    Abstract We present a phylodynamic and phylogeographic analysis of this new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus in this report. A tree of maximum credibility was constructed using the 72 entire genome sequences of this virus, from the three countries (China, Italy, and Spain) available as of 26 March 2020 on the GISAID reference frame. To schematize the current SARS-CoV-2 migration scenario between and within the three countries chosen, using the multitype bearth-death model implemented in BEAST2. Bayesian phylogeographic reconstruction shows that SARS-CoV-2 has a rate of evolution of 2.11 × 10

    Abstract Despite the difficulties and the absence of credible scientific information concerning bovine tuberculosis in Algeria, our cross-sectional and inferential study, which is estimated to be a first in Algeria, affected three major semi-intensive regions in East of Algeria, by analyzing 21 holdings which grouped 516 cattle in an intensive and semi-intensive breeding character over a period of 12 months, in order to estimate the seroprevalence and the risk factors those influence the emergence of the disease in these regions. A serological test (ELISA) was carried out on all collected sera, after a stratified two-level sampling. A generalized linear mixed model was used to identify risk factors associated with animal-level positivity. A multivariate descriptive analysis (MCA) was used to identify farm clusters associated with bTB seroprevalence. The results obtained allow us to classify Algeria on the epidemiological level in the field of bovine tuberculosis, in an intermediate situation with a seroprevalence rate of 3.49 % (95 % CI : 1,91, 507); between industrialized countries where the seroprevalence is mostly very low below 0,1% and developing countries with very high seroprevalence such as African-Asian countries. This intermediate epidemiological position is influenced by certain risk factors that are integrated into the three mechanisms commonly known by the scientific community: "contamination by the introduction of an animal"; "neighborhood contamination"; "recurrence". But what characterizes this study is the obtaining of a "Animals purchased from a country listed as not OTF" factor that has returned as a highly protective factor and contributed to the decrease in this seroprevalence, and put Algeria in an intermediate epidemiological situation according to our study, and this is due to a purchase channeled by the state which is exclusive of the countries certified OTF by the OIE.

    Abstract Our study included 2465 blood donors unrelated from both sexes, originating from Msila (Algeria), at Msila Blood Transfusion Center (CTS), with the aim of performing an anthropogenetic characterization of the population of M'sila, by studying the three-erythrocyte polymorphic systems ABO, Rhesus, and Kell with their allele frequencies. This allowed us to demonstrate after a multi-varied comparative analysis through principal components analysis (PCA) and hierarchical cluster analysis (HCA) On the one hand, comparing the population of Msila to the different regions of Algeria where we found a genetic proximity with the great south of Algeria going towards the south-east of Algeria. On the other hand, the comparative analysis of Msila's population with other populations in the world based on historical, geographical and cultural profile, by building a tri-hybrid potential parenting model (North Africa, Mediterranean and Middle orient) through the three blood systems, allowed us to identify four potential parents including Egypt and Libya (North Africa) and Saudi Arabia and South Yemen (Middle East), Regarding the third strand of our tri-hybrid model, we did not find any potential parental link with the northern shore of the Mediterranean (southern Europe) despite the historical and geographical link that exists. This study allowed us to share the map of Algeria genetically into two blocks: a North block and a South block. It also allowed us to trace a retrograde genetic route through the time of the M'sila population, thus determining these potential parental origins.

    Abstract We present a phylodynamic and phylogeographic analysis of this new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus in this report. A tree of maximum credibility was constructed using the 72 entire genome sequences of this virus, from the three countries (China, Italy, and Spain) available as of 26 March 2020 on the GISAID reference frame. To schematize the current SARS-CoV-2 migration scenario between and within the three countries chosen, using the multitype bearth-death model implemented in BEAST2. Bayesian phylogeographic reconstruction shows that SARS-CoV-2 has a rate of evolution of 2.11 × 10-3 per sites per year (95% highest posterior density: 1.56 × 10-3 to 3.89 × 10-3 ), and a geographic origin in Shanghai, where time until the most recent common ancestor (tMRCA) emerged, according to the analysis of the molecular clock, around 13 November 2019. While for Italy and Spain, there are two tMRCA for each country, which agree with the assumption of several introductions for these countries. That explains also this very short period of subepidermal circulation before the recent events. A total of 8 (median) migration events occurred during this short period, the largest proportion of which (6 events [75%]) occurred from Shanghai (China) to Spain and from Italy to Spain. Such events are marked by speeds of migration that are comparatively lower as compared with that from Shanghai to Italy. Shanghai's R0 and Italy's are closer to each other, though Spain's is slightly higher. All these results allow us to conclude the need for an automatic system of mixed, molecular and classical epidemiological surveillance, which could play a role in this global surveillance of public health and decision-making.
