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 average life span of a snail is approximately 10 to 15 years in captivity. However, it is believed that some species can live up to 25 years this way. In the wild however, lifespan varies from species to species, but range from 2-3 in some cases to 5-7 for other kinds of land snails.nailsâ ancestors are one of the earliest known types of animals in the world. There is fossil evidence of primitive gastropods dating back to the late Cambrian period; this means that they lived nearly 500 million years ago.
