Antibiotic sensitivity patterns of microbial isolates from fish ponds: A study in the Greater Accra Region of Ghana

Intensive use of antimicrobial agents in aquaculture provides a selective pressure creating reservoirs of drug-resistant bacteria and transferable resistance genes in fish pathogens and other bacteria in the aquatic environment. From these reservoirs, resistance genes may disseminate by horizontal gene transfer and reach human pathogens, or drug-resistant pathogens from the aquatic environment may reach humans directly....

Physicochemical characteristics and cytotoxic effect of the methanolic extract of Croton heliotropiifolius Kunth (Euphorbiaceae)

Croton heliotropiifolius Kunth is an endemic specie in northeast of Brazil. It is renowned for its medicinal properties, larvicidal and insecticidal actions. This work investigated the chemical compounds present in the methanolic extract of Croton heliotropiifolius and the cytotoxic activity. Physical-chemical analyses were performed by thin-layer chromatography (TLC), high-performance liquid chromatography (HPLC),...
