The characterization of the relationships between mineralization and hydrothermal alteration is an essential element in understanding gold deposits. in south-west Burkina faso, the napélépéra mineralisation, the mobility of chemical elements and alteration-mineralization relationships were studied by means of selected core drilling and geochemical analyses using iCP-MS (inductively Coupled Plasma Mass Spectrometry) and iCP-AES (inductively coupled plasma atomic emission spectroscopy). The mineralised granodiorite is grey porphyroid with quartz, plagioclase, biotite and amphibole. it is metaluminous and located in the tholeiitic series. The na2O + CaO versus Fe2O3 + MgO alteration diagram divides the samples according to alteration dominance. Chloritisation and carbonation are the main alterations. There is a relationship between gold mineralisation at napélépéra and alteration, and the paragenesis of gold + pyrite ± carbonate ± silica ± sericite is the main characteristic. Carbonation is the result of fluid input in the shear corridor of the mineralised zone. The mass balance of comparative metals in the proximal and distal zones of the mineralisation shows the absence of metals, while As, Hg, Ag and Bi are strongly enriched from the distal zone to the mineralised zone. The oxides associated with the mineralisation are mainly naO, SrO and CaO.

The lamprophyres are late dykes that cut the formations hosting the gold mineralization in the nassara deposit. They are geographically and spatially related to most orogenic gold deposits. it is with the aim of characterizing them and seeing their implications for exploration that this work is carried out. To achieve our objective, petrographic studies and chemical analyses of minerals (pyroxenes, amphiboles, feldspars, chromite) and geochemical analyses of total rock were carried out. These studies have enabled us to classify the nassara lamprophyres as calc-alkaline lamprophyres of the spessartite type. The Cr, Co, ni and Mg enrichment of these rocks would indicate a depleted mantle source, with LiLE enrichment by fluids probably related to metasomatic activity. The various diagrams show that they are depleted in HREE and enriched in LREE. The high nb/ta ratios in our data indicate metasomatic activity probably linked to amphibole and rutile in the mantle prior to melting. The geodynamic context of spessartite-type lamprophyres indicates a signature linked to late-orogenic to post-collisional subduction. They are late-orogenic to post-collisional lamprophyres enriched in compatible elements (Cr, ni, Co) and display a negative ta-nb-Ti (TnT) anomaly. The frequent association of these lamprophyre dykes with the deposits does not indicate the source of the gold for these deposits, but rather zones of crustal permeability capable of draining hydrothermal fluids at the time of emplacement. Good mapping of lamprophyre dykes, especially in shear zones, could therefore guide prospecting and identify potential zones of hydrothermal fluid circulation.

Background: The emergence and spread of multidrug-resistant bacteria have become a major public health problem worldwide, particularly in developing countries such as Burkina faso. This study aims to determine phenotypic and genotypic antibiotic resistant diarrheagenic Escherichia coli (DEC) from patients with diarrhea in Ouagadougou, Burkina faso. Methodology: Microbiological and biochemical analysis were done to detect two hundred and ninety-two (292) strains. The susceptibility of the strains to antibiotics was determined by the agar disc diffusion method. 16-plex-PCR assays were carried out to detect both virulence and resistance genes encoding betalactams, quinolones, phenicols, tetracyclines and virulence gene of DEC. Results: Diarrheagenic Escherichia coli was detected in 8% (23/292) of patients with diarrhea using the 16-plex-PCR and 39.1% (9/23) of the DEC detected carry at least one resistance gene. Resistance rate in disc diffusion test was 86.96% to tetracycline, 65.23% to cotrimoxazole, 17.4% to nalidixic acid, 17.4% to norfloxacin, 17.4% to ciprofloxacin, 13.04% to ceftriaxone, 13.04% to cefotaxime, 8.7% to gentamicin, 8.7% to Chloramphenicol, 0% to netilmicin. The prevalence of different resistance genes in the studied strains varied from 44.4% to 5.5%. The gene Tet coding for resistance to tetracycline was found in 8 strains (44.4%). The Cata gene coding for resistance to Chloramphenicol was detected in 38.9% of isolates. The qnrS, blaSHV and blaOXA genes were each detected in 5.5% of isolates. no strain hosts the qnrA, qnrB and blaTEM genes. Conclusion: This study identified β-lactams, quinolones, phenicols and tetracyclines resistance genes in DEC isolates from patients with diarrhea in Ouagadougou, Burkina faso. These results indicate the need for a surveillance program to reduce the prevalence of resistance to Enterobacteriaceae strains in hospitals.

