|
|
|
pentasomes
|
are pleomorphic, resembling mites during their larval stage and demonstrating annelid (worm-like) characteristics during their nympal and adult stages.
|
|
|
what does penta mean
|
five and stome meaing mouth, five mouths was chosen becuse these parasietes as adults have a mouth on the anterial that is surrounded by four hooked claws
|
|
|
what are some other names for pentasome?
|
tongue worm and linguatulids beause of their distinct tongue-shaped appearance
|
|
|
what is the life cycle of a reptilian pentasome like?
|
occur mostly in the lungs, trachea, and nasal passages of the reptiilian definitive host feeding on tissue fluids and blood cells. female pentasomes produce several million fully embryonated eggs, each containing a single larvae with 2-3 pairs of rudimentary claws
|
|
|
what is interesting about the larvae of pentasomes?
|
they have 4-6 stumpy legs, each of which has one or two retractable pincer like claws, hatch from the eggs and are infective for the intermediate host (rodents, herbivores, carnivore)
|
|
|
what do pentasome larvae do when they are in the gut?
|
they bore through the intestinal wall of the intermediate host and pass with the blood to the mesenteric lymph nodes, the liver, lungs, omentum, or another internal organ where is becomes encysted. The larvae becoe quiescent and change into the annelid worm-like nymphal stage which can pass through as many as 5 molts
|
|
|
how does the reptile definitve host become infected?
|
by ingesting the intermediate host with its encysted nymphal pentasomes. The infected nymps penetrat the host's intesting and bore into the lungs, where they become sexually mature adult parasites
|
|
|
what are the signs of an infected animal w/ pentasomes
|
lethargy, anoerxia, dyspnea, and production of blood-tinged sputum or mucus with the pharynx or the trachea. The sputum and the feces can contain eggs that microscopically appear and contain 4-6 legged larvae with retractable claws. CBC reveals leukocytosis and eosinophilia. Rads might reveal adult worns or remnants of calcified cysts
|
|
|
what do the pentasomes do when the reptile is stressed?
|
they attempt to leave the host through the mouth, nostrils, or body wall
|
|
|
Linguataula serrata
|
the canine pentasome found in the nasal and paranasal sinuses of dogs, wild canids,and cats
|
|
|
what are the intermediate hosts for linguataula serrata?
|
rats, procupiines, g.pigs, rabbies, hedgehogs, pigs, and wild and domestic ruminants. rabbits most common in north america
|
|
|
what happens with fully developed linguataula?
|
they ar the infective stage for carnivores. Nymphs may be found ina variety of organs, spleen, liver, and mesenteric lymph nodes. Humans become incidental hosts by eating raw or undercooked meat or meat by products that contain nymphal stages. soonoic
