Comparison of natural plant and callus extracts of Solanum trilobatum L. was studied against two bacteria and fungi, for their antimicrobial activity using cup diffusion method. Various solvents such as chloroform, petroleum ether and ethanol were used. The leaf and stem segments of the plant were culturedon Murashige and S koog basal medium supplemented with various growth regulators. Maximum ...

The majority of species in the large genus Solanum (ca. 1500 species) have five-merous, radially symmetrical flowers with equal stamens. However, some Solanum species and groups are characterized by four-merous and/or zygomorphic flowers, unequal stamens and enantiostyly (styles deflected to one side of the flower). Previous workers have used flower and seed coat morphology in these unusual Sol...

Michaels, Ruth (Columbia University, New York, N.Y.), and W. A. Corpe. Cyanide formation by Chromobacterium violaceum. J. Bacteriol. 89:106-112. 1965.-The formation of cyanide by a Chromobacterium violaceum strain was studied with growing cultures and with nonproliferating cells grown in complex and chemically defined media. Most of the cyanide was produced during the log-phase growth of the or...

BACKGROUND Chromobacterium violaceum is a proteobacterium found in soil and water in tropical regions. The organism rarely causes infection in humans, yet can cause a severe systemic infection by entering the bloodstream via an open wound. CASE PRESENTATION We recently identified a case of severe bacteremia caused by Chromobacterium violaceum at the Hospital for Tropical Diseases (HTD) in Ho ...

BACKGROUND The genus Chromobacterium consists of 7 recognized species. Among those, only C. violaceum, commonly found in the soil and water of tropical and subtropical regions, has been shown to cause human infection. Although human infection is rare, C. violaceum can cause life-threatening sepsis, with metastatic abscesses, most frequently infecting those who are young and healthy. CASE PRES...

Out of 53 consecutive cases of tinea o scalp that have been seen at the Cl1 a School of Tropical Medicine during the as three years 20 have been found to be caused by Trichophyton violaceum; the remainder wer caused by Microsporon audouini with the exception of two cases of favus. These 20 cases of T. violaceum infection included five Europeans, twelve Mohammed and three Marwaris. No case was o...

Fungi often mate as haploids, and sex chromosomes (i.e., mating-type chromosomes) that are dimorphic for their size or overall DNA content have never been reported in this kingdom. Using electrophoretic techniques for karyotype analysis, a highly dimorphic chromosome pair that determines mating compatibility is shown to occur in populations of the fungus Microbotryum violaceum. This substantiat...
