Method for the diagnosis of a worm infection, with which method DNA from the total DNA from the eggs of the nematode is amplified, in which method a DNA sequence comprising a species specific part of the 3' half of the beta -tubulin gene is used as primer or in which method two DNA sequences of parts of the beta -tubulin gene are used which parts are conserved in various nematodes as primers, which primers are located in the DNA sequence of the beta -tubulin gene in such a manner that the amplification product has species specific length per nematode. Preferably a method for the diagnosis of infection with H. contortus using a DNA sequence comprising a species specific part of the 3' half of the beta -tubulin gene of H. contortus as primer. The invention is also directed at a DNA sequence of a tubulin gene of Haemonchus contortus or a part thereof and preferably at a DNA sequence of the beta-tubulin gene of Haemonchus contortus or a part thereof. A method for the diagnosis of an infection with Haemonchus contortus, with which method the total DNA from the eggs of the nematode is applied to a (nylon) membrane and hybridised with a DNA probe being a sequence which comprises at least a part of one of the above mentioned sequences. |
