Journal ArticleDOI
Seroepidemiology for MERS coronavirus using microneutralisation and pseudoparticle virus neutralisation assays reveal a high prevalence of antibody in dromedary camels in Egypt, June 2013
Ranawaka A.P.M. Perera,Peigang Wang,Peigang Wang,Mokhtar R. Gomaa,Rabeh El-Shesheny,Ahmed Kandeil,Ola Bagato,Lewis Y. Siu,Mahmoud Shehata,Ahmed S. Kayed,Yassmin Moatasim,Ming Yuan Li,Leo L.M. Poon,Yi Guan,Richard J. Webby,Mohamed A. Ali,J. S. Peiris,Ghazi Kayali +17 more
TL;DR: The newly developed ppNT assay does not require Biosafety Level 3 containment and is thus a relatively high-throughput assay, well suited for large-scale seroepidemiology studies which are needed to better understand the ecology and epidemiology of MERS-CoV.
Journal ArticleDOI
Active Surveillance for Avian Influenza Virus, Egypt, 2010-2012
Ghazi Kayali,Ahmed Kandeil,Rabeh El-Shesheny,Ahmed S. Kayed,Mokhtar Gomaa,Asmaa M. Maatouq,Mahmoud Shehata,Yassmin Moatasim,Ola Bagato,Zhipeng Cai,Adam Rubrum,M. A. Kutkat,Pamela McKenzie,Robert G. Webster,Richard J. Webby,Mohamed A. Ali +15 more
TL;DR: Genetic and antigenic analyses of viruses revealed that influenza A(H5N1) clade 2.2.1 viruses are dominant and that all subtype H9N2 viruses are G1-like, which poses concern for potential reassortment.
Journal ArticleDOI
Avian Influenza A(H5N1) and A(H9N2) Seroprevalence and Risk Factors for Infection Among Egyptians: A Prospective, Controlled Seroepidemiological Study
Mokhtar R. Gomaa,Ahmed S. Kayed,Mona A. Elabd,Dina Abu Zeid,Shaimaa A. Zaki,Amira S. El Rifay,Lobna S. Sherif,Pamela McKenzie,Robert G. Webster,Richard J. Webby,Mohamed A. Ali,Ghazi Kayali +11 more
TL;DR: The number of humans infected with avian influenza viruses is much larger than the number of reported confirmed cases, and in an area where these viruses are enzootic in the poultry, human exposure to and infection withAvian influenza becomes more common.
Journal ArticleDOI

Ghazi Kayali,Ahmed Kandeil,Rabeh El-Shesheny,Ahmed S. Kayed,Asmaa M. Maatouq,Zhipeng Cai,Pamela McKenzie,Richard J. Webby,Samir El Refaey,Amr Kandeel,Mohamed A. Ali +10 more
TL;DR: An aggressive plan to curb these infections in poultry is urgently needed.
Journal ArticleDOI
Systematic, active surveillance for Middle East respiratory syndrome coronavirus in camels in Egypt
Mohamed A. Ali,Mahmoud Shehata,Mokhtar R. Gomaa,Ahmed Kandeil,Rabeh El-Shesheny,Ahmed S. Kayed,Ahmed Nageh El-Taweel,Mohamed Atea,Nagla Hassan,Ola Bagato,Yassmin Moatasim,Sara H. Mahmoud,Omnia Kutkat,Asmaa M. Maatouq,Ahmed Osman,Pamela McKenzie,Richard J. Webby,Ghazi Kayali +17 more
TL;DR: The hypothesis that camels are a reservoir for MERS-CoV and that camel trade is an important route of introducing the virus into importing countries is supported and findings related to waning antibodies and re-infection have implications for camel vaccine development, disease management and zoonotic threat.
