Detection of Cytokines and Collectins in Bronchoalveolar Fluid Samples of Patients Infected with and .

Histoplasmosis and pneumocystosis co-infections have been reported mainly in immunocompromised humans and in wild animals. The immunological response to each fungal infection has been described primarily using animal models; however, the host response to concomitant infection is unknown. The present work aimed to evaluate the pulmonary immunological response of patients with pneumonia caused either by , , or their co-infection.

Detección y genotipificación de Pneumocystis jirovecii en muestras de pacientes mexicanos VIH positivos y negativos.

Introduction: Pneumocystis jirovecii is an atypical fungus particularly detected in HIV-positive or transplant patients.

Objective: To detect and genotype Pneumocystis jirovecii in patient samples from two hospitals in Mexico City.

Method: Eighty-nine respiratory tract samples, corresponding to 53 patients (30 HIV-positive and 23 HIV-negative) with respiratory symptoms and to 11 healthy individuals included as negative control, were processed.

Histoplasma capsulatum and Pneumocystis jirovecii coinfection in hospitalized HIV and non-HIV patients from a tertiary care hospital in Mexico.

Background: Histoplasma capsulatum and Pneumocystis jirovecii are respiratory fungal pathogens that principally cause pulmonary disease. Coinfection with both pathogens is scarcely reported. This study detected this coinfection using specific molecular methods for each fungus in the bronchoalveolar lavage (BAL) of patients from a tertiary care hospital.
