Background and Objective: Salmonellosis is an important infectious zoonotic disease that makes it even more significant to identify and control the causative strains. Molecular methods, especially polymerase chain reaction (PCR), for virulence genes can help to quickly and accurately identify Salmonella strains. Accordingly, the purpose of this study was molecular identification based on sivH, ...

alfalfa (medicago sativa) is among a few of the most important forage crops for the growth of which hamedan province benefits from a suitable climate. alfalfa bacterial wilt disease induced by clavibacter michiganensis subsp. insidiosus cause substantial economic crop losses. this disease has not been so far investigated extensively in hamedan province. in the course of this survey affected pla...

Background: Enterococci have emerged as a major cause of nosocomial infections and within this group, Enterococcus faecalis and Enterococcus faecium cause the majority of human and livestock enterococcal infections. In this article, we tried to determine antibiotics and metals resistance patterns of E. faecalis and E. faecium strains. Methods: One hundred sixty different strains of E. faecalis...

background : due to the importance of the metal zinc as an essential biological element with known toxic properties, and considering the widespread secondary infections caused by pseudomonas aeruginosa strains with resistance to antibiotics and disinfectants, the present study aimed at exploring the antimicrobial properties of the metal zinc in both clinical and environmental multiple drug resi...

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...

conclusions these results indicated that eaec strains isolated from iranian children with diarrhea were heterogeneous and showed high resistance rates against commonly used antibiotics, which was similar to that reported in studies performed in other countries. results significant percentage of local eaec strains carried the virulence plasmid genes and formed biofilms. in addition, these strain...

during 2007-2008, 58 strains of p. syringae pv. syringae (pss) were isolated from various prunus species and other hosts such as sugar beet, pear, quince, oat, millet, wheat, barley, and rice in fars, isfahan, kohgiloye and boyer ahmad, chahar mahal-o-bakhtiari provinces of iran. the strains were tested for pathogenicity, the presence of the syrb gene and box pcr (box a1r primer). all teste...

in determination of particular types of coagulate positive staphylococci (staphylococcus aurous) causing different diseases, especially hospital sepsis and food poisonings; 186 strains of coagulase positive staphylococci from different provinces in iran were phage typed. because of various sources of the strains, the results had some differences, as 15.8 percent or 15 strains separated from chi...
