the in vitro antimicrobial activity of the essential oil isolated from the aerial parts of cymbopogon olivieri (boiss.) bor, an aromatic grass of iran was tested against three gram-negative and four gram-positive bacteria and also three fungi. the results of the bioassays showed that the oil has a remarkable antimicrobial activity. bacillus subtilis and candida albicans were more sensitive to t...

background: campylobacter infections may lead to serious conditions, including septicemia or other invasive forms of the disease, which require rapid and accurate laboratory diagnosis and subsequently appropriate antimicrobial therapy. the aim of this study was to compare the species distribution and antimicrobial susceptibility pattern of campylobacter spp. strains isolated from patients and f...

introduction: selected probiotic lactobacilli have inhibitory effect and therefore may be use as biological preservative, so, the aim of this study was to present some data on isolation, growth, antimicrobial activity, effect of ph, heat, and sensitivity to proteolytic enzymes of lactobacillus. material and methods: isolation of lactic acid bacteria from sausage was done by using 1g of samples ...

Ornithobacterium rhinotracheale (ORT) is a bacterium associated with respiratory disease, growth retardation, decreased egg production and mortality in chickens and turkeys. The objective of this study was isolation, identification and evaluation of antimicrobial susceptibility of ORT bacterium in slaughtered broilers chicken flocks based on cultural and molecular tests in Khuzestan pr...

The objective of this study was to evaluate the prevalence of antimicrobial resistance in Helicobacter pylori isolated from the antrum and corpus of dyspeptic patients in Khon Kaen, Thailand, and to compare the antimicrobial susceptibility patterns of H. pylori isolated from the antrum and corpus in individual patients. Antimicrobial susceptibility was determined by disk diffusion, studying sus...

AIM For frequency Escherichia (E.) coli is the agent of urinary tract infections (UTIs). The objective of the present study was to evaluate in vitro activity of several antimicrobial agents to guide empirical treatment of uncomplicated UTIs. In vitro antimicrobial susceptibility of 429 E. coli strains, isolated in urine specimens from community-acquired uncomplicated UTIs in outpatients, was st...

background and objectives: klebsiella pneumoniae ( k. pneumoniae ) is an opportunistic microorganism. this study aimed to investigate the presence of mag a gene and antimicrobial susceptibility in k. pneumoniae . materials and methods: 195 clinical specimens were collected from hospitals of shahrekord, iran. bacterial culture, biochemical diagnostic standard test, determination of antibiotic se...

The objective of this research was to isolate and to verify the sensitivity to antimicrobial agents of strains of Salmonella sp. isolated from poultry products in the state of Ceara, Brazil. A total number of 114 samples was collected from 63 broiler carcasses derived from two processing plants and two supermarkets, and 51 excreta samples were collected in broiler farms located in the state of ...

Determining the susceptibility of pathogens to antibacterial substances is one key steps in bacteriological diagnostics that affects success both therapeutic therapy and appropriate selection cosmetic products. Antibiotic chemotherapeutic sensitivity tests determine ability an antimicrobial agent inhibit growth a microorganism vitro.

Effect of different solvents; dimethyl-sulfoxide (DMSO), dimethyl formamide (DMF), methanol, tween 80 and acetone on morphology, cytology and reproduction of Aspergillus flavus, A. parasiticus, A. fumigatus and A. niger was assayed for standardization of a suitable organic solvent for test/antimicrobial compound in antimicrobial assays. Comparison of antimicrobial sensitivity methods was also m...
