Main problem for Mycobacterium tuberculosis growth is time. This study evaluates the performance of Bact/Alert 3D system for isolates and identification of mycobacteria. 100 clinical specimens from the chest and tuberculosis department were included. All were positive by Lowenstein Jensen (LJ) media in different time. All samples were also tested by Bact/ALERT 3D system for time management stud...

BACKGROUND This study aimed to compare the prevalence of Mycobacterium tuberculosis complex (MTBc) lineages between direct genotyping (on sputum) and indirect genotyping (on culture), to characterize potential culture bias against difficult growers. METHODOLOGY/PRINCIPAL FINDINGS Smear-positive sputa from consecutive new tuberculosis patients diagnosed in Cotonou, (Benin) were included, befor...

This study evaluated the necessity and the contribution of solid media when used in conjunction with radiometric Middlebrook 7H12 (BACTEC 12B; Becton Dickinson, Towson, Md.) medium for recovery and complete identification of mycobacteria. Each of 1,184 digested, decontaminated respiratory specimens was inoculated into one BACTEC 12B vial, one 7H11 plate, and two Lowenstein-Jensen (LJ) slants. W...

BACKGROUND Tuberculosis kills more people than any other infectious disease, and new regimens are essential. The primary endpoint for confirmatory phase III trials for new regimens is a composite outcome that includes bacteriological treatment failure and relapse. Culture methodology is critical to the primary trial outcome. Patients in clinical trials can have positive cultures after treatment...

Nontuberculous mycobacteria (NTM), important organisms in the Genus Mycobacterium and commonly present in the environment, are known to cause disseminated disease in AIDS patients. In this study, NTM were isolated from environment (soil and water) of the AIDS patients with disseminated NTM disease to know the prevalence of environmental NTM species and their correlation with clinical isolates f...

We report here a case of giant vulval condyloma in a two-year-old infant infected by her "baby sitter" without sexual abuse. Treated by surgical excision coupled with electrocoagulation, it was noted a rapid recurrence two weeks after treatment requiring a second electrocoagulation session. More than a year later, no lesion was noted, thus demonstrating therapeutic success. The unavailability o...

In the context of topcolor-assisted techicolor(TC2) models, we study the contributions of the neutral top-pion π t to the lepton flavor violating(LFV) processes li → ljγ and li → lj lkll. We find that the present experimental bound on μ → eγ gives severe constraints on the free parameters of TC2 models. Taking into account these constraints, we consider the processes li → lj lkll generated by t...

Recent research suggests that emotions can have a central role in decision making in a number of contexts. These contexts range from work tasks and moral behaviour (e.g. Baumeister, Stillwell & Heatherton, 1994), social judgements and social behaviour (e.g. Forgas, 2000) to consumption (e.g. Lerner, Small, & Lowenstein, 2004). The context of ethical consumption – defined as consumption that ent...
