Abstrakt: The percentage of parasitisation and index of adherence of Trypanosoma cruzi has been studied when host HeLa cells or metacyclic forms were pretreated with neuraminidase or with poly- l-lysine. The percentage of parasitisation was significatively reduced ( P≦0.001) when cells were pretreated with poly- l-lysine while pretreatment with neuraminidase caused no apparent effects. On the other hand, the adherence of the metacyclic forms pretreated with poly- l-lysine or neuraminidase was significantly higher than that of the control group. [ABSTRACT FROM AUTHOR]
