Background: Amylases, which are essential enzymes responsible for the breakdown of starch into glucose, serve pivotal functions across various industrial sectors, such as the food and pharmaceutical industries. This study focused on identifying amylase-producing bacteria from a soil sample collected at a cassava production site. Methods: Soil samples were subjected to serial dilution and cultured on starch agar plates to isolate potential amylase-producing bacteria. Nutrient agar was used as the...

Tetracyclines are broad-spectrum antibiotics that stop bacteria from producing proteins by blocking peptide elongation and aminoacyl-tRNA attachment, by reversibly binding to the 30S ribosomal subunit. Many tet genes, which are mobilized by integrons, transposons, and plasmids, encode tetracycline resistance mechanisms such as ribosome protection proteins (RPPs), efflux pumps, and enzymatic inactivation. These genes spread faster via mobile genetic elements, which allow for horizontal gene trans...

This study investigates the production of reuterin by Lactobacillus reuteri ATCC 53608, both in vitro and in situ in fermented milk products, and evaluates its antimicrobial activity against various microorganisms. Reuterin was synthesized in aqueous glycerol solution and within fermented milk, then tested against starter cultures ( Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus), spoilage organisms ( Penicillium expansum), pathogenic bacteria ( Staphy...

Biofertilizers present a viable solution for enhancing soil fertility, improving plant nutrition, and advancing environmental sustainability in agriculture and forest ecosystems. These microorganism-based fertilizers not only supply essential nutrients to plants but also foster soil health, thereby reducing reliance on synthetic fertilizers. This review highlights various types of biofertilizers, such as mycorrhizal fungi, rhizobia, and compost, and examines their mechanisms of action and applic...

Background: Infectious processes are the leading cause of pediatric consultation, and recurrent or severe infections may indicate primary immunodeficiencies (PIDs), which comprise more than 484 rare diseases affecting the immune response. The nature and severity of infections depend on the component of the immune system affected, with defects in humoral immunity being a frequent cause of severe respiratory infections. Evaluation of blood immunoglobulin (Ig) levels is essential for the identifica...

Access to clean and safe drinking water remains a major challenge in informal settlements such as Kibera in Nairobi, due to inadequate infrastructure, poor sanitation and reliance on unregulated water sources. This study assessed the prevalence of Escherichia coli (E. coli) contamination in water sources across 12 villages in Kibera and identified associated risk factors. A total of 72 water samples were collected and analyzed using the membrane filtration method. Overall, 29.2% of the samples w...

Introduction: Genital candidiasis is a common fungal infection primarily affecting women. It is caused by yeasts of the genus Candida, mainly Candida albicans. This infection can lead to symptoms such as itching, burning, vaginal discharge, and pain during sexual intercourse, thereby affecting the quality of life of patients. The study examines the prevalence of vaginal candidiasis among women consulting at the Mbangassina Hospital in Cameroon. It identifies as...
