BACKGROUND Treatment of low-risk febrile episodes with oral administered antibiotics at home is a new approach in pediatric oncology and protective isolation is loosened in more centers. The impact of viral respiratory infections in febrile diseases in this population is still unclear in terms of occurrence and morbidity. PROCEDURE A prospective follow-up study of all febrile episodes during ...

Sambucus nigra (elder) are broadly used species to treat microbial infections. Thepotential antiviral activity and mechanism action of elder fruit (EF) in human epithelium cell(A549) cultures infected with H9N2 influenza virus were determined. The effect of variousconcentrations of EF on influenza virus replication was examined by using virus titration,quantitative real time RT-PCR, fusion and ...

The identification of honeybee viruses is of serious importance, particularly considering the lack of information on the natural incidence of viral infections in honeybee populations worldwide. Moreover, the global spread of Varroa destructor in honeybee colonies has a significant effect on the viral infection. In the present study, 160 samples of adult bee from apparently healthy colonies but ...

background and aims: herpes simplex virus (hsv) is responsible for several significant human viral diseases, with severity ranging from subclinical to fatal infection. herpes simplex virus type 2 (hsv2) infections are more commonly seen in association with the genitalia and surrounding areas, and can be transmitted to newborns during childbirth. generalized infections in newborns are also predo...

Bovine herpes viruses belong to the family Herpesviridae. Bovine herpes virus 1 (BHV-1) is of world wide distribution and causes a wide range of diseases in cattle namely respiratory disease, keratoconjunctivitis and reproductive diseases including infectious pustular vulvovaginitis (IPV) in cows, infectious pustular balonoposthitis (IPB) in bulls and abortions. DNA studies of BHV-1 have reveal...

A technique using indirect immunoperoxidase antibody was developed for the detection of specific serum IgA antibody to Epstein-Barr virus capsid antigen and early antigen. The IgA technique was compared with an immunofluorescence antibody method. Epstein-Barr virus IgA antibody against viral capsid antigen was detected in all nine patients with Epstein-Barr virus associated undifferentiated nas...

RS virus was isolated from 10 5% of the specimens examined in the MRC/PHLS hospital survey and from 0 9% of those in the general practice survey. The highest isolation rates were in infants with lower respiratory tract infections. Dyspnoea, wheezing and cough were the predominant clinical features. The differences in the rates between hospital and general practice and newer methods of diagnosis...

In recent years, antibiotics have proved effective against many bacterial and all rickettsial infections of man, but are only of limited value in virus infections. The so-called broad spectrum antibiotics-aureomycin, terramycin and chloramphenicol-are effective against the viruses of the psittacosis-lymphogranuloma group and those causing primary atypical pneumonia. Many substances are therefor...

The possibility of an association between virus infections during pregnancy and subsequent malignant disease in the child has been investigated using retrospective data from the Oxford Survey of Childhood Cancers. Such an association appears to exist for influenza, chickenpox, and possibly rubella. For influenza and rubella the estimated risk is small; the data do not permit an estimate to be m...

We retrospectively reviewed eight prospective epidemiological studies conducted between 1991 and 1995 for dual respiratory virus infection (DRVI) to determine the frequency, associated comorbid conditions, clinical presentations, and morbidity related to DRVI among immunocompetent persons. Two viruses were identified as the cause of 67 (5.0%) of 1,341 acute respiratory virus infections. DRVI wa...
