Etiology-specific incidence and mortality of diarrheal diseases in the African region: a systematic review and meta-analysis.

Background: Diarrheal diseases substantially affect public health impact in low- and middle-income countries (LMIC), particularly in Africa, where previous studies have indicated a lack of comprehensive data. With a growing number of primary studies on enteric infections in Africa, this study aimed to estimate the incidence and mortality of diarrheal pathogens across all ages in Africa in the year 2020. We also explored different methodological assumptions to allow comparison with other approaches.

Molecular Characterization of Hetero-Pathogenic and Diarrheagenic Pathotypes in Diarrheic Children under Five Years and Exposure Environment in Ogun State, South-West Nigeria.

Background: Diarrheagenic (DEC) is one of the most common etiological agents of moderate-to-severe diarrhea in Low- and Middle-Income Countries (LMICs). Therefore, determining the source(s) of DEC in index cases and exposure environment is important for developing a prevention strategy. The current study aims to investigate the prevalence of DEC among children under 5 years and their exposure environment in Ogun State, Nigeria.

Prevalence, characterization and antibiotic resistance of Shiga toxigenic Escherichia coli serogroups isolated from fresh beef and locally processed ready-to-eat meat products in Lagos, Nigeria.

Fresh beef and meat products have been implicated in outbreaks of Shiga toxin-producing Escherichia coli (STEC) worldwide. This study investigated the prevalence of E. coli O157: H7 and non-O157 STEC serogroups in fresh beef in the open market and street vended meat products (n = 180) in Lagos metropolis, Nigeria.

Protein enrichment of an Opuntia ficus-indica cladode hydrolysate by cultivation of Candida utilis and Kluyveromyces marxianus.

Background: The cladodes of Opuntia ficus-indica (prickly pear cactus) have a low protein content; for use as a balanced feed, supplementation with other protein sources is therefore desirable. We investigated protein enrichment by cultivation of the yeasts Candida utilis and Kluyveromyces marxianus in an enzymatic hydrolysate of the cladode biomass.

Results: Dilute acid pretreatment and enzymatic hydrolysis of sun-dried cladodes resulted in a hydrolysate containing (per litre) 45.
