Escobar-Gutierrez, Alejandro;Vaughan, Gilberto;Couvin, David;Gonçalves Rossi, Livia Maria;Gomez-Bustamante, Adriana;Vazquez-Chacon, Carlos A;Gonzalez-Macal, Gabriela A;Martínez-Guarneros, Armando;De-la-Cruz López, Juan J;González-Y-Merchand, Jorge A;Rastogi, Nalin;Rivera-Gutierrez, Sandra;Muñiz-Salazar, Raquel

Here, we describe the molecular characterization of six human Mycobacterium bovis clinical isolates, including three multidrug resistant (MDR) strains, collected in Mexico through the National Survey on Tuberculosis Drug Resistance (ENTB-2008), a nationally representative survey conducted during 2008-2009 in nine states with a stratified cluster sampling design. The genetic background of bovine M. bovis strains identified in three different states of Mexico was studied in parallel to assess m...

Multidrug-resistant tuberculosis and migration to Europe
Hargreaves, Sally;Friedland, Jon S;Nathavitharana, Ruvandhi R;Nellums, Laura B;Olaru, Ioana D;Lönnroth, Knut;Norredam, Marie

Multidrug-resistant tuberculosis (MDR-TB) in low-incidence countries in Europe is more prevalent among migrants than the native population. The impact of the recent increase in migration to EU and EEA countries with a low incidence of TB (fewer than 20 cases per 100,000 [1]) on MDR-TB epidemiology is unclear. This narrative review synthesises evidence on MDR-TB and migration identified through an expert panel and database search. A significant proportion of MDR-TB cases in migrants result fro...

Spatial Dynamics and High Risk Transmission Pathways of Poliovirus in Nigeria 2001-2013
Grassly, Nicholas C;Shuaib, Faisal;Abanida, Emmanuel;Mwanza, Michael;Mangal, Tara D;Aylward, R Bruce;Pate, Muhammed A

The polio eradication programme in Nigeria has been successful in reducing incidence to just six confirmed cases in 2014 and zero to date in 2015, but prediction and management of future outbreaks remains a concern. A Poisson mixed effects model was used to describe poliovirus spread between January 2001 and November 2013, incorporating the strength of connectivity between districts (local government areas, LGAs) as estimated by three models of human mobility: simple distance, gravity and rad...
