In the case of gnathostomiasis, the patient may show edema, eosinophilia and leukocytosis. In mature dogs with some acquired immunity, infective larvae may not develop directly into adults, but rather migrate to somatic tissues such as kidney and skeletal muscle, where they undergo prolonged arrested development [7]. The genus Uncinaria provides an excellent example of how ancylostomatoid nematode life cycles can be adapted to differing environmental conditions. The larvae produce serpiginous tunnels under the skin and do not undergo further development. Uncinaria lucasi (seals and sea lion pups in Pacific) Uncinaria stenocephala (carnivores, mainly canids, in Northern hemisphere) Superfamily: Strongyloidea (strongilids) Species have large, complex buccal capsules Some with corona radiata, which is a series of leaf-like structures surrounding mouth Light infections are asymptomatic.
