Isolation, genetic diversity and identification of a virulent pathogen of eriophyid mite, Aceria guerreronis (Acari: Eriophyidae) by DNA marker in Karnataka, India
Aceria guerreronis is a serious pest of coconut in India. Investigations were carried out to investigate fungal pathogens infecting the eriophyid mites for their utilisation as biocontrol agents in Karnataka, India. The fungal pathogens namely, Hirsutella thompsonii, Beauveria bassiana, Fusarium semitectum and few opportunistic pathogens namely, Fusarium...

Molecular cloning of HSP17 gene (sHSP) and their differential expression under exogenous putrescine and heat shock in wheat (Triticum aestivum)
Polyamines (PAs) are low molecular weight ubiquitous nitrogenous compounds found in all the living organisms, which have been implicated in the expression of various stress-proteins against the abiotic stresses. Small heat shock proteins (sHSPs) are of particular importance in the thermotolerance and have been reported to act as molecular chaperones preventing denaturation or aggregation of the target...

Distribution of red blood cell antigens in drug-resistant and drug-sensitive pulmonary tuberculosis
Tuberculosis (TB) is still a widespread world infectious disease. Mycobacterium tuberculosis kills more people than any other single pathogen, with an estimated one-third of the world's population being infected. According to the World Health Organization (WHO), two billion people are infected with the causative bacillus ofMycobacterium tuberculosis. Tuberculosis is rather prevalent in...

Characterization of Aspergillus species associated with commercially stored triphala powder
About 82 triphala powder samples were analyzed for the association of different fungi. Results reveal the predominance of Aspergillus as the major genera with six predominant species namely, A. niger, A. flavus, A. fumigatus, A. terreus, A. nidulansand A. amstelodami. Therefore, these six isolated Aspergillus species were characterized morphologically, microscopically and...

The role of the yeast as probiotic in protection against liver injury
Saccharomyces cerevisiae is a well known yeast used safely from ancient times in many biotechnological applications. Nowadays, there is an increasing interest in using yeast as probiotic. Dimethyl nitrosamine (DMN) has been used to induce liver fibrosis in rats. Yeast has been used side by side with the DMN to evaluate the role of its use as a probiotic in the protection against liver fibrosis. Six...

Screening of antibacterial and antifungal activities in green and brown algae from the coast of Sidi Bouzid (El Jadida, Morocco)
Six organic extracts prepared with different solvents (methanol, acetone, hexane, chloroform and dichloromethane-methanol) and aqueous extract of 27 species of marine algae belonging to the Chlorophyta and Phaeophyta were studied for antibacterial and antifungal activities against pathogenic microorganism: eight Gram-positive bacteria: Bacillus cereus, Bacillus thuringiensis, Bacillus subtillus,...

Effect of mobile phone emitted radiation on the power frequency and amplitude of electroencephalographic (EEG) activity in rats
The aim of the present study was to investigate the effect of mobile phone (MP) (935.2 – 960 MHz, 0.35 mW/cm2) on the power frequency and amplitude of electrocorticographic ECoG recording. The brain cortex of anaesthetized rats were exposed to electromagnetic fields (EMFs) emitted from a mobile phone 2 h daily for one week and ECoG recording were carried out through trephine openings in the skull. The...

Biocontrol of bacterial spot diseases of muskmelon using Paenibacillus polymyxa G-14
Paenibacillus polymyxa strain G-14 (PpG14) isolated from the muskmelon rhizosphere, produces antibiotic(s) that are active against Pseudomonas syringae pv.lachrymans and Acidovorax avenae subsp. citrulli (two pathogens that cause bacterial spot diseases). Strain G-14 strongly inhibited the growth of Pseudomonas...

Arsenic levels in groundwater aquifer of the Neoplanta source area
As part of a survey on the groundwater aquifer at the Neoplanta source site, standard laboratory analysis of water quality and an electromagnetic geophysical method were used for long-term quantitative and qualitative monitoring of arsenic levels. This study presents only the results of research conducted in the Neoplanta-Koteksprodukt zone for 2005 and 2008 for the purpose of comparison of water quality at...