Tomato is a widely consumed vegetable in Burkina faso and throughout the world. However, when handled improperly, it can serve as a vector of pathogen transmission to human if ingested raw or through cross-contamination with cooked food. This study aimed to determine the prevalence of Salmonella spp from tomatoes sold in the markets of Ouagadougou, Burkina faso and characteristics of vending conditions. One hundred and ninety-eight (198) different tomato samples were randomly purchased from one hundred and thirteen (113) different vendors in the markets of Ouagadougou. The samples were examined and classified into three categories according to their texture and the level of deterioration. The prevalence of Salmonella spp identification was determined using standard microbiological methods. A survey was conducted using a questionnaire on transport and vending conditions for tomatoes. in total, Salmonella prevalence was 19.19% in all tomato’s samples analyzed and was 18.18% for intact category, 22.73% in D2 category and 16.67% in category D4. The survey revealed poor transport and sales conditions for the majority of tomato sellers. The present study revealed the presence of Salmonella in tomatoes samples. These results highlight the risk associated with the consumption of tomatoes if hygienic practices are not respected during tomatoes handling and preparation. The results of the study also show the need to wash tomatoes systematically after purchase with a disinfectant, especially tomatoes sold in open markets in developing countries.

introduction: Chronic renal failure is a real public health problem because of its prevalence, the cost of its management and the high morbidity and mortality rate associated with it. The objective of this study was to determine the frequency, causes and main aggravating factors of chronic renal failure in the medical department of the hospital of Sikasso. Materials and Methods: This was a cross-sectional, retrospective, descriptive study conducted in the medical department of the Sikasso hospital from January 1, 2021 to november 30, 2022. it covered all the records of patients with chronic renal failure hospitalized in the department during this period. The MDRD formula was used to estimate the glomerular filtration rate. The KDiGO 2012 classification was used to stage CKD. Results: Of 820 patient records reviewed, we retained 197 records. The mean age of our patients was 42.25 ± 10 years. The male sex represented 114 (57.9%). The socio-economic level was considered low and precarious in 79.8% of cases. The frequency of chronic renal failure was 24%. The reason for hospitalization was mostly hyper creatinine > 185 μmol/l (92.4%). Herbal medicine was reported in 103 cases (52.3%). Medical history was hypertension 101 cases (51.3%), undocumented gastro duodenal ulcer (UGD) 14 cases (7.6%), hypertension and diabetes 11 cases (5.1%), diabetes 8 cases (4%), lower limb edema 9 cases (4.6%). Hypocalcemia was 147 cases (75.6%) with hyper phosphoremia was 153 cases (77.7%). Hemoglobin level was: n 6 - 8 g/dl, 77 cases (39.1%), from 8 - 10 g/dl, 54 cases (27.4%). The etiologies of CKD were vascular nephropathy 106 cases (53.8%), interstitial nephropathy, 44 cases (22.3%), glomerular nephropathy, 33 cases (16.8%), diabetic nephropathy, 12 cases (6.1%) and polycystic kidney disease 2 (1%). CKD was classified as stage 5, 171 cases (86.8%), stage 4, 11 cases (5.6%), stage 3, 13 cases (6.6%) and stage 2, 2 cases (1%.) Dialysis was performed in 1095
