Comparison of the VersaTrek and BACTEC MGIT 960 systems for the contamination rate, time of detection and recovery of mycobacteria from clinical specimens

  The most commonly used conventional Lowenstein Jensen (L.J) culture method requires at least 6 to 10 weeks of incubation due to the slow growth rate of the Mycobacterium tuberculosis complex. Today, there are liquid automated systems to detect mycobacteria than faster conventional LJ culture method. In this study, we aimed to compare of the VersaTrek system and BACTEC MGIT 960 system for the...

Assessment of antifungal activity of Rumex vesicarius L. and Ziziphus spina-christi (L.) Willd. extracts against two phytopathogenic fungi

  The preliminary phytochemical screening of extracts of Rumex vesicarius L. and Ziziphus spina-christi (L.) Willd. showed the presence of compounds that are biologically active against the two root rot pathogens Drechslera biseptata and Fusarium solani in vitro. The relative efficacy of this action, however, differed according to the extracted plant, solvent used,...

A recombinant E0 gene of bovine viral diarrhea virus protects against challenge with bovine viral diarrhea virus of sika deer

  Eukaryotic expression plasmid (PVAX 1/E0) of E0 gene was constructed from an isolated strain of bovine viral diarrhea virus (BVDV) from sika deer and transfected into the BHK-21 cells to detect E0 gene transcription expression level and protein expression level. It was found that E0 gene could express in BHK-21 cells by RT-PCR and ELESA results. The humoral and cellular immune...

Impact of fungal content of some Arabic nuts to induce kidney toxicity and agonistic action of natural resources

  Human and animals are exposed to a great extent of the danger of mycotoxic infection and their toxins due to wide spread of fungal growth on grains and food. Aflatoxin B1 (AFB1) is one of the most dangerous toxins that are produced by fungi as a secondary metabolic products. This study aims to isolate and identify the fungi from some grains present in Arabian nuts. 30 samples were collected from commercial...

Virucidal activity of green propolis against avipoxvirus in chorioallantoic membrane of embryonated chicken eggs

  Recent pandemics caused by virus like influenzavirus (H1N1, H5N1) reaffirm the importance of studies aiming at obtaining new virucidal and/or antiviral substances, once its prolonged use can lead to resistance to the active principles. Green propolis, which has several scientifically proven bioactive properties, was evaluated in this study as an ethanol extract regarding its virucidal capacity...

Antimicrobial and nematicidal screening of anamorphic fungi isolated from plant debris of tropical areas in Mexico

  Forty seven fungal strains were isolated from plant debris in the tropical regions of Mexico, where fifteen of them were identified to species and twenty two to genus level. All isolates were grown in fermented rice and their EtOAc extracts screened against ten targets, four bacteria (Bacillus subtilis,Erwinia carotovora, Staphylococcus aureus and Xanthomonas campestris), the yeast Candida...

The impact of electrode reuse on the biofilm community and performance of whey-fuelled H-type microbial fuel cell

  Humankind has always been engaged in a relentless quest for energy to drive daily activities. However, most of the existing conventional strategies of tapping the environment are expensive and polluting. A nascent microbial fuel cell technology, relying on the degradation of wastewater such as cheese whey with the subsequent release of electricity, is thus the focus for sustainable energy. It is therefore...

Pollen germination, tube growth and longevity in some cultivars of Vitis vinifera L.

  The grapevines (Vitis vinifera, L.) are cultured widely in Maragheh and are made one of the most important commercial fruit crops of its regions. Most of the cultivars are growing with their fruits or are used in rasine, juice and fresh fruits forms. However, pollination is the main factor affecting fruit set and knowledge about pollen traits of cultivars is necessary to plan the vineyards establishment...

Non-steroidal anti-inflammatory drugs (NSAIDs) inhibit growth of yeast pathogens

  Studies on yeasts exposed non-steroidal anti-inflammatory drugs (NSAIDs) such as acetylsalicylic acid (aspirin) as potential anti-mitochondrial antifungals. In this study, various NSAIDs were tested for antifungal activity on the human yeast pathogens Candida albicans and Cryptococcus neoformans. Our results suggest a dual action for these drugs, that is, antifungal as well as...
