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...

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...

Evaluation of different pH and temperatures for bacterial cellulose production in HS (Hestrin-Scharmm) medium and beet molasses medium
Acetobacter pasteurianus HBB6 and Acetobacter lovaniensis HBB5 strains used in this study was isolated from vinegar in Turkey. Bacterial cellulose was produced from HS (Hestrin-Scharmm) medium and beet molasses using A. pasteurianus HBB6 and A. lovaniensis HBB5. In this study, the effects of different pH (2.5, 3.5, 4.5, 6.5, 7.5 and 8.5) and temperatures (4, 22, 30 and...

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...

Does borna disease virus (BDV) have a role in the etiopathogenesis of schizophrenia?
In human, certain serological and molecular trials estimated an association between psychiatric diseases, particularly schizophrenia, mood disorders and borna disease virus (BDV). The purpose of this study was to investigate whether BDV has association with etiopathogenesis of schizophrenia. A total of 207 patients who were diagnosed with residual schizophrenia and 51 patient control grop with 134 healthy...

Emergence of extensive drug-resistant Acinetobacter baumannii in North of Jordan
The aim of this study is to investigate the antimicrobial susceptibility profile of Acinetobacter baumannii and the contribution of the insertion sequence upstream of ampC β-lactamase on the susceptibility profile of 64 A. baumannii clinical isolates collected from a Jordan hospital. A total of 64 consecutive clinical isolates of A. baumannii were recovered (between March...

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...

Trichosporon identification methods for isolates obtained from different clinical specimens
Trichosporon is a medically important genus that includes the causative agents of both deep-seated, mucosa-associated infection and superficial infection. In this study, we aimed to present data on the phenotypic and molecular identification of Trichosporon species recovered from various clinical specimens representing both superficial and systemic infections. 397 samples (65 blood cultures, 192 nail...
