Bacillus subtilis spo0K mutants are blocked at the first step in sporulation. The spo0K strain was found to contain two mutations: one was linked to the trpS locus, and the other was elsewhere on the chromosome. The mutation linked to... more
Inhibitory effect of REP3123 on toxin and spore formation in
Biomonitoring programs to access the ecological integrity of freshwaters tend to rely exclusively on structural parameters. Here we evaluated stream ecological integrity using (a) benthic macroinvertebrate derived metrics and a biotic... more
Media for yeast identification tests were incorporated into the wells of a microtitre tray. The tests included fermentation and assimilation of carbohydrates, assimilation of nitrogen compounds, growth in vitamin-free medium, resistance... more
Ulocladium atrum (strain 385) consistently reduced Botrytis cinerea sporulation on necrotic fragments of strawberry leaves. On these tissues, two strains of U. atrum (isolates 18558 and 18559) showed lower antagonistic activities than the... more
Coprological examinations of eight Ruppell’s agamas Agama rueppelli (Vaillant) revealed the presence of a coccidium of the genus Isospora Schneider, 1881 that represents a previously undescribed species. Oöcysts of Isospora farahi n. sp.... more
Visceral leishmaniasis is a zoonosis whose primary vector in Brazil is the sandfly Lutzomyia longipalpis Lutz & Neiva. Presently, efforts to control the vector have not been effective in reducing the prevalence of disease. A possible... more
Histidine kinases are sophisticated molecular sensors that are used by bacteria to detect and respond to a multitude of environ- mental signals. KinA is the major histidine kinase required for initiation of sporulation upon nutrient... more
