For the full versions of these articles see bmj.com Egg allergy affects about 2.6% of preschool children by 3 years of age, and influenza immunisation using egg based vaccines has been classified as a " relative contra indication " (prescribe with extra caution) in this patient group. 1 Until now the numbers of children with egg allergy requiring immunisation has been low, but this may change w...

BACKGROUND Rhaponticum cathamoides (RC) is an endemic wild Siberian herb with marked medicinal properties that are still poorly understood. The aim of this study is to investigate the therapeutic potential of RC extract (ERC) compared to the effects of Glycyrrhiza glabra (EGG) and Punica granatum extracts (EPG) in a rat model with high-fat diet-(HFD)-induced signs of metabolic syndrome; therefo...

Pasteurella multocida the etiological agent of fowl cholera was isolated from 16 layer flocks in and around Faisalabad. The flocks ranged in age from 18-24 weeks. Increased mortality and considerable drop in egg production were the main clinical signs in all affected flocks. Bacterial isolation and identification was conducted on the basis of cultural, morphological and biochemical characterist...

We previously demonstrated that a systematic passage of a pathogenic field isolate of Sendai virus (SeV), the Hamamatsu strain, in embryonated eggs caused attenuation of virulence to mice, and we isolated viral clones of distinct virulence (K. Kiyotani et al. Arch. Virol. 146:893-908, 2001). One of the clones, E15cl2, which was obtained from the virus at the 15th egg passage of E0, the parental...

False positive raised complement fixation titres to egg-grown virus preparations were found in six pigeon fanciers suffering from extrinsic allergic alveolitis but not in six similar budgerigar fanciers. The raised titres in the pigeon fanciers fell fourfold over a short interval in the absence of avian exposure and were attributable to antibodies directed against antigens from hen's egg in whi...

Determination of the avian influenza (AI) status of a flock has traditionally been done by detection of serum antibodies. However, for many diseases, detection of antibodies in egg yolk has been effective in monitoring the disease status of laying flocks. This study compared the utility of egg yolk vs. serum for determining AI status in laying hen flocks. Specific-pathogen-free white leghorn he...

Background Influenza, or “flu”, is an upper respiratory tract infection caused by a virus belonging to the family of Orthomyxoviridae. Influenza can pose a serious risk to the health of mainly the elderly, the very young, and to people suffering from medical conditions (e.g. weak immune system). For example, seasonal influenza strains are fatal to more than 50,000 people annually in the United ...

conclusions the prevalence of pandemic influenza viruses in recent years has caused financial losses as well as mortalities around the world. this shows the importance of the rapid diagnosis of common serotypes in our society. using real-time rt-pcr is recommended for the early diagnosis and the rapid identification of the individuals infected with pandemic influenza virus. background timely di...
