pentastomid การใช้

• There are about 130 extant species of pentastomids; all are obligate parasites with correspondingly degenerate anatomy.
• For the first time, fossils have been found of tardigrades ( " water bears " ) and apparently free-living pentastomids.
• The pentastomid reaches the main host when the intermediate host is eaten by the main host, and crawls into the respiratory tract from the oesophagus.
• The barn owl ( " Tyto alba " ) is among the most important; one study found that 97.5 % of vertebrate remains in barn owl lice, and fleas among external parasites and many nematodes and digeneans, a pentastomid, and several coccidians among internal parasites " ( see parasites of the marsh rice rat ) ".
