A case of subacute bacterial endocarditis in which Cardiobacterium hominis was isolated from the blood of a 55-year old woman who had rheumatic heart disease is reported. A survey of the literature revealed very few reports in which this organism has been implicated in human lesions. The colonies grew after 48 hours of incubation in a candle jar. They were small, convex, nonhemolytic, and oxidase-positive. The indole reaction was positive, the catalase and nitrate reactions were negative, and acid reaction was obtained from the following carbohydrates: glucose, maltose, mannitol, sucrose, and sorbitol. The morphologic and biochemical properties served to distinguish these organisms from similar bacteria implicated in human disease, such as Haemophilus aphrophilus, Actinobacillus actinomycetemcomitans, Streptobacillus moniliformis, and HB-1.

In a five-year prospective study of blood culture-positive septicaemia in a Hong Kong teaching hospital there were 2211 clinically-significant episodes, of which 16% occurred in children less than 15 years old. The microbiology and clinical features were broadly similar to those seen in Europe and North America, but with some important differences. Two-thirds of episodes were community-acquired. The most common organism isolated from community-acquired septicaemias was Escherichia coli and the source, most commonly, the urinary tract. However, the biliary tract was the second most common source of community-acquired infection (25%), reflecting the frequency of liver disease in Hong Kong. Three per cent of community-acquired septicaemias were associated with endocarditis; half of these were with viridans streptococci, usually in patients with rheumatic heart disease, and 40% were in drug addicts with methicillin-sensitive Staphylococcus aureus. The commonest organisms causing community-acquired childhood infections were Salmonella spp. (27%) and Streptococcus pneumoniae (22%), whereas pneumococci accounted for only 3% of adult community-acquired micro-organisms. Haemophilus influenzae infections were uncommon and there was no case of meningococcal or gonococcal septicaemia. The commonest cause of hospital-acquired septicaemia was Staph. aureus (24%), of which 46% were methicillin-resistant. The characteristics of septicaemia in Hong Kong are influenced by the patient population structure, endemic disease patterns, local medical practice and socio-economic factors, but the rarity of Str. pneumoniae in adults and of H. influenzae and Neisseria meningitidis in children is unexplained.
