Lancefield groups C and G comprise a variety of species; one of those species, Streptococcus dysgalactiae subsp. equisimilis (SDSE), frequently causes human infections. This species can cause the whole spectrum of infections caused by S. pyogenes (4,5).
Snails belong to the class Gastropoda, a classification that includes land, freshwater and sea snails and slugs. Snailsâ ancestors are one of the earliest known types of animals in the world.
The lifespan of land snails varies from species to species. In the wild, Achatinidae snails live around 5 to 7 years and Helix snails live about 2 to 3 years. Many deaths are due to predators or parasites.In captivity, the lifespan of snails is much longer than in the wild, ranging from 10 to 15 years for many species.On occasion, snails have lived beyond this lifespan, up to 25 years.gg sizes differ between species, from a 3 mm diameter in the grove snail to a 6 mm diameter in the Giant African Land Snail. After 2 to 4 weeks of favorable weather, these eggs hatch and the young emerge. Snails may lay eggs as often as once a month.
