The culture medium of claim 1, wherein the culture medium further comprises, simple sugars, lipids, and minerals to support the growth of the fastidious microorganism. 5. The culture medium of claim 1, wherein the culture medium comprises cobalt and molybdenum. 6. The culture medium of claim 1, wherein the culture medium does not contain simple sugars. 7. The culture medium of claim 1, wherein the culture medium comprises sucrose, maltose and glucose. 8. The culture medium of claim 1, wherein the culture medium comprises lipids. 9. The culture medium of claim 8, wherein the culture medium comprises lipids that are found in mammalian brain tissue. 10. The culture medium of claim 1, wherein the culture medium comprises NAD and NADP. 11. The culture medium of claim 1, wherein the culture medium comprises sufficient anti-oxidants and reducing agents to support the growth of a fastidious microorganism. 12. A method of culturing a fastidious microorganism comprising culturing a sample containing a fastidious microorganism in a culture medium according to claim 1 for a time and under conditions sufficient to grow a fastidious microorganism present in the sample. 13. The method of claim 12, wherein the fastidious microorganism is a cell wall deficient microorganism. 14. The method of claim 12, wherein the fastidious microorganism is a stressed microorganism. 15. The method of claim 12, wherein the fastidious microorganism is an immunologically impaired microorganism. 16. The method of claim 12, wherein the fastidious microorganism has metabolic defects. 17. The method of claim 12, wherein the fastidious microorganism has defects in nutrient transport. 18. The method of claim 12, wherein the fastidious microorganism is a viable but nonculturable microorganism. 19. The method of claim 12, wherein the culture medium further comprises, simple sugars, lipids, and minerals to support the growth of the fastidious microorganism. 20. The method of claim 12, further comprising passing the sample through one or more filters prior to culturing the sample in the culture medium. 21. The method of claim 12, wherein the sample is cultured in the culture medium for a period of 24 to 72 hours. 22. The method of claim 12, wherein the sample is cultured in the culture medium for a period of two to four weeks. 23. The method of claim 12, wherein the fastidious microorganism is an insect-borne or arachnid-borne microorganism. 24. The method of claim 12, wherein the fastidious microorganism is a mammalian pathogen. 25. The method of claim 24, wherein the mammalian pathogen is pathogenic in a mammal selected from the group consisting of canines, felines, bovines, caprines, equines, ovines, porcines, rodents, lagomorphs, and primates. 26. The method of claim 24, wherein the mammalian pathogen is associated with a condition selected from the group consisting of chronic fatigue syndrome, cancer, hypertension, heart disease, cystic fibrosis, cat scratch disease, renal disease, liver disease, prostate disease, central nervous system disorders, urologic disorders, hyperadrenalcorticism, mastitis, polyarthritis, immune-mediated hemolytic anemia and thrombocytopenia. 27. The method of claim 12, wherein the sample is a biological sample from a mammalian subject. 28. The method of claim 27, wherein the biological sample is a body fluid sample. 29. The method of claim 28, wherein the body fluid sample is selected from the group consisting of blood, plasma, serum, urine, cerebrospinal fluid, pleural fluid, pulmonary mucus, sputum, transudates, modified transudates, exudates, chest fluid, abdominal fluid, synovial fluid, peritoneal fluid, lymph, and effusions. 30. The method of claim 12, wherein the sample is an insect or arachnid sample. 31. The method of claim 12, wherein the sample is a blood product sample. 32. The method of claim 12, wherein the culture medium is a liquid culture medium. 33. The method of claim 12, wherein the culture medium is a solid medium. 34. The method of claim 12, wherein the fastidious microorganism is a bacterium. 35. The method of claim 34, wherein the bacterium is a Proteobacterium. 36. The method of claim 34, wherein the bacterium is selected from the group consisting of Bartonella, Rasbo bacterium, Burcella, Afipa, Burkholdrea pickettli, Streptococcus thermophillis, and Corynebacterium. 37. The method of claim 34, wherein the bacterium is a nanobacterium. 38. The method of claim 34, wherein the bacterium does not have a cell wall. 39. A method of detecting a fastidious microorganism in a sample comprising: culturing a sample containing a fastidious microorganism in a culture medium according to claim 1 for a time and under conditions sufficient to grow the fastidious microorganism; and detecting the fastidious microorganism. 40. A method of identifying a fastidious microorganism in a sample, comprising: culturing a sample containing a fastidious microorganism in a culture medium according to claim 1 for a time and under conditions sufficient to grow the fastidious microorganism; and identifying the fastidious microorganism. 41. A method of identifying a compound that binds to a fastidious microorganism, comprising: culturing a sample containing a fastidious microorganism in a culture medium according to claim 1 for a time and under conditions sufficient to grow the fastidious microorganism; contacting the fastidious microorganism with a compound; and detecting binding between the fastidious microorganism and the compound. 42. The method of claim 41, wherein the compound is an antibody. 43. The method of claim 41, wherein the compound reduces the growth or viability of the fastidious microorganism. 44. A method of diagnosing a mammalian subject with an infection by a fastidious microorganism, comprising: culturing a sample from a mammalian subject containing a fastidious microorganism in a culture medium according to claim 1 for a time and under conditions sufficient to grow the fastidious microorganism; identifying the fastidious microorganism in the cultured sample; and diagnosing the subject as having an infection with the fastidious microorganism. 45. A method of diagnosing a disorder in a subject comprising: culturing a sample containing a fastidious microorganism in a from a subject culture medium according to claim 1 for a time and under conditions sufficient to grow the fastidious microorganism; and identifying the fastidious microorganism in the cultured sample; wherein the presence of the fastidious microorganism in the sample is associated with the disorder. 46. A method of culturing a nanobacterium comprising culturing a sample comprising the nanobacterium in a culture medium according to claim 1 for a time and under conditions sufficient to grow the nanobacterium. 47. A method of culturing Corynebacteria, comprising culturing a sample containing Corynebacteria in a culture medium according to claim 1 for a time and under conditions sufficient to grow Corynebacteria present in the sample.
