Identify the correct statements about the classification of Leishmania species according to Lainson and Shaw (1972, 1973)

The parasitic agents causing American cutaneous leishmaniasis were grouped into two large complexes: mexicana and braziliensis.

The species of the mexicana complex only develop and colonize the parasite in the middle and anterior intestines of the vector insects.

The species of the braziliensis complex always show parasitic development in the posterior intestine of the host insect.

The inoculation of parasites in the nose skin of the hamster showed rapid development of a nodular lesion, histiocytoma type, in which the large presence of parasites contrasts with the almost total absence of the cellular response.
