<i>In vitro</i> Antibacterial Activity of Crude Extracts from <i>Tithonia diversifolia</i> (Asteraceae) and <i>Solanum torvum</i> (Solanaceae) against Selected <i>Shigella</i> Species

Infectious diarrhea is a gastrointestinal illness that results in around 1.7 billion cases and 525,000 deaths annually, particularly among children under five, according to the World Health Organization. While some Cameroonian medicinal plants show promise for treating diarrhea, many plants are used without established scientific evidence of their efficacy. These plants include Tithonia diversifolia (T. diversifolia) and Solanum torvum (S. torvum), which are traditionally used to treat diarrheal symptoms. This study sought to investigate the anti-Shigella activity of leaf extracts from T. diversifolia and S. torvum.
