Mammary glands of 6 lactating Holstein cows were inoculated with Haemophilus somnus strain 43826. Three cows developed chronic mastitis and shed bacteria for up to 1 year. Three cows developed acute gangrenous mastitis, with evidence of bacteremia and endotoxemia. Cows with gangrenous mastitis had lower somatic cell counts early after inoculation in affected quarter secretions compared with those in cows that developed chronic mastitis. Cows with gangrenous mastitis developed hypocalcemia, hypoalbuminemia, azotemia, hyperbilirubinemia, mildly increased serum aspartate aminotransferase and creatine kinase activity, and a marked neutropenia with a degenerative left shift. Histopathologic examination of gangrenous quarters revealed edema, necrosis, and vascular thrombosis with few inflammatory cells. A limited survey failed to recover H somnus from dairy cows with clinical mastitis or from mammary secretions from 41 beef cattle at an abattoir.

We evaluated the effectiveness of 5-day antibacterial therapy for bacterial meningitis in children. The study group included 26 children from 2 months to 15 years of age, admitted with microbiologically confirmed bacterial meningitis in 1990-1993 and treated for 5 days. A historical comparison group of 49 patients treated for 8 to 15 days was used. Penicillin monotherapy (300 mg/kg body weight) was used for meningococcal and pneumococcal meningitis and ampicillin (300 mg/kg body weight) for Haemophilus influenzae b meningitis. On day 5 of therapy the activity of aspartate aminotransferase (AST), lactic dehydrogenase (LDH), creatine phosphokinase (CPK) and gamma-glutamyl-transpeptidase (gamma GT) in the CSF was determined by photocolorimetric assay and the concentration of creatine kinase BB (CK-BB) by ELISA. IL-6 was analysed using EIA technique and a cerebral ultrasound was performed at the time of the termination of the antibacterial therapy. The mean follow-up time was 1.3 years for children in the study group and 3.2 in the control group. The time of hospitalisation was shorter in children treated for 5 days (p < 0.005). Complete clinical recovery was 81% in the study group and 66% in the comparison group at the time of the termination of antibacterial therapy. No relapses occurred. The activity of AST, CPK, LDH, and gamma GT in the CSF had returned to normal by the 5th day of therapy, but almost a 7-fold higher concentration of CK-BB was registered. The concentration of IL-6 in the CSF decreased with the therapy from 1,800 pg/ml to 685 pg/ml but still remained high.(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this study was to compare the clinical, biological, and radiologic features of presentation in the emergency ward of community-acquired pneumonia (CAP) by Legionella pneumophila (LP) and other community-acquired bacterial pneumonias to help in early diagnosis of CAP by LP. Three hundred ninety-two patients with CAP were studied prospectively in the emergency department of a 600-bed university hospital. Univariate and multivariate analyses were performed to compare epidemiologic and demographic data and clinical, analytical, and radiologic features of presentation in 48 patients with CAP by LP and 125 patients with CAP by other bacterial etiology (68 by Streptococcus pneumoniae, 41 by Chlamydia pneumoniae, 5 by Mycoplasma pneumoniae, 4 by Coxiella burnetii, 3 by Pseudomonas aeruginosa, 2 by Haemophilus influenzae, and 2 by Nocardia species. Univariate analysis showed that CAP by LP was more frequent in middle-aged, male healthy (but alcohol drinking) patients than CAP by other etiology. Moreover, the lack of response to previous beta-lactamic drugs, headache, diarrhea, severe hyponatremia, and elevation in serum creatine kinase (CK) levels on presentation were more frequent in CAP by LP, while cough, expectoration, and thoracic pain were more frequent in CAP by other bacterial etiology. However, multivariate analysis only confirmed these differences with respect to lack of underlying disease, diarrhea, and elevation in the CK level. We conclude that detailed analysis of features of presentation of CAP allows suspicion of Legionnaire's disease in the emergency department. The initiation of antibiotic treatment, including a macrolide, and the performance of rapid diagnostic techniques are mandatory in these cases.
