This is a first case of Trichophyton soudanense isolated from Ivoiran student in Tunisia. A 24-year-old man was addressed for extensive erythematous, scaling lesions. Examination
disclosed tinea capitis, tinea corporis, tinea pedis, and onychomycosis of toenails and fingernails. Isolates were identified
as Trichophyton soudanense on the basis of macroscopy and microscopy colony characteristics. The patient was treated with fluconazole, topical econazole,
and ciclopiroxolamine varnish. Although T. soudanense was identified since the late 1950s outside the African continent especially in the North America, Brazil, Australia, and
many European countries, this is the first case reported in Tunisia. Accessibility to our universities for African students
makes possible the emergence of this dermatophyte. 相似文献

Introduction
Bacteria and/or their antigens have been implicated in the pathogenesis of reactive arthritis (ReA). Several studies have reported the presence of bacterial antigens and nucleic acids of bacteria other than those specified by diagnostic criteria for ReA in joint specimens from patients with ReA and various arthritides. The present study was conducted to detect any bacterial DNA and identify bacterial species that are present in the synovial tissue of Tunisian patients with reactive arthritis and undifferentiated arthritis (UA) using PCR, cloning and sequencing.Methods
We examined synovial tissue samples from 28 patients: six patients with ReA and nine with UA, and a control group consisting of seven patients with rheumatoid arthritis and six with osteoarthritis (OA). Using broad-range bacterial PCR producing a 1,400-base-pair fragment from the 16S rRNA gene, at least 24 clones were sequenced for each synovial tissue sample. To identify the corresponding bacteria, DNA sequences were compared with sequences from the EMBL (European Molecular Biology Laboratory) database.Results
Bacterial DNA was detected in 75% of the 28 synovial tissue samples. DNA from 68 various bacterial species were found in ReA and UA samples, whereas DNA from 12 bacteria were detected in control group samples. Most of the bacterial DNAs detected were from skin or intestinal bacteria. DNA from bacteria known to trigger ReA, such as Shigella flexneri and Shigella sonnei, were detected in ReA and UA samples of synovial tissue and not in control samples. DNA from various bacterial species detected in this study have not previously been found in synovial samples.Conclusion
This study is the first to use broad-range PCR targeting the full 16S rRNA gene for detection of bacterial DNA in synovial tissue. We detected DNA from a wide spectrum of bacterial species, including those known to be involved in ReA and others not previously associated with ReA or related arthritis. The pathogenic significance of some of these intrasynovial bacterial DNAs remains unclear. 相似文献73.

A pot experiment was conducted to investigate the effect of nickel concentration on physiological characteristics of Alyssum murale when grown in a soil mixed with sewage sludge (at the rate of 2.8%). Two types of sludge were used: agricultural sewage sludge (S1) and industrial sewage sludge with an increasing nickel concentration (S2, S3, and S4). Results showed that Ni in shoots was higher than Ni in roots. A. murale is able to concentrate up to 12730 mg/kg Ni in leaves. The highest dry matter yield was observed with plants grown with agricultural sewage sludge. An addition of S2 and S3 increased shoot biomass. However, application of S4 reduced 40% shoot dry weight as compared to the control Ni treatment did not affect all chlorophyll fluorescence parameters. The F(v)/F(m) ratio was stable between Ni treatments. Photosynthesis rate (A) increased with agricultural sewage sludge, but remained stable with variable Ni rates from the industrial sludge. The chlorophyll content increased with S1, S2 and S3 but it remains constant with S4 when compared to the control Therefore, high nickel concentration did not affect the function of the photosynthetic machine of A. murale. 相似文献

This is the first case of Microsporum ferrugineum isolated from a Tunisian patient. A 60-year-old man was admitted for tinea sycosis associated with circinate herpes of the
hand. Examination disclosed diffuse erythematic and perifollicular papules and pustules in the beard area. Typical ringworm
vesiculo-pustular lesions involved skin of the hand. Isolates were identified as Microsporum sp on the basis of macroscopic and microscopic colony characteristics. The diagnosis of M. ferrugineum was confirmed by PCR sequencing of Chitin Synthase1 gene. The patient was treated successfully with Griseofulvin, which was
administered for 4 weeks. 相似文献

Activation of cellular proto-oncogenes can be detected in several human cancers. In the current study, alterations of C-erb B2 gene in primary human breast cancers were investigated. It was found to be amplified from 2 to 30 fold in 25% of the tumors. Correlations of gene amplification with several disease parameters was evaluated. 相似文献

An argyrophil stain for nucleolar organizer regions (NORs) has been applied to paraffin sections of 24 malignant and 3 benign breast tumors. It was found that the total number of Ag-NORs in malignant breast lesions (3.66) significantly exceeded those in benign lesions (1.65). Relationship between this index and some clinical parameters was studied. A positive correlation between NORs and histological grading and prognostic was found. 相似文献
