donovani promastigotes were cultured to obtain metacyclic
forms in Schneider's insect media (pH--5.
Trypanothione reductase activity is prominent in metacyclic
promastigotes and axenic amastigotes of Leishmania amazonensis.
The midguts were also checked for metacyclic
promastigotes to confirm infection.
Fouladi and Orfi have shown that, if G is either a finite AC-group or a p-group of maximal class or a metacyclic
p-group, then G is an A(G)-group .
cruzi is transmitted to humans primarily through the infected feces of triatomine bugs that contain metacyclic
trypomastigotes (vectorial transmission).
cruzi forms convert into epimastigotes that proliferate and then differentiate into metacyclic
forms inside the posterior intestine of the triatomine.
The parasites replicate as promastigotes and develop into infective metacyclic
promastigotes in the sandfly vector, and the infective promastigotes invade the macrophages and differentiate into amastigotes in the mammalian host (2).
Large-scale rearing of Rhodnius prolixus and preparation of metacyclic
trypomastigotes of Trypanosoma cruzi.
After 7-9 days, the infectious metacyclic
stages are found in the proboscis, ready to be injected into a new host during feeding.
Mexican Trypanosoma cruzi isolates: in vitro susceptibility of epimastigotes to anti-Trypanosoma cruzi drugs and metacyclic
forms to complement-mediated lysis.
Among the problems they solve here are classifying p-groups all of whose non-normal subgroups have normalizers of index p, and computing the number of subgroups of given order in metacyclic
Quantitative studies are difficult to compare because the population density of the parasites is influenced by several factors and because small amounts of metacyclic
forms are eliminated in the feces of the vector (Piesman and Sherlock, 1985; Contreras et al.
