title: [A comparative study of the Feira de Santana (Bahia) and Porto Rico strains of Schistosoma mansoni in experimental infection of mice].
abstract: A comparative study of mice infected either with the Porto Rican or a Brazilian (Feira de Santana) strain of Schistosoma mansoni failed to show any difference regarding recovery of five day lung worms, recovery of adult worms from the portal system, number of eggs per gram of tissue in liver and intestines, histopathology or mortality rate. In fact, the differences, although small, were greater among animals infected with the same strain, that when the total results from both strains were compared.
