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 life expectancy of snails in the wild is about 3 to 7 years, but in captivity, they can live up to 10-15 years or even more. Snail shell is made of calcium carbonate and keeps growing as long as the snail grows. They keep adding more calcium carbonate to the edge until the snail reaches adult size.
