Topical medications (medications you put on your skin), like those used to remove warts, can also help remove the papules. Molluscum Contagiosum Prevention The molluscan shell appears to have originated from a mucus coating, which eventually stiffened into a cuticle. This would have been impermeable and thus forced the development of more sophisticated respiratory apparatus in the form of gills. [45] Eventually, the cuticle would have become mineralized, [45] using the same genetic machinery ( engrailed) as most other bilaterian skeletons. [79] The first mollusc shell almost certainly was reinforced with the mineral aragonite. [28] Molusky sú malé, ale neuveriteľne vytrvalé, otravné a vzhľadom k vírusovému pôvodu tiež veľmi nákazlivé hrbolčeky vo veľkosti špendlíkovej hlavičky. Zvyčajne sa však na tele nevyskytuje jeden hrbolček, ale sú vo väčšom počte. Síce molusky trápia predovšetkým batoľatá a predškolákov, niekedy sa nevyhnú ani dospelému. Molluscum contagiosum papules commonly appear on the face, trunk, and limbs of children and on the genitals, abdomen, and inner thighs of adults. The condition usually causes bumps that: The three most universal features defining modern molluscs are a mantle with a significant cavity used for breathing and excretion, the presence of a radula (except for bivalves), and the structure of the nervous system. Other than these common elements, molluscs express great morphological diversity, so many textbooks base their descriptions on a "hypothetical ancestral mollusc" (see image below). This has a single, " limpet-like" shell on top, which is made of proteins and chitin reinforced with calcium carbonate, and is secreted by a mantle covering the whole upper surface. The underside of the animal consists of a single muscular "foot". Although molluscs are coelomates, the coelom tends to be small.

The major classes of mollusks vary in structure and function. You can read about some of their differences in Figure below. Molluscs are generally regarded members of the Lophotrochozoa, [74] a group defined by having trochophore larvae and, in the case of living Lophophorata, a feeding structure called a lophophore. The other members of the Lophotrochozoa are the annelid worms and seven marine phyla. [77] The diagram on the right summarizes a phylogeny presented in 2007 without the annelid worms. Zong-Jie, F.

Pojavnost ter njeno število je zelo spremenljivo in zavisi od osebe do osebe - pojavljajo se pogosto v skupinah in sicer lahko celo po več kot 100 moluskov v skupini. To obolenje še posebej prizadene majhne otroke; povzročijo jih ponavadi šolske epidemije. Pojavnost moluskov je manj pogosta pri odraslih. Nastanejo na katerem koli delu telesa in so običajno združene v določenem območju, vendar so moluski lahko tudi razpršeni. Okužba z moluski je zelo nalezljiva (otrok se inficira predvsem na bazenih, ter ob uporabi skupnih predmetov - gobice, brisače ali neposredno ob stikih kože z vrstniki).

Mollusks are an important phylum of invertebrate animals. Most of them are marine animals, which means they live in the ocean. They have huge numbers in-shore, that is, in shallow water. They are the largest marine phylum, with about 85,000 living species, 23% of all named marine organisms. They also occur in freshwater and on land.

Estimates of accepted described living species of molluscs vary from 50,000 to a maximum of 120,000 species. [1] The total number of described species is difficult to estimate because of unresolved synonymy. In 1969, David Nicol estimated the probable total number of living mollusc species at 107,000 of which were about 12,000 fresh-water gastropods and 35,000 terrestrial. The Bivalvia would comprise about 14% of the total and the other five classes less than 2% of the living molluscs. [18] In 2009, Chapman estimated the number of described living mollusc species at 85,000. [1] Haszprunar in 2001 estimated about 93,000named species, [19] which include 23% of all named marine organisms. [20] Molluscs are second only to arthropods in numbers of living animal species [17] — far behind the arthropods' 1,113,000 but well ahead of chordates' 52,000. [15] :Front endpaper About 200,000living species in total are estimated, [1] [21] and 70,000 fossil species, [14] although the total number of mollusc species ever to have existed, whether or not preserved, must be many times greater than the number alive today. [22] Molluscum contagiosum tends to be more numerous and last longer in children who also have atopic dermatitis, due to deficiencies in the skin barrier. It can be very extensive and troublesome in patients with human immunodeficiency virus ( HIV) infection or that have other reasons for poor immune function. What causes molluscum contagiosum? One of the most important mollusc collections at the Museum is of marine shells collected from Port Alfred by Turton, W.H. (1856 - 1938). The shells are listed and figured in Turton’s publication The marine shells of Port Alfred, S.Africa, and the collection contains several hundred type specimens. There are other type specimens in the fluid-preserved and dry collections. Wägele, H. (March 1989). "Diet of some Antarctic nudibranchs (Gastropoda, Opisthobranchia, Nudibranchia)".
