Restriction fragment length polymorphism analysis of numerous Frankia strains, using a nifDH probe, separated the strains into three distinct groups based on hybridization patterns. The groups identified in this study were well correlated with host specificity groups identified in earlier cross-inoculation studies.

The effect of potash biofertilizer and chemical fertilizer was studied on quantitative and qualitative traits of periwinkle in a factorial experiment based on a Randomized Complete Design with three replications, 48 experimental units, and two factors: (1) different methods of potash bio-fertilizer application at four levels of control (B0), seed inoculation (B1), root inoculation (B2) and seed...

Nodulation ability of 15 Rhizobium strains isolated from root and stem nodules of tropical Aeschynomene species was studied on 20 different Aeschynomene species and four other legumes-Arachis hypogaea, Stylosanthes guianensis, Macroptilium atropurpureum, and Sesbania rostrata. The results of this investigation showed that Aeschynomene species could be divided into three groups according to the ...

the efficacy of that procedure in the way which had been commended, for such purposes, in my evidence to the Plague Commission of 1898-99, and in which I had been testing curative treatments in India. The experiment on that occasion was not completed by them, and although the preliminary statement which they made oil the results was favourable to the therapy, they did not persevere with the stu...

In 2018, up to 4 million m3 Norway spruce was killed by the bark beetle Ips typographus in Sweden. The event unique for Sweden, terms of both affected volume and fact that it triggered severe drought stress, not ample availability relatively defenseless storm-felled trees. outbreak continued 2019 2020, each year with twice as many trees 2018. aim this study quantify seasonal variation potential...

The macaque model of chlamydial pelvic inflammatory disease (PID) demonstrates individual variability in the time of onset of intrapelvic adhesions. Some animals develop adhesions rapidly, within 2 weeks after a single tubal inoculation with Chlamydia trachomatis, while in others, adhesions are not observed until 2 weeks after a second tubal inoculation. To test whether this variability correla...

The initial interaction between bacteria and the renal pelvic epithelium may determine whether intrarenal infection occurs. A model of retrograde pyelonephritis was employed to study these events by electron microscopy. Female rats received an intravesicular inoculation of a 0.5-ml suspension of Proteus mirabilis containing 10(8) organisms. At intervals after inoculation, the kidneys were fixed...
