(19) Arachnidism can be manifested either through the skin or systemically.
(20) Since guanine is not only an essential constituent of vital nucleic acids, but also the main end product of nitrogenous waste excretion in arachnids, it is a potential candidate for a hygienic index for mite activity in house dust.
Arthropod
Definition:
(n.) One of the Arthropoda.
Example Sentences:
(1) King crabs (Family Lithodidae) are among the world's largest arthropods, having a crab-like morphology and a strongly calcified exoskeleton.

(3) The method of detection of rickettsia in smears from the arthropods using the immunofluorescence technique and antibody response in mice inoculated with infected arthropods was found to be the most effective in these studies.
(4) The intensity of light for reliable cell killing (0.5 MW.m-2) was much greater than that used to kill arthropod neurones.
(5) The microsporidia are a group of unusual, obligately parasitic protists that infect a great variety of other eukaryotes, including vertebrates, arthropods, molluscs, annelids, nematodes, cnidaria and even various ciliates, myxosporidia and gregarines.
