Isolates isolated from maize and 3 isolates from rice, wheat, adzuki bean in ten provinces were identified as Curvularia lunata. Based on the culture characters, such as color of colony, aerial myeelia, the number of conidia, there were some difference among 43 isolates. Meanwhile, five types of conidium were compared in culture characters and virulence. In each single conidia culture there were different morphic conidia also and no difference in virulence was found among five single-conidium cultures.

Furthermore, the results of the antibiotics sensitivity test of 38 isolates to 24 kinds antibiotics show that all isolates have presented antibiotic resistance disparately as well as multi-resistance. All isolates are sensitive to Cephalosporins antibiotics and Aminoglycosides antibiotics such as Amikacin, Cefazolin, Cefradine, Cefoperazone, and Ceftriaxone. Thirty-eight isolates are extremely resistant to Penicillins antibiotics, Lincomycins antibiotics, Tetracyclines antibiotics and Macrolides antibiotics such as Midecamycine, Lincomycin, Carbenicillin, Tetracycline, Amoxicillin and so on. Antibiotics sensitivity test provides guidance for antibiotic application and scientific foundation from poultry farms.

Reaction of 24 Einkorn accessions to mixed inoculum of powdery mildew and stripe rust,and two T.urartu accessions UR204,UR206 and a T.monococcum accession MO205 were used for reaction to a set of 15 differential Blumeria graminis tritici isolates and 21 differential Puccinia striiformis isolates,respectively.Among them,UR206 was resistant to all 15 isolates,UR204 was resistant to 14 isolates except E11,and MO205 showed different resistant types.The results indicated that most likely UR206 and UR204 carried new powdery mildew resistance genes that were different from 18 known Pm genes and MO205 carried new stripe rust gene that were different from 24 known Yr genes.

Methods Two arrays of isolates were used to evaluate the reliability of ChromID ESBL. One array contained 285 clinical isolates in which the ESBLs-producing feature was screened by confirmatory tests recommended by Clinical and laboratory Standards Institute. The other array contained 28 enterobacterial isolates with their ESBLs gene and producing enzyme feature being confirmed previously.
