a comparative study was conducted to find a reliable and simple method for evaluation of resistance of sugar beet genotypes to rhizoctonia root and crown rot. for this, 12 sugar beet genotypes were used in greenhouse, field and in vitro experiments. the field experiment was performed in micro plots (1×1×2 meter) using randomized complete block design with 4 replications. prior to planting, the ...

sheath blight disease, caused by rhizoctonia solani ag-1 ia, is one of the most serious fungal diseases of rice, worldwide. rice resistance is a relative phenomenon and disease response varied (due to complex quantitative inheritance and high environmental diversity), so an accurate disease assessment would be difficult. to detect a reliable reaction of rice in a high level of disease developme...

The definitive diagnosis of spontaneous bacterial peritonitis is made by a positive ascitic fluid culture. Causative organisms cannot be isolated in up to 65% of patients with well-defined spontaneous bacterial peritonitis, probably due to inadequate ascites culture techniques. We prospectively compared two ascites culture methods: conventional (on chocolate agar and thioglycolate broth) and mo...
