[A clinical study on patients detected Pasteurella multocida from sputum]

Outbreak of pasteurellosis in captive Bolivian squirrel monkeys (Saimiri boliviensis)

In September 2012, five Bolivian squirrel monkeys housed in a zoological park died within sequential several days without obvious clinical signs. In a necrospy, one monkey presented swelling of the kidney with multifocal white nodules in the parenchyma, and other two had pulmonary congestion. Histopathologically, multifocal bacterial colonies of gram-negative coccobacillus were found in the sinusoid of the liver in all monkeys examined (Nos.1−4). Additionally, purulent pyelonephritis, pneumonia and disseminated small bacterial colonies in blood vessels were observed. Immunohistochemically, the bacterial colonies from two monkeys were positive for P. multocida capsular serotype D. Based on these findings, these monkeys were diagnosed as septicemia caused by acute P. multocida infection.

Pasteurella haemolytica in Human Urine

Pasteurella haemolytica was isolated from a human urine specimen. This unusual human pathogen showed a mucoid colony with a modest haemolysis and typical biochemical characteristics. API 20E and API 20NE identified the bacterium as Pasteurella spp. and P. haemolytica, respectively. To the authors' knowledge, this is the first reported case of P. haemolytica in human urine.
