Outer ear canal infection with Rhabditis sp. nematodes in a human.

A human case of outer ear canal infection with 3 Rhabditis sp . nematodes 4

Rhabditis pellio Schneider (nematoda) from the earthworm, Aporrectodea trapezoides Duges (Annelida).

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. Similar nematodes that entered the coelom were encapsulated and incorporated into multiple capsules ("brown bodies"). It was demonstrated that this hos...

Journal of Paediatric Care Insight Middle Ear Function in Human Immunodeficiency Virus (HIV)-Infected South African Children

Children with human immunodeficiency virus (HIV) infection are more likely to have hearing loss and are more susceptible to middle ear infections. The purpose of this study was to quantitatively measure middle ear function, using tympanometry, in perinatally HIV-infected (PHIV) and HIV-uninfected children living in Cape Town, South Africa.Hearing-related health questionnaire data were obtained ...

A 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...

Regulation of Sexual Plasticity in a Nematode that Produces Males, Females, and Hermaphrodites

The mechanisms by which new modes of reproduction evolve remain important unsolved puzzles in evolutionary biology. Nematode worms are ideal for studying the evolution of mating systems because the phylum includes both a large range of reproductive modes and large numbers of evolutionarily independent switches [1, 2]. Rhabditis sp. SB347, a nematode with sexual polymorphism, produces males, fem...
