The objective of the study was to identify accessions of T. tuberosum with highest quantities of thiocyanates, starches and sugars. The study was performed in Cevallos, Ecuador. Six accessions were cultivated in six individual plots and processed. The Yellow, White and Purple accessions were exposed to sunlight for periods of 3, 6 and 9 days. The resulting biomass was analysed: The Purple variety presented the greatest quantity of thiocyanates (663 mg/100g) after three days' exposure. Meanwhile, the Yellow variety showed the highest amount of starches (47%) and total sugars in freshly-harvesting. The results reveal the potential of these accessions as a source of starch and thiocyanate. [ABSTRACT FROM AUTHOR]

Foodborne pathogens represent a significant cause of negative impacts on human health and the economy worldwide. Unfortunately, information about epidemiological insights in Latin American countries is scarce. The consumption of ready-to-eat street food in Ecuador is extensive, and information about the presence of foodborne pathogens, their virulence factors, and antimicrobial resistance is negligible. This data includes the occurrence, phenotypic antibiotic resistance profiles, and antibiotic resistance genes of Enterobacterales isolated from ready-to-eat street food in Ambato, central Ecuador during 2020 and 2021. The most common genera detected were Escherichia coli , Klebsiella spp. , and Cronobacter spp . Agar disk diffusion assays were performed to determine their phenotypic resistance. The presence of antibiotic resistance genes conferring resistance against colistin, β-Lactams, aminoglycosides, tetracyclines, sulfonamides, fluoroquinolones, and amphenicols was detected via polymerase chain reaction (PCR) amplification., Competing Interests: No competing interests were disclosed., (Copyright: © 2022 Tubón J et al.)

Background: Given the considerable role played by Salmonella in the incidence of food poisoning around the world, surveillance of this infection is prioritized by both food producers and health care authorities. Data remains insufficient concerning the prevalence of Salmonella in poultry systems in Ecuador and in Latin America in general. Methods: In this study we evaluated the prevalence and diversity of Salmonella serovars in samples taken from 21 layer farms and backyard layers in central Ecuador during August-November 2017.   Salmonella was isolated following standardized methods (ISO 6579) and the serovar determination was carried out by PCR. Results: A significant presence of Salmonella was detected, with an incidence of 76% (95% confidence interval (CI): 58-94) in farms, 33% (95%CI: 13-53) in pooled cloacal swabs from layer hens, 33% (95%CI: 12-55) on feed samples, and 10% (95%CI: 0-22) in backyard layer feces from traditional local markets. The dominant serovars detected were S. Infantis and S. Typhimurium. Conclusions: This study forms a basis for further surveillance of Salmonella serovars in layer farms in central Ecuador., Competing Interests: No competing interests were disclosed.
