Global-scale data on the Oligocene to Recent planktic foraminifers and coccoliths from the tropical Pacific and Atlantic Oceans are employed for quantitative testing of alternative models (Red Queen and Stationary Hypotheses) of the relationship between speciation rates, extinction rates, taxonomic diversity, abiotic events, and history of the paleosystem. The results demonstrate that although ...
Pigmentation of ascospore-derived isolates from seven different natural specimens of Cordyceps militaris EFCC C-5888, EFCC C-7159, EFCC C-7833, EFCC C-7991, EFCC C-8021, EFCC C-8023 and EFCC C-8179 was observed on the plates of Sabouraud Dextrose agar plus Yeast Extract at 25℃ under continuous illumination (500 lux). Pigmentation of the wild-type isolates of C. militaris was diverse ranging fro...
The IS1311 polymerase chain reaction-restriction endonuclease analysis was used to detect genetic differences among 38 Mycobacterium avium subsp. paratuberculosis (Map) isolates from cattle, sheep, goats and bison from distinct regions of Spain, India and the United States of America (USA). In Spain, all eight bovine isolates, three out of six caprine isolates and one of ten ovine isolates were...
Background and Objective: To evaluate extended spectrum betalactamase (ESBL) positive strains of Klebsiella pneumonia and Escherichia coli in positive bacterial cultures. Materials and Methods: In this analytical cross-sectional study, between March 2006 and March 2007, 170 bacterial isolates including 133 cases of E. coli and 37cases of K. pneumonia were...
the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
Swine dysentery (SD) is a mucohaemorrhagic colitis of grower/finisher pigs classically resulting from infection by the anaerobic intestinal spirochaete Brachyspira hyodysenteriae. This study aimed to determine whether B. hyodysenteriae isolates from pigs in three healthy German multiplier herds supplying gilts to other farms differed from isolates from nine German production herds with SD. Isol...
abstract: one of the most visited & important spaces in different countries by tourist are urban areas. the old tehran which major part is located in district 12 is historical showcase of the capital, but, its hiidden cultural attraction is not used as it should be. this thesis occasionally engage in studying the efficacy of correct installation of travel guide boards in welfare & easily acc...
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
Wild species of the genus Oryza are excellent gene pools for improvement of agronomic traits of Asian cultivated rice. The blast resistance gene Pi57(t) in the introgression line IL-E1454 derived from Oryza longistaminata was previously mapped on rice chromosome 12. Inoculation with 322 Magnaporthe oryzae isolates collected from 6 countries indicated that Pi57(t) conferred broad spectrum resist...
