[Atmospheric concentration of fungus spores in Ankara and the effect of meteorological factors in 2003 period].
(2009-10-01T00:00:00Z) Ceter, Talip; Pinar, Nur Münevver
The atmospheric concentrations of airborne fungus spores change continuously according to the meteorological factors, and their intensity have important allergic effects on atopic subjects and opportunistic pathogenic effects on immunocompromised patients. The aim of this study was to identify the fungal spores found in Ankara atmosphere during 2003 period and to investigate the changes in spore concentrations in relation to meteorological factors. Fungal spores were sampled by using 7-day Burkard volumetric trap between January to December 2003, and probable identification was performed microscopically based on their morphological structures. A total of 433.079 spores/m3 belonging to 35 taxa were observed during the study. The rates of these taxa were as follows; 75.5% Cladosporium, 6.1% Alternaria, 2.2% Leptosphaeria, 2.2% Ustilago, 2.1% 1-septate ascospores, 2% Exosporium, 1.6% Pleospora, and 1.3% Drechslera. The other taxa with concentrations < 1% have consisted a total of 7.1% of all atmospheric spores (Puccinia, Curvularia, Coprinus, Nigrospora, Periconia, Melanomma, Torula, Ascobolus, Agrocybe, Pithomyces, Stemphyllium, Ganoderma, Boletus, Peronospora, Venturia, Paraphaeosphaeria, Epicoccum, Didymella, Chaetomium and Fusarium rates between 0.7-0.1%; Oidium, Xylaria, Botrytis, Melanospora, Dictyosporium, Sporormiella and Tetracoccosporium rates between 0.09-0.01%). Although fungal spores were detected in all months in Ankara atmosphere, the evaluation of the seasonal distribution of spore concentrations revealed that the highest value was detected in July (100.697 spores/m3), while the lowest value was in January (4268 spores/m3). When the effects of meteorological factors on spore concentrations were investigated, it was found that, monthly mean temperature (> 20 degrees C) has a strong positive correlation (p < 0.01), and monthly mean relative humidity (< %50) and precipitation (0-20 mm) have strong negative correlations (p < 0.01) on the spore concentrations, while wind velocity (3 m/s) has a slightly positive effect. An annual spore calendar which indicated weekly concentrations and allergenicity levels of those identified fungal spores, was also prepared in this study. In conclusion, it is expected that these data would be helpful for the researchers in the area of aeropalinology and for the clinicians to evaluate allergic diseases.
[Investigation of antifungal activity of Ononis spinosa L. ash used for the therapy of skin infections as folk remedies].

Traditional folk remedies used for centuries come up focus of interest in recent years, due to the trend of use of herb-derived natural products. In addition, increasing morbidity and mortality rates of opportunistic fungal infections and accelerating antifungal resistance rates of fungi lead to the use of alternative therapies with herb-derived preparations as novel antifungals. Ononis spinosa L. (spiny restharrow), which is classified in Leguminosae family, is one of the plants used in herbal medicine as folk remedies for the treatment of skin lesions and/or infections as well as many other disorders. Antibacterial, antifungal, anti-inflammatory and analgesic effects of Ononis spinosa (OS) have already been supported by different studies. The roots and aerial sections of OS are the mainly employed parts for application, however local communities inhabiting at southeastern parts of Anatolia, Turkey, employ the ashes of OS widely to heal the skin infections. There have been no reports about the antifungal activity of OS ashes as far as the current literature is concerned. The aim of this study was to investigate the antifungal activity of ashes of OS, collected from a rural area located at Southeast Anatolia. Ashes of OS have been obtained by burning the plant samples at 400°C, and extracted in sterile distilled water and ethanol. The efficacy of aqueous and ethanol extracts of OS ashes were tested against 10 fungi, of which one was a Candida albicans standard strain (ATCC 95071) and the others were clinical isolates (C.albicans, Candida glabrata, Candida tropicalis, Candida krusei, Candida guilliermondii, Candida parapsilosis, Candida pelliculosa, Trichosporon asahii, Trichophyton rubrum). Antifungal susceptibility test was performed by disc diffusion (DD) method and the results were confirmed with minimum inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) values determined by microdilution method. The results indicated that both aqueous and ethanol extracts of OS ash showed antifungal activity against C. Albicans ATCC 95071 (DD inhibition zones were 16 and 15 mm, respectively; MIC = 1.25 µg/ml, MFC = 1.25 µg/ml), whereas against C.glabrata clinical isolate only ethanol extract exhibited antifungal activity (DD inhibition zone = 10 mm, MIC = 5.00 µg/ml, MFC = 40.00 µg/ml). No antifungal effect was detected against the other clinical Candida spp, T.asahii and T.rubrum isolates. In conclusion, since our results emphasize that extracts of OS ash that traditionally used for skin disorders, showed promising degrees of antifungal activity against some of Candida strains, these preliminary data should be supported by further large-scale studies.
Morphological features of Bundleia spp. (Ciliophora: Entodiniomorphida: Buetschliidae) and ontogenesis in Bundleia Cunha and Muniz 1928
(2014-12-01T00:00:00Z) Gürelli, Gözde; Göçmen, Bayram
The aim of this study was to investigate the morphological features of 7 endocommensal ciliates, B. (s. str.) postciliata, B. (s. str.) piriformis, B. (s. str.) nana, B. (C.) elongata, B. (C.) triangularis, B. (F.) dolichosoma, and B. (F.) inflata belonging to the genus Bundleia, which exist in the hindgut of 15 Rahvan horses and 15 racing horses living in the vicinity of Izmir and to investigate the ontogenesis in the Bundleia genus.
