Molecular assays are uncommon in routine diagnosis of gastrointestinal bacterial pathogens in Burundi. This study aimed to characterize the diversity of bacterial pathogens among young children with diarrhea in selected healthcare settings and to demonstrate the efficiency of the AllplexTM GI-Bacteria (I) assay over the conventional culture. Methods We conducted a cross-sectional study in seven (7) selected health districts in Burundi. We used a questionnaire to collect sociodemographic information for children ≥ 5 years old whose parents consented to participate. We collected stool samples for both conventional cultures (gold standard) and AllplexTM GI assay. We plated the stool samples shortly after collection and we kept the samples in the fridge between 4–8 ℃ for less than 24 hours before we processed them with the AllplexTM GI kit. We determined the association between s...

The aimed was to evaluate the hepato-curative activity of lyophilized aqueous decoction (LAD) and hydroethanolic macerate (LHM) of plant extracts on CCl4-induced hepatitis in rats. We assessed the acute toxicity and scavenging activity of the 2, 2-Diphenyl-1-picrylhydrazyl (DPPH). Hepato-curative activity study included nine groups with five rats each. We used rats as followed: group 1 as neutral controls, group 2 as negative controls, and the other groups were experimental groups. Rats in groups 2-9 received a single dose (1 mL/kg) of CCl4 in intraperitoneal injection to induce hepatitis. We fed orally the rats for seven consecutive days with sylimarin in group 3, LAD and LHM respectively in groups 4-6 and groups 7-9 by 400, 200 and 100 mg/kg/day. This study revealed LAD and LHM had a LD50> 2000 mg/kg a...

Recent advances in next-generation sequencing (NGS) technologies provide new and effective ways of tracking drug-resistant malaria parasites in Africa. The diversity and the prevalence of Plasmodium falciparum drug-resistance molecular markers were assessed in Dangassa and Nioro-du-Sahel in Mali, two sites with distinct malaria transmission patterns. Dangassa has an intense seasonal malaria transmission, whereas Nioro-du-Sahel has an unstable and short seasonal malaria transmission. Methods Up to 270 dried blood spot samples (214 in Dangassa and 56 in Nioro-du-Sahel) were collected from P. falciparum positive patients in 2016. Samples were analysed on the Agena MassARRAY® iPLEX platform. Specific codons were targeted in Pfcrt, Pfmdr1, Pfdhfr, and Pfdhps, Pfarps10, Pfferredoxin, Pfexonuclease and Pfmdr2 genes. The Sanger’s 101-SNPs-barcode method was used to assess the genetic diversity...

This study aimed to describe the characteristics of scholarly journals expected to publish articles on public health from a number of African countries. Using African Journals Online and African Index Medicus, 174 journals from 13 African countries were identified. The six countries above the group’s median gross domestic product (GDP) published 145 journals, while the seven countries at or below the median GDP published 29 journals. Two thirds of the journals were freely available to download, but only a third had a Creative Commons licence, and most were not indexed. Around half of the journals levied full article processing charges (APCs) – journals from countries at median GDP or below were less likely to charge APCs than those from countries above the median GDP. One of the key findings is that only a few journals were indexed, limiting the ability of potential readers to find the results of research performed in local settings. The results suggest a need to assist journals and researchers to make the work they publish more accessible to the audience who might want to use the results.

Over the years, the lengthening of surgical procedures in human surgery and the increasingly frequent use of inert material has increased the risk of infections. This was why skin antisepsis has become very important in the prevention of infections of the surgical wound and resulting complications. In Mali, at the Gabriel Touré University Hospital, the most prescribed family of antiseptics was the halogenated ones, in particular 10% povidone iodine for wound and surgical site antisepsis. This study was aimed to control the quality of 10% povidone iodine used in the hospital. Methodology: We conducted at the Medicines Quality Control Service of the National Health Laboratory of Mali (LNS) a retrospective analytical study on the quality control of 10% povidone iodine. We obtained 10% povidone iodine samples from the Pharmacie Populaire du Mali (PPM). We analyzed 48 batches of samples in regards o...

Since the introduction of ACT, few reports are available on the level of resistance of Plasmodium falciparum (P. falciparum) to antimalarial drugs in Mali. Dihydroartermisinin is the active metabolite of artemisinin derivatives. Here, we conducted an ex-vivo drug sensitivity testing in a rural area of southern Mali, namely the Kéniéroba village from 2016 to 2017. Methods: Seventy-five (75) isolates of P. falciparum were successfully evaluated for ex-vivo sensitivity to key anti-malarial drugs, namely chloroquine (CQ), quinine (QN), amodiaquine (AQ), mefloquine (MQ), lumefantrine (LUM), dihydroartermisinin (DHA) , and piperaquine (PPQ). P. falciparum sensitivity to these drugs was assessed using the World Wide Antimalarial Resistance Network (WWARN) SYBR-GREEN method of inhibitory concentration of 50% (...

This exclusion mainly affects people living in rural areas, who are nevertheless the most susceptible to diseases. The Medical Assistance Plan allows a marked improvement in access to healthcare by poor patients. It eliminates out of pocket healthcare cost, which normally prevents most of them from accessing health care. Materials and methods: This study was aimed to investigate the accessibility to healthcare for poor patients at the University Hospital Point G. We conducted a 12-month descriptive cross-sectional study from March 2018 to April 2019. Data entry and analysis were performed using SPSS version 21.0. Results: Our study participants we interviewed were aged 30-44 years old in 30.7%, female in 60.7%, and housewives in 46.7%. Our interviewees consulted for consulted for chronic diseases in 79.3%, had no monthly income in 78.7% and obtained the healthcare benefits at no cost to...

The main mechanisms of malaria involve the synergistic interactions between host and parasite. Although, the role of the spleen has been mentioned in various clinical forms of malaria, a supportive clinical evidence is still needed. We conducted a pilot study to determine the impact of the spleen functional state in different clinical forms of malaria.Ex vivo microsphiltration was used to assess the splenic function in patients received during routine consultation with malaria at the Kéniéroba health center, a high malaria endemic area in Mali.A total of 25 patients were enrolled for microsphiltration. Two patients (8%) had a no palpable spleen (Hackett stage 0), 22 patients (88%) had a palpable spleen with at deep inspiration (Hackett stage 1) and only one patient (4%) presented a palpable spleen (Hackett stage 2). Parasitaemia ranged from 5360 trophozoites/µl to 342720 trophozoites/µl with a mean parasitemia of 50774 trophoz...

To succeed, the Malian has developed NMCP guidelines for the management of malaria cases in pregnant women. The study aimed at the analysis of the prescription of antimalarial drugs based on the Mali's NMCP guidelines. We conducted a cross-sectional study during malaria transmission season from June to August 2020. The sampling concerned all prescriptions for pregnant women containing at least one antimalarial drug. The frequency of prescription of antimalarial drugs was 85%. 132 (74.16%) were preventive treatments and 46 (25.84%) curative treatments. 30 (90.91%) of pregnant women in the first trimester received one dose of Sulfadoxine-Pyrimethamine. 6 (12.5%) received three doses in the third trimester. Of the 46 antimalarial drugs prescribed for the treatment of uncomplicated malaria, 30 (65.22%) were Artemether-lumefantrin...
