AIMS To investigate the suitability of Hugh and Leifson's medium (HLM) as the basis of a simple screening test to differentiate between contaminants and Arcobacter spp. during their isolation from foodstuffs. METHODS AND RESULTS Characterized Arcobacter spp. were obtained from recognized culture collections. Wild-type isolates of Arcobacter spp. and(More)
In order to determine the most effective protocol for the isolation of Arcobacter spp. from retail packs of beef, three published methods (A, B, and C) were selected. In addition, a modified version of method B was studied (method D). The ability of the four methods to isolate Arcobacter from standardized beef samples (n = 80) was compared with presumptive(More)
A field experiment was established in which an amendment of poultry manure and sawdust (200 t/ha) was incorporated into some plots but not others and then a permanent pasture or a sequence of biomass-producing crops was grown with and without tillage, with all biomass being returned to the soil. After 4 years, soil C levels were highest in amended plots,(More)
Genetic variation among 29 isolates of Fusarium oxysporum f.sp. zingiberi (Foz) collected from diseased ginger rhizome in production regions throughout Queensland was analysed using DNA amplification fingerprinting (DAF). Eight isolates of other Fusarium species and/or formae speciales were included for comparative analysis. Within the Foz isolates, three(More)
In February 1986 Cyclone Winilred, with wind gusts 01 up to 176 km/h and accompanied Ьу torrential rain, devastated coastal areas 01 north Queensland. In late March 1986, а severe Iruit and stem rot 01 papaw (Carica рарауа L.) was observed to Ье devastating ап Innislail plantation (Iat. 17031', long. 146001 '). Isolations were made Irom affected roots,(More)
TRFLP (terminal restriction fragment length polymorphism) was used to assess whether management practices that improved disease suppression and/or yield in a 4-year ginger field trial were related to changes in soil microbial community structure. Bacterial and fungal community profiles were defined by presence and abundance of terminal restriction fragments(More)
