Documentation of gastrointestinal lesions in Brucella infections is sparse. A case of Brucella melitensis type 3 infection accompanied by erosive lesions of the colon, observed by endoscopy and histopathologic examination, is reported. Such gastrointestinal lesions have not been described since 1934. Before 1934 only postmortem observations are recorded.

Falsely elevated levels for haemoglobin A1 can be found with the haemoglobinopathies. A case is reported where falsely high levels for haemoglobin A1 were caused by the asymptomatic presence of haemoglobin K-Woolwich.
