Two new species of (Auriculariales, Basidiomycota) based on morphology and DNA sequences.

In the present study, fourteen -like specimens were collected from China, France, and Australia. Based on morphological characteristics and phylogenetic analyses using the internal transcribed spacer regions (ITS) and the large subunit of nuclear ribosomal RNA gene (nLSU), four species in , including and , and two new species, and , were identified. The four species are described and illustrated in detail.

Multidisciplinary advisory teams to manage multidrug-resistant tuberculosis: the example of the French Consilium.

The World Health Organization (WHO) recommends that multidrug-resistant tuberculosis (MDR-TB) treatment should be managed in collaboration with multidisciplinary advisory committees (consilia). A formal national Consilium has been established in France since 2005 to provide a centralised advisory service for clinicians managing MDR-TB and extensively drug-resistant (XDR-TB) cases. Review the activity of the French TB Consilium since its establishment.

complex () in temperate Northern Hemisphere.

Taxonomy of the complex is revised based on morphology and two genetic markers, ITS and . In total, we recognize 24 species, multiplying the known species diversity in the complex. We provide descriptions for 20 temperate Northern Hemisphere taxa.

Safety and efficacy assessment of two new leprosy skin test antigens: randomized double blind clinical study.

Background: New tools are required for the diagnosis of pre-symptomatic leprosy towards further reduction of disease burden and its associated reactions. To address this need, two new skin test antigens were developed to assess safety and efficacy in human trials.

Methods: A Phase I safety trial was first conducted in a non-endemic region for leprosy (U.

The challenge of producing skin test antigens with minimal resources suitable for human application against a neglected tropical disease; leprosy.

True incidence of leprosy and its impact on transmission will not be understood until a tool is available to measure pre-symptomatic infection. Diagnosis of leprosy disease is currently based on clinical symptoms, which on average take 3-10 years to manifest. The fact that incidence, as defined by new case detection, equates with prevalence, i.

Rapid variable-number tandem-repeat genotyping for Mycobacterium leprae clinical specimens.

Mycobacterium leprae is the noncultivable pathogen of leprosy. Since the genome sequence of an isolate of M. leprae has become available, multiple-locus variable-number tandem-repeat (VNTR) analysis (MLVA) has been explored as a tool for strain typing and identification of chains of transmission of leprosy.

Multiple polymorphic loci for molecular typing of strains of Mycobacterium leprae.

The need for molecular tools for the differentiation of isolates of Mycobacterium leprae, the organism that causes leprosy, is urgent in view of the continuing high levels of new case detection, despite years of aggressive chemotherapy and the consequent reduction in the prevalence of leprosy. The slow onset of leprosy and the reliance on physical examination for detection of disease have restricted the epidemiological tracking necessary to understand and control transmission. Two genetic loci in several isolates of M.

Aerosols and anti-infectious agents.

Anti-infectious agents such as pentamidine, antibiotics (mainly colistine and aminoglycosides), and amphotericin B can be administered by aerosol. Apart from pentamidine and Tobi, this route of administration is not officially approved and it constitutes an empirical approach, which has benefited from recent research summarized hereafter. The most fundamental question is related to the potentially deleterious effects of nebulization processes, especially ultrasound, on the anti-infectious properties of the drugs.

Measurement of canine IgE using the alpha chain of the human high affinity IgE receptor.

In vitro assays for allergen specific immunoglobulin E (IgE) are a convenient and reproducible alternative to intradermal skin testing in dogs. Such tests may be used to support a diagnosis of atopic dermatitis and to define appropriate allergens for immunotherapy. Current in vitro assays rely upon monoclonal or polyclonal antibodies as IgE detection reagents.

Characterization and cloning of a major high molecular weight house dust mite allergen (Der f 15) for dogs.

Although house dust mites (HDM(s)) are important elicitors of canine allergy, the low molecular weight molecules defined as major allergens for humans do not appear to be major allergens for dogs. Western blotting of Dermatophagoides farinae (D. farinae) extracts with sera from sensitized dogs showed that the majority of animals had IgE antibodies specific for two proteins of apparent molecular weights of 98 and 109kDa (98/109kDa).

[Anti-infective aerosols].

Anti-infectious agents such as pentamidine, antibiotics (mainly colistine and aminoglycosides) and amphotericin B can be administered by aerosol. This route of administration is not officially approved and it constitutes an empirical approach which has benefited from recent research which is summarized hereafter. The most fundamental question is related to the potentially deleterious effects of nebulization processes, especially ultrasound, on the anti infectious properties of the drugs.

Induction of Th1 cytokine responses by mycobacterial antigens in leprosy.

Twelve mycobacterial antigens were compared for induction of gamma interferon (IFN-gamma) secretion by human blood mononuclear cells of patients with leprosy. Fractionated Mycobacterium leprae antigens containing cell wall proteins or cytosolic and membrane proteins induced good IFN-gamma responses in tuberculoid leprosy patients. Lipoarabinomannan from M.

Deposition of amphotericin B aerosols in pulmonary aspergilloma.

The aim of the present study was to characterize amphotericin B aerosols nebulized by ultrasonic and jet nebulizers and to study their deposition and pharmacokinetics in patients with pulmonary mycetoma. The aerodynamic behaviour and pulmonary deposition of amphotericin B particles were measured using a direct isotopic method based on stable labelling of the drug with 99mTc. Each nebulizer was bench tested for inhaled mass and particle size distribution.

Characterization of the gene encoding the immunodominant 35 kDa protein of Mycobacterium leprae.

Analysis of the interaction between the host immune system and the intracellular parasite Mycobacterium leprae has identified a 35 kDa protein as a dominant antigen. The native 35 kDa protein was purified from the membrane fraction of M. leprae and termed MMPI (major membrane protein I).

[Chronic course of reactive bronchial dysfunction syndrome. Apropos of 6 further cases].

The reactive airways dysfunction syndrome (RADS) occurs as a persistent bronchial hyper-reactivity with asthmatic-type dyspnoea and occurs after a single and massive inhalation of irritant gases, smoke or vapours, in subjects who had previously had no respiratory disease. We report six cases in patients without any previous asthmatic history or history of atopy who had developed RADS after being exposed to different irritants. The symptoms evolved over 5-84 months after the initial accident.

Purification, characterization, gene sequence, and significance of a bacterioferritin from Mycobacterium leprae.

The study of tissue-derived Mycobacterium leprae provides insights to the immunopathology of leprosy and helps identify broad molecular features necessary for mycobacterial parasitism. A major membrane protein (MMP-II) of in vivo-derived M. leprae previously recognized (Hunter, S.

Chemical definition, cloning, and expression of the major protein of the leprosy bacillus.

The decline in prevalence of leprosy is not necessarily matched by a fall in incidence, emphasizing the need for new antigens to measure disease transmission and reservoirs of infection. Mycobacterium leprae obtained from armadillo tissues was disrupted and subjected to differential centrifugation to arrive at preparations of cell wall, cytoplasmic membrane, and cytosol.
