Coccidioides immitis undergoes a completely different type of growth in vivo from that in vitro. The parasitic form, or spherule, appears in animal tissue as a non-budding, spherical structure 20 to 80 ,u in diameter with a thick, refractile, double wall, and is filled witlh numerous small endospores 2 to 5 ,u in diameter. The saprophytic form appears in laboratory media as mycelium with branch...

abstract the aim of this study was the identify cyanobacterial flora of rice–fields in dargaz, to interaction between cyanobacteria by culturing in solid medium bg-110 in laboratory was investigated. nostoc piscinale and nostoc spongiaeforme were identified as strongest and weakness species, respectively, regarding secondary metabolits producing (allelochemicals).the algal pairs were classified...

Environments contaminated with heavy metals negatively impact the living organisms. Ectomycorrhizal fungi have shown important role in these impacted sites. Thus, this study aimed to evaluate the copper-resistance of ectomycorrhizal fungi isolates Pisolithus microcarpus - UFSC-Pt116; Pisolithus sp. - UFSC-PT24, Suillus sp. - UFSM RA 2.8 and Scleroderma sp. - UFSC-Sc124 to different copper doses...

This paper presents a numerical investigation for laminar forced convection flow of a radiating gas in a rectangular duct with a solid element that makes a backward facing step. The fluid is treated as a gray, absorbing, emitting and scattering medium. The governing differential equations consisting the continuity, momentum and energy are solved numerically by the computational fluid dynamics t...

For infection of animals control-cultures from the sensitivity tests were used. These were always the first subcultures on solid egg medium about four weeks old. The cultures were resistant to isoniazid, but susceptible to streptomycin, para-aminosalicylic acid and conteben. They were weighed wet, suspended in normal saline and injected subcutaneously in the right inguinal region. The guinea pi...

The results of disk diffusion and plate dilution susceptibility testing of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis on media gelled with agar-agar or with a synthetic hydrogel were compared. Synthetic hydrogel can be combined with a totally defined synthetic amino acid medium to yield a reproducible, totally defined, synthetic solid medium without t...

Mutants of Escherichia coli K-12 unable to excise pyrimidine dimers from their deoxyribonucleic acid (DNA) because of a uvr mutation show a higher survival when plated on a minimal salts medium after exposure to ultraviolet radiation than when plated on a complex medium such as nutrient agar containing yeast extract. This response has been called minimal medium recovery (MMR). Recovery of uvr m...

We determined the effect tunicamycin (TM), an inhibitor of protein glycosylation, had on cells in vitro that were derived from solid and ascites variants of a chemically induced rat hepatoma. Using flow microfluorometry (FMF), labelling index (LI), and population-doubling time assays, we monitored the progression of cells through the cell cycle after treatment with TM. Cells in monolayer cultur...
