Hookworm infection is a major concern in sub-Saharan Africa, particularly children and pregnant women. Necator americanus Ancylostoma duodenale are responsible for this condition. disease one of the Neglected tropical diseases (NTDs) that targeted elimination through global mass chemotherapy. To support there need reliable diagnostic tools. The conventional test, Kato-Katz based on microscopic detection parasite ova faecal samples, not effective due to its low sensitivity brought about...

Common rust (CR) caused by Puccina sorghi is one of the destructive fungal foliar diseases maize and has been reported to cause moderate high yield losses. Providing CR resistant germplasm potential increase yields. To dissect genetic architecture resistance in maize, association mapping, conjunction with linkage joint mapping (JLAM), genomic prediction (GP) was conducted on an association-mapping panel five F3 biparental populations using genotyping-by-sequencing (GBS) single-nucleotide...

Proteus spp ., Staphylococcus Pseudeomonas and pathogenic Vibrios are among the major foodborne pathogens associated with consumption of contaminated fish. The increasing occurrence antimicrobial resistance in these is a serious public health concern globally therefore continuous monitoring bacteria along food chain crucial for control illnesses. aim this study was to assess prevalence, patterns, antibiotic genes, genetic diversity bacterial recovered from fresh Nile tilapia ( Oreochromis...

Abstract The black soldier fly (BSF), Hermetia illucens , has garnered significant attention recently due to its potential applications in waste management, animal feed production, frass fertilizer and biotechnology. Despite numerous advantages, genomic resources for BSF remain limited, underscoring the necessity continued exploration. This review provides a comprehensive overview of landscape BSF, emphasizing critical role genomics understanding biology optimizing applications. We...

Anti-malarial drugs are the major focus in prevention and treatment of malaria. Artemisinin-based combination therapy (ACT) is WHO recommended first-line for Plasmodium falciparum malaria across endemic world. Also ACT increasingly relied upon treating vivax where chloroquine failing. The emergence artemisinin drug-resistant parasites a serious threat faced by global control programmes. Therefore, success intervention strategies highly pegged on understanding genetic basis resistance. Here,...

The invasion of human erythrocytes by Plasmodium falciparum merozoites requires interaction between parasite ligands and host receptors. Interaction Pf Rh5-CyRPA-Ripr protein complex with basigin, an erythrocyte surface receptor, via PfRh5 is essential for invasion. Antibodies raised against each antigen component the have demonstrated inhibition, making these proteins potential blood-stage vaccine candidates. Genetic polymorphisms present a significant challenge in developing efficacious...

Kenyans have long utilized Ocimum kilimandscharicum, an East African permanent evergreen plant, to treat measles, stomachaches, diarrhea, mosquito bites (anti-insect), congested chest, cough, and colds. Using conventional qualitative quantitative techniques, this study was done identify the secondary metabolites in O. kilimandscharicum leaf extracts. The chemical content of crude extracts from leaves has also been investigated characterized using gas chromatography-mass spectrometry (GC-MS)....

Entamoeba histolytica, the causative agent for amoebiasis is a considerable burden to population in developing countries where it accounts over 50 million infections. The tools detection of are inadequate and diagnosis relies on microscopy which means significant percent cases remain undiagnosed. Moreover, tests formats that can be rapidly applied rural endemic areas not available. In this study, loop-mediated isothermal test (LAMP) based 18S small subunit ribosomal RNA gene was designed...

Background. Cryptosporidium is a protozoan parasite and major cause of diarrhea in children immunocompromised patients. Current diagnostic methods for cryptosporidiosis such as microscopy have low sensitivity while techniques PCR indicate higher levels but are seldom used developing countries due to their associated cost. A loop-mediated isothermal amplification (LAMP) technique, method with shorter time result equal or compared PCR, has been developed applied the detection species. The test...

Nitrogen is the most limiting nutrient for growth of crop plants in sub-Saharan Africa and legume crops largely depend on fixed nitrogen from indigenous nitrogen-fixing bacteria. The identification symbiotic characterization rhizobia basis inoculants formulation sustainable production face climate change. aim this study was to evaluate diversity responsible cowpea nodulation farmers' fields across three Counties Western Kenya. performance abiotic stress-tolerant their homologous also...

Unreliability of the data streams generated by RFID readers is among primary factors which limit widespread adoption technology. cleaning is, therefore, an essential task in middleware systems order to reduce reading errors, and allow these be used make a correct interpretation analysis physical world they are representing. In this paper we propose adaptive sliding-window based approach called WSTD capable efficiently coping with both environmental variation tag dynamics. Our experimental...

Radio frequency identification (RFID) technology enables information to be remotely stored and retrieved by means of electromagnetic radiation. Compared other automatic technologies, RFID provides an efficient, flexible inexpensive way identifying tracking objects. Asset management is one the potential applications for technology. using reduces workload on asset audit administrators while eliminating error prone manual processes. Successful implementation system requires intelligent use data...

Background: Livestock are key sources of livelihood among pastoral communities. productivity is chiefly constrained by pests and diseases. Due to inadequate disease surveillance in northern Kenya, little known about pathogens circulating within livestock the role livestock-associated biting keds (genus Hippobosca) transmission. We aimed identify prevalence selected hemopathogens their associated blood-feeding keds. Methods: randomly collected 389 blood samples from goats (245), sheep (108),...
