Soil salinization is one of the major causes of land degradation. In Senegal, this phenomenon continues to grow, making soils unsuitable for agriculture. To rehabilitate salty lands, one of the recommended strategies is the use of salt-tolerant plants. Among them, plants of Casuarinaceae family form a relationship with symbiotic microorganisms such as arbuscular mycorrhizal fungi and nitrogen fixing bacteria. It has been shown that symbiotic microorganisms play an important role in the establishment of tolerant plants in saline conditions (Djighaly et al., 2018). They improve plant performance and reduce transplant shock under salt stress conditions (Diagne et al., 2014). These microorganisms can be used as biofertilizers. However, inocula containing symbiotic microorganisms are either too expensive or unavailable in many developing countries. The aim of this study is to test alternatively affordable and low-tech solutions to promote symbiotic interactions such as Casuarina crushed nodule, Casuarina rhizosphere soil and Casuarina leaves compost that may contain symbiotic microorganisms and also nutrients such as N and phosphorus. Two species of Casuarina (Casuarina equisetifolia L. and Casuarina obesa Miq.) were grown in the greenhouse on sterile soil to which an amendment was added (Casuarina crushed nodules, Casuarina Rhizospheric soil or Casuarina leaves compost). Plants were subjected to saline stress. After four months of cult

Introduction: Tetanus portals of entry are numerous. Amongst these, the carerelated portals of entry are rarely reported. The aim of the study was to describe the epidemiological, clinical and outcome aspects and identify the factors associated with death from care-related tetanus. Patients and Methods: This is a retrospective study of descriptive and analytical purposes. Data were collected from the medical records of patients admitted to the Infectious and Tropical Diseases Department of the National University Hospital Center (CHNU) of Fann in Dakar for care-related tetanus during the period ranging from 1 January 2009 to 31 December 2016. Care-related tetanus was defined as any case of tetanus occurring after a surgical procedure, including circumcisions performed even outside a health facility. Results: In eight years, 50 cases of care-related tetanus were recorded. Care-related tetanus accounted for 6.7% of hospitalized tetanus cases. The mean age of patients was 21 ± 22 years, with a male predominance (sex ratio: 6.14). The procedure had been performed in most cases, either in a health facility in 22 patients (44%) or at home in 16 patients (32%), and occurred after circumcision. In 62% of cases the portal of entry was urological, followed by orthopedic surgery (14%) and visceral surgery (10%). The procedures performed were dominated by circumcision (31 cases), limb amputation (3 cases) and inguinal hernia repair (2 cases). Tetanus was immediately generalized on admission in all patients. Eighty-four percent (84%) of patients were admitted with Mollaret stage II. Cardiovascular (11 cases), infectious (10 cases) and respiratory (9 cases) complications were the most frequent. The hospital case fatality rate was 24%. Factors associated with death were female gender (p = 0.03), age between 15 - 60 years (p = 0.02), incubation time Conclusion: Care-related tetanus remains a concern in poor income countries, particularly in Senegal. The drop of these cases will req
