Table 1. Prevalence (%), mean intensity of infection (MII) ± standard deviation, mean abundance (MA), range (RA) and sites of infection (SI) of helminths associated with freshwater turtles Phrynops geoffroanus and Mesoclemmys tuberculata from Caatinga and Atlantic Forest areas, Northeast Brazil. Sites of infection: St = stomach; Es = oesophagus; I = intestine; L = lungs and CC = coelomic cavity. *Values referring to the intensity of total infection.
