Identification and characterization of microsatellite markers in the Chagas disease vector Triatoma infestans (Heteroptera: Reduviidae).

Triatoma infestans, the main vector of Chagas disease in the southern cone countries, is the principal target of a regional elimination program. A better understanding of its dispersal, sources of reinfestation, and insecticide resistance is key to an effective control program. To address such problems, we identified and characterized 13 microsatellite loci of T.

Severity and outcome of HIV-associated Pneumocystis pneumonia containing Pneumocystis jirovecii dihydropteroate synthase gene mutations.

Background: The impact of Pneumocystis jirovecii (formerly P. carinii) dihydropteroate synthase (DHPS) gene mutations on morbidity and mortality of Pneumocystis pneumonia (PCP) in HIV-positive patients is unclear.

Objective: To determine whether severity and outcome of HIV-associated PCP differs according to DHPS genotype.

Prevalence and clinical predictors of Pneumocystis colonization among HIV-infected men.

Background: The epidemiology and transmission of Pneumocystis are poorly understood. The incidence of colonization, or detection of organisms without signs of disease, has been debated, and risk factors for colonization are largely unknown.

Objective: To determine the rate of Pneumocystis colonization among HIV-infected patients at autopsy and analyze associated clinical variables.
