We have examined by gelatin-SDS-PAGE the protease activity in cell lysates of Giardia duodenalis trophozoites of two axenic strains isolated in Brazil from a symptomatic patient (BTU-11) and an asymptomatic carrier (BTU-10), and the reference strain Portland 1 (P1). The proteolysis band patterns showed differences among strains isolated from asymptomatic and symptomatic individuals. The lysate ...

A total of 1602 routine rectal swab specimens and 341 diarrhoeal specimens were obtained over a period of one and a quarter years from a group of children of semi-urban areas in the town of Vellore, North Arcot District, Tamil Nadu, India. Shigellae were found in 16.1 % of the specimens obtained at the time of diarrhoeal episodes. A 4.9 % incidence of asymptomatic infection with Shigella specie...

Abstract Background Resting‐state connectivity allows for investigating brain network changes in pathologic states of aging, such as Alzheimer’s Disease (AD). Recently, have been associated with AD‐related risk factors asymptomatic individuals. We explored how is affected by one factor, apolipoprotein e4 ( APOE4) carrier status. Methods In a sample cognitively healthy older adults (n=102), we a...

Facioscapulohumeral muscular dystrophy (FSHD) is a progressive muscle disorder that has been associated with a contraction of 3.3-kb repeats on chromosome 4q35. FSHD is characterized by a wide clinical inter- and intrafamilial variability, ranging from wheelchair-bound patients to asymptomatic carriers. Our study is unique in comparing the gene expression profiles from related affected, asympto...

A nursery epidemic caused by multidrug resistant Salmonella typhimurium is reported. In total, 21 infants developed symptomatic illness; of these, 17 had septicemia (7 blood culture positive) and 4 had diarrhea alone. Asymptomatic carrier state was identified in 13 infants. Male sex and birth asphyxia increased the risk for symptomatic illness. Fever, lethargy, and diarrhea were the most common...

The development of EBV infection and PTLD is normally associated with a high EBV load in peripheral blood. Often, children undergoing primary or reactivation of EBV infection subsequent to ITx will have chronically elevated EBV loads. To better understand this phenomenon and its consequences, we retrospectively reviewed the records of children who underwent ITx (either isolated or part of multi...

OBJECTIVES To determine the prevalence of the carrier state in household contacts in children with tinea capitis, the duration of the carrier state, factors associated with carriage, and the proportion of carriers who develop clinical disease. DESIGN Cross-sectional, cohort, prevalence study. SETTING General pediatric clinic serving an indigent, inner-city, African American population. PA...
