Fungi can be found throughout the world. They may live as saprophytes, parasites or symbionts of animals and plants in indoor as well as outdoor environment. For decades, fungi belonging to the ascomycota as well as to the basidiomycota have been known to cause a broad panel of human disorders. In contrast to pollen, fungal spores and/or mycelial cells may not only cause type I allergy, the mos...

A counterimmunoelectrophoresis test for Pneumocystis carinii antigenemia was employed to assess the extent of subclinical infection or colonization with this agent in adults with infection, pulmonary disease, or malignancy and in healthy homosexual men. Antigenemia was detected in 6 of 208 (3%) of normal controls, 3 of 28 (11%) of patients with pulmonary infection, 3 of 33 (9%) of those with ch...

Isolates of Fusarium were discovered in peat soil samples collected from peat swamp forest, waterlogged peat soil, and peat soil from oil palm plantations. Morphological characteristics were used to tentatively identify the isolates, and species confirmation was based on the sequence of translation elongation factor-1α (TEF-1α) and phylogenetic analysis. Based on the closest match of Basic Loca...

Nocardia is a gram positive, aerobic branched actinomycete; it is an ubiquitous soil saprophyte. As an infecting agent it has been increasingly identified in humans, especially in immuno-suppressed hosts. Nocardia as a cause of septic arthritis is very unusual. The described genus was Nocardia asteroides in nearly all previously reported cases. We report an unusual case of spontaneous Nocardia ...

Aspergillus fumigatus is a filamentous fungal saprophyte that is ubiquitous in the environment. It is also a human pathogen and induces allergenic response, negatively impacting health care and associated costs significantly around the world. Much of the basic biology of this organism is only poorly understood, but the recent completion and publication of its genome sequence provides an excelle...

INTRODUCTION Alternaria is a common saprophyte, which is usually not pathogenic in humans. Generally, local wounds infections of Alternaria occur with presence of immunosuppression factors such as HIV infection and renal transplant patients. CASE PRESENTATION We reported a case of wound infection induced by Alternaria spp. in a renal transplant patients. The main interest in this case was the...

Our understanding of leptospiral pathogenesis, which remains poorly understood, depends on reliable genetic tools for functional analysis of genes in pathogenic strains. In this study, we report the first demonstration of conjugation between Escherichia coli and Leptospira spp. by using RP4 derivative conjugative plasmids. The DNA transfer described here was due to authentic conjugation, as sho...

Whiteflies (Bemisia tabaci) are a serious threat to tomato (Solanum lycopersicum) yield and production since all varieties highly susceptible this insect. The wild Solanum pennellii shows resistance towards whiteflies infestation due the high contents of acylsugars presents in its leaflets, which is not observed S. lycopersicum. Thus, plants from F2BC2 population derived cross between cultivar ...

Dienes and Edsall (1937) isolated a strain ofmycoplasma from a patient with a Bartholin's gland abscess, and this became a prelude to numerous studies in which attempts were made to demonstrate the aetiological significance of mycoplasmata in inflammatory conditions of the lower genito-urinary tract, including particularly non-gonococcal urethritis (NGU). However, the results obtained were wide...
