Wolbachia bacteria are ubiquitous intracellular bacteria of arthropods. Often considered reproductive parasites, they can benefit certain host species. We describe a new Wolbachia strain from Leptopilina victoriae, a Drosophila wasp. The strain is closely related to Wolbachia from Culex sp. Located to the posterior poles of oocytes, it manipulates its host's reproduction by inducing a male deve...

Pollen from the Acacia has been reported as an important source of pollinosis in tropical and subtropical regions of the world. The aim of this study was to characterize the IgE binding protein of Acacia farnesiana pollen extract and evaluate cross-reactivity with the most allergenic pollens. In this study, pollen extract was fractionated by SDS-PAGE and the allergenic profile was determined by...

Exploiters of protection mutualisms are assumed to represent an important threat for the stability of those mutualisms, but empirical evidence for the commonness or relevance of exploiters is limited. Here, I describe results from a manipulative study showing that an orb-weaver spider, Eustala oblonga, inhabits an ant-acacia for protection from predators. This spider is unique in the orb-weaver...

The aim of this study is to determine the effect of methanol crude leaves extract and aqueous fraction of Acacia nilotica on liver enzymes and lipid profiles of alloxan induced diabetic Wistar rats. Diabetes was induced by a single intraperitoneal injection of alloxan dissolved in 0.9%v/v cold normal saline solution at a dose of 150 mg/kg body weight, after which the rats were randomly divided ...

Xanthomonas axonopodis punicae is the causative agent of Bacterial blight of Pomegranate that is known to cause yield loss up to 70-90%. The primary disease management method involves mainly use of chemical pesticides. In present investigation the antibacterial activity of extracts of Acacia nilotica, Datura metel, cow urine and butter milk against Xanthomonas axonopodis punicae was studied by ...

Double-stranded (ds)RNA fungal viruses are currently assigned to six different families. Those from the family Totiviridae are characterized by nonsegmented genomes and single-layer capsids, 300-450 Å in diameter. Helminthosporium victoriae virus 190S (HvV190S), prototype of recently recognized genus Victorivirus, infects the filamentous fungus Helminthosporium victoriae (telomorph: Cochliobolu...

Study was aimed to evaluate the possible antisecretory and antiulcer activity of crude bark extract of Acacia catechu and its action against indomethacin an non steroidal anti inflammatory drug (NSAID) plus pyloric ligation induced gastric ulcers in rats. Administration of crude extract of Acacia catechu (400mg/kg/day p.o.) significantly reduced ulcer index when compared with indomethacin induc...

The immunomodulatory effect of aqueous extract of Acacia catechu commonly known as Katha or Karangali was studied at two doses of 5 mg/kg and 50 mg/kg orally. The effect was studied in neutrophil adhesion test, mice lethality test, carbon clearance assay, cyclophosphamide induced neutropenia, serum immunoglobulin levels and the heamagglutination test. Acacia catechu extract showed an increase i...

Intraand inter-specific competition between seedlings of Acacia etbaica Schweinf. and the grass Hyparrenia hirta (L.) Stapf. was studied to evaluate the influence of the perennial grass on the establishment of the tree seedlings. The experiment was conducted using a replacement series in which plants were grown in a greenhouse at an overall density of six individuals per pot, providing combinat...

Germination is the first stage in plant life cycle confronted with soil salinity and because of expanded saline areas around the world it is important to determine salt effects on this stage. In this study, we report an in vitro procedure for studying germination of Acacia spp. under salt stress with different NaCl and KCl concentrations. Seeds of Acacia tortilis (Forssk.) Hayne and Acacia oerf...
