BACKGROUND PCR is a molecular technique for herpes simplex virus (HSV) detection that can cause life-threatening infections such as encephalitis and keratitis. However, the main issues, false-negative results causing by PCR inhibitors, of this technique that reduce PCR efficiency. To overcome this problem, a competitive internal amplification control (IAC) was constructed for conventional PCR u...

conclusions our findings revealed that the zfn technology could be employed to overcome ampicillin resistance by the targeted disruption of the ampicillin resistance gene, which leads to inactivation of β-lactam synthesis. therefore, zfn technology could be engaged to decrease the antibiotic resistance issue with the construction of a zfn archive against different args. to tackle the resistance...

BACKGROUND The assays currently available for the detection of specific anti-Toxoplasma antibodies may vary in their abilities to detect serum immunoglobulins, due to the Lack of a purified standardized antigen. The aim of this study was evaluation the recombinant Toxoplasma gondii SAG1 antigen for the serodiagnosis of acute and chronic toxoplasmosis. METHODS This study describes an ELISA usi...

Brucellosis is a debilitative disease that imposes costs on both economy and society. It is shown that although the vaccine can prevent abortion, it does not provide complete protection against infection. In Iran, Brucella melitensis is a common causative agent for brucellosis and BP26 protein of this bacterium having a good antigenesity and an important vaccine candidate. In this study B. meli...

Rhodococcus FMF is a gram-positive bacterium isolated for the first time from soil samples of Tabriz refinery in Iran. This microorganism is able to catabolize dibenzothiophene to 2-hydroxybiphenyl and inorganic sulfur without the destruction of carbon-carbon bonds. Three structural genes, dszA, dszB, and dszC have been characterized and shown to be responsible for this phenotype. In this work,...
