Outer ear canal infection with Rhabditis sp. nematodes in a human.
Here we report the first human case of an outer ear canal infection with a free-living nematode of the genus Rhabditis. Otomicroscopy revealed viable worms in the outer ear canal of a patient suffering from chronic otorrhea and hearing loss. The nematode was identified by microscopy and internal transcribed spacer (ITS)-PCR.

Studies were conducted on the behavior of the nematode, Rhabditis pellio, in the earthworm, Aporrectodea trapezoides, from southern California. Juvenile and adult nematodes were found in the bladders and tubules of the metanephridia of the host.

متن کاملA further sibling species of Rhabditis (Pelodera) strongyloides (Nematoda) : Rhabditis (P.) cutanea n. sp. from the skin of wood mice (Apodemus sylvaticus)
Rhabditis cutanea n. sp., a new larval-parasitic species from the skin of Apodemus sylvaticus, is described. Cross-mating experiments revealed isolation from R. nidicolis Sudhaus & Schulte, 1986, R. orbitalis Sudhaus & Schulte, 1986, and R. strongyloides (Schneider, 1860). There are two modifications of third stage larvae named " dauerlarva " and infective larva ". It is hypothesized that the l...
