Two strains of Escherichia coli that formed on unusual kind of mannose‐resistant and eluting haemagglutinin (MREHA) reacting with the red blood cells of rat and mouse, when cultured at 37°C but not at 18°C, were examined by electron microscopy. Production of this rare rodent‐positive MREHA was correlated with the presence of fine fibrillae of estimated diameter 2.5 nm that were demonstrated by negative staining and immuno‐gold labelling with MREHA‐specific antiserum. These two strains belonged to serotypes 078:H − and 078:H33; thus, it would be useful to know whether enteroadherent‐aggregative strains of E. coli of these and other serotypes also possess this unusual MREHA.
