[Biology of the taeniasis-cysticercosis binomial].

We present a review of the biological aspects of taeniasis-cysticercosis binomial, emphasizing those related to its biotic potential, resistance, and viability of eggs in the environment, as well as the morphological features of the corresponding adults, which are instrumental for the diagnosis of taeniasis. A new infection mechanism through the ingestion of posoncospheres present in macerated meat is discussed. The significance of unifying epidemiological criteria to control this important binomial is pointed out.
