because of inappropriate use of antibiotics and prevalence of resistant bacteria, there is urgentneed for antibacterial drugs that have fewer side effects than antibiotics. myrtus communis is amedicinal plant which had many uses in traditional medicine. in this study, ethanol leave extractof this plant is tested on acinetobacter baumannii. in the case of antimicrobial evaluation ofplants, one o...

this study was conducted to compare susceptibility of six different strains of male broilers to ascites syndrome. in this experiment, 612 one-day-old male broiler chicks from five international hybrids (e.g, arbor acres, cobb 500, hubbard, lohmann, and ross 508) and an iranian hybrid (arian) were used. growth performance, ascites mortality ratio, the ratio of right ventricle to total ventricles...

background and objectives: tannins are toxic polyphenols that either bind and precipitate or condense proteins. the high tannin content of some plants is the preliminary limitation of using them as a ruminant feed. so, the aim of this study was the isolation and characterization of tannic acid degrading bacterial strains from goat feces before and after feeding on pis- tachio-soft hulls as tann...

in the present study, 110 fungal strains of persian type culture collection (ptcc) including some selected strains isolated in various screening projects were tested for their potentiality to produce lovastatin, a competitive inhibitor of 3-hydroxy-3-methylglutaryl-coa reductase (hmg-coa reduc-tase), the rate-limiting enzyme of cholesterol biosynthesis. the fungal strains were cultivated in a t...

ELUCIDATING THE EVOLUTIONARY ORIGINS OF COLLECTIVE ANIMAL BEHAVIOR

conclusions our study emphasized the increasing role of esbl genes, especially blactx-m15 in epec isolates. results of 42 epec, eight isolates carried the blactx-m1. none of the isolates carried blactx-m2 and blactx-m9. the blactx-m15 variant was identified in all of blactx-m1-positive isolates. furthermore, blashv and blatem genes were detected in 40.5% (n = 17) and 19% (n = 8) of all epec iso...

background: as regards multilocus sequence typing (mlst) method directly analyze the polymorphism within dna sequences; we performed the first nationwide study on the genotypic relationships of candida albicans strains obtained from oropharynx and bronchoalveolar lavage (bal) samples from immunocompromised patients. methods: fourteen epidemiologically unrelated clinical strains of c. albicans w...

Temporally precise inhibition of genetically defined cell populations in intact nervous systems has been enabled by the microbial halorhodopsin NpHR, a fast, light-activated chloride pump. Here, we report the generation of new mouse strains that express eNpHR2-EYFP fusion proteins after Cre- and/or Flp-mediated recombination to silence neural activity in vivo. In these mouse strains, Cre/Flp re...
