pinworms (Nematoda: Oxyurida) are common contaminants in most laboratory rodent colonies. The aim of the study was to monitor the transmission of Syphacia muris eggs in laboratory rat breeding facilities. Dust in a breeding room was investigated using special grids (free fallout, or through the help suction chamber). Furthermore, the ventilation system, breeding cages and the hands of the laboratory technical staff were examined. In the case of free fallout, the percentage of positive grids increased slightly over time: from 5.5% (after 24 h) to 8.2% (72 h). Similar values were also found when using the suction chamber (7.6%). Many more pinworm eggs were found in samples collected every second month from suction holes of the ventilation system (28.7%). One-half of the samples taken from the breeding cages (before washing) exhibited pinworm eggs (50.8%). Examination of the hands of technical staff showed positive detection in 37.9% of cases. In this study, certain transmission factors (dust, unclean cages and technicians) were proved to be significant in the distribution of pinworm infection in laboratory rodent facilities.

The study presents the first description of male specimen (allotype) of the pinworm species Lemuricola (Lemuricola) pongoi, parasitising Sumatran orangutan (Pongo abelii) from Sumatra (Indonesia). The male specimen morphology presents all features fully corresponding with diagnose of the genus and subgenus Lemuricola. We are agreeing that Protenterobius is synonymous with Lemuricola because the length of tail appendix in males is not a sufficient feature for separation of the genera or subgenera. For L. (L.) pongoi male are characteristic features: body length (4,803 microm), total oesophagus length (530), tail length (235), tip of tail length (188) and spicule length (90).
