The method according to claim 1, wherein the infection being detected is mastitis, the animal is a mammal and the selected anatomical structure is a mammary gland. 9. The method according to claim 8, comprising the steps of: (a) obtaining one or a plurality of infrared thermographic images of the mammary gland of the mammal, wherein the one or a plurality of infrared thermographic images provide the measure of the temperature information representative of the mammary gland; (b) comparing the measure of the temperature information representative of the mammary gland to the predetermined value; and (c) detecting the presence of mastitis in the mammal if the measure of the temperature information is greater than the predetermined value by the predetermined amount. 10. The method according to claim 9, wherein the predetermined value is selected from the group consisting of: (i) the measure of the temperature information of the mammary gland of the same mammal unaffected by mastitis; and (ii) the measure of the temperature information of the mammary gland of a population representative of the mammal, wherein the population comprises mammals unaffected by mastitis. 11. The method according to claim 10, wherein the measure of the temperature information is a measure of central tendency. 12. The method according to claim 11, wherein the measure of central tendency is a mean. 13. The method according to claim 12, wherein the predetermined amount is at least 0.1째 C. 14. The method according to claim 12, wherein the predetermined amount is greater than 0.5째 C. 15. The method according to claim 12, wherein the predetermined amount is greater than 1째 C. 16. The method according to claim 10, wherein the plurality of images are obtained successively over time to identify the mammal as having mastitis if the change over time of the measure of the temperature information provided by the plurality of images is greater than a predetermined rate. 17. The method according to claim 16, wherein said predetermined rate is 0.1째 C. per hour. 18. The method according to claim 10, wherein the mammal is a non-human mammal. 19. The method according to claim 10, wherein the mammal is selected from a cow, pig, horse, dog or cat. 20. The method according to claim 10, wherein the mammal is of the species Bos taurus or Bos indicus. 21. The method according to claim 20, wherein the mammary gland is an udder. 22. The method according to claim 21, wherein a first image is obtained of one quarter of the udder at time 0 and a second image is obtained of the same quarter of the udder at a later time. 23. The method according to claim 22, wherein a total temperature of the first image and a total temperature of the second image are determined. 24. The method according to claim 23, wherein mastitis is detected if the total temperature of the first image differs from the total temperature of the second image by greater than the predetermined amount. 25. The method according to claim 24, wherein the total temperature of the first image is determined by multiplying the area represented by the first image by the mean of the temperature information provided by the first image, and the total temperature of the second image is determined by multiplying the area represented by the second image by the mean of the temperature information provided by the second image. 26. The method according to claim 25, wherein the predetermined amount is 10%. 27. The method according to claim 24, wherein the mammal is a non-human mammal. 28.
