Abstract
A moderately halophilic and strictly aerobic bacterium was isolated from a human stool as part of a study on the diagnosis of childhood malnutrition in Mali. Strain Marseille-Q1616T is a Gram-stain-positive, rod-shaped, catalase-positive and oxidase-negative bacterium. It has a genome size of 3.91 Mbp with 39.79% G+C content, which contains 3954 protein-coding genes including genes encoding phosphomycin resistance and Listeria monocytogenes, 16 rRNA genes and 64 tRNA genes. Strain Marseille-Q1616T exhibited a 96.3% 16S rRNA gene sequence similarity and shared an OrthoANI value of 70.64% (the highest observed) with Virgibacillus kekensis, the phylogenetically closest validly published species. Based on phenotypic and phylogenetic evidence and genomic average nucleotide identity values, we suggest the creation of a new species within the Virgibacillus genus, named Virgibacillus doumboii sp. nov., type strain Marseille-Q1616T (= CSURQ1616).

Abstract
During a case–control study on severe acute malnutrition, strain Marseille-Q1233 was isolated. It is a Gram-positive, rod-shaped and halophilic bacillus isolated from a stool sample of Malian child under the age of 5. The fatty acid profile of the strain consisted of C15:0-anteiso and C14:0-iso as major components. Digital DNA-DNA hybridization and average nucleotide identity calculation showed 23.10% and 80.81% similarity respectively between strain Marseille-Q1233 and Virgibacillus siamensis strain Marseille-P2607, the phylogenetically closely related species with standing in nomenclature. On the basis of these results, we report the description of Virgibacillus ihumii sp. nov. strain Marseille-Q1233 as a new bacterial species.

Abstract
Strain Marseille-Q1234T is a new species from the genus Halobacillus that was isolated in 2019 from a stool sample in a healthy Malian child <5 years old. Cells are Gram-positive and strictly halophilic bacilli. Strain Marseille-Q1234T exhibits 98.46% 16S rRNA gene sequence similarity to Halobacillus naozhouensis strain JSM 071068T (NR_116505.1), the phylogenetically closely related species with standing in nomenclature. Based on the phenotypic and phylogenetic evidence, OrthoANI values and results of the biochemical tests, the new species is named Halobacillus ihumii sp. nov., for which strain Marseille-Q1234T (= CSURQ1234) is proposed as the type strain.

Abstract
Four strains isolated by microbial culturomics from breast milk of healthy mothers from Mali were not identified and characterized by taxono-genomics. This led us to propose the new genera and species Lactimicrobium massiliense, Anaerolactibacter massiliensis and Galactobacillus timonensis containing type strain Marseille-P4301T (CSUR P4301T), Marseille-P4302T (CSUR P4302T) and Marseille-P4641T (CSUR P4641T), respectively. The strain Marseille-P4482 represents a novel species, Acidipropionibacterium timonense, in a previously known genus with type strain being Marseille-P4482T (CSUR P4482T).

Abstract
Background Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) share common risk factors. The parallel description of their frequency over time may help capture their similarities and differences. Methods Using data from the National Transfusion Center of Abidjan, we estimated the following over a 20-year period: (1) the prevalence of HIV and hepatitis B surface antigen (HBsAg) positivity at first contact; and (2) the incidence of HIV and HBsAg seroconversion in negative first-time blood donors. Results Between 1992 and 2012, 422319 donors (men [M] = 74%) provided 1063825 blood donations. For first-time donors, HIV prevalence decreased from 7.1% (M = 5.9%, women [W] =11.0%) in 1992-1994 to 1.1% (M = 0.8%, W = 2.0%) in 2010-2012. Prevalence of HBsAg positivity remained stable at 10.8% (M = 11.7%, W = 7.3%) in 1992-1994 to 11.1% (M = 12.5%, W = 7.1%) in 2010-2012. Among regular donors (N = 129256), the incidence of becoming HIV or HBsAg positive, respectively, decreased from 4.9 per 100 (M = 4.5, W = 8.6) and 7.3 per 100 person-years (M = 7.8, W = 2.3) in 1992-1994 to 0.07 (M = 0.06, W = 0.11) and 0.2 per 100 person-years (M = 0.2, W = 0.2) in 2010-2012. Conclusions Human immunodeficiency virus prevalence and incidence decreased dramatically over time, whereas HBV prevalence remained stable. Incidence of HBsAg seroconversion, although decreasing, still reached unexpected levels, suggesting that the risk of HBV infection in adults may be higher than expected. Hepatitis B surface antigen-negative blood-donors should be offered HBV vaccination.

