The physiolgical requirements of Australian isolats of four species of cytophaga/Flexibacter-like bacteria(CFLB) , namely Cytophaga Johnsonae (CJ), Cytopha Psychrophila (CP), Flexibacter Columnaris (FC) and Flexibacter maritimus (FM) were studied. Also, the pathogenesis and chemotherapy of some diseases caused by these bacteria were investigated. In vitro responses of the organisms to environmental conditins, including temperature , salinity and PH, showed that all species ha ...

This study deals mainly with taxonomy of bacteria isolated from rhizosphere of some important crops as well as from diseased plant materials. Greater emphasis was given to the identification of bacteria. Besides this, the use of some of these isolates in biological control of fungal and bacterial pathogens and effect on plant growth enhancement was also examined. Isolation of soil micro— flora were made on soil extract agar and nutrient agar (NA) media, whereas bacteria from ...

The objective was to identify the encystation requirements of Entamoba invadens , strain IP-1. Oxygen was excluded and 0.05cysteine was added to the encystation medium. Growth and encystment both require co2 but at different concentrations. For this strain of amoeba at 23c , 30co2 was optimum for growth; while this amount of co2 inhibited encystation. Maximum encystation took place with 1to 10co2 . The optimum encystation temperature (23c) , was less than that used for the op ...

Evaluation of several transducers has been carried out for direct measurement of number of steps and to step interval in longterm kinmatic studies. The component of a system for reproducibly quantifying the physical disabilities occasioned by inflammatory joint disease and observing variations in performance of physically handicapped as a result of modification to prosthetic orthotic prescription is evaluated in this thesis. The thesis describes principally the anatomy of rel ...
