Screening of bacterial isolates for mannose-specific lectin activity by agglutination of yeasts

Screening of bacterial isolates for mannose-specific lectin activity by agglutination of yeasts.

A total of 393 clinical bacterial isolates were tested for their ability to agglutinate yeast cells of either Saccharomyces cerevisiae or Candida albicans. A positive agglutination of yeasts that could be prevented by methyl alpha-D-mannoside was taken as an indication for the possible presence of a mannose-specific lectin (carbohydrate-binding protein) on the surface of the tested bacteria. Ag...

Bacterial Agglutination by Sialic Acid-Specific Lectin in the Hemolymph of the Banana Shrimp, Penaeus (Fenneropenaeus) merguiensis

A lectin from the hemolymph of the banana shrimp Penaeus (Fenneropenaeus) merguiensis expressed higher agglutination activity against rabbit erythrocytes than those from human, and its activity was Cadependent. The hemagglutinating activity of the hemolymph lectin was stable up to 55 C and optimal at pH 7.5-8.0. N-acetylated sugars, ManNAc, GlcNAc, GalNAc, and NeuNAc, were effective inhibitors ...

Bacteria despite MBL Binding Opsonophagocytosis of Yeasts but Not of Mannose-Binding Lectin (MBL) Facilitates

High Bacterial Agglutination Activity in a Single-CRD C-Type Lectin from Spodoptera exigua (Lepidoptera: Noctuidae)

Lectins are carbohydrate-interacting proteins that play a pivotal role in multiple physiological and developmental aspects of all organisms. They can specifically interact with different bacterial and viral pathogens through carbohydrate-recognition domains (CRD). In addition, lectins are also of biotechnological interest because of their potential use as biosensors for capturing and identifyin...
