Arthropods are common vectors of disease. A vector is an organism which spreads disease-causing parasites or pathogens from one host to another. Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms.
The human botfly, Dermatobia hominis (Greek δέρμα, skin + βίος, life, and Latin hominis, of a human), is a species of botfly whose larvae parasitise humans (in addition to a wide range of other animals, including other primates [1]).
Arthropod eyes Head of a wasp with three ocelli (center), and compound eyes at the left and right. Most arthropods have sophisticated visual systems that include one or more usually both of compound eyes and pigment-cup ocelli ("little eyes"). In most cases, ocelli are only capable of detecting the direction from which light is coming, using ...
The arthropods are a phylum of animals with jointed legs; they include the insects, arachnids such as spiders, myriapods, and crustaceans. [1] Insects play many roles in culture including their direct use as food, [2] in medicine, [3] for dyestuffs, [4] and in science, where the common fruit fly Drosophila melanogaster serves as a model organism for work in genetics and developmental biology.
A recent morphological analysis recovered Pentastomida outside the arthropods, as sister group to a clade including nematodes, priapulids and similar ecdysozoan 'worm' groups. [23] Adding fossils, they suggested an extinct animal called Facivermis could be closely related to tongue worms. However it should be stressed that these authors did not ...
Arthropods are intermediate hosts of Hymenolepis nana, otherwise known as the "dwarf tapeworm," while humans are used as final hosts. Humans become infected and develop hymenolepiasis through eating infected arthropods, ingesting eggs in water inhabited by arthropods, or from dirty hands. This is a common and widespread intestinal worm.
Cyclops is intermediate host of dracunculiasis (guinea-worm disease) and fish tapeworm (Diphyllobothrium latum) infection. This disease can be passed to humans through drinking infected water. Dracunculiasis will rarely cause death but is a weakening disease. [4]
Arthropods are invertebrate animals having an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments
