[Diagnosis of Chlamydia trachomatis--culture or enzyme immunoassay? Norwegian multicenter study].

Two EIA-tests (Chlamydiazyme, Abbott and Ideia, Celltech) were compared with culture for diagnosis of chlamydial infection in 1,185 patients from four different regions in Norway. The EIA-tests showed only minor differences in prevalences between the different regions (Chlamydiazyme: 4.1% to 5.4%; Ideia: 5.1% to 5.7%), but the agreement between the EIA-results was not satisfactory. 4.6 per cent of the specimens from Trondheim were culture-positive, but only 2.0% of the specimens from the other regions were culture-positive. Compared with the results from cultures from Trondheim (n = 349), the sensitivity, specificity, positive and negative predictive values for the EIA-tests were: Chlamydiazyme: 81.3%, 98.2%, 68.4% and 99.1% (81.3%, 96.4%, 52.0% and 99.1% without blocking test); Ideia: 93.8%, 98.5%, 75.0% and 99.7%. Culture should not be used as a routine method for detection of chlamydia in specimens sent by post without cooling.

Congenital malaria in Scandinavia.

A case of Plasmodium vivax malaria in a 3-week-old infant, born in Norway of a Pakistanian mother, is reported. The child was admitted with a febrile illness of unknown origin, persistent vomiting, reduced body weight, thrombocytopenia, elevated total level of IgM, and a slightly positive specific IgG antibody titer. The mother had malaria during the puerperium, and febrile episodes 6-8 weeks before parturition. This is the first case of congenital malaria reported from Scandinavia.

The comparative in vitro activity of spiramycin and erythromycin against Norwegian bacterial isolates.

The in vitro activity of spiramycin and erythromycin has been determined by an agar diffusion method against relevant clinical isolates. Generally, erythromycin was more active than spiramycin on a weight-for-weight basis. Spiramycin showed only moderate activity against Haemophilus influenzae and Streptococcus pyogenes. Gonococci were sensitive in vitro to both agents. Many erythromycin-resistant staphylococci were sensitive to spiramycin.

Endocarditis caused by Pasteurella multocida.

A 51-year-old previously healthy man developed endocarditis with low grade fever, aortic insufficiently and multiple arterial emboli. An atypical strain of Pasteurella multocida was isolated from each of 3 consecutive blood cultures. Protracted treatment with high doses of penicillin G was necessary to eradicate the infection. Following resection of the damaged aortic valves and implantation of a valve prosthesis, the patient recovered. P. multocida should be regarded as one of the possible causes of subacute bacterial endocarditis.

Neonatal osteomyelitis caused by group B streptococci.

A 3-week-old infant with a group B streptococcal osteomyelitis is described. On admission swelling and fluctuation were combined with local erythema in the right ankle joint region. Group B streptococci, type Ib, were isolated both from blood and from the local focus in the ankle. The diagnosis was further confirmed by X-ray examination showing a lytic lesion in the talus. The child was successfully treated with penicillin, initially in combination with kanamycin.
