[ 1 ] - Molecular evaluation of M2 protein of Iranian avian influenza viruses of H9N2 subtype in order to find mutations of adamantane drug resistance

Background: The H9N2 subtype of influenza A viruses is considered to be widespread in poultry industry. Adamantane is a group of antiviral agents which is effective both in prevention and treatment of influenza A virus infections. These drugs inhibit M2 protein ion channel which has role on viral replication. OBJECTIVES: The main objective of this study is to evaluate M gene of avian influenza ...

[ 2 ] - تولید تخم مرغ ایمن سازی شده علیه E. coli K99 و Salmonella enteritidis

باکتری­های E.coli K99 و Salmonella enteritidis از عوامل اصلی اسهال گوساله­ها می­باشند. جهت پیشگیری از وقوع بیماری­های ناشی از این عوامل از روش­های زیادی از جمله واکسیناسیون و انتقال ایمنی غیر فعال ( passive ) می­توان استفاده نمود. به­همین منظور در سال­های اخیر بحث استفاده از تخم مرغ ایمن سازی شده در جیره غذایی گوساله­های حساس مطرح شده است. به­منظور تهیه آنتی ژن، باکتری­های  E.coli K99 وSalmonel...

[ 3 ] - Sequencing and In Silico Multi-aspect Analysis of S1 Glycoprotein in 793/B Serotype of Infectious Bronchitis Virus Isolated From Iran in 2003 and 2011

Infectious bronchitis (IB) is an acute, highly contagious, and economically important viral disease of chickens. The S1 subunit from Spike (S) protein plays the major role in protective immunity and is involved in the host-virus interactions, as well as infectious bronchitis virus (IBV) serotyping. Aim of the present study was multi-aspect analysis of the molecular and immunological features of...

[ 4 ] - RAPD-PCR and Drug Resistance Pattern of Staphylococcus aureus Isolates Recovered from Companion and Wild Birds

BACKGROUND: Staphylococcus aureus is a highly versatile pathogen of a large number of domestic ani- mals, including avian species. There is limited information about S. aureus isolated from companion and wild birds in Iran. OBJECTIVES: The aim of this study was to determine drug resistance and random-amplified polymorphic DNA-PCR (RAPD-P...
