Spawning behaviour of Allis shad Alosa alosa: new insights based on imaging sonar data.

Spawning behaviour of Alosa alosa was observed by high resolution imaging sonar. Detected clouds of sexual products and micro bubbles served as a potential indicator of spawning activity. Peak spawning time was between 0130 and 0200 hours at night.

Streptococcus milleri group infection associated with digestive fistula in patients with vascular graft: report of seven cases and review.

We described seven patients with Streptococcus milleri group aortic (six patients) or vena cava (one patient) graft infection secondary to a vasculo-digestive fistula. Time between vascular graft setting and first clinical signs varied from eight months to more than thirteen years. Six patients had fever.

[Bartonella endocarditis on native valves. Apropos of 2 cases].

The authors report two cases of Bartonella endocarditis in native valves. The first case was a 15 year old North African Girl who lived in poor social conditions and was admitted to hospital with pyrexia and congestive heart failure. Investigations revealed massive mitral regurgitation due to ruptured chordae tendinae, vegetations on the pulmonary valve with severe pulmonary hypertension due to persistent ductus arteriosus.

[Nocardia respiratory infection in patients with chronic obstructive lung disease].

Pulmonary nocardiosis is a respiratory infection which is usually described in the immunocompromised. We report three cases in patients suffering from chronic airflow obstruction. In two cases there was a parenchymal disorder and in one case bronchial suppuration without involvement of the alveolar region.
