Recurrent contamination of bacteriological specimens with Candida parapsilosis led to epidemiological investigations which indicated persistent colonization of carbon dioxide incubators as the most likely source. Changes in the technical arrangements and institution of a meticulous cleansing protocol eliminated contamination of specimens but not colonization of the incubators. Tests for tolerance of 17 % NaCl and survival at 50 °C, and SDS-PAGE analysis of crude cell extracts allowed discrimination between epidemic and non-epidemic isolates, while enzyme profile analysis and susceptibility studies failed as typing methods.

A case is reported of a male adult with Haemophilus influenzae type b septicaemia and subsequent abscess in the left thigh due to this microorganism following injection of phenylbutazone. The phenylbutazone probably caused muscle cell damage. It is assumed that Haemophilus influenzae type b colonized the site during an episode of septicaemia, with subsequent development of necrosis and abscess. [ABSTRACT FROM AUTHOR]

Although systemic infections with Pasteurella multocida rarely occur in humans, liver cirrhosis associated with septicemia due to this organism has been frequently reported. Two cases of elderly women with Pasteurella multocida septicemia are described who had diabetes mellitus and breast cancer, respectively. Underlying diseases other than liver cirrhosis as well as factors hitherto unknown in otherwise healthy persons also enhance the risk of Pasteurella multocida septicemia. [ABSTRACT FROM AUTHOR]
