The aims of this study were to assess the common bacterial microorganisms causing UTI and their antimicrobial resistance patterns in Bandar Abbas (Southern Iran) during a four-year period. In this retrospective study, samples with a colony count of ≥105 CFU/mL bacteria were considered positive; for these samples, the bacteria were identified, and the profile of antibiotic susceptibility was characterized. From the 19223 samples analyzed, 1513 (7.87%) were positive for bacterial infection. UTI was more frequent in male (54.9%). E. coli was reported the most common etiological agent of UTI (65.2%), followed by Klebsiella spp. (26%), Pseudomonas aeruginosa (3.6%), and Staphylococcus coagulase positive (3.7%). Results of antimicrobial susceptibility analysis for E. coli to commonly used antibiotics are as follows: Amikacin (79.7%), Ofloxacin (78.3%), Gentamicin (71.6%), Ceftriaxone (41.8), Cefotaxime (41.4%), and Cefixime (27.8%). Empirical antibiotic selection should be based on awareness of the local prevalence of bacterial organisms and antibiotic sensitivities rather than on universal or even national guidelines. In this study, Amikacin and Gentamicin were shown to be the most appropriate antibiotics for empiric therapy of pyelonephritis, but empirical therapy should only be done by specialist physicians in cases where it is necessary while considering sex and age of children.
R. 2003. Astragalus sect. Astragalus (Fabaceae) in Iran, complementary notes with a key to the species. -Nord. J. Bot. 22: 177-181. Copenhagen. ISSN 0107-055X. Astragalus zarreianus. is described and illustrated from Iran. It belongs to section Astragalus. This new species confined to western part of Iran (Prov. Illam) from only one location.A key to the species of the section known from Iran is prepared. Differences between the section and the closely related sections are discussed. On the basis of some important trends, an informal grouping is undertaken for yellow flower Astragali. Moreover, A. pseudo-orthocarpus is considered as a valid species in this treatment and differences with its closest relatives are described.
In this paper a key, descriptions and new results are provided for Trigonella sect. Ellipticae occuring within the area covered by the flora of Iran. Trigonella sect. Ellipticae comprises perennial herbs, becoming woody at the base, with standard as long as keel and pods glabrous or rarely covered with gray dense and appressed hairs. Trigonella lasiocarpa Ranjbar & Hajmoradi, T. binaloudensis Ranjbar & Karamian, T. stipitata Ranjbar & Joharchi and T. torbatejamensis Ranjbar are described and illustrated as new species based on habit and pollen morphology. The relationships between the new species and their closest relatives are discussed. The pollen morphology of 26 specimens belonging to 11 species was studied with light and electron microscopy and discussed in the context of existing hypotheses on the systematic relationships within T. sect. Ellipticae. In addition, T. heratensis Rech. f. and T. adscendens Aphan. & Gontsch. are reported as new records for Iran.
A survey on chromosome counts of different sections belonging to the genus Scutellaria L. (Lamiaceae) throughout the world is presented and the relationships between chromosome data of its sections and their biogeography are also discussed here. In addition, meiotic chromosome numbers of 20 populations belonging to eight species growing in Iran, namely S. tomentosa (2n = 2x = 22), S. theobromina (2n = 2x = 22), S. araxensis (2n = 2x = 22), S. platystegia (2n = 2x = 22), S. nepetifolia (2n = 2x = 22), S. farsistanica (2n = 2x = 22), S. persica (2n = 2x = 22) and S. pinnatifida (2n = 2x = 22) were determined. With exception of S. pinatifida, all chromosome counts are reported for the first time, and are consistent with proposed base number of x = 11.
Astragalus rahiminejadii , a new species endemic to Iran, is described and illustrated. This species, which belongs to section Astragalus , is confined to the western part of Iran (Prov. Kermanshah) and is known only from a single population. Seed testa morphology as viewed under the scanning electron microscope is discussed and photomicrographs are provided. In addition, the geographical distribution and ecology of the species belonging to this section are discussed.
