Paragonimus

 [par″ah-gon´ĭ-mus]
a genus of trematode parasites, having two invertebrate hosts, the first a snail, the second a crab or crayfish. P. westerma´ni is the lung fluke, seen particularly in Asia, found in cysts in the lungs and sometimes the pleura, liver, abdominal cavity, and elsewhere in humans and other animals who have ingested contaminated fresh water crayfish or crabs.

Paragonimus

(par'ă-gon'i-mŭs),
A genus of lung flukes, parasitic in humans and a wide variety of mammals that feed on crustacea carrying the metacercariae.
[para- + G. gonimos, with generative power]

Paragonimus westermani

The lung fluke, a common parasite of certain mammals including humans, dogs, cats, pigs, and minks. Human infestation occurs through eating partially cooked crabs or crayfish, the second intermediate host. This infestation is endemic in certain parts of Asia. See: illustration

Paragonimus africanus, Paragonimus caliensis, Paragonimus iloktsuenensis, Paragonimus mexicanus, Paragonimus ohirai, Paragonimus peruvianus, Paragonimus uterobilateralis
found in the lungs of a large number of animal species.
Paragonimus kellicotti
found in the lungs of cat, dog and pig. Mink and muskrat are the probable primary hosts.

The nine studies cover catalytic activity in transcripts from Schistosoma non-autonomous retro-transposons, mobile genetic elements of malaria vectors and other mosquitoes, retro-transposons in the genomes of the digenean parasitic trematodes Clonochis sinensis and Paragonimus westermani, endogenous retro-transposon sequences of the Schistosoma mansoni intermediate snail host Biomphalaria glabrata, the transposon-mediated transgenis of mosquitoes, Schistosome long terminal repeat retro-transposons colonizing Schistosome genomes, Schistosome DNA transposons, and mobile genetic elements resident in hookworm genomes.
Africa also has a species of Paragonimus but the connection to human disease is not fully established.
Four lungworm species were found, including Capillaria aerophila, Oslerus osleri, Paragonimus kellicotti and Crenosoma vulpis.

Serologic testing showed high antibody titers against Dirofilaria antigen and moderate titers against Strongyloides antigen, but no significant antibody titers were found against other helminth antigens tested, including Toxocara, Cysticerca, Schistosoma, Fasciola, or Paragonimus species.
Samples of every new batch of ELISA kits used in the survey were randomly selected and tested with standard serum samples to determine their sensitivity and cross-reactivity with antibodies against hepatitis B virus and Paragonimus spp.
