Samples from the kidney of 100 diseased fish with signs of haemorrhagic septicemia and 50 samples from outlet water of fish farms were taken aseptically and cultured. In the laboratory, 75 colonies of gram-negative bacteria were biochemically diagnosed as motile aeromonads in our Bacteriology Laboratory Unit using API 20E rapid identification system. The genotype identification using specific p...

Random regression models (RRM) have become common for the analysis of longitudinal data or repeated records on individual over time. The goal of this paper was to explore the use of random regression models with orthogonal / Legendre polynomials (RRL) to analyze new repeated measures called clutch size (CS) as a meristic trait for Iranian native fowl. Legendre polynomial functions of increasing...

objective: flowering time (ft) in cereals controlled by genes that had a main factor on plant development. methods: genetic and phenotypic diversity of four flowering time genes (ft2, ft3, ft4, ppd-h1) in 19 genotypes of cultivated and wild barley was evaluated and a total of 107 alleles were amplified. genotypes based on days to flowering time and molecular data were grouped into early, middle...

One of the sources of evidence for the somatic mutation hypothesis of cancer is in studies of cor relation between mutagenic and carcinogenic ca pacities of physical and chemical agents. Tests in this laboratory have suggested a positive correla tion within the limits of three mustard compounds. Both the nitrogen mustard, methylbis (2-chloroethyl)amine hydrochloride, and sulfur mustard, bis(2-c...
