Haemophilus aphrophilus isolated from blood.

H. aphrophilus was isolated from 11 successively cultivated blood samples of a male (72) with a fatal atypical endocarditis. Identification and differential diagnosis from Actinobacillus (Haemophilus) actinomycetemcomitans was done on the basis of phenotypic characters of the microorganism.

The authors describe the method of isolation and identification and differential diagnosis from a morphologically, cultivation and biochemically close species H. (A.) actinomycemcomitans. They discuss the problem of the taxonomic classification of the two species.

Ceftriaxon in the treatment of severe bacterial infections.

The efficacy of ceftriaxon (Rocephin Roche) therapy has been studied by our team in two groups of patients. The first one consisted of 10 children suffering from a diffuse purulent appendical peritonitis brought about by a mixed aerobe and anaerobe microbial flora, the second one comprising 7 patients with severe infections caused by problematic aerobe pathogens. The clinical effect of the treatment was good in 16 out of the 17 cases, in one patient it could not be evaluated. Even though a high degree of sensitivity to Rocephin could be demonstrated bacteriologically by the disc method in all the aerobe germs present, the results of titration of the bactericide capacity of the sera during treatment indicate the need for laboratory monitoring of the course of therapy of severe infections due to pseudomonas aeruginosa. Parenteral administration of Rocephin was well tolerated and the laboratory alterations seemin the course of therapy of severe infections due to Pseudomonas aeruginosa. Parenteral administration of Recephin was well tolerated and the laboratory alterations seen in the postoperative ileus due to strangulation and adhesions--cannot be recommended.

Central nervous system involvement in infectious mononucleosis with studies for Epstein-Barr virus.

Neurologic complications in three girls, aged four, fourteen and fifteen years, with infectious mononucleosis are reported. All three patients had meningoencephalitis, in two of them cerebellar involvement predominated, while the third patient had cerebral involvement with paresis of cerebral nerves. The diagnosis of an Epstein-Barr virus infection was established serologiccally and in the first patient also by the detection of the Epstein-Barr virus.
