The incidence of Malassezia furfur-related colonization of central venous catheters appears to be low but not negligible, which warrants the use of specific culture techniques.

Prevention of post-transfusion malaria remains a worrying problem. Until now it was very difficult to obtain homologous antigens, and immunologic methods used to detect malaria were expensive. We tested the ready-to-use Plasmodium falciparum prepared slides using the IFA (indirect fluorescent antibody) test on 866 selected potentially dangerous donors and known malaria cases. We found that it is a simple, quick, reliable and inexpensive method that can be easily used by blood banks and improve blood transfusion safety.

Résumé.De mars 1976 à décembre 1978, nous avons analysé 1039 écouvillons nasaux dans le but de dépister les porteurs sains d'amibes libres. Nous avons ainsi isolé 9 souches amibiennes dont une Hartmannelia vermiformis. Des 8 Acanthamibes restantes, une seule, O.R.L. 561 (Acanthamoeba hatchetti) est pathogène pour la souris, au même titre que les 2 souches identiques connues et A. culbertsoni. Summary.Isolation of free-living amoebae from the nasal mucosa of man. Potential risk.
