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
Ménétrier's disease Ménétrier's disease Ménétrier disease (also known as hypoproteinemic hypertrophic gastropathy; named after a French physician Pierre Eugène Ménétrier, 1859–1935), is a rare, acquired, premalignant disease of the stomach characterized by massive gastric folds, excessive mucous production with resultant protein loss, and little or no acid production. The disorder is associated with excessive secretion of transforming growth factor alpha (TGF-α). Individuals with the disease present with upper abdominal pain (epigastric), at times accompanied by nausea, vomiting, loss of appetite, edema, weakness, and weight loss. A small amount of gastrointestinal bleeding may occur, which is typically due to superficial mucosal erosions; large
