In this article we study the problem of finding such finite groups that the modular forms associated with all elements of these groups by means of a certain faithful representation belong to a special class of modular forms (so-called multiplicative η−products). This problem is open. We find metacyclic groups with such property and describe the Sylow p-subgroups, p 6= 2, for such groups. We als...

stage-specifci developmental forms of lesihmania major promastigotes were grown in vitro. procyclic and metacyclic promastigotes were cultured and separated by peanut agglutinin. the axenic amastigote form were prepared by culturing the promastigotes in acidic medium at 35c.these three forms of parasites were used as antigens to study cytokine production in whole blood culture of healthy indivi...

Serial passage of axenically-cultured Leishmania chagasi promastigotes results in a progressive diminution in resistance to complement mediated lysis (CML), whereas high CML resistance is seen in infectious metacyclic promastigotes from the sandfly vector as well as metacyclic-like promastigotes within low passage cultures at stationary growth phase. As previously reported [94], in a screen see...

A modified infection and maintenance procedure for the cyclical transmission of T. (T.) brucei in Glossina m. morsitans is described which produced high mature infection rates in the flies. Freshly extruded metacyclic forms and bloodstream forms were serologically typed, using the indirect fluorescent antibody test (IFAT) and the neutralization infectivity test (NIT). Metacyclic forms of a cert...
