    • A method to obtain rapid zoosporogenesis of Pythium insidiosum 

      Mendoza, Leonel; Prendas, Jorge (Kluwer Academic Publishers, 1988-10)
      Nine strains of Pythium insidiosum the etiologic agent of pythiosis, were inoculated on 2% water agar plus grass blades and then incubated one day at 25°C, 35°C and 37°C. Sporangium and secondary biflagellate-type zoosporas ...

    • Antigenic relationship between the animal and human pathogen Pythium insidiosum and nonpathogenic Pythium species 

      Mendoza, Leonel; Kaufman, Leo; Standard, Paul (American Society for Microbiology, 1987)
      Identification of the newly named pathogenic oomycete Pythium insidiosum and its differentiation from other Pythium species by morphologic criteria alone can be difficult and time-consuming. Antigenic anaysis by ...

    • Chagas' disease: Risk factors for house infestation by Triatoma dimidiata, the major vector of Trypanosoma cruzi in Costa Rica 

      Starr, Mark D; Rojas, Julio C; Zeledon, Rodrigo; Hird, David W; Carpenter, Tim E (The Johns Hopkins University School of Hygiene and Public Health., 1991)
      The reduction of domiciliary infestation by insect vectors, the key to controlling Chagas' disease, depends on identification of housing features associated with infestation. In this study, log-linear modeling was used to ...
