Strains of Fusarium produced high levels of T-2 toxin when cultured on certain media absorbed into vermiculite. Modified Gregory medium was nutritionally complex (2% soya meal, 0.5% corn steep liquor, 10% glucose) and, when inoculated with the appropriate fungal strain, yielded maximum T-2 toxin within 24 days of incubation at 19 degrees C. On Vogel synthetic medium N (H. J. Vogel, Microb. Gen...

Experimental infection of the mouse can be used for the determination of virulence of cultures of mammalian tubercle bacilli. The relative virulence of such cultures for the mouse is approximately the same as for the guinea pig. Cultures of virulent and avirulent variants of mammalian tubercle bacilli grown in the depth of Tween 80-albumin liquid medium, on the surface of solid agar modificatio...

On an evolutionary time scale, liquid ventilation is not new. Land-dwelling vertebrates derived from fish 350 million years ago, and fish continue to breathe through a liquid medium. However, the ability to sustain mammalian respiration artificially by a liquid ventilation technique is generally accredited to work in the early 1960s, where mice were kept alive breathing hyperbaric salt solution...

mycoplasmosis is one of the most important diseases in the poultry industry. its causative agent, mycoplasma has various species, which two of them, mycoplasma gallisepticum (mg) and mycoplasma synoviae (ms) are the most important species. due to the enormous losses in the production farms of industrial poultry, achieving a rapid, accurate and definite diagnosis of mycoplasma is of great import...

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...

stachys lavandulifolia vahl is an herbaceous wild plant native to iran which is traditionally used in iranian folk medicine as a mild sedative tea for reducing anxiety and for treatment of gastrointestinal disorders. our previous study on ethyl acetate extract of s. lavandulifolia proved anti-anxiolytic activity and so the present study was designed to determine chemical components of this biol...