Abstract
BACKGROUND In sub-Saharan Africa, the burden of human immunodeficiency virus (HIV)-associated tuberculosis is high. We conducted a trial with a 2-by-2 factorial design to assess the benefits of early antiretroviral therapy (ART), 6-month isoniazid preventive therapy (IPT), or both among HIV-infected adults with high CD4+ cell counts in Ivory Coast. METHODS We included participants who had HIV type 1 infection and a CD4+ count of less than 800 cells per cubic millimeter and who met no criteria for starting ART according to World Health Organization (WHO) guidelines. Participants were randomly assigned to one of four treatment groups: deferred ART (ART initiation according to WHO criteria), deferred ART plus IPT, early ART (immediate ART initiation), or early ART plus IPT. The primary end point was a composite of diseases included in the case definition of the acquired immunodeficiency syndrome (AIDS), non-AIDS-defining cancer, non-AIDS-defining invasive bacterial disease, or death from any cause at 30 months. We used Cox proportional models to compare outcomes between the deferred-ART and early-ART strategies and between the IPT and no-IPT strategies. RESULTS A total of 2056 patients (41% with a baseline CD4+ count of ≥500 cells per cubic millimeter) were followed for 4757 patient-years. A total of 204 primary end-point events were observed (3.8 events per 100 person-years; 95% confidence interval [CI], 3.3 to 4.4), including 68 in patients with a baseline CD4+ count of at least 500 cells per cubic millimeter (3.2 events per 100 person-years; 95% CI, 2.4 to 4.0). Tuberculosis and invasive bacterial diseases accounted for 42% and 27% of primary end-point events, respectively. The risk of death or severe HIV-related illness was lower with early ART than with deferred ART (adjusted hazard ratio, 0.56; 95% CI, 0.41 to 0.76; adjusted hazard ratio among patients with a baseline CD4+ count of ≥500 cells per cubic millimeter, 0.56; 95% CI, 0.33 to 0.94) and lower with IPT than with no IPT (adjusted hazard ratio, 0.65; 95% CI, 0.48 to 0.88; adjusted hazard ratio among patients with a baseline CD4+ count of ≥500 cells per cubic millimeter, 0.61; 95% CI, 0.36 to 1.01). The 30-month probability of grade 3 or 4 adverse events did not differ significantly among the strategies. CONCLUSIONS In this African country, immediate ART and 6 months of IPT independently led to lower rates of severe illness than did deferred ART and no IPT, both overall and among patients with CD4+ counts of at least 500 cells per cubic millimeter.

Abstract
BACKGROUND Blackwater fever is a rare but serious form of malaria in children. Diagnosis relies on clinical symptoms and on the color of the urines. OBJECTIVES To describe blackwater fever in children, a disease whose prevalence seems to be increasing. METHOD We report 3 cases of blackwater fever observed in our institution. RESULTS In 2 cases, acute renal insufficiency with oligoanuria was observed. In all the 3 cases, treatment with quinine was stopped and replaced by injectable artemether. Evolution was dependent on renal function, and included in 1 patient neurological sequels consisting in aphasia. CONCLUSION Blackwater fever is a severe affection whose diagnosis should be evoked using the color of urine. Evolution is usually favorable in the pediatric population, when adequate care can be provided.

Abstract
The assessment of the viral residual risk from blood products is an assessment indicator of the quality management system and of the availability process of these products. Assessments of HIV, HBV and HCV viruses transmission risks through blood transfusion are calculated after the setting of a quality approach at the Abidjan NBTC. The method used estimates the risk of a donation made during a period immunologically silent. The residual risks for HIV, HBV, and HCV viruses have been estimated by multiplying the incidence rate for 100,000 people per year by the respective durations of the serological windows. The data received from the Abidjan Center's information processing system (Progesa 4.4d of MAK SYSTEM) go from 2002 to 2004 period. The residual risks are 1/5780 donations for HIV and 1/406 donations for the HCV, then 1/383 donations for the HBV. The residual risk for the HIV is almost four times reduced compared to that of 1997. The results show not only the importance of the transmission risk of HIV, HBV and HCV viruses through blood products, but also the necessity to set a quality management system in endemic countries of Sub-Saharan Africa.

Abstract
OBJECTIVE To estimate the risk of infection with HIV (HIV 1 or HIV 2, or both) from transfusion of a screened unit of blood in a high prevalence area in west Africa. DESIGN Retrospective cohort study for January-July 1991. SETTING National Blood Transfusion Centre, Abidjan, Côte d'Ivoire. SUBJECTS Repeat donors (5831 units of blood) and first time donors (5076 units) in the first five months of 1991. MAIN OUTCOME MEASURES Prevalence and estimated incidence of HIV infection in repeat and first time donors; estimated rate of potentially infected, HIV antibody negative units; and rate of (false negative) potentially infected units assuming a laboratory test sensitivity of 99%. RESULTS Overall HIV prevalence was 11.0% in first time donors and 2.1% in repeat donors. In the first seven months of 1991, 29 HIV antibody positive (27 HIV 1, 1 HIV 2, 1 dually reactive) donors with a seronegative unit of blood earlier in the year were identified; 26 had donated blood eight weeks or less before their estimated dates of seroconversion and may have been infectious (minimum rate 26/5831 (4.5/1000 potentially infected units)). Estimated incidence of infection in repeat donors was 1.2-2.5%. Laboratory test insensitivity would result in an estimated 1.1/1000 false negative units from first time donors and 0.2/1000 units from regular donors. The overall rate of potentially infected units (all donors, seroconversions, and errors) was estimated at 5.4-10.6/1000. CONCLUSIONS The risk of HIV infection from a single unit of blood remains substantial (5.4-10.6/1000 units). To prevent infection from blood transfusion in areas of high incidence and prevalence of HIV all but absolutely essential transfusions should be avoided, and donors with low incidence of HIV infection should be selected.
