Background: In consideration for the increasing widespread use of genetically modified (GM) crops, one of the important issues for assessment is the effect of GM crops on soil microbial communities Objectives: In this study, T2 chitinase-transgenic cotton (line #57) and its non-transgenic line were investigated for bacterial and fungal dynamics...

Side-room examination of fresh samples of urine was compared with the results of surface viable bacterial counts. Examination of centrifuged deposits of urine for bacterial content was shown to compare very well with subsequent culture results. 87% of infected urines were detected, and only 6% of noninfected urines were wrongly identified. Evaluation of the uncentrifuged samples was less easy. ...

In recent years, there has been an increasing interest in using food additives from natural sources to improve taste and also extend the shelf-life of semi-preserved foodstuffs. The aim of this study was to examine the chemical and microbiological changes promoted by a local marinating process in rainbow trout fillets during chilled storage. Fish fillets were immersed in marinades and stored at...

The rise in antimicrobial resistance has become a serious global health problem. Restrictive use of antibiotics seems the only option to temper this accession since research in new antibiotics has halted. Antimicrobial stewardship programmes rely on quick access to susceptibility data. This study evaluated the concept of bacterial cell count monitoring as a fast method to determine susceptibili...

BACKGROUND Procalcitonin has been advocated as a marker of bacterial infection. OBJECTIVE To evaluate diagnostic markers of infection in critically ill children, comparing procalcitonin with C reactive protein and leucocyte count in a paediatric intensive care unit (PICU). METHODS Procalcitonin, C reactive protein, and leucocyte count were measured in 175 children, median age 16 months, on ...

OBJECTIVE To determine the diagnostic value of serum white blood cell (WBC) count, fever (>38˚C) and WBC rise (>10%) for bacterial meningitis in patients with severe traumatic brain injury (TBI). METHOD This cross-sectional study was conducted in Shahid Rajaei hospital affiliated with Shiraz University of Medical Sciences during a 1-year period from 2013 to 2014. We included consecutively all...

BACKGROUND Since delayed diagnosis and treatment of bacterial meningitis worsens patient prognosis, clinicians have a low threshold to perform a lumbar puncture or to start empiric antibiotic treatment in patients suspected of having meningitis. OBJECTIVE To develop a decision rule, including cerebrospinal fluid (CSF) indices and clinical characteristics, to determine whether empiric antibiot...

Eighty samples of bronchoalveolar lavage fluid (BALF) were obtained from the total of 48 patients (22 females and 26 males) and analyzed. Eighteen of those patients were organ transplant recipients. The relationship between polymorphonuclear leukocyte (PMN) count in direct sample and semi quantitative Gram-positive and Gram-negative bacterial content were analyzed in BALF samples. PMN count in ...

BACKGROUND:Mastitis is the most economically importantdisease in dairy industry worldwide. Bulk tank milk (BTM)analysis has been suggested for monitoring the udder healthstatus at herd level. OBJECTIVES: A cross-sectional study wasconducted to evaluate udder health status in 15 Holstein dairyfarms located in Qom province. METHODS: Bulk tank somaticcell count (BTMSCC) was analyzed using opto-flu...

Twenty-seven clinical and laboratory data and the subsequent clinical course of 93 consecutive adult patients who underwent orthotopic liver transplantation for various chronic advanced liver diseases were analyzed retrospectively to assess the risk factors of early major bacterial infection and death after the procedure. Forty-one patients (44%) had early major bacterial infection during hospi...
