Abstract

The present invention is directed to a novel product and method for isolating ectoparasite saliva proteins, and a novel product and method for detecting and/or treating allergic dermatitis in an animal. The present invention includes a saliva protein collection apparatus capable of collecting ectoparasite saliva proteins substantially free of contaminating material. The present invention also relates to ectoparasite saliva proteins, nucleic acid molecules having sequences that encode such proteins, and antibodies raised against such proteins. The present invention also includes methods to obtain such proteins and to use such proteins to identify animals susceptible to or having allergic dermatitis. The present invention also includes therapeutic compositions comprising such proteins and their use to treat animals susceptible to or having allergic dermatitis.

Claims (9)

1. An isolated nucleic acid molecule comprising a nucleic acid sequence selected from the group consisting of:

(a) a nucleic acid sequence that encodes a protein comprising SEQ ID NO:6; and

(b) a nucleic acid sequence fully complementary to the nucleic acid sequence of (a).

2. The isolated nucleic acid molecule of claim 1 , wherein said nucleic acid sequence is selected from the group consisting of:

(a) a nucleic acid sequence that encodes a protein comprising SEQ ID NO:6, wherein the amino acid at position 10 of SEQ ID NO:6 is a cysteine, the amino acid at position 32 of SEQ ID NO:6 is a lysine, the amino acid at position 33 of SEQ ID NO:6 is isoleucine, the amino acid at position 36 of SEQ ID NO:6 is isoleucine and the amino acid at position 37 of SEQ ID NO:6 is cysteine; and

(b) a nucleic acid sequence fully complementary to the nucleic acid sequence of(a).

3. An isolated nucleic acid molecule comprising a nucleic acid sequence selected from the group consisting of:

(a) a nucleic acid sequence that encodes SEQ ID NO:25 or SEQ ID NO:26; and

(b) a nucleic acid sequence fully complementary to the nucleic acid sequence of (a).
