抄録

Variability in virulence, and some important physiological characters of 6 Indian isolates of Xanthomonas oryzae (Uyeda and Ishiyama) Dowson, the incitant of bacterial blight of rice and their sensitivity to antibiotics in vitro were investigated.<BR>Morphologically, all the isolates were alike. However, with regard to cultural and physiological characters and antibiotic sensitivity, they could be divided into two groups. The first group comprised of 4 isolates, which were slower in growth in culture media with optimum temperature between 25-30°C and thermal death point between 51-52°C, liquefied gelatin slowly, hydrolysed starch partially or not at all, gave alkaline reaction in litmus milk, did not produce hydrogen sulphide and were highly sensitive to all the 5 antibiotics tested, including penicillin. These isolates belonged to the highly virulent group. The other group comprised of 2 isolates, which grew faster on culture media with optimum temperature between 25-35°C and the thermal death point between 52-54°C, liquefied gelatin rapidly, hydrolysed starch completely, gave acid reaction in litmus milk, produced hydrogen sulphide and were insensitive to penicillin and comparatively less sensitive to the other 4 antibiotics. These isolates were comparatively less virulent than the isolates of the first group.
