Bordetella pertussis agar media. This explained the difficulties in reproducing results from different studies, as the preinoculating handling of the bacteria were not standardized among scientists. At least some primate species are highly sensitive to "B. pertussis", and develop a clinical whooping cough in high incidence when exposed to low inoculation doses. Whether the bacteria spread naturally in wild animal populations is not satisfactory confirmed by laboratory diagnosis, but whooping cough has been found among wild gorillas. Several zoos have learned to vaccinate their primates against whooping cough. A nasopharyngeal or an oropharynx swab is sent to the bacteriology laboratory for Gram
Alexander disease the ability to talk. It also causes an overload of long-chain fatty acids in the brain, which destroy the myelin sheath. The cause of Alexander disease is a mutation in the gene encoding GFAP. A CT scan shows: Detecting the signs of Alexander disease is possible with magnetic resonance imaging (MRI), which looks for specific changes in the brain that may be tell-tale signs for the disease. It is even possible to detect adult-onset Alexander disease with MRI. Alexander disease may also be revealed by genetic testing for its known cause. A rough diagnosis may also be made through revealing
