In this study, the characterisation of larval antigens by zymogram analysis of proteases indicated that digestive tract content (DTc) included different types of proteases more than salivary gland contents (SGc) and excretory secretory products (ESP). Proteases of DTc contain serine proteases, trypsin like proteases and chymotrypsin like serine proteases, while ESP and SGc contain mainly serine proteases. It was found that the presence of C. titillator larvae in camel, (Camelus dromedaries) resulted in a significant increase of NO production in camel mucus. The antibody titer in mucus samples of infested camels collected in winter using ELISA are higher than that collected in summer in both L2 and L3. In L2 the most antigenic secretion is SGc>ESP>DTc, but in L3 ESP> SGc> DTc. The antibody titer results in camel mucus are affected by the intensity of infestation with C. titillator
