Induced oxidative stress by Metarhizium anisopliae spp. instigates changes in lipid peroxidation and ultra structure in Periplaneta Americana

  Consequent to injection of conidia at LC30, LC50 and LC90 doses of the entomopathogenic fungal isolates of Metarhizium anisopliae (Metch.), alterations in lipid peroxidation and ultrastructural changes were observed in cockroaches (Periplaneta americana). A decrease in the level of lipid peroxidation was evident in the treated cockroaches compared to those of control. Present investigation reports...

Developments in using fatty acids in fungal chemotaxonomy

  The cellular fatty acid composition of nine species of Fusarium; namely, Fusariumanthophilum, F. avenaceum, F. cerealis, F. graminearum, F. graminum, F. oxysporum f. sp. conglutinans, F. pseudograminearum, F. roseum and F. sacchari var. elongatumgrowing on malt extract medium were determined. The fatty acid profiles of...

Escherichia coli from Nigeria exhibit a high prevalence of antibiotic resistance where reliance on antibiotics in poultry production is a potential contributing factor

  To assess the prevalence of antibiotic resistance in Nigeria, single Escherichia coliisolates were collected from a geographically diverse panel of fecal samples collected from human clinical and non-clinical donors (n=77), livestock (cattle, swine, and goats) and chickens (n=71 total). There was no difference in the proportion of isolates resistant to ≥1 antibiotics from human clinical and...

Environmental influence on cultivable microbial community in the sediment of Sundarban mangrove forest, India

  In the Sundarban Mangrove forest, microbial activities are dominantly involved both in the mineralization and decomposition processes that regulate nutrient profile of sediment of different depth. It was found that besides changing the water and sediment quality, monsoonal cycle plays a crucial role to regulate microbial population distribution in the mangrove sediment. Statistical analysis revealed that...

Structural characterization and biological activity of exopolysaccharide from Lysinibacillus fusiformis

  The exopolysaccharide (EPS) of Lysinibacillus fusiformis were evaluated for their antioxidant properties. The total antioxidant capacity of EPS extracts was found to be maximum in malt medium 80.13 ± 0.26%. The hydrogen peroxide radical scavenging activity was found to be maximum in malt medium 78.3 ± 0.26%. The DPPH radical scavenging activity was found to be maximum in malt medium...

Helicobacter pylori and eye diseases in an Iranian hospital

  There is evidence of Helicobacter pylori infection that induces eye diseases. This study was done to find if there is any association between H. Pylori and ocular diseases, and if there is any difference in color of eye among them. Of all the 35 patients tested for biopsy with positive H. pylori, 23 (65.7%) were females and 12...

New record of twig blight on Catharanthus roseus in India

During post rainy season 2011, twig blight disease symptoms were observed on Catharanthus roseus. Symptoms appeared as dark brown to black girdling lesions on the twigs. Acervuli containing masses of spores and dark setae were observed within lesions. On the basis of fungal morphology and completion of Koch’s postulates, the pathogen was identified as Colletotrichum gloeosporioides (Penz.)...
