RESUMEN
In September 2017, an outbreak with high mortality, which showed the typical signs of ND, occurred among a flock of more than 2000 Eurasian collared doves in Konarak, southeast of Iran. A confirmed pigeon paramyxovirus type 1 strain was isolated from the brain tissues of the dead doves. The isolate, which was called Pigeon/Iran/Konarak/Barin/2017, was classified as a highly velogenic NDV. Complete genome sequencing and phylogenetic analysis showed that the isolate belonged to subgenotype XXI.2, which has never been reported from Iran before. The isolate had the highest homology (96.15%) with early 2010s Italian isolates.Further studies will be required to understand the diversity better.
RESUMEN
<p><b>OBJECTIVE</b>To test the antibodies against newcastle disease virus (NDV) and avian influenza virus (AIV, H9N2) in the unvaccinated backyard poultry in Bushehr province, Iran from 2012 to 2013.</p><p><b>METHODS</b>A total of 1 530 blood samples from unvaccinated backyard chickens in Bushehr province, south of Iran, were tested for antibodies against NDV and AIV (H9N2) by hemagglutination inhibition test according to International Epizootic Office (OIE) recommendation.</p><p><b>RESULTS</b>Of these, 614 (40.13%) and 595 (39.00%) were positive for NDV and AIV (H9N2) respectively.</p><p><b>CONCLUSIONS</b>The findings of the present study indicated that NDV and AIV (H9N2) were endemic and widely distributed in backyard areas of Bushehr province which should be incorporated in the control strategies. Further studies are needed to identify the circulating virus genotypes, model their transmission risk, provide adapted control measures and design proper and applicable vaccination program.</p>
RESUMEN
Crimean-Congo hemorrhagic fever [CCHF] virus causes a severe hemorrhagic syndrome in humans with fatality rate up to 50%. Its transmission to humans is through the bite of Ixodid ticks or by contact with blood or tissues from infected livestock. By a nosocomial transmission of Crimean-Congo hemorrhagic fever [CCHF], a health care worker was infected in December 2008 due to a re-emerging outbreak of CCHF in Fars province, Iran. After admission of probable CCHF cases in a local hospital, one of the nurses contributed in taking care of the patients was infected with CCHF, though it seems that she had not had direct contact with blood and secretions of CCHF patients. The laboratory detected anti-CCHF virus IgM antibody through specific ELISA and also the CCHF virus genome in her serum by real-time and gel-based RT-PCR. She was improved by an alert and on time clinical diagnosis and treatment. We recommend that in outbreaks of CCHF, care to prevent airborne transmission should be kept in mind
