The present invention relates to a recombinant protein comprising SEQ ID NO: 1 and a bacteria recognizing lectin. The present invention also relates to uses of the recombinant protein comprising detecting pathogens, removing endotoxins, determining the presence of an endotoxin or endotoxin-like material, and determining the presence of pathogen-associated molecular pattern (PAMP) comprising rhamnose-rhamnose (Rha-Rha), rhamnose-N-acetyl-mannosamine (Rha-ManNAc), N-acetyl-mannosamine-rhamnose (ManNAc-Rha), rhamnose-galatose (Rha-Gal), or galatose-rhamnose (Gal-Rha) in a sample, and use as a medicament, a disinfectant, a decontaminant, a surfactant or a diagnostic means. The present invention further relates to a method for prevention and/or treatment of conditions related to pathogen related infections in a patient in need thereof comprising: administering to said patient a pharmaceutically effective amount of composition comprising the recombinant protein, wherein the recombinant protein functions as an antagonist of PAMP comprising Rha-Rha, Rha-ManNAc, ManNAc-Rha, Rha-Gal, or Gal-Rha.
