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.
This is because snails are hermaphrodites, meaning that they have the reproductive organs of both sexes on them, therefore they are able to produce both sperm and eggs. When they are mating they will both conceive and lay eggs. The average life span of a snail is approximately 10 to 15 years in captivity.
