Echocardiographic Findings

Aerococcus viridansis an infrequent human pathogen and few cases of infective endocarditis have been reported. A case involving a 69-year-old man with colon cancer and hemicolectomy 14 years previously, without recurrence, is reported. A diagnosis of native mitral valve endocarditis was established on the basis of clinical presentation, characteristic echocardiographic findings and pathological specimen examination after urgent valve replacement.A viridansendocarditis appears to be particularly virulent, requiring a surgical approach in four of 10 cases reported and death in one of nine. Given the aggressive nature ofA viridansendocarditis and the variable time to diagnosis (a few days to seven months), prompt recognition of symptoms and echocardiography, in addition to blood cultures, should be performed when symptoms persist.

Established Infection

The antibiotics vancomycin, penicillin G, novobiocin, and oxytetracycline were examined for in vivo effectiveness against gaffkemia, the fatal bacterial infection of lobsters (genus Homarus) caused by Aerococcus viridans (var.) homari (formerly Gaffkya homari). Only vancomycin was truly effective against an established infection and then only when given at high levels (25 mg/kg lobster body weight) in the early stages of infection, prior to development of hemolymph bacterial numbers in excess of 3 × 104/ml or coincident hepatopancreatic bacterial levels of 1 × 107/g. Even massive cumulative doses (500 mg vancomycin/kg body weight), when given after establishment of maximum bacterial numbers, failed to impede the infection. Rates for the clearance of vancomycin from lobsters, established by using three different concentrations (25, 10, and 5 mg/kg body weight, respectively), were extremely slow and markedly concentration dependent. Twenty-five milligrams vancomycin/kg body weight injected prior to infection still gave a high degree of protection against challenge with the pathogen 50 days later in lobsters held at 15 C. One milligram vancomycin/kg body weight administered prior to infection gave complete protection against gaffkemia for 15 days after the antibiotic had been administered.

The Hemolymph Bactericidin of American Lobster (Homarus americanus): Adsorption and Activation

Aerococcus Viridans

The bactericidin of American lobster (Homarus americanus) hemolymph was adsorbed readily by representatives of two bacterial genera: a nonpathogen, Pseudomonas perolens, and the lobster pathogen Aerococcus viridans (var.) homari. Activation of the bactericidin by factor(s) secreted by the hemocytes can occur before adsorption and also after adsorption by bacteria. Although the lobster pathogen A. viridans (var.) homari is unaffected by the activated bactericidin, this lack of effect is not related to adsorption since this bacterium adsorbs the bactericidin as readily and completely as does the susceptible nonpathogen. Key words: lobster, Homarus americanus, plasma bactericidin, adsorption and activation, hemocytic activator, Pseudomonas perolens, Aerococcus viridans (var.) homari
