During the course of infection, Yersinia enterocolitica invades tissues where macrophages and polymorphonuclear leucocytes (PMNs) constitute the first line of defence. As expression of virulence in Y. enterocolitica is governed in part by a c. 70 kilobase virulence plasmid (pYV), we investigated the influence of this plasmid on the interaction between Y.(More)
In vitro assays to quantify the bactericidal capacity of phagocytes require the removal of extracellular bacteria from the reaction mixture before intracellular bacteria are released from the phagocytic cells and counted. This may be achieved by using an antibiotic, such as gentamicin, which has a rapid bactericidal action coupled with limited ability to(More)
BACKGROUND Squamous cell carcinomas (SCCs) seem to have become more common recently. This study aims to check whether the increase is real and to review possible etiologic factors and problems in diagnosis. METHODS Patients with SCC were identified from anatomical pathology files over 30 years. The number and primary sites seen in the first 15 years were(More)
