Sparganosis is a parasitic infection caused by the plerocercoid larvae of the genus Spirometra including S. mansoni, S. ranarum, S. mansonoides and S. erinacei. [1] [2] It was first described by Patrick Manson in 1882, [3] and the first human case was reported by Charles Wardell Stiles from Florida in 1908. [4]
There are three ways in which humans have become infected in the past: 1) Eating raw or under cooked snakes, frogs, and other four footed animals; 2) drinking contaminated water containing infected copepods; and 3) using raw snake or frog flesh in poultices that come in contact with intact human skin (Spirometra larvae have been shown to ...
Titicaca water frogs tend to be most active during the night. [24] The Titicaca water frog breeds year-round in shallow coastal water where the female lays about 80 to 500 eggs. [4] [21] Amplexus lasts one to three days. [16] The "nest" site is typically guarded by the male until the eggs hatch into tadpoles, [21] which happens after about one ...
The eggs of amphibians are typically laid in water and hatch into free-living larvae that complete their development in water and later transform into either aquatic or terrestrial adults. In many species of frog and in most lungless salamanders (Plethodontidae), direct development takes place, the larvae growing within the eggs and emerging as ...
Adult frogs live in fresh water and on dry land; some species are adapted for living underground or in trees. Frogs typically lay their eggs in the water. The eggs hatch into aquatic larvae called tadpoles that have tails and internal gills. They have highly specialised rasping mouth parts suitable for herbivorous, omnivorous or planktivorous ...
Frogs in amplexus are frequently observed on top of floating vegetation (e.g. duckweed) in shallow (< 50 cm) water. Eggs are laid singly, usually attached in small groups or rows along stems of submerged vegetation or leaves, or on the substrate in shallow water. [3]

Maggot therapy (also known as larval therapy) is a type of biotherapy involving the introduction of live, disinfected maggots (fly larvae) into non-healing skin and soft-tissue wounds of a human or other animal for the purpose of cleaning out the necrotic (dead) tissue within a wound (debridement), and disinfection.
