“…Similar results were seen in study conducted by Moharram et al who in their study on 124 patients found that the disease was more prevalent among persons between 21 to 30 years. 4 Aneja et al in their study found the disease to be more prevalent in females than males in the age group of 31 to 40 years. 5 In the present study most (46.1%) of the patients reported to us in the summer season indicating seasonal preponderance of the disease.…”

Background: Kashmir valley witnessed devastating floods in the month of September 2014. The target of the study was to assess the changes in clinical profile of otomycosis and fungi responsible for the disease, in-vitro sensitivity of different fungi to various commercially available antimycotic solutions and clinical efficacy of various topical antimycotic solutions in otomycosis in pre and post flood period.Methods: This study was conducted in the Department of ENT, GMC, Srinagar from February 2014 to July 2015. 152 clinically suspected otomycosis patients were subjected to mycological tests to identify the organism. Clotrimazole, terbinafine, lulliconazole, sertaconazole and combination of 1% clotrimazole, chloramphenicol, beclomethasone was given randomly in equal number of these patients and were followed for 4 weeks. Results of different antifungals were evaluated clinically. Results: The trend varies in pre and post flood period. Candida albicans was the most common organism isolated in pre-flood period whereas Aspergillus flavus was the most common organism isolated in post flood period. In the pre flood period Candida and Aspergillus species had equal rate of isolation. However, in post flood period Aspergillus was most common species isolated. Effect of lulliconazole and terbinafine was same in pre and post flood time but serticonazole and fluconazole showed slight variation in effectiveness in post flood period. Clotrimazole and combination of 1% clotrimazole, chloramphenicol and beclomethasone were least effective post flood.Conclusions: Flood had its impact on profile of otomycosis. A. flavus became more common species in post flood period. It was observed that flood had some impact on drug treatment too but further studies and tests are needed to confirm the effectiveness of drugs on treatment of otomycosis.

Assessment of biodegradation in ancient archaeological wood from the Middle Cemetery at Abydos, Egypt

et al. 2019

View full text Add to dashboard Cite

Abydos is a large, complex archaeological site located approximately 500 km south of Cairo in Upper Egypt. The site has served as a cemetery for thousands of years and is where most of the Early Dynastic royal tombs are located. North Abydos includes the Middle Cemetery and the North Cemetery, which are separated from each other by a wadi. The Middle Cemetery was the burial ground for important Sixth Dynasty (2407–2260 BC) officials and over time for thousands of elite and non-elite individuals as well. Excavations at the core area of the Old Kingdom mortuary landscape have revealed many culturally important wooden objects but these are often found with extensive deterioration that can compromise their preservation. The objectives of this study were to characterize the biodegradation that has taken place in excavated wooden objects, elucidate the type of wood degradation present, obtain information on soil properties at the site and identify fungi currently associated with the wood and soils. Light and scanning electron microscopy studies were used to observe the micromorphological characteristics of the wood, and culturing on different media was done to isolate fungi. Identification of the fungi was done by examining morphological characteristics and extracting rDNA from pure cultures and sequencing the ITS region. Wooden objects, made from Cedrus , Juniperus and Acacia as well as several unidentified hardwoods, were found with extensive degradation and were exceedingly fragile. Termite damage was evident and frass from the subterranean termites along with sand particles were present in most woods. Evidence of soft rot attack was found in sections of wood that remained. Fungi isolated from wood and soils were identified as species of Aspergillus , Chaetomium , Cladosporium , Fusarium , Penicillium , Stemphylium Talaromyces and Trichoderma . Results provide important information on the current condition of the wood and gives insights to the identity of the fungi in wood and soils at the site. These results provide needed information to help develop conservation plans to preserve these degraded and fragile wooden objects.

“…This result is consistent with the observation Aihetasham et al (2015) indicated that the A. parasiticus has repellent effect against the workers of Coptotermes heimi. Moharram, et al (1992) isolated A. niger from P. hypostoma workers.…”

This study is conducted to determine the effect of entomopathogenic fungi Metarhiziuim anisopliae (M. ani), Beauveria bassiana (B.bas) and Aspergillus niger (A.niger) in some aspects subterrenene termites life under laboratory and field conditions. After one week of treatment there was significate difference among concentrate 4×106 and concentrates 2×106 and 1×106 but no significate difference among concentrates 2×106 and 1×106 of all treatments. In addition to there was significant difference among M.anisopliae and other fungi B.bassiana (Ballsamo) and A.niger, The fungi M.ansiopliae more effectiveness than B.bassiana and A.niger which the mortality rates were 22.5%, 15.0% and 13.3% to M.ansiopliae , B.bassiana and A.niger respectively. The LC50 for three fungi were 3.278×106, 4.6526×106 and 5.4982×106 for M.anisopliae, B.bassiana and A.niger, respectively. The higher concentrations 2×106spores/ml and 4×106 spores/ml the reduction percentages were 25.93, 19.43 and 11, 85% for 2×106 spores/ml and 61.52, 35.54 and 20.06% at 4×106 spores/ml for A.niger, B.bassiana and M.anisopliae, respectively. The run-down in the reduction % in treated traps with M. anisopliae concentrations of may be due to this reason. The reduction percentages for trap treated with concentrations of A. niger were height due to not attack by workers, due to the fungi A. niger has a repellent or an antipathetic effect to worker.
