A Gallus gallus Model for Determining Infectivity of Zoonotic Campylobacter
Frontiers in Microbiology, 2019 To better understand public health implications of waterfowl as reservoirs for zoonotic sources of Campylobacter in recreational waters, we developed a Gallus gallus (chick) model of infection to assess the pathogenicity of environmental isolates of ...

Infectivity of Norovirus GI and GII from Bottled Mineral Water during a Waterborne Outbreak, Spain
Emerging Infectious Diseases, 2020 During a waterborne outbreak of norovirus in Spain, we estimated 50% illness doses for a group of exposed (secretor) persons to be 556 (95% CI 319–957) genome copies/day for norovirus GI and 2,934 (95% CI 1,683–5,044) genome copies/day for norovirus GII.
