The prevalence and risk factor of hepatitis B and D in Shiraz blood donors

  The estimation of prevalence rate of hepatitis B (HBV) in blood donors and hepatitis D (HDV) infection in HBV carriers is important in estimating the prognosis of hepatitis due to more severe rate of liver disease in HDV/HBV co-infected patients. The aim of the study was to analyze the prevalence of HBV in blood donors and HDV among hepatitis B surface antigen (HBsAg) positive-blood donors in Shiraz, Fars,...

Antimicrobial consumption at a university hospital in Turkey

  Excessive antibiotic use is a challenging topic because of the total annual expenditure and the high resistance against antimicrobials in Turkey. A point-prevalence study was performed to evaluate the daily antibiotic consumption and the cost. Data were collected by infectious diseases consultants on 30 January, 2009 and 28 January 2010. Anatomical therapeutic chemical classification and the defined daily...

The effect of a continuous mercury stress on mercury reducing community of some characterized bacterial strains

  Active resistance to the mercuric ion is widely distributed in environmental microbes and results from the action of mercuric reductase. Five mercury resistant bacteria:Escherichia coli Z1, Escherichia coli Z3, Pseudomonas putida Z2, Serratia marcescensZ4 and Xanthomonas sp. Z5 were isolated and identified from sludge sample. The presence of mercury resistance determinants was...

Prognostic significance of transforming growth factor-beta-1 in chronic hepatitis C virus infection

  Interferon treatment in hepatitis C virus (HCV) infection is expensive and has various adverse effects. Some markers may help in making decision to stop or maintain the treatment. The aim of this study was to evaluate the effectiveness of serum transforming growth factor beta-1 (TGF-β1) in assessing outcome of interferon treatment in patients with HCV infection. Twelve patients with chronic HCV...

Characterization and identification of a Bacillus strain TS02 as bio-control agent of strawberry powdery mildew

  Powdery mildew of strawberry is a major limitation in most fruit production areas in the world. The effects of the Bacillus strain TS02 on bio-controlling powdery mildew of strawberry were tested in the fields. The results indicated that the fermented liquid of TS02 above 3×107 CFU/ml live bacteria concentration could control the disease of strawberry powdery mildew. The best...

Antidiabetic effect of camel milk on alloxan-induced diabetic dogs

  This research was conducted to evaluate the antidiabetic effect of camel milk in alloxan-induced-diabetic dogs. Diabetes was induced by intravenous injection of alloxan monohydrate (65 mg/kg bodyweight). The effects of camel milk on diabetic dogs were investigated by observing changes in the glycometabolic index (fasting blood glucose,intravenous glucose tolerance test (IGTT)) test, the lipometabolic index...

Distribution of Mycobacterium tuberculosis and human immunodeficiency virus infections among contacts of tuberculosis patients

  Contacts of tuberculosis (TB) cases in households or sharing space in hospitals, classrooms, offices, market stalls or other, were evaluated by tuberculin skin test (TST), sputum-smear microscopy or sputum culture method for Mycobacterium tuberculosisand by serology for HIV infections. Of the 633 contacts, 47.4% were TST-positive and 18.2% HIV-infected. Household contacts were 174 and 51.2% of them were...

Isolation of Brucella abortus from the milk of serum positive cows using chiken embryos as amplifier

Brucellosis is generally acquired by the ingestion of raw milk and unpasteurized dairy products. As an infection model, chicken embryos (CE) were used to isolate Brucella abortus from milk cream of eight seropositive cows. One hundred CE, seven to nine day-old, were inoculated and divided into 10 groups of 10 each; eight of them inoculated with milk cream from seropositive cows, one served as a positive...

Genome shuffling of Megasphaera elsdenii for improving acid-tolerance and propionate production

In this study, genome shuffling was conducted to improve the propionate production and acid-tolerance of the wild-type strain Megasphaera elsdenii H6. The initial mutant population of M. elsdenii H6 was treated with UV irradiation and nitrosoguanidine (NTG), resulting in an improved population producing more propionate than the original strain at pH 5.5. These mutants were used as the starting...
