We present here a fractional model in the sense of Caputo of a vector-borne disease with insecticide resistance genes. This study is important because it contributes to our understanding of vector-borne disease transmission dynamics using the notion of dif- ferential operators. The use of fractional derivatives in the model provides a memory efect and long-term dynamics often observed in infectious diseases. An epidemic must be able to decline slowly because of the memory of previous contacts. A detailed proof for the existence and uniqueness of the solution of the model is presented. The basic reproduction number R0 is derived, and a stability analysis of the equilibrium points is established. Numerical simulations are provided to prove the usefulness of the theoretical results. We simulated each model compartment at various fractional orders and compared them with integer-order simulat...

Passkeys are a passwordless authentication method that is increasingly being adopted. Based on asymmetric cryptography, they offer a secure and promising alternative to traditional passwords. In this paper, we propose a new secure approach for passkey synchronization based on a Peer-to-Peer mechanism between devices. Our secure services integrates biometric authentication via fingerprint or facial recognition, Wi-Fi Direct and QR codes. Also our secure approach use Elliptic Curve Diffie-Hellman algorithm for secure key exchange and Zero-Knowledge Proofs for mutual authentication in passkey system. This approach ensures the confidentiality and integrity of passkeys while eliminating reliance on central servers and strengthening protection against Man-in-the-Middle attacks and identity spoofing.

The increasing resistance of mosquito vectors to synthetic insecticides poses a major challenge to vector control and global public health, underscoring the urgent need for sustainable, environmentally safe alternatives. This study evaluated the larvicidal activity of aqueous, ethanolic, methanolic, and hydroethanolic extracts of Calotropis procera (Aiton) W.T.Aiton leaves against Aedes aegypti larvae. Significant variations in activity were observed across extraction solvent, ecological zone, and harvest season, with hydroethanolic extracts—particularly those collected in Kombissiri during the dry season—exhibiting the lowest LC50 values among the tested extracts (LC50 < 1600 ppm), indicating moderate larvicidal activity. Phytochemical profiling by high-performance thin-layer chromatography (HPTLC) revealed the presence of several classes of secondary metabolites, including flavonoids,...

Background: Antibiotic resistance is a growing concern in Burkina Faso, driven by widespread and inappropriate antimicrobial use. Methicillin-resistant Staphylococcus aureus (MRSA) poses a particular threat through community-acquired infections, which remain underreported. This study assessed MRSA prevalence and resistance patterns at the National Agency for Health Safety (ANSSEAT) in Ouagadougou. Methods: Forty-six S. aureus strains were isolated from vaginal swabs (39.97%), ear pus (34.42%), and urine samples (32.60%). Antibiotic susceptibility testing was performed using the disk diffusion method on Mueller-Hinton agar, following EUCAST-CA-SFM 2016 guidelines. Resistance rates included intermediate and resistant categories. Fisher’s exact test was used for comparative analysis. Results: Cefoxitin resistance indicated an MRSA prevalence of 8.71%. Oxacillin resistan...

Background Fish farming was introduced in Burkina Faso in the 1950s to offset declining capture fisheries and enhance food security. In Loumbila commune, aquaculture has recently expanded, but its growth is constrained by aquatic diseases. Biosecurity, essential for preventing pathogen introduction and spread, remains poorly implemented by local farmers, raising concerns for sustainability. Methods A cross-sectional survey was conducted among 23 purposively selected operators. Data were collected through questionnaires and direct observations, using KoBo Toolbox, and analyzed descriptively with Excel and SPSS version 25. Results The majority of respondents were women (52%), adults (78%), predominantly married (78%), and relatively inexperienced (65% with less than two years of practice). Although 78% had heard of biosecurity, only 11% could define it accurately...

This work concerns the design of a small hybrid photovoltaic/diesel generator power plant with battery energy storage. This system will supply electricity to the Koumnéré area, located in the South-Central region of Burkina Faso. Photovoltaic energy is obtained from a free primary energy source: solar energy. However, it is an intermittent energy source that depends on the time of day and is generally subject to weather conditions. Electricity production from diesel generators is stable, but the fuel it requires has a high cost. Furthermore, its operation is accompanied by greenhouse gas emissions. In addition, its efficiency remains average, estimated at around 45%. Therefore, we opted for a hybrid system, which offers several advantages. The energy needs assessment for the Koumnéré area was based on statistical data from the fifth General Population and Housing Census (GPHC) of Burkin...

Introduction: Emerging and re-emerging viral diseases are a growing threat to public health, especially in resource-limited countries. In Burkina Faso, the resurgence of dengue fever, associated with cases of chikungunya and measles, reflects persistent transmission and a morbidity and mortality still poorly documented in hospitals. The objective of this study was to describe the epidemiological profile of these diseases at the Yalgado Ouédraogo University Hospital Center in Ouagadougou. Methodology: It was a cross-sectional, descriptive and analytical study with retrospective data collection conducted from January 2018 to December 2023. All patients admitted to the infectious disease department for an emerging and re-emerged viral disease are included. Data was collected using the KoBoCollect application and analyzed with STATA v16 software. Results: A total of 464 patients (73.4%) out...

Spermophagus niger L. (Coleoptera: Chrysomelidae) is the main insect pest of Hibiscus sabdariffa seeds (Malvales: Malvaceae) during storage, with initial infestations occurring in the field. This study presents the first assessment of S. niger development on Hibiscus asper seeds (Malvales: Malvaceae), a wild and underutilized species widely distributed across tropical Africa and Madagascar. The aim was to evaluate its potential role in the ecological management of H. sabdariffa seed infestations. Twenty pairs of less than 24 h-old S. niger adults were individually placed in Petri dishes (9 cm diameter × 1.5 cm height), each in contact with 30 healthy H. asper seeds, under controlled conditions (32°C ± 0.1; 43 ± 1% r.h.) in total darkness. The seeds were renewed daily until the insects died. The results showed that S. niger completes its developmental cycle on H. asper seeds. However, its...

The preservation of agrobiodiversity is widely regarded as a cornerstone of sustainable agri-food systems, yet dominant narratives often portray crop diversity in smallholder farming as declining under pressures of intensification and market integration. Less attention has been given to how farmers themselves perceive, manage, and actively shape agrobiodiver sity over time. Drawing on political ecology and farmer-agency perspectives within a broader socio-ecological framework, this study examines patterns of crop species and varietal diversity across eight villages in Burkina Faso and Ghana. A mixed-methods approach combining surveys with 320 respondents and participatory focus group tools—including matrix scoring, four-square diagrams, and historical timelines—was used to analyze both quantitative trends in agrobiodiversity and farmers’ lived experiences. Results show that agrobiodiver...

Extended-spectrum β-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae are major contributors to antimicrobial resistance worldwide. Data from Burkina Faso remain limited, despite growing concerns about multidrug resistance in urinary pathogens. We conducted a retrospective cross-sectional study using microbiological records from three medical laboratories in Ouagadougou between January 2018 and December 2022. All urine culture isolates of E. coli and K. pneumoniae were included. Patient demographics, hospitalization status, and antimicrobial susceptibility profiles were extracted. ESBL production was confirmed phenotypically using the double disk synergy test. Statistical analyses were performed to compare prevalence and resistance patterns across species and patient groups. A total of 4,234 isolates were analyzed, comprising 3,084 E. coli (72.8%) and 1,...
