Methanolic extracts from 15 medicinal plants representing 11 families, used traditionally for malaria treatment in Kenya were screened for their in vivo antimalarial activity in mice against a chloroquine (CQ)-tolerant Plasmodium berghei NK65, either alone or in combination with CQ. The plant parts used ranged from leaves (L), stem bark (SB), root bark (RB), seeds (S) and whole plant (W). When ...
The complement system plays a key role in host defense against pneumococcal infection. Three different pathways, the classical, alternative and lectin pathways, mediate complement activation. While there is limited information available on the roles of the classical and the alternative activation pathways of complement in fighting streptococcal infection, little is known about the role of the l...
Two force probing methods were used to quantify nanoscale forces in the interaction of bacterial lectin LecA with glycolipid Gb3, revealing how aids attachment and lowers energy required for uptake.
Cationic core/shell nanoparticles self-assembled from biodegradable, cationic and amphiphilic copolymer poly{N-methyldietheneamine sebacate)-co-[(cholesteryl oxocarbonylamido ethyl) methyl bis(ethylene) ammonium bromide] sebacate}, P(MDS-co-CES), were fabricated and employed to deliver lectin A-chain, an anticancer glycoprotein. Lectin A-chain was efficiently bound onto the surfaces of the nano...
Forty-six cultures of Listeria monocytogenes (including clinical, food and collection strains) were serotyped, characterized for motility, haemolysis and phospholipase activities and tested for lectin agglutination using a four-lectin set. Lectin reactivity (i.e. agglutination by one or more of the four lectins) was observed in all 12 clinical isolates, 16 of the 23 food isolates and eight of t...
Lectin induced in the hemolymph of Sarcophaga peregrina (flesh fly) larvae on injury of the body wall or on pupation was studied further by radioimmunoassay, focusing on the interaction between the lectin and hemocytes. It was found that the amount of lectin on the surface of hemocytes prepared from injured larvae increased with time after injury of the body wall. Radioiodinated lectin could bi...
A quantitative method was developed to measure the binding of fluorescent-labeled lentil (Lens esculenta Moench), pea (Pisum sativum L.), broad bean (Vicia faba L.), and jackbean (Canavalia ensiformis L., DC.) lectins to various Rhizobium strains. Lentil lectin bound to three of the five Rhizobium leguminosarum strains tested. The number of lentil lectin molecules bound per R. leguminosarum 128...
Embryos of the frog Xenopus laevis at cleavage, blastula, gastrula and neurula stages contain a galactose-specific lectin. Extracts of gastrula embryos show the highest specific activity for this lectin compared to the other stages. Haemagglutinating activity of crude extracts is inhibited by lactose, alpha-galactose, beta-galactose, alpha Gal(1----4) beta Gal, beta Gal(1----3) alpha GalNAc, be...
Water and reusable medical device surfaces can be contaminated by natural toxins such as ricin either accidentally or intentionally. This report focuses on the removal of peanut lectin (PL), a ricin surrogate, from water and reusable medical devices and materials. An ELISA assay was used to determine if commercially available water filters could remove peanut lectin from water, and if commercia...
