Emergence of highly pathogenic H5N2 and H7N1 influenza a viruses from low pathogenic precursors by serial passage in ovo

Laleye, Agnes Tinuke; Abolnik, Celia (Public Library of Science, 2020-10)

Highly pathogenic (HPAI) strains emerge from their low pathogenic (LPAI) precursors and cause severe disease in poultry with enormous economic losses, and zoonotic potential. Understanding the mechanisms involved in HPAI ...
The incursion and spread of highly pathogenic avian influenza H5N8 clade 2.3.4.4 within South Africa

Abolnik, Celia; Pieterse, Renee; Peyrot, B.M.; Choma, P.; Phiri, Thandeka Precious; Ebersohn, Karen; Van Heerden, C.J.; Vorster, A.A.; Van der Zel, G.; Geertsma, P.J.; Laleye, Agnes Tinuke; Govindasamy, Krpasha; Rauffy, D.L. (American Association of Avian Pathologists, 2019)

The report of a mass die-off of white-winged terns (Chlidonias leucopterus) along the shores of Lake Victoria in Uganda in January 2017 was a warning that highly pathogenic avian influenza (HPAI) H5N8 clade 2.3.4.4 had ...
National surveillance and control costs for highly pathogenic avian influenza H5N1 in poultry : a benefit-cost assessment for a developing economy, Nigeria

Fasanmi, Olubunmi Gabriel; Kehinde, Olugbenga O.; Laleye, Agnes Tinuke; Ekong, Bassey; Ahmed, Syed Sayeem Uddin; Fasina, Folorunso Oludayo (Elsevier, 2018-08)

We conducted benefit-cost analysis of outbreak and surveillance costs for HPAI H5N1in poultry in Nigeria. Poultry's death directly cost US$ 939,734.0 due to outbreaks. The integrated disease surveillance and response ...
Propagation of avian influenza virus in embryonated ostrich eggs

Laleye, Agnes Tinuke; Adeyemi, Modupeore; Abolnik, Celia (AOSIS OpenJournals, 2022-12-08)

Influenza A viruses (IAVs) are typically isolated and cultured by successive passages using 9- to 11-day-old embryonated chicken eggs (ECEs) and in 14-day old ECEs for virus mutational studies. Real-time reverse ...
Systematic review and meta-analyses of cases and deaths associated with highly pathogenic avian influenza H5N1 in humans and poultry

Fasanmi, Olubunmi Gabriel; Laleye, Agnes Tinuke; Fasina, Folorunso Oludayo (CABI, 2016)

From 2003 to date (2015), confirmed highly pathogenic avian influenza (HPAI) H5N1 outbreaks in poultry and humans have been reported, however, certain quantitative parameters remain lacking. We obtained 846 reports of HPAI ...
A two-year monitoring period of the genetic properties of clade 2.3.2.1c H5N1 viruses in Nigeria reveals the emergence and co-circulation of distinct genotypes

Laleye, Agnes Tinuke; Joannis, Tony Manuel; Shittu, Ismaila; Meseko, Clement Adebajo; Zamperin, Gianpiero; Milani, Adelaide; Zecchin, Bianca; Fusaro, Alice; Monne, Isabella; Abolnik, Celia (Elsevier, 2018-01)

Phylogenetic analyses of the complete genomes of the highly pathogenic avian influenza (HPAI) 2.3.2.1c H5N1 virus strains causing outbreaks in Nigeria's poultry population from 2014 to 2016 showed evidence of distinct ...
