Reconstructing the evolutionary history of pandemic foot-andmouth disease viruses: the impact of recombination within the emerging O/ME-SA/Ind-2001 lineage

Foot-and-mouth disease (FMD) is a highly contagious disease of livestock affecting animal production and trade throughout Asia and Africa. Understanding FMD virus (FMDV) global movements and evolution can help to reconstruct the disease spread between endemic regions and predict the risks of incursion into FMD-free countries. Global expansion of a single FMDV lineage is rare but can result in severe economic consequences. Using extensive sequence data we have reconstructed the global space-time transmission history of the O/ME-SA/Ind-2001 lineage (which normally circulates in the Indian sub-continent) providing evidence of at least 15 independent escapes during 2013–2017 that have led to outbreaks in North Africa, the Middle East, Southeast Asia, the Far East and the FMD-free islands of Mauritius. We demonstrated that sequence heterogeneity of this emerging FMDV lineage is accommodated within two co-evolving divergent sublineages and that recombination by exchange of capsid-coding sequences can impact upon the reconstructed evolutionary histories. Thus, we recommend that only sequences encoding the outer capsid proteins should be used for broad-scale phylogeographical reconstruction. These data emphasise the importance of the Indian subcontinent as a source of FMDV that can spread across large distances and illustrates the impact of FMDV genome recombination on FMDV molecular epidemiology.

Whole Genome Sequence Analysis of the First Vancomycin-Resistant Enterococcus faecium Isolates from a Libyan Hospital in Tripoli

Abstract The purpose of the study was to investigate the molecular characteristics and genetic relatedness of the first reported cases of vancomycin-resistant enterococci (VRE) from the Tripoli Medical Center, Libya. In total, 43 VRE isolates were obtained from various clinical sites throughout the years 2013-2014, including 40 vanA-type and 2 vanB-type vancomycin-resistant Enterococcus faecium isolates and 1 vanC1-type Enterococcus gallinarum. Of the 42 E. faecium, 19 isolates were subjected to whole genome sequencing. Core genome multilocus sequence typing (cgMLST) analysis revealed three sequence clusters (SCs) of clonally related isolates, which were linked to different hospital wards. The first two VRE isolates, isolated early 2013 from patients in the medical intensive care unit, were grouped in SC1 (MLST [ST] 78, vanB) and differed in only 3 of 1423 cgMLST alleles. The SC2 (n = 16, special care baby unit, neonatal intensive care unit, pediatric surgery ward, and oncology ward) and SC3 (n = 1, antenatal ward) were all ST80 vanA-VRE, but the single SC3 isolate differed in 233 alleles compared with SC2. Within SC2, isolates differed in 1-23 alleles. Comparison with a larger database of E. faecium strains indicated that all isolates clustered within the previously defined hospital clade A1. A combination of Resfinder and mlplasmid analysis identified the presence of resistance genes on different plasmid predicted genetic elements among different SCs. In conclusion, this study documents the first isolates causing outbreaks with VRE in the Libyan health care system. Further surveillance efforts using molecular typing methods to monitor spread of multidrug-resistant bacteria in the Libyan health care system are urgently needed.

COVID-19 and African Immigrants in North Africa: A Hidden Pandemic in a Vulnerable Setting

Since being declared a pandemic in March 2020, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes the disease known as coronavirus disease (COVID-19), has brought difficult situations for citizens of nations worldwide. The effects, however, may be more severe for vulnerable communities, such as immigrants, who are already in desperate situations and under deteriorating conditions. There are still very limited data on how the pandemic is impacting migrant communities. Immigrant camps foster an environment that poses a great threat to the health of their inhabitants, especially at the time of a pandemic. Overcrowding, poor sanitation, inadequate health care, and difficulty containing contagious diseases are well documented in African immigration detention centers. Furthermore, they are unlikely to take priority in a moment in which governments are mobilizing all resources to care for their citizens. Their situation is even more complicated if they are hosted in corridors plagued by war, as in North Africa
