Mycobacterium avium subsp. paratuberculosis and Mycobacterium avium subsp. avium are antigenically and genetically similar organisms; however, they differ in their virulence for cattle. M. avium subsp. paratuberculosis causes a chronic intestinal infection leading to a chronic wasting disease termed paratuberculosis or Johne's disease, whereas M. avium subsp. avium causes only a transient infec...
The small subunit ribosomal RNA (SSU rRNA) encoding genes from reference strains of Aeromonas salmonicida subsp. smithia and Haemophilus piscium were amplified by polymerase chain reaction and cloned into Escherichia coli cells. Almost the entire SSU rRNA gene sequence (1505 nucleotides) from both organisms was determined. These DNA sequences were compared with those previously described from A...
Several aspects of genotype-environment interaction may act to modulate natural selection in populations that encounter variable environments. In this study the norms of reaction (phenotypic responses) of 20 cloned genotypes from two natural populations of the annual plant Polygonum persicaria were determined over a broad range of controlled light environments (8%-100% full sun). These data rev...
In this study cellular proteins of in vitro grown horseradish (Armoracia lapathifolia Gilib.) tissues of different morphologies, leaves (L), teratoma (TM) and tumor (TN), were separated by one-dimensional (1-DE) and two-dimensional polyacrylamide gel electrophoresis (2-DE) in order to reveal developmentally specific proteins. Moreover, proteins were subjected to analyses by lectin assays to rev...
سرده campanula دارای حدود 43 گونه در ایران می باشد؛ از این تعداد 12 گونه و 1 زیرگونه در شمال کشور رویش دارند. در مطالعه حاضر به منظور تمایز گونه های شمال ایران، از صفات ریخت شناسی، صفات تشریحی برگ و صفات ریزریخت شناسی بذر استفاده شده است. به منظور تعیین روابط بین گونه ها از آنالیز عددی به روش euclidian/upgma با نرم افزار ntsys-pc (ver. 2.1) استفاده شد؛ ماتریس اطلاعات از 62 صفت ریخت شناسی، تشریح...
Campylobacter fetus currently comprises three recognized subspecies, which display distinct host association. Campylobacter fetus subsp. fetus and C fetus subsp. venerealis are both associated with endothermic mammals, primarily ruminants, whereas C fetus subsp. testudinum is primarily associated with ectothermic reptiles. Both C. fetus subsp. testudinum and C. fetus subsp. fetus have been asso...
