a 3 × 2 factorial experiment was conducted to investigate the effect of thymol + carvacrol (0, 100 and 200 mg/kg) on ileal microbial population and jejuna and ileal histomorphology of broilers fed carboxy methyl cellulose (cmc: 0 and 2%) containing diet. each of the 6 dietary treatments was replicated 5 times with 12 chicks each from 0 to 42 days of age. there was no interaction effect of cmc a...

microbial steroid biotransformation have found wide-reaching application for the production of more precious and functionalized compounds due to their high regio-and stereoselectivity. in this study, the possibility of using filamentous fungi aspergillus brasiliensis cells in the biotransformation of progesterone (i), a c-21 steroid hormone was studied for the first time.the fungal strain was i...

pharmaceutical products prepared in pharmacies have the potential of contamination with different microorganisms. this is in part due to the unhygienic environment and also lack of a suitable preservative system. in this study, microbial quality of eucerin-urea ointments prepared at different pharmacies in tehran, at the point of sale and also after two weeks storage at room temperature was exa...

this study assessed the chemical and microbial contents in the water of public swimming pools in akwa ibom state, nigeria. a total of 16 public pools were selected through probability sampling from the 32 pools that existed in the five urban areas of akwa ibom state. water samples were collected from the sampled pools and tested in the laboratory for chemical and microbial contents. results sho...

background acinetobacter has become an important cause of different infections such as wound infection, due to its great ability to survive and spread in hospital settings and to develop resistance against many antibiotics. objectives the aim of this study was to investigate the antibiotic resistance among isolates of acinetobacter from wound infections during a 7-year period, from 2005 to 2011...

objectives : the present study was designed to evaluate the changes in saliva properties and oral microbial flora in patients undergoing fixed orthodontic treatment. materials and methods: two important saliva properties namely the salivary flow rate and ph as well as oral microbial flora were assessed in 30 orthodontic patients before starting fixed orthodontic treatment and after six, 12 and ...

conclusions in conclusion, these results suggested a need for a switch to second line therapy regimens for treatment of infected patients in the iranian population. results helicobacter pylori infection was detected in 22 patients (22.92%). identity of the isolates was confirmed by pcr using glmm primers. chronic gastritis, duodenitis, intestinal metaplasia, dysplasia and cancer were detected a...

Soil microbial biomass plays an important role in nutrient transformation in terrestrial ecosystems. Microbial biomass is also an early indicator of changes in total soil organic carbon. Thus, the main objective of this study was to identify and quantify the present status of soil microbial biomass carbon and nitrogen with various management practices in Himalayan rangeland. To meet the aforeme...

abstract cadmium is one of the heavy metals with a considerable importance for its potential toxic effects on soil microbial activities and composition. although, the toxic effect of cadmium on soil microbial activities is somewhat well-known, but the extent to which cd affects soil biota depends largely on soil properties and conditions, particularly soil organic matter contents. thus, the aim...
