Methods for diagnosis of viral infection have progressed rapidly during the past two to three decades from animal inoculation to computer automation. Virus isolation, however, still remains the "gold standard." With the availability of antiviral agents, physicians now demand accurate laboratory diagnosis of their patients' illnesses in order to give proper treatment. Discovery of unknown viral ...

In connection with certain investigations being carried out in this laboratory, it was found necessary to work with sixto twelve-hour cultures of bacteria in fluid culture media. The apparatus described below was devised to obviate the need of either coming to the laboratory late in the evening to inoculate cultures for the following day's work or of wasting time waiting for cultures to grow ou...

The reasons for using sterilized pus in the place of autogenous or other vaccines are : 1. The great simplicity and cheapness. 2. The pus is truly autogenous, this is not so with vaccines prepared from organisms grown on artificial media; for the organism is changed by such growth. 3. Besides the bacteria, pus contains toxins, and antibodies both extremely useful for therapeutic inoculation. Th...

Fungi that occur inside asymptomatic plant tissues are known as fungal endophytes. Different genera of fungal entomopathogens have been reported as naturally occurring fungal endophytes, and it has been shown that it is possible to inoculate plants with fungal entomopathogens, making them endophytic. Their mode of action against insects appears to be due to antibiosis or feeding deterrence. Res...

The ever increasing movement of viruses around the world poses a major threat to plants growing in cultivated and natural ecosystems. Both generalist and specialist viruses move via trade in plants and plant products. Their potential to damage cultivated plants is well understood, but little attention has been given to the threat such viruses pose to plant biodiversity. To address this, we stud...

Two different procedures for inoculation of HSV on corneas of BALB/c mice were evaluated. The first was by the use of HSV suspensions directly on the corneas and the other was after corneal scarification. Animals by this later method presented greater morbidity and mortality than those of first group, suggesting that inoculation of HSV without scarification of the cornea should be the method of...

to evaluate the effect of different application methods of different strains of pgpr on sorghum forage production, a field experiment was conducted in research farm of college of agriculture of university of tehran in karaj during 2009. the treatments were arranged factorially and the data was analyzed based on a complete block design with three replications. the treatments comprised of three p...

The estuarine copepod Acartia tonsa naturally carried diverse strains of bacteria on its body. The bacterial community composition (BCC) remained very conservative even when the copepod was fed different axenic algal species, indicating that the food per se did not much affect BCC associated with the copepod. In xenic algal treatments, however, copepod-associated BCC differed with each alga fed...
