      Fresh-frozen lung and tracheal-aspirate specimens obtained from 112 infants who died in Santiago, Chile, during 1998-2000 were analyzed for the presence of Pneumocystis DNA, by use of nested DNA amplification of the large ...
    • Ambrose, Helen E.; Ponce, Carolina A.; Wakefield, Ann E.; Miller, Robert F.; Vargas Munita, Sergio (Oxford University Press, 2001)
      Pneumocystis f. sp. hominis causes pneumonia in immunocompromised persons. In order to determine the types and distribution of P. carinii organisms within a single human lung, multiple samples were obtained from the lung ...
    • Rojas, Pilar; Friaza, Vicente; García, Elisa; Horra, Carmen de la; Vargas Munita, Sergio; Calderon, Enrique J.; Pavon, Antonio (Oxford University Press, 2017)
      Background. Pneumocystis pneumonia is a well-recognized lung disease of premature and malnourished babies. Even though serologic studies have shown that children are exposed to Pneumocystis jirovecii early in life, the ...
