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
Fatty liver disease Fatty liver disease Fatty liver disease (FLD), also known as hepatic steatosis, is a condition where excess fat builds up in the liver. There are two types non-alcoholic fatty liver disease (NAFLD) and alcoholic liver disease. NAFLD is made up of simple fatty liver and non-alcoholic steatohepatitis (NASH). Risk factors for NAFLD include diabetes, obesity, and older age. The condition is also associated with other diseases that influence fat metabolism. It is difficult to distinguish alcoholic FLD, which is part of alcoholic liver disease, from nonalcoholic FLD (NAFLD), and both show microvesicular and macrovesicular fatty changes at different stages.
