Goldfaden's troupe began as all-male; while they soon acquired actresses, as well, it remained relatively common in Yiddish theatre for female roles, especially comic roles, to be played by men. (Women also sometimes played men's roles: Molly Picon was a famous Shmendrick .) Many early Yiddish theatre pieces were constructed around a very standard set of roles: "a prima donna , a soubrette , a comic, a lover, a villain , a villainess (or "intriguer"), an older man and woman for character roles, and one or two more for spares as the plot might require," and a musical component that might range from a single fiddler to an orchestra.  This was very convenient for a repertory company, especially a traveling one. Both at the start and well into the great years of Yiddish theatre, the troupes were often in one or another degree family affairs, with a husband, wife, and often their offspring playing in the same troupe.
The Ebola virus can be diagnosed with the particular antigens discovered in blood samples, isolation of virus in cell cultures, or identification of IgM and IgG antibodies. ELISA (Enzyme-linked immunosorbent assay) tests are frequently utilized in order to identify viruses. It should be mentioned that all tests are performed in the most rigorous laboratory conditions aiming to secure scientists and patients. There is considered to be no identified treatment for Ebola virus disease. Therefore, contaminated patients are treated by means of utilizing antiviral drugs, including ribavirin. Another method is a generally supportive therapy which restores endovenous fluids, keeps blood pressure in a good condition, and controls other bodily functions (Lovgren, 2003).
